Phenamine Tablets (Phentermine Hydrochloride)

Adult dose

Adults: Administer 37.5 mg of phentermine hydrochloride orally once daily before breakfast or 1 to 2 hours after breakfast. Use the minimum effective dose, adjusting it individually to achieve an adequate response. A dose of 18.75 mg once daily may be appropriate for some patients, and in some cases, 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 improper use of this medicine, treatment 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 conjunction with other appetite suppressants, and should only be taken alone for a short period of time. The combination with other medications aimed at weight loss is not recommended as safety and efficacy have not been established. This medication may be associated with primary pulmonary hypertension; therefore, if symptoms such as shortness of breath, chest pain, fainting, or leg swelling occur, the patient should immediately inform a doctor. It may also be related to valvular heart disease, but it is rarely reported when used alone. People with certain conditions such as advanced atherosclerosis, cardiovascular diseases, moderate to severe hypertension, pulmonary hypertension, and hyperthyroidism should not take this medication. Furthermore, individuals with hypersensitivity to this medication, those sensitive to sympathomimetic amines, glaucoma patients, individuals with mental agitation or excitement, and those with a history of substance abuse should avoid taking it. Women who are pregnant or may become pregnant, children under 16, and those with certain genetic lactose intolerance should also refrain from using this medication. Diabetic patients or those with mild hypertension should use it cautiously, and diabetic patients may require insulin dosage adjustments. Overdose may result in severe central nervous system and cardiovascular symptoms, so strict adherence to the dosage is essential. This medication can cause psychological dependence, and abrupt cessation after prolonged high-dose use may result in fatigue and depression. Care should be taken when performing risky activities such as operating machinery or driving. Taking this medication with alcohol may increase the risk of side effects, so it should be avoided. Pregnant or nursing women should use this medication only when absolutely necessary, under a doctor's supervision, as it may pose risks to the fetus or infant. This medication should be kept out of reach of children and is classified as a controlled substance, so caution against abuse is necessary.
