Phedin (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 the dose individually to achieve an adequate response. A dose of 18.75 mg once daily may be appropriate for some patients, while in some cases it may be preferable to take 18.75 mg twice daily. Avoid taking this medicine late at night because it may cause insomnia. This medicine should be administered for a short term (within 4 weeks). However, to reduce the risk of inappropriate use, treatment may be continued if the patient achieves satisfactory weight loss within the first 4 weeks (at least 1.8 kg of weight loss, or weight loss considered satisfactory by both the physician and patient).

This medication should not be used in conjunction with other appetite suppressants. It must be used alone for short-term management of exogenous obesity, and combining it with other weight loss drugs may not guarantee safety and effectiveness. This medication may be associated with primary pulmonary hypertension, so if symptoms such as dyspnea, angina, syncope, or peripheral edema occur, the patient should inform their doctor immediately, and the medication should be discontinued if these symptoms arise. There may also be potential associations with valvular heart disease, so long-term use, exceeding recommended dosages, or taking it with other appetite suppressants should be avoided. This medication should not be administered to patients with specific conditions, such as severe atherosclerosis, cardiovascular disease, moderate to severe hypertension, pulmonary hypertension, hyperthyroidism, glaucoma, mental instability, or a history of substance abuse. Additionally, patients taking MAO inhibitors, those who have taken them within the past 14 days, children under 16 years of age, and pregnant women or women who may become pregnant should not use this medication. Patients with diabetes or mild hypertension should use this medication cautiously, and diabetic patients may require adjustments to their insulin doses. This medication can cause various side effects such as palpitations, anxiety, headache, dizziness, dry mouth, diarrhea, constipation, hives, and erectile dysfunction, so if symptoms occur, consultation with a physician is necessary. In case of overdose, severe symptoms such as anxiety, coma, tremors, respiratory distress, abnormal blood pressure, or vomiting may occur, requiring immediate emergency treatment. This medication may cause dangerous interactions when taken with alcohol, so they should not be taken together. Pregnant or nursing women should only use this medication if absolutely necessary, considering the potential effects on the fetus and infant, and it is not recommended for children under 16 years of age due to a lack of proven safety and effectiveness. This medication is classified as a controlled substance with potential for dependency and abuse, so strict adherence to the physician's instructions is essential, and sudden discontinuation after prolonged use at high doses may lead to fatigue and depression. Finally, this medication should be stored in a secure place out of reach of children.
