Phentermine Phentermine 37.5 mg x 20 tabs

DOSING: The recommended dose is 30 mg once daily about 2 hours after breakfast. Evening doses should be avoided because phentermine causes insomnia. DRUG INTERACTIONS: Phentermine is similar to amphetamine and may share some of the interactions associated with amphetamines. Combining phentermine with tricyclic antidepressants [for example, amitriptyline (Elavil, Endep)] or monoamine oxidase inhibitors (for example, tranylcypromine) may result in high blood pressure and other serious reactions because of elevated serotonin levels in the blood. PREGNANCY: Use of phentermine during pregnancy has not been adequately evaluated. NURSING MOTHERS: It is not known whether phentermine is excreted in human breast milk. SIDE EFFECTS: Side effects of phentermine include nausea, vomiting, diarrhea, dry mouth, constipation, an unpleasant taste, hives, impotence, palpitations, high blood pressure, and fast heart rates (palpitations). Central nervous system side effects include hyperactivity, insomnia, restlessness, tremor, and dizziness. Phentermine, especially when combined with fenfluramine, has been associated with high pressures in the pulmonary arteries (pulmonary hypertension) and defects in heart valves, both serious complications. Physical and psychological dependence may occur with the long-term use of phentermine. A withdrawal reaction, which includes excessive drowsiness, fatigue, tremors and depression may occur after prolonged use.
