Metamax Tablet (Phentermine Hydrochloride)

Adult dose

Adults: Administer 37.5 mg of phentermine hydrochloride orally once daily, before breakfast or 1–2 hours after breakfast. Use the lowest effective dose, adjusting it individually to achieve an adequate response. A dose of 18.75 mg once daily may be appropriate for some patients, while in some cases, taking 18.75 mg twice daily may be preferable. Avoid taking this medicine late at night because it may cause insomnia. This medicine should be administered for a short period (within 4 weeks). However, to reduce the risk of inappropriate use, treatment with this medicine may be continued if the patient achieves satisfactory weight loss within the first 4 weeks (weight loss of at least 1.8 kg, or weight loss considered satisfactory by both the physician and the patient).

This medication should not be used in combination with other appetite suppressants and should only be used alone for a short period. Combining this medication with other weight loss drugs is not recommended, as safety and efficacy are not assured. This medication may be associated with primary pulmonary hypertension, so symptoms such as dyspnea, chest pain, syncope, and leg swelling should be reported to a physician immediately.

Individuals with advanced atherosclerosis, cardiovascular disease, severe hypertension, pulmonary hypertension, hyperthyroidism, glaucoma, severe anxiety disorders, or a history of drug abuse should not take this medication. Furthermore, it should not be administered to children under the age of 16 or to pregnant or potentially pregnant women.
