Phentermine is a prescription-only weight loss drug that helps patients lose weight by suppressing appetite and boosting energy. This medication was first approved by the FDA in 1959  and has remained a popular option for pharmaceutical obesity management ever since.
It used to be possible to buy phentermine online, but the distribution of weight loss medications has become strictly controlled in recent years. As a result, phentermine is no longer available for purchase online without a valid prescription. This is both to protect the consumer (patient) and deter the sale of counterfeit medications.

Phentermine hydrochloride (a.k.a. phentermine HCl), the active ingredient in phentermine weight loss pills, is classified as a class IV controlled substance in the United States and abroad . As a result, the Ryan Haight Online Pharmacy Consumer Protection Act of 2008 made it illegal to buy phentermine online without attending an in-person doctor’s visit first .
Due to the active ingredient’s DEA classification, as well as the Ryan Haight Act, phentermine is NOT sold online and the distribution and use of this medication is closely monitored by federal authorities.
Most other prescription weight loss drugs also contain a controlled substance as their active ingredient, so prescription diet pills in general are not sold online. If you find a site claiming to sell phentermine or any other weight loss medication online without a prescription, they are likely operating illegally and/or based outside of the United States. Approach these sites with extreme caution.
If you already have a valid prescription, it is possible to buy phentermine online through some pharmacies. Below you will find a breakdown of how and where to purchase phentermine online, as well as the approximate cost for a one-month supply of medication.
You can buy phentermine online by registering your prescription at a legitimate pharmacy and having the medication delivered in the mail.
It is still legal to receive prescription medications by mail as long as they are mailed from a DEA-registered pharmacy . Therefore, if you have a valid prescription from your doctor, you can fill the script online and pay for mail delivery. This is the only way to order phentermine online legally.
The best place to buy phentermine online is a legitimate, verifiable pharmacy. Conveniently, most major pharmacy chains offer reliable online fulfillment programs. Some popular US pharmacies that offer services to fill a prescription online include:
You can register your prescription by visiting your preferred pharmacy’s individual site and providing the required information.
Do NOT order from sites that claim to offer phentermine (or any other prescription weight loss pill) without a prescription or via telemedicine. Recent reports estimate that there are over 3300 online pharmacies operating in violation of current laws, which may be selling controlled substances illegally and/or peddling counterfeit medication .

Even though it’s no longer legal to buy phentermine online, you may still see the medication advertised.
Sites that advertise the sale of real phentermine without a prescription are engaged in misleading advertising and should be approached with care. If you find phentermine for sale online without a prescription, the site is likely operating illegally and/or based outside of the United States.
For example, when ordering online, it is easy to misread phentREmine or phentARmine, thinking that they are true phentERmine. These differently-spelled products are not phentermine and do not contain phentermine as an ingredient. Sites that sell “phentermine from India” also have a particularly bad reputation for dispensing knockoff or counterfeit medicine. Instead of being tempted to buy phentermine online cheap, see a doctor and buy real phentermine from a legitimate pharmacy.
Because Phentermine is a prescription drug, you can't buy it on Amazon. When searching for 'phentermine' on Amazon, the results displayed are weight loss supplements which do not contain the active ingredient Phentermine HCl. This is confusing and Amazon should clearly state that they don't sell Phentermine. But this is not the case.
When searching on the internet, you will find many sites claiming that they sell Phentermine that will be delivered to you in a 'discrete' package. Most of these sites are based in India, some in Mexico, others in China. Our advice is to never buy from these sites:
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.
