No, buying phentermine over the counter is not possible as it is a class IV controlled substance. Branded versions of phentermine, including Adipex-P, are also subject to the same prescribing rules of the Controlled Substances Act (CSA). The Controlled Substances Act is regulated by the United States Drug Enforcement Administration. Its role is to determine how medications should be accessed based on the likelihood of addiction, dependence, or abuse ( 1 ). As phentermine has a similar chemical structure to amphetamines, there is a risk of dependence. For this reason, in most cases, phentermine is only prescribed for three months at a time. Phentermine can also cause a range of common and serious side effects, such as headaches, dry mouth, mood changes, and hallucinations. It is, therefore, not considered safe to buy phentermine or Adipex over the counter ( 2 ). Related: Side Effects of Phentermine Prescription Phentermine vs. Over-the-Counter Alternatives The good news is many over-the-counter phentermine alternatives do not require you to consult a doctor for a prescription. However, there are differences between prescription phentermine and over-the-counter diet pills. Key Differences Unlike phentermine, over-the-counter diet pills can be purchased without a prescription from CVS, Walgreens, and even Amazon, making them a convenient choice. There’s no need to speak to a doctor or pharmacist; you can often have the pills delivered to your door whenever you need them. ALTERNATIVE Buy Phen Now! No Prescription Required. No Side Effects. Made in USA. Get 20% off now! Whereas Adipex-P has a long list of irritating, and in some cases, serious, side effects, over-the-counter equivalents to phentermine may have no side effects at all. For this reason, if you find that an OTC weight loss pill is helpful, you may be able to take it long-term rather than being limited to three months as with phentermine ( 3 ). Compared to phentermine, over-the-counter diet pills can help you lose a similar amount of weight. Using natural ingredients, weight loss supplements promote fat burning while reducing the appetite and boosting energy levels. Unlike phentermine, weight loss is achieved without the risk of side effects or the potential for addiction ( 4 ). Who Should Consider OTC Alternatives? You may consult a doctor and find that, based on your weight and medical background, they are willing to prescribe phentermine for you. However, many people eligible for a phentermine prescription choose to take an alternative instead. For example, you may prefer to try an over-the-counter diet pill to focus on losing weight without worrying about serious side effects or the potential for addiction. Some people cannot take phentermine because they have conditions including heart disease, high blood pressure, diabetes, or a history of addiction. In this case, an over-the-counter equivalent to phentermine may be recommended. Alternative weight loss pills can help reduce the appetite and burn calories without putting your health at risk.

Despite containing natural ingredients, diet pills are often contraindicated for individuals under 18, and pregnant or breastfeeding women. If you have a medical condition or take any other prescribed, over-the-counter or herbal medications, you should speak to your doctor or pharmacist to check that the diet pill will suit you. Taking over-the-counter phentermine alternatives can be safer than taking phentermine. Still, it is important to remember that, unlike phentermine, supplements are not monitored by a doctor. If you have concerns, you should consult a trained healthcare professional. The final consideration is that while many diet pills have shown promise in clinical trials, the best weight loss outcomes are always achieved when supplements are taken in conjunction with a calorie-controlled diet and increased physical activity. It is therefore essential to also make lifestyle changes. Conclusion It is not possible to buy phentermine over the counter. Still, you can purchase various alternative weight loss supplements without a prescription. Natural supplements can suppress the appetite and boost fat burning for increased weight loss without the severe side effects of phentermine. FAQs Where can you get phentermine over the counter?
