Famciclovir 750 mg Tablet

Adult dose

1. Treatment of herpes zoster Adults: Administer 750 mg of famciclovir orally once daily for 7 days. Take it at the same time each day. It is advisable to start treatment as soon as symptoms appear after infection. 2. Patients with renal impairment: Because the creatinine clearance of this medicine is reduced in patients with renal impairment, dose adjustment should be performed with caution. The dosage and administration for these patients are as follows. 1) Treatment of herpes zoster Creatinine clearance (mL/min/1.73㎡) 30～59: 250 mg per dose twice daily 10～29: 250 mg per dose once daily 2) If only the serum creatinine level is known, creatinine clearance can be calculated using the following formulas. Men: {body weight (kg) × (140-age)}/ {72 × serum creatinine (mg/dL)} Women: 0.85 × the value calculated for men 3) Patients with renal impairment undergoing hemodialysis: In patients on hemodialysis, administration every 48 hours is advisable, taking the dialysis interval into account. Four hours of hemodialysis reduces the plasma concentration of this medicine by approximately 75%; therefore, administer the full dose of this medicine immediately after dialysis. 3. Patients with hepatic impairment: No dose adjustment is required in patients with chronic compensated liver disease. There is insufficient treatment experience in patients with overt chronic decompensated liver disease; therefore, no clear recommended dose has been established.

This medication should not be used by patients with allergies to specific ingredients. Patients with impaired kidney function should take this medication cautiously and may need to adjust the dosage according to their doctor's directions. During treatment, symptoms such as headache, dizziness, nausea, vomiting, and skin rash may occur, so if any unusual symptoms appear, immediately consult a healthcare professional. This medication does not cure genital herpes, and it is important to avoid sexual contact and maintain safe sexual practices if symptoms persist during treatment. If symptoms such as dizziness or drowsiness occur, driving or operating machinery should be avoided. Patients with slightly impaired liver function do not require special dosage adjustments, but patients with severe liver disease may experience reduced effectiveness of this medication. This medication may interact with other drugs, so if you are taking other medications, be sure to inform your doctor or pharmacist. Women who are pregnant or may become pregnant should carefully consider the benefits and risks of using this medication, and the same applies to breastfeeding women. Children under 18 years of age are not recommended to use this medication as its safety and effectiveness have not been established. Elderly patients generally do not require dosage adjustments, but in cases of reduced kidney function, adjustments may be necessary.
