Pentain 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 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, 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 (no more than 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 judged satisfactory by both the physician and the patient).

This medication should not be used in conjunction with other appetite suppressants. It should only be used as a short-term treatment for exogenous obesity, and the safety and efficacy have not been confirmed when used in combination with other weight loss drugs. Patients should immediately inform their physician if symptoms such as dyspnea, chest pain, fainting, or leg swelling occur while taking this medication, and discontinuation of the medication should follow if such symptoms occur. There may be a risk associated with heart valve disorders, but cases reported with monotherapy are few. Patients with advanced atherosclerosis, cardiovascular diseases, severe hypertension, pulmonary hypertension, hyperthyroidism, glaucoma, those who are mentally anxious or agitated, individuals with a history of substance abuse, children under 16 years of age, and women who are pregnant or may become pregnant should not take this medication. Diabetic patients or those with mild hypertension must take this drug with caution, and diabetic patients may need insulin dosage adjustments. Overdose may lead to severe symptoms such as anxiety, coma, tremors, hallucinations, arrhythmia, abnormal blood pressure, and vomiting, so caution is advised. This medication can affect the central nervous system, resulting in side effects such as insomnia, anxiety, and dizziness, and care is needed when driving or operating hazardous machinery. Taking it with alcohol can exacerbate side effects, so it should be avoided. Pregnant or breastfeeding women should strictly consult with a doctor before use as it may pose risks to the fetus and infant. This medication is classified as a narcotic, with the potential for dependence and abuse, so it should be used strictly according to a physician's prescription and instructions. It should be stored out of reach of children, and sudden discontinuation after prolonged high-dose use may lead to fatigue and depression, so caution is necessary.
