Phentermine is a prescription medication used for short-term weight management. It is a sympathomimetic amine that acts to suppress appetite and promotes weight loss by acting on the central nervous system.

Phentermine stimulates the release of certain neurotransmitters, such as norepinephrine, in the brain. By doing so, it suppresses appetite, increases feelings of satiety, and elevates energy expenditure. This combination can assist individuals in adopting a healthy diet and engaging in regular physical activity, leading to weight loss.

As a controlled substance, the use and distribution of phentermine are regulated to ensure safe and appropriate prescribing practices. In this article, we will guide you through the steps on how to get a phentermine prescription online. You will also know how to ask a doctor to prescribe phentermine online. We will help you take a confident step toward your weight loss goals while leveraging the convenience of telehealth.

What Are the Requirements to Get Phentermine Prescription?

Phentermine is an FDA-approved weight loss medicine classified as a Schedule IV controlled substance. It means that it has some potential for abuse and dependence. That is why this medication is not available over the counter and you have to get phentermine prescribed by a licensed doctor.

The requirements for getting a phentermine prescription online from a doctor are the following:

  1. Medical evaluation. Before prescribing phentermine, registered healthcare providers conduct a thorough medical evaluation. It may include a review of the patient’s medical history, physical examination report, and assessment of current health conditions. This step is crucial to identify any contraindications or potential risks associated with the medication.
  2. Body mass index (BMI). Phentermine is generally recommended for individuals with a body mass index of 30 or higher. In some cases, individuals with a BMI of 27 or higher may qualify for phentermine if they have weight-related health conditions like diabetes, high blood pressure, or high cholesterol. (The BMI calculation is based on an individual’s height and weight.)
  3. Weight loss efforts. Healthcare providers often require individuals to have made sincere attempts to lose weight through lifestyle modifications before considering phentermine. These efforts may include dietary changes, increased physical activity, and other non-pharmacological approaches. Demonstrating a commitment to weight loss and the need for additional support can strengthen the case for a phentermine prescription.
  4. Regular monitoring. Once prescribed phentermine, patients are typically required to have regular check-ups with their healthcare providers. This allows for monitoring of the medication’s effectiveness, potential side effects, and overall progress in achieving weight loss goals. These appointments also provide an opportunity to adjust the dosage or consider alternative treatment options if necessary.
  5. Contraindications and precautions. Phentermine is not suitable for everyone. Pregnancy and breastfeeding, as well as certain medical conditions, such as heart disease, high blood pressure, hyperthyroidism, glaucoma, and a history of drug abuse, may contraindicate the use of this medicine. Moreover, individuals with a history of lung conditions and mental health disorders require additional caution when considering phentermine. In patients with renal impairment dosage adjustment of phentermine may be necessary. Diabetic patients taking insulin or oral hypoglycemic medications may need to modify their dosages. It is important to disclose all relevant medical information to the healthcare provider to ensure safe and appropriate use.

Note that phentermine should only be used under the supervision of a doctor for a limited duration, usually up to 12 weeks [1*] . Following the prescribed dosage guidelines is essential to minimize the potential for side effects and reduce the risk of dependence and abuse.

Who Can Prescribe Phentermine?

Its prescription authority extends to various registered healthcare professionals, including:

  • Family doctors and primary care physicians. Often, they are the first point of contact for patients seeking medical advice and treatment. Family doctors have the authority to prescribe phentermine if they determine it is appropriate for a patient’s weight management needs. They can evaluate a patient’s medical history, conduct physical examinations, and make informed decisions about prescribing phentermine based on their clinical judgment.
  • Bariatric doctors, also known as weight loss doctors or obesity medicine specialists, specialize in the medical management of weight-related issues. These doctors have specific expertise in addressing the complex factors contributing to weight gain and can prescribe medications like phentermine as part of a comprehensive weight loss program. Weight loss doctors are trained to assess a patient’s overall health, evaluate underlying medical conditions, and design personalized treatment plans that may include medications, dietary interventions, behavior modification, and exercise regimens.
  • Other specialists in weight loss clinics often comprise a multidisciplinary team of healthcare professionals, such as doctors, nurse practitioners, physician assistants, and registered dietitians. These practitioners are dedicated to helping individuals achieve their weight loss goals and can prescribe medications when required.

  • Release of norepinephrine [2*] reduces appetite and hunger helping individuals consume fewer calories and support weight loss.
  • Boosting dopamine and norepinephrine levels collectively increases energy and alertness. This can motivate individuals to engage in physical activity and maintain an active lifestyle.
  • Indirectly affecting serotonin levels leads to feelings of fullness and satisfaction after eating, while also enhancing mood and well-being in some individuals.

However, the exact mechanisms of phentermine are not fully understood, and responses can vary. Healthcare professionals should closely monitor the medication's impact on appetite, energy, and mood during treatment.
