Dosage of Phentermine appetite suppressant is adjusted for every patient individually. The dose choice depends on a patient’s age, obesity degree, history of heart attack or stroke and current comorbidities.

Phentermine and its generic drugs are manufactured by different pharmacological companies. Mostly, Phentermine is found in weight loss pills in salt form or as ion exchange resins.

For instance, Adipex tablets contain 37.5mg of Phentermine in salt form. Adipex 37.5mg is equal to 30mg of Phentermine base. You can divide the tablet into 2 equal parts (15mg of Phentermine base) if needed.

Duromine capsules contain Phentermine as ion exchange resins. Duromine capsules are equal to 15, 30 or 40 of Phentermine base. Maximum dose of Phentermine 40mg is allowed in a few countries. For example, Phentermine 40mg is used in Australia, but is not used for anti-obesity therapy in the USA and New Zealand.

The recommended dose is Phentermine 30mg per day. In the beginning of anti-obesity therapy, a minimal dose of the drug (15mg) can be used per day. This allows a patient to evaluate the body reaction, adjust the dose and avoid side effects.

For most obese patients, the recommended dosage of Phentermine is 30mg per day. Peroral dose of 30mg is prescribed for patients, who do not have:

  • Significant heart problems
  • The central nervous system disease

Maximum dose Phentermine 40mg a day is prescribed to patients for whom 30mg dose does not provide a sufficient appetite suppression. When using the maximum dosage, a patient must be careful and check his heart rate and the blood pressure level regularly.

Minimal dose of Phentermine 15mg can be ineffective for most overweight patients. Most often Phentermine 15mg daily dose is prescribed to people over 65 years old, young people between 12 and 18 years (Australia) and to patients with some disorders and pathologies.

You can buy the CNS stimulant Phentermine in form of capsules or tablets with different dosage. Please keep in mind that overdosage on this drug can be dangerous. Do not take more than two Phentermine pills a day.
