Phentermine Online

How to Buy Phentermine Online

Many people look for sites where they can buy phentermine online, thinking it’s a good way to save money, time, and the inconvenience of going to a doctor. However, it is NOT legal for US residents to buy phentermine online.

The active ingredient in phentermine weight loss pills, phentermine hydrochloride, is classified as a schedule IV controlled substance in the United States and abroad ( 1 ). As a result, it is illegal and dangerous to purchase phentermine online.

The History of Phentermine Online

It has been illegal to buy phentermine online since 1999

In the early years of the internet, many online pharmacies capitalized on the new technology to sell phentermine and other prescription drugs online.

However, this was a risky business because the doctor never evaluated the patient and all medical information was self-report. As a result, potentially-dangerous drugs were being sold and distributed with little medical or legal regulation.

However, after a teenager fatally overdosed on medication purchased from an online pharmacy, Congress enacted The Ryan Haight Online Pharmacy Consumer Protection Act of 2008. This legislation made it illegal to deliver, dispense or distribute any controlled substance without conducting at least one in-person doctor’s visit ( 2 ).

So, when the Act took effect in April 2009, it became illegal to prescribe or buy phentermine online or via telemedince. The DEA and the US Justice Department are responsible for enforcing this legislation ( 3 ).

It is ILLEGAL and DANGEROUS to buy phentermine online.

Buying Phentermine Online in 2021

Is there any way to buy phentermine online?

It is NOT possible to buy phentermine online without a prescription. However, in some cases, you can fill out a valid prescription online after your doctor’s visit.

How to buy phentermine online:

1. Make a Doctor’s Appointment

If you want to buy phentermine, the first step is to schedule an appointment with your doctor.

Practitioners from a wide variety of specialties prescribe phentermine, but your primary care doctor (PCP, GP) is a good place to start since he/she typically tracks and evaluates your weight status. Some other patients also receive phentermine from bariatric doctors, gynecologists, or internists.

Unfortunately, there is still a strong stigma against phentermine, and not all practitioners are willing to prescribe this medication. Two of the main reasons are that:

  1. Phentermine is still widely associated with phen-fen, the dangerous cocktail that grew popular in the late 80s, and
  2. Phentermine is only a short-term treatment for obesity

As a result, many doctors favor guided lifestyle changes (diet, exercise), medically-supervised weight loss programs, or weight loss surgery instead of prescription weight loss drugs.

If you are having trouble finding a doctor to prescribe phentermine, search for local weight loss clinics. These clinics typically employ physicians that are more familiar with phentermine and its role in a successful weight loss journey, so they are likely to prescribe weight loss medication if you are an appropriate candidate.

As one phentermine user commented:

If your PCP isn’t open to allowing you to try them, research local weight loss clinics. I wish it wasn’t such a struggle to find open-minded doctors who truly understand this medication. Used properly it is a wonderful tool for people, and the majority do not have adverse side effects or get “addicted.” Someday the stigma will be lifted.

2. Ask About Phentermine

The doctor will ask you about your medical and weight history, plus discuss lifestyle changes

If you bring up phentermine, your doctor will probably want to talk to you about your weight loss goals and previous attempts to lose weight. If you are a generally appropriate candidate, he or she will move on to evaluate the suitability and safety of this medication in your specific case.

Some factors that the doctor may assess include:

  • Weight status
  • Vitals
  • Overall health
  • Medical history
  • Other medications & supplements

If phentermine is right for you, your doctor will discuss the benefits and risks of this medication and give you a script to fill at your preferred pharmacy.

3. Fill out the Prescription

After receiving a doctor’s prescription, you can buy phentermine at most major pharmacies in the US

In some cases, you can buy phentermine online by filling your prescription at a DEA-registered pharmacy and having the medication delivered in the mail ( 4 ).

However, this option is only available if the medicine is covered by insurance. Since phentermine is typically NOT covered by insurance, you will probably need to fill your prescription in-store (at least for the first month).

This rule is in place so that the pharmacy can check your ID and maintain compliance with DEA rules and regulations.

Some popular US pharmacies that offer services to fill a prescription online include:

  • CVS
  • Kaiser Permanente
  • Kroger
  • Walgreens
  • Walmart

Most pharmacies can fill your prescription same day if you walk into the store itself. Mail-order services typically take several days to a week.

4. Consider Online Refills

Some pharmacies offer online refill services so you can buy phentermine online in subsequent months

After you have filled your prescription in person for the first month, some pharmacies offer online refill services. Check with your preferred pharmacy to determine whether this is an option for you.

The only way to legally buy phentermine online is via a DEA-registered pharmacy, using a current and valid doctor’s prescription.

Note: Qsymia is only available via the Qsymia Home Delivery Network, which includes Walgreens, Walmart and Kaiser Permanente ( 5 ).

Cost of Phentermine

The cost of weight loss medication varies significantly depending on whether you purchase generic or brand-name pills, as well as your individual insurance coverage. It is also important to consider the additional cost of doctor visits, lab work, and other monitoring throughout the course of your treatment.

The table below shows the estimated costs for a 30-day supply of various phentermine pills:

How Can I Buy Cheap Phentermine?

Phentermine is a relatively affordable medication, even without insurance, but paying for weight loss pills each month can still add up. If you want to reduce the cost of your monthly phentermine prescription, consider these options:

  • Use insurance
    Most insurance companies do NOT cover prescription weight loss pills but discuss the possibility with your doctor. He or she may be able to prescribe a specific pill or brand that is covered by your insurance.
  • Request generic alternatives
    Generic phentermine is usually cheaper than brand name options, and most people feel it works the same. Ask your pharmacist about generic alternatives.
  • Look for coupons
    Pharmaceutical company websites will sometimes offer online coupons for the first month or similar. If you take brand-name phentermine (such as Lomaira or Qsymia), visit the medication’s website to find phentermine discounts.
  • Compare pharmacies
    Local pharmacies sell phentermine at slightly different prices, so you can save a little money by shopping around before you buy phentermine.

Why NOT Buy Phentermine Online

If you lack time, patience, or access to local doctors that prescribe phentermine, it may be tempting to buy phentermine online. However, this is not only illegal but also dangerous and expensive.

You should NEVER buy phentermine online without a prescription because:

It's illegal

It’s Illegal

It is illegal to buy or sell phentermine weight loss pills without a prescription. Given that the active ingredient is a class IV controlled substance, the unauthorized distribution or use of this medication is punishable by law.

Sites that claim to sell “real phentermine” without a prescription are either operating illegally or selling fake/counterfeit products. In most cases, it is also illegal to receive a prescription for this medication via telemedicine.

The easiest, safest, and most legal way to obtain phentermine is via a prescription from a local medical professional, which you can then fill at most major pharmacies.

Note that is is also illegal to order phentermine internationally as a US resident. Not only are you mailing controlled substances across international borders, but also receiving controlled substances in the mail from a facility this is not registered with the DEA. This is illegal.

It's dangerous

It’s Dangerous

Another very important reason to avoid buying phentermine online is the health risk. When you buy medications from illegal, online vendors, they are not subject to established regulatory processes, and you never know what’s in the “phentermine” pills that you purchase.

Online phentermine may be anything from foreign phentermine to dietary supplements to dangerous counterfeits that contain harmful chemicals. Losing weight should make you healthier, not sicker. Stay safe and get phentermine from a legitimate doctor and pharmacy, not a questionable site online.

Not convinced? Take this shocked user’s experience as a cautionary tale:

Many years ago I bought a bottle of “phentermine” from somewhere – maybe Canada? – and the first pill I took made me so sick. I did not take the rest, nor did I find a way to return the thing so I lost the money. Meanwhile, about a year later, I looked at the pills and, after starting-out white, they had become BROWN! I tossed them out and considered myself lucky I didn’t get REALLY sick from them.

It's fake

It’s Fake

Sites that advertise the sale of real phentermine without a prescription are likely advertising misleadingly and should be approached with care.

Remember, it is illegal to buy or sell real phentermine online, so some sites try to trick eager customers by offering fake “phentermine” online. They do not illegally sell or distribute controlled substances, but they do commonly mislead potential customers either directly or via omission of information.

Lots of sites online give info about the real phen but when you go to buy section its Phenxyz etc. Very misleading. Also one website that looked legit called it phenterimine. Unless you buy with online RX from a doc I would bet they all are caffeine/garcinia etc. It’s a controlled med so must have RX.

Sites that sell “phentermine from India” also have a particularly bad reputation for dispensing knockoff or counterfeit medicine. In fact, an astute consumer recently took to the Facebook support group to caution other users about sites that sell phentermine pills with the imprint K-25 from India. She pointed out that these “brand name” pills must be fake because the company that makes the real phentermine with the imprint K-25 is KVK Tech, and they are based in Pennsylvania.

Another user further supported this concern, noting:

I would be careful with meds coming from India. Phentermine isn’t even manufactured there.

Instead of buying discount phentermine online, see a doctor and buy real phentermine from a legitimate pharmacy.

It's a scam

It’s a Scam

Phentermine is not the cheapest medication, but it is definitely not the most expensive either. With generic phentermine tablets from the pharmacy starting at just nine dollars a month, this medication is within reach for most patients – even without insurance.

However, online pharmacies and malicious websites take advantage of people’s desperation to lose weight by charging significantly more for the same (or counterfeit) pills. As one flabbergasted potential customer recounted,

I came here to find another phentermine vendor and I CANNOT BELIEVE what one company charges $215 for a month?!?!? ARE YOU KIDDING? For a drug that without insurance you can buy at CVS for $30? That’s theft!!!

More, many of these online operations employ questionable payment and business practices. Some only accept cryptocurrencies (such as bitcoin) and offer no guarantee that you will receive your product, even after paying.

These unreliable sites shut down unexpectedly, share personal information and oftentimes fail to deliver the promised products. Engaging with these sorts of untraceable sites is both risky and unreliable.

To safeguard against fraudulent transactions with any online merchant, guard your personal information closely and NEVER order from a business without a physical address and phone number.

Our Recommendation

Do NOT buy phentermine online. It’s illegal, dangerous, and often fake or a scam.

Phentermine is a prescription medication for a reason. The active ingredient, phentermine HCL, is a controlled substance because it is powerful and potentially addictive.

Even though it may be tempting to buy phentermine online, it is critical that a medical professional evaluate your current health and other medications before starting this medication. This evaluation should ALWAYS be completed in person and not via telemedicine.

If you are a good candidate for prescription weight loss drugs, there are many practitioners and weight loss clinics that will write a prescription to help you reach your weight loss goals. Do NOT buy phentermine online.

It’s illegal. It’s fake. It’s not regulated. And it’s dangerous.

Is ordering phentermine from Mexico legal and safe?

No, and no. Numerous sites sell phentermine from Mexico, claiming that it will be delivered to your US address in a “discreet” package. Most of these sites are based in India, some in Mexico, and others in China, or other countries. Do NOT buy phentermine online from these sites. In addition to the fact that ordering online without a prescription is illegal, you also run the risk of receiving:

  • Fake or counterfeit pills
  • Dangerous medications or supplements that make you sick
  • Nothing at all (and losing your money)

Instead, make an appointment with your doctor and talk to him/her about your desire to lose weight so that the two of you can discuss appropriate options, perhaps including phentermine.

Is it possible to buy Elvenir or Sentis online?

If you are a US resident, it is NOT legal to buy Elevenir or Sentis online. These medications are not sold in the United States and, as such, cannot be received/taken legally in the US. If you live in Chile or another country where these brands are registered and sold, you can request a prescription for these specific brands of phentermine.

Can I buy phentermine online in Australia?

No. The Convention on Psychotropic Substances classifies phentermine as Schedule IV controlled substance internationally, including in Australia ( 6). As a result, sales and distribution of the medication are continuously monitored by authorities. So, similar to the United States, the only way to buy phentermine in Australia is from a registered pharmacy, using a valid doctor’s prescription.
