How exactly should you use Adipex slimming capsules to lose as much weight as possible?

The answer is quite simple, and you will find it in this article.

We did our best to gather and process all the information available in official sources, on the forums and doctors’ recommendations to help you understand everything about this drug. We noticed that the majority of people are aksing answers to just a few questions.

If you are one of such people, find out now about Adipex side effects, Adipex results and Where to buy Adipex, without reading the entire article.

Besides, we have provided many other important facts about Adipex that you should keep in mind when using this drug to get slim.


First and foremost, Adipex (Adipex-P, Adipex 37.5 mg, Adipex 75, Adipex Retard) is a prescription medication and you should be monitored by a doctor, before during and even after you jump into the slimming course.

It is a strong and habit-forming medication, which is believed to be addictive when taken longer than recommended.

If it is that “dangerous”, then why do doctors prescribe it and people use it so often?

Let’s see…

Why do therapists issue prescriptions for Adipex?

Well, the first reason is that all Adipex options are indeed effective hunger suppressants.

This means that these pills are capable of decreasing your desire to eat throughout the day.

Admit it, it’s a tough challenge to follow diet recommendations and any related food restrictions, because of hunger.

The active ingredient of Adipex P, Adipex 37.5 mg, Adipex 75, Adipex Retard and many other Adipex alternatives is Phentermine.

It enhances the amount of norepinephrine hormone and induces the “fight-or-flight” response.

What is that “fight-or-flight” response mechanism, you may ask and why does it help with the weight loss?

Well, dozens of processes take place in your body when this response comes in, namely a release of various hormones, which produce the following effects over your body:

  • Cortisol – increases your blood sugar and blood pressure levels.
  • Epinephrine – causes the release of glucose into your blood.
  • Cortisol – turns fatty acids into available energy.

So, now you know what exactly this weight loss medication does inside you and how it changes the way your body works to help you lose the excessive fat deposits.

Getting back to doctors, who prescribe Adipex and why they do it.

By the way, many of them are reluctant to prescribe the drug, some are not willing to take the responsibility for possible side effects, caused by their insufficiently accurate patient examination, while others don’t believe in miracles.

However, obesity remains a burning issue in different countries all around the world, and it’s a natural thing for a doctor to be willing to help his patients.

Just think on what’s going on…

The WHO published an article in 2018, which provided the following obesity world rates:

See? It’s scary…

So, if there is something that can help people lose weight, doctors have no other option but to give it to them.

Now that we understand why a doctor prescribes Adipex, it’s high time to get straight to the drug itself.

Adipex: active ingredient

Each Adipex pill contains 37.5mg of sympathomimetic amine Phentermine HCl (an equivalent to 30mg Phentermine base).

As you already know, this sympathomimetic amine has a pharmacological property to suppress appetite.

The highest anorexigenic effect is achieved 3-4 hours after the oral intake of the drug.

The duration of the anorexigenic activity depends on the dosage and can reach 24 hours.

Classification of Adipex (Phentermine)

Prescription Only Medicine

Pregnancy: Category B2.

In fact, Phentermine was developed by scientists as an antidepressant.

However, it did not have an effective antidepressant action, though its ability to affect appetite and mood of obese people turned out very significant.

Weight loss pills Adipex: indications for use

  • Weight loss in overweight patients with a BMI of 27 to 29.9.
  • A short-term therapy of obesity in patients with a BMI of 30 and above.
  • Adipex pills should not be prescribed to adolescents under 16 years old, elderly over 65 years and patients with severe kidney diseases.
  • Patients with a history of cardiovascular diseases should take these slimming pills with caution.

Please note!

The US is one of the few developed countries, where people have never used capsules and tablets containing Phentermine (e.g. Adipex-P capsules) as an obesity treatment in adolescents.

In contrast to the US physicians, Australian doctors administer Phentermine-containing drugs to children aged 12 years and older.

Therefore, namely Duromine containing Phentermine is the most popular brand name in Australia.

There are no Adipex-P slimming pills in Australia, AND there is no Duromine in the US, accordingly.

How does Adipex make you slim?

Well, everything seems very simple.

Eat right and exercise regularly.

But it really is not that easy, is it?

Most of us get ravenously hungry after a hard day’s work.

And sometimes we are so tired of our tasks that we cannot even imagine moving a finger, let alone hit the gym tired.

This is where Adipex slimming capsules can help you.

No, it’s not a simple energy booster – it will also suppress your hunger, as you know.

Sum these actions up – and you get the perfect slimming formula!

People who have suffered from obesity for many years can have many health risk factors.

That is why it is so essential for them to quickly drop off weight.

Adipex provides physical and chemical results, which bring benefits for your health.

You will get the following physical effect after the first intake of the pills:

  • Hunger relief;
  • Weight loss;
  • Energy boost.

You’ll be able to burn fat very quickly with Adipex, because the hormones, the release of which it triggers, help you burn more energy and fat during your daily activities.

Adipex: two forms of popular slimming capsules

Do you know what the letter P stands for in Adipex-P?

It’s for the active ingredient – Phentermine.

Unfortunately, this substance has been banned in Europe since the 70s.

Therefore, the Europeans have the opportunity to get the generic versions of Adipex-P, and not the brand medication.

This powerful appetite suppressant is currently available in two dosage forms:

  1. Hard capsules
  2. Tablets with a film coating.

In both dosage forms, the active ingredient is mixed with hydrogen chloride compound, which is intended to facilitate the regulation of drug solubility and increases the stability of the pills and caps during storage.

Brand Adipex capsules and tablets have their own distinctive features, which make them easy to recognize.

For example, the capsules have the following properties:

  • white body
  • blue cap
  • opaque shell
  • two dark-blue stripes on the body
  • markings “Adipex P” and “37.5” on the cover.

As for the tablets, these come in a blue-white color, and have a marking “Adipex P” on one side, and “9” on the other.

You will find Adipex in bottles, which can contain:

  • 100 capsules
  • 30, 100 or 1000 tablets.

The gelatin shell of the caps dissolves rapidly in the esophagus (in about 5-10 minutes), thanks to which the onset of the anorexic action is not delayed.

Both capsules and tablets are absorbed in the gastrointestinal tract for approximately 3-5 hours.

Adipex dosage


You should take the pills early in the day – before, together with a small healthy snack or 1-2 hours after a rich meal.

In fact, the caloric content and frequency of meals do not affect the anorexigenic effect of the drug.

The highest daily dose of Adipex is 37.5mg (one slimming pill).

This dose can be divided into two intakes, if you choose to get namely the pill form.

Capsules should not be opened.

If you open an Adipex capsule before using it, it may release the active substance (Phentermine) at once, increasing the risk of side effects.

The dosage that you will be prescribed depends on such factors, as your:

  • degree of obesity,
  • age,
  • associated diseases.

You can divide the tablets into two halves, 18.75 mg each.

Dose of 18.75 mg per day can be sufficient for some patients to reduce their appetite.

You can also be advised to take two halves of the pill per day, to increase the rate of weight loss and ensure a longer appetite suppression (i.e. help fight evening and night binging).

Adipex 37.5 mg is the maximum dose, which can be taken per day.

Patient’s wish to lose weight quickly can encourage them to increase the daily dose.


And that’s that!

Adipex-P and Adipex 37.5 mg

Literally, these are two names of the same medication.

Yes, you can find generic version, which are named Adipex 37.5 mg, but these contain the same amount of Phentermine as the branded Adipex-P does, namely 30 mg.

The release rate of both medications is equal, just like the action, side effects and results you can achieve while using them.

The following two Adipex versions differ from these two by both, the release rate and the amount of active ingredient they contain.

Keep reading to make an informed choice and pick the form that suits you the most.

Adipex Retard and Adipex 75

These Adipex options contain a smaller amoutn of the active ingredient, compared to the previous two, and namely 15 mg of Phentermine.

The second difference is the release rate of the active ingredient.

While Adipex-P and Adipex 37.5 mg provide an immediate release of the substance, Adipex Retard and Adipex 75 ensure a slow release of the drug.

The second option is usually preferable, since a slow release and absorption of the medication allow extending the duration of the appetite suppression and help you cope with hunger until the end of the day.

While a smaller amount of the active substance might be considered a drawback, it actually provides several benefits, such as:

  • lower risk of severe side effects
  • possibility to take two doses, when needed
  • possibility to adjust the dosng regimen to 2 caps a day (one very early in the morning, another at least 8 hours before bedtime) to ensure a “hungerless” evening
  • possibility for a gradual exit from the treatment, thus ensuring lack of possible withdrawals

Adipex overdose

Overuse and exceeding the maximum time of use (3 months) of this drug may cause overdose and physical dependence.

Second to most important factor of overdose is a combined use of Adipex-P psychostimulant with such substances as:

  • CNS stimulants,
  • weight loss pills,
  • medications that affect the cardiovascular system.

Constant use of more than one diet Adipex pill significantly increases the risk of overdose and can lead to psychological dependence.

If you accidentally or intentionally took two pills, it can result in:

  1. Slight increase of Adipex anorexigenic action.
  2. No difference, compared to taking just one pill.
  3. New side effects or their worsening.
  4. Overdose and, in some cases, hospitalization.

The interval between consequent doses should be approximately 24 hours.

If you forget to take Adipex in the morning, avoid doing it in the afternoon, all the more in the evening.

Taking the drug 5-7 hours before bedtime often leads to such side effect, as insomnia.

True, excessive Adipex dose does not always lead to an overdose, but it usually causes a sharp increase in blood pressure and heart rate.

Since obese patients often have hypertension, you need to have your blood pressure checked before you start using the drug and continue with the check-ups during the following visits.

If you have hypertension, you should take Adipex with caution.

In your condition, use of more than 1 diet pill a day can lead to a heart attack or stroke.

If you are planning to start Adipex, make sure that you are not taking certain medications.

  • If you take Adipex (Phentermine) with drugs, which have anorexigenic effect, it significantly increases the risk of overdose and side effects. Therefore, Adipex diet pills should not be taken with other drugs for weight loss.
  • Do not take Adipex diet pills with other central nervous system (CNS) stimulants. For example, MAO inhibitors may enhance Adipex’ sympathomimetic effect and lead to a hypertensive crisis.

This weight loss drug can interact, moderately or severely, with over 100 drugs and their generics.

Of course, it is impossible to memorize all possible drug interactions.

However, during the consultation with your doctor about Adipex, you should mention every single medication that you take, even occasionally.

Below, we present you the list of possible signs of Adipex overdose:

  • respiratory failure,
  • chest pains,
  • changes in heart rate,
  • hallucinations,
  • tremors,
  • temporary loss of consciousness.

Seek help from your doctor or poison control center, if you notice any signs of an overdose.

Adipex results

One-month use of Adipex-P pills can result in a 5% weight reduction.

This is a very important moment for any anti-obesity campaign.

When you visually see the treatment results and notice a before and after Adipex difference, you will get a strong motivation for further weight loss.

People, who increase the intensity of physical exercises to the max and refuse junk food (high in bad fat and simple carbohydrates), usually achieve better results with the drug.

If you are responsible and ambitious enough, you can reduce your weight with Adipex-P by more than 15%.

A lot of success stories and reviews about Adipex-P confirm the data of clinical studies that have been conducted in the last century.

These diet pills on the average reduce weight by 10% in just 2-3 months.

How to take Adipex for best results?

Just taking Adipex is very unlikely to help you achieve any HUGE result.

Yes, you will probably lose some weight, or even more than “some”, if you are used to eating huge portions of food, and then lessen their size during the treatment.

However, Adipex alone is definitely far from providing 100% efficient weight loss.

You should use the pills in a complex company with a healthy diet and daily exercises.

The good thing about the drug is that it helps to get rid of fat tissue, without affecting your muscles.

Therefore, nutritionists and doctors recommend staying physically active and even do some strength exercises to keep the muscle tissue toned.

Besides, any physical activity will make your body burn calories.

So, you take one Adipex P pill in the morning, and it makes you feel like you’re not hungry at all during the entire day.

This means that you can focus on such important things, as:

  • your work,
  • your inner development,
  • your body improvement.

All these without having to constantly think about food.

At that, you do need to eat, because your body does need high-quality fuel to cope with the weight-loss-in-progress situation.

So, when it’s time to eat, you may take a small portion of healthy food, prepared beforehand.

Don’t forget about drinking more water than you are used to and have some healthy snacks (nuts, fruit and yogurt) between the main meals.

This regime will completely change your lifestyle and you will find it very easy to keep the diet further.

Thus, the weight loss results stay with you even after you finish taking Adipex P diet pills.

It’s a natural thing to wish keeping that normal body weight for a long time after a weight loss course.

As we know, obesity is a chronic disorder and it is very hard to get rid of it.

So, use this appetite suppressant as a kick-starter, and change your lifestyle to lose excess weight and maintain the result.

Nourish your motivation and willpower, and great weight loss results are not that long to wait.

And don’t get back to the way you used to eat and be passive in your pre-Adipex life.

After all, you put so much effort into losing the undesirable kilos…

Adipex contraindications

One important aspect to consider before you start an Adipex course is its contraindications.

If your doctor does not have sufficient knowledge about this anorectic drug, he might tell you that your diabetes and well-controlled hypertension are contraindications its use.

But this is not true. These conditions simply require a careful monitoring and drugs dosage adjustment.

However, before you include Adipex pills in antihypertensive and (or) anti-diabetic therapy, don’t forget to ask your doctor about such adjustments, both in dosage and administration schedule – to avoid unpleasant consequences.

These slimming pills should not be prescribed to people whose obesity is complicated by such health conditions, as:

  • High intraocular pressure
  • Severe artery disease
  • Overactive thyroid
  • Poorly controlled hypertension
  • Mental disease (including anxiety, depression)
  • Moderate or severe cardiovascular disease
  • Drug and (or) alcohol dependence
  • Diseases for the treatment of which monoamine oxidase inhibitors are used.

Adipex safety

Of course, like any other medication, Adipex weight loss pills can cause side effects, allergies, overdose and even addiction.

But it doesn’t mean that its safety profile is unsatisfactory.

Dozens of clinical trials were held on the pills safety and effectiveness.

The active ingredient of the drug proved its safety in overweight therapy during such long-term clinical studies.

High ratio of efficiency and safety is a major factor that affects the popularity of this anti-obesity drug in adults and adolescents over 16 years.

Using Adipex as short-term adjunct (no more than 12 weeks) in therapy of exogenous obesity is safe for obese patients’ health.

Despite the fact that Phentermine is actively metabolized in the liver and excreted by the kidneys, it has no toxic impact on these organs, when you observe the prescribed dosages.

Conclusions to safety studies report that Adipex is well tolerated, has low toxicity and good safety profile.

At that, the manufacturer, Teva Company, does care about the drug safety and still collects information about side effects and drug interactions, changing their list from time to time.

So, it is always useful to check their list before you take the first pill.

Adipex diet pills: side effects

You already know and probably read plenty of information on online platforms about the side effects, which can manifest during the use of Adipex weight loss pills.

As a rule, side effects of these slimming pills are mild and manifest at the initial stage of therapy for overweight or obesity.

Doctors recommend using Adipex P diet pills for a maximum of 8-12 consecutive weeks.

That is why the drug does not cause any long-term side effects.

However, you must keep in mind that a misuse or overuse of Adipex P drug can cause such side effects as addiction and withdrawal syndrome.

Since this anorectic works in your central nervous system, it is logic to expect some side effects from this system of your body.

The most typical CNS side effects of Adipex are depression, mood swings, excitation, nervousness, dizziness, headache, difficulty falling asleep and other psychotic reactions.

Another important system, which can be significantly affected by this drug, is your cardiovascular system, and namely your blood pressure and heart rate.

In turn, these alterations in their normal rates can provoke such side effects, as chest pain, tachycardia and hypertension.

Possible gastrointestinal side effects are nausea, vomiting, frequent or difficult bowel movements.

As for the allergic reaction to Adipex-P, it is characterized by redness and itching.

In some blogs or on some forums, you can find people mentioning such Adipex side effects, as hair loss, acne and irregular menstrual cycle in women.

Most likely, these are not directly related to the use of this anorectic.

Of course, each body works differently and unusual reactions are possible.

However, no reports of hair loss were recorded during the clinical trials on the drug safety.

If you have never used appetite suppressants, it is advisable to get a small package of Adipex-P and make sure that it does not cause any severe side effects.

You can try to ask your doctor for a sample pack or address to a weight loss clinic, and ask, whether they provide such opportunity for a “tasting”.


Adipex may promote cardiovascular diseases and their aggravation.

Therefore, severe cardiovascular side effects (hypertension, tachycardia, chest pain) require immediate termination of these pills.

People on Adipex often experience dizziness, headache, insomnia, or anxiety.

If these side effects are moderate or severe, you might need to lower the daily dose or start taking the drug every other day.

Dry mouth, constipation and diarrhea are among the most frequently reported side effects.

It is noteworthy that constipation and diarrhea can occur because of changes in your diet, rather than due to Adipex.

Men and women should take note that this weight loss drug could worsen their sexual function (or significantly improve!).

Endocrine side effects of Adipex are reversible and disappear after the end of obesity drug therapy.

How fast do Adipex tablets work?

We already mentioned in the part “Adipex: active ingredient” that:

  • The highest anorexigenic effect is achieved 3-4 hours after the oral intake of the drug.
  • The duration of the anorexigenic activity depends on the dosage and can reach 24 hours

And we know that the active ingredient start being absorbed in 5-10 minutes after the intake.

Some people report of an almost immediate action, when their hunger decreased and an energy boost hit them in about 20 minutes after the pill administration.

At the same time, some users reported that it took their bodies several days to a week to actually show any significant response to the drug use.

So, if you don’t feel like the drug does nothing for you, even a couple of days after the course initiation, don’t give up.

Give it some time and continue taking it.

If nothing happens in 10 days of use, we’re sorry, your body is not responsive to the drug action and you should try alternative weight loss meds.

Adipex alternatives

So, if it turns out that you are contraindicated to the use these slimming pills and any other weight loss drugs that contain Phentermine, your doctor can prescribe you Orlistat pills.

Weight loss pills Orlistat were included in the ARTG in 2000.

You can find Orlistat pills for sale under the trade names Alli and Xenical.

Each Alli pill contains 60 mg of Orlistat, and each Xenical pill contains 120 mg of Orlistat.

In contrast to Phentermine, Orlistat does not suppress appetite.

It prevents the absorption of fats in the gastrointestinal tract and promotes their excretion from the body unchanged.

Adipex generics

To date, the global pharmaceutical market has dozens of different Adipex generics.

Like the original Adipex, its generic drugs contain 37,5 mg of the active ingredient Phentermine hydrochloride (HCl).

These anti-obesity medications are available in two dosage forms:

Capsules for oral administration

Tablets with a film coating.

On the American market, generic versions of the drug are supplied by popular pharmaceutical companies, such as:

  • Vintage
  • Aurolife
  • Lannett
  • KVK Tech
  • Elite Labs
  • Sun Pharm
  • Ken Lifescience
  • Polygen Pharms.

In the US, Adipex generics are sold only under the non-patented name Phentermine HCl, yet they can be available under different names in different countries.

For example, in Chile, you can get generic Adipex under the brand name Elvenir.

What does the FDA say about Adipex?

Generic Adipex has been confirmed by the FDA as a safe medication to control weight.

While cheap Adipex is safe for people, it is important to follow the recommendations for the dosing schedule and not extend the recommended duration of the course.

Price of Adipex-P

Despite the fact that Adipex-P pills are quite expensive, most people are interested in their effectiveness, rather than in the price of obesity treatment.

Price of Adipex-P (Phentermine) varies considerably in pharmacies all over the world, and it is not always clear why.

We can trace several principles in the process of price formation for Adipex-P diet pills:

  1. The cost is formed from the sum of all production costs
  2. Formation of Adipex-P price is based on the evaluation of the drug’s usefulness

So what influences the cost of Adipex-P in different countries? The answer is simple: everything.

Pharmacological and intermediary companies say that the prime cost of Adipex-P weight loss drug includes:

  • development or purchase of the active ingredient (Phentermine) and other drug components;
  • previous developments and attempts to create similar products;
  • clinical trials;
  • production and registration of the drug;
  • marketing promotion and advertising of the drug;
  • shipping and intermediary services.

All this is true, and only a few questions arise:

What are the salaries and bonuses of top managers

How high are payments to officials in some countries

What is the real prime cost of Adipex-P drug

What proportion has marketing and advertising in the final drug price

Why so few companies are engaged in the development of principally new drugs

Where is the limit to the cost of the drug

Why is the seller selling products, which are selling well, and not those that help?

Seller always tends to overrate the cost.

There is no such thing for sellers, as “extremely high price”.

High prices for this weight loss medication affect the drug availability for vulnerable categories of citizens in various countries around the world.

For the poor, spending big money for Adipex-P reduces other health care costs.

Many states artificially constrain growth in drug prices or even take upon themselves part of citizens’ expenses for pharmacological obesity treatment.

Some governments control regulations in health care.

This allows setting a price limit for drugs and it serves as a barrier to manufacturers for raising prices.

One way to reduce the cost of weight loss drugs is the replacement of proprietary products to alternative, non-prescription or other generics.

In industrialized countries (Belgium, France, etc.), the cost of generic drugs is compared with the price of the original ones.

For example, in France the limit (maximum) price (from producer) of a generic drug should be 50% lower than the original price of the medicinal product.

The European Generic medicines Association (EGA) opposes this practice, stating that the original medicines manufacturer can generally eliminate generic competitors from the market by constantly reducing costs.

Many countries around the world, directly or indirectly, regulate Adipex-P prices. The most popular methods of pricing Adipex-P drug are mixed ones (a combination of freely assignable and regulated prices).

Very often, the cost of Adipex-P is compensated in terms of health insurance systems.

Insurance companies usually reimburse the cost of prescription drugs and monitor the main stages of the drug passing from the manufacturer to the patient.

Obesity in the world’s population has reached epidemic proportions.

Reducing prices for Adipex can facilitate greater access to drugs for people with obesity worldwide.

Fighting obesity and weight loss in the world’s population will lead to a longer and more comfortable life.

Where can I buy Adipex

As mentioned, you can get Adipex P 37.5 mg weight loss pills in conventional US pharmacies with a prescription only.

In order to get a prescription for Adipex diet pills, medical examination is recommended.

As for generics, Adipex in the US is available under the international nonproprietary name Phentermine Hydrochloride.

During our thorough research, we stubmled across a huge weight loss community and studied well their “sell” section. We have identified one seller, who offers a worldwide delivery of Phentermine-containing and other weight loss medications.

It offers two branded medications, which contain Phentermine as a resin complex, one of which is Adipex 75 and one of Phentermine generic versions, Phentermine 37.5mg.

The positive feedbacks about both the seller and the products provide a positive feeling. However, it is important that you only buy any weight loss pills when you know for sure that you are not contraindicated to use them.

The information provided should not be used to substitute a doctor’s consultation. For full information, check out the patient’s leaflet and read it carefully. This information is provided for informational purpose only and should not be taken as a doctor’s advice.

Adipex suppliers

Unlike numerous Adipex suppliers in the USA, Adipex in the UK is supplied only online or by weight loss clinics.

If you are willing to reduce your weight under medical supervision, choose one of the slimming clinics, which has the right to supply Adipex (Phentermine).

Many clinics supply Adipex in the UK and thanks to their services many patients effectively lose their weight and improve quality of life.

However, not all obese people in the UK can afford obesity treatment in a specialized clinic.

For many of them, cost of full course for weight loss is very high.

In such cases, obese patients look for Adipex suppliers to treat obesity at home.

Many online pharmacies of the USA, Canada, and UK provide their Adipex delivery services.

At that, those suppliers, who provide the drug with a prescription only are the ones that sell the drug legally.

If any online drugstore or clinic offers you Adipex-P without a prescription, you have to note that you are geting it at your own risk, because such purchase will be illegal.
