In this article, I have listed the best online stores/pharmacies where you can get Phentermine from.

If you are a US resident, you can buy Phentermine from the comfort of your home if you have a prescription for it. However, to get Phentermine in the UK, you must consult a diet clinic and enroll in a weight loss program.

But why can’t you get this appetite suppressant over the counter? The answer to this query and the complete procedure to get prescription medicine online is listed in the sections below.

So, keep reading to find out how you can buy Phentermine online;

Do You Need A Prescription For Phentermine For Weight Loss? (Where?)

Yes, you need a prescription to buy Phentermine as it is not approved for over-the-counter sale. Phentermine is a stimulatory compound. Its appetite-suppressive effect results from neural stimulation and the release of stress-mediated neurotransmitters and hormones. It also has the potential for abuse and dependency in case of prolonged use or overdose.

Due to these severe consequences, getting a prescription from a registered health practitioner is compulsory to get Phentermine for weight loss.

You can get this prescription from your primary healthcare office or google search for ‘doctors who prescribe Phentermine near me.’ Also, some clinics provide telehealth services to get doctors’ consultations and prescriptions.

However, each state has different laws about telehealth prescriptions, and mostly, you would need to go to the clinic in person, at least for the first appointment.

In the UK, general physicians are not allowed to prescribe Phentermine, and you can only get a phentermine prescription from a registered slimming clinic.

Phentermine Without Prescription- Here’s Why You Should Never Buy It

Before I head to the pharma stores that supply Phentermine on online orders, I must mention that never buy from a store offering you Phentermine without a prescription. This precaution has three reasons;

  • First off, only a knowledgeable health provider can tell if a stimulatory product like Phentermine is suitable for you. Taking it without a thorough checkup can lead to health adversities.

(This article describes in detail when Phentermine can be dangerous)

  • Suppliers who offer prescription drugs without Rx scripts are dishonest, unauthorized merchants, and you cannot trust such people for the quality of drugs they will provide you.

It is a hundred times better to stick with the doctor’s guidelines and continue weight loss through dietary changes and exercise if he’s not prescribing Phentermine than using a counterfeit drug.

  • And last but not least, you cannot take Phentermine without a prescription according to DEA, FDA, and NHS rules. It is a controlled substance (Schedule IV drug in the USA) (Class C drug in the UK) due to its potential for abuse.

Hence, having it the wrong way (dosage/frequency) may get you in trouble.

That being said, the following are some of the most popular places where you can buy Phentermine online in the US and UK.

Where To Buy Phentermine Online For Weightloss?

Yes, you can buy prescription drugs without leaving your home. In the section below, I have listed some online drug stores that supply Phentermine online;

Buy Phentermine Online In the USA

When you have the prescription, you can buy Phentermine or Adipex-P (the branded form of Phentermine) from online pharmacies in the US.

Here is where and how you can do that;

1. Blink Health

Blink Health is a digital Rx provider with more than 35000 US pharmacies. With this service, you can order prescription medicines like Phentermine at your doorstep without even paying a shipping fee.

Also, if you do not have a prescription, Blink can help you connect with a registered physician to get one.

  • To buy Phentermine, you need to transfer your prescription to Blink. For that, ask your doctor or your current pharmacy to transfer your prescription to BlinkRx. Prescriptions can be transferred via fax or phone.
  • In the next step, after Blinkhealth confirms the receipt of your prescription, you can place your order and pay online.
  • Once the order is confirmed, you will get your medicine delivered within 4-6 business days.

Both Phentermine tablets and capsules are available, and you can choose the number of pills starting from 7 per pack. Tablets come in a potency of 37.5 milligrams, while capsules are available in three different potencies.

Interestingly, the low-potency capsules cost a few pennies higher than high-potency pills!

Here is the price you will pay when using this online Rx service;

2. Honey Bee

Honey Bee is an online pharmacy that connects consumers with drug suppliers.

The best thing about this service is that you only need to provide the contact details of your current pharmacy, and they will obtain and verify your prescription on your behalf.

  • First, select the medicine potency, quantity, and pill type and place an order.
  • Honey Bee will verify your prescription before order confirmation.
  • Contact your doctor’s office and request them to send your prescription to Honey Bee via e-prescription, fax, or phone. If your prescription is at a local pharmacy, provide the name and phone number of the pharmacy as you place your order. The online pharmacy will contact them and get the prescription on your behalf.
  • Your medicines will arrive in 2-3 business days.

You can get 30 to 90 phentermine tablets and capsules through this service.

With HoneyBee, you get different pricing options as multiple manufacturers sell their products through Honey Bee.

Here is the price range listed for generic and branded (Adipex-P) phentermine pills;

Although Honey Bee supplies OTC drugs to all 50 states, they do not have licenses for prescription drugs or controlled substances like Phentermine for all states.

Hence, check their shipping information page to find out if they are authorized for phentermine delivery at your address.

3. Walgreens

Walgreen is another trusted name when it comes to buying prescription drugs online.

Phentermine 37.5 mg capsules are available at this pharmacy by the brand name Adipex-P.

Walgreen offers you up to 90 days of Rx refills, and you can choose from pickup and delivery options. The process is simple;

  • Sign in to your Walgreens account. Walgreens mobile app is a convenient resource to place and track your orders.
  • Look for your required potency and then place an order.
  • Transfer your prescription via your physician’s office or your current pharmacy and get your medicines delivered to your home.

4. Empower Pharmacy

Empower pharmacy is another online drug store to buy Phentermine. It offers more dosage strength options compared to other pharmacies. Phentermine HCL pills are available in the following dosage strengths;

To get Phentermine from Empower pharmacy, the process is pretty much similar to as it is for Honeybee and Blinkhealth. You’ll need to ask your doctor to transfer your prescription via call or fax, then confirm your order with the pharmacy.

Buy Phentermine Online in the UK

You will not get a phentermine prescription from your physician in the UK. Instead, you need to enroll in a weight loss program offered by authorized diet clinics. These clinics in-offer both in-person checkups and remote consultations with weight loss specialists.

These programs often include anorectic drugs like Phentermine which are provided as a part of therapy. Clinics like Bodyline, London Slimming Clinic, and Diet UK can help your weight loss journey.

Where Can I Buy Phentermine And Diethylpropion?

Like Phentermine, you can get Diethylpropion from the Rx providers and weight loss clinics, as above-mentioned.

Likewise, prescription transfer and verification are necessary because Diethylpropion is also a prescription drug and a controlled substance.

Following is the pricing structure for buying Diethylpropion from these stores;

US pharmacies

You can get Diethylpropion from BlinkRx in the form of quick-release and delayed-release tablets, as suggested by your doctor.

As quick-release tablets have a sudden impact, they are only available in low potency (25 mg). However, extended-release tablets come in 75mg potency. You can buy packs of 15 to 90 tablets as per your requirements.

Diethylpropion is available in its branded form, “Tenuate,” at Honey Bee. They supply up to 90 pills of 25mg or 75 mg potency, but you must possess a prescription.

You can get Tenuate at the following prices;

Empower Pharmacy supplies Diethylpropion HCl as generic pills. Both immediate-release, low potency (25 mg) and controlled-release tablets, high potency (75 mg), are available.

At Walgreens, Diethylpropion is available by its generic name as well as in branded form (Tenuate). In both forms, you can get 25 mg or 75 mg tablets.

UK diet Clinics

Only authorized weight loss clinics can prescribe and supply Diethylpropion in the UK. Just like Phentermine, you need to enroll in a diet program, and your slimming doctor will analyze your health conditions to see if you qualify for prescription anorectics.

If prescribed, Diethylpropion will be provided by the clinic.

But Can You Take Diethylpropion With Phentermine? Is it safe?

No, you should not take Phentermine with Diethylpropion because both are stimulatory drugs, and combining them can result in severe side effects.

As both Diethylpropion and Phentermine are anorectic drugs, and research proves that they are effective for restricting calorie intake and losing excessive weight.

So, one may think of using them together to speed up the weight loss process.

But looking at the side effects, I can affirm that it is NOT a good idea!

Chemically, these are sympathomimetic amines that affect neural secretions, causing an increase in stress hormones and loss of appetite. Though these stimulatory disruptions to suppress hunger are safe when the dose is small and used for a short term.

However, taking them together is like taking a high dose, and both drugs adversely affect health when overdosed. It is like putting yourself at risk of health damage.

That is why I would suggest you take one of them at a time.

Here are some of the side effects common to both drugs;

1. Mild Side Effects

As both drugs belong to the same group and affect the body systems similarly, their side effects are also similar.

The following are usual side effects that users report even when used according to prescription in short-term;

  • Headaches
  • Nausea and gut unrest
  • Dry mouth and thirst
  • Insomnia
  • Nervousness or anxiety

If you start taking these appetite suppressants together, the intensity of these side effects can become manyfold.

2. Increased Risk of Cardiovascular Problems

Stimulatory drugs are a potent risk factor for heart issues. Research proves that Phentermine and Diethylpropion tend to increase heart rate and blood pressure.

Increased blood pressure makes you a hypertension patient over time and also leads to cardiac problems like angina, heart arrhythmias, etc.

3. High Chances of Developing Psychosis

Besides damaging physical health, nervous system stimulants are a risk factor for your mental well-being. These substances often cause short-term anxiety, which eventually leads to psychosis if the symptoms persist for a long time.

Phentermine is also associated with cognitive dysfunction and psychosis in many case studies. For instance, a 25-year-old Asian girl who took Phentermine for weight loss ended up in a psychological ward due to psychotic episodes and social impairment.

Similarly, cases of psychosis are enlisted in diethylpropion safety records. A woman of 36 developed paranoid psychosis by using high doses of Diethylpropion.


Phentermine can help you restrict your food intake if you struggle with binge eating. However, it is a stimulatory drug, and you need a complete checkup before getting a prescription.

With a prescription in your hand, you can get Phentermine from local or online pharmacies in the USA. Drug suppliers like Blink Health, Honey Bee, Walgreens, etc., offer easy pickup facilities, and you can also get your drugs delivered to your home.

In the UK, however, phentermine prescription is rare and only available from authorized weight loss clinics.
