## Primary Indications
* Hepatitis B (chronic)
* Hepatitis C (chronic), in combination therapy.
## Adult Dosing
* **Chronic Hepatitis B:** The typical dose is 300 mg once daily.
* **Chronic Hepatitis C:** Dosing varies significantly based on the specific regimen, duration, and presence of cirrhosis. A common regimen involves 300 mg once daily in combination with other direct-acting antivirals. Consult specific treatment guidelines for recommended combinations and durations.
## Pediatric Dosing
Data for pediatric use is limited. Dosing should be determined by a specialist based on age, weight, and clinical status.
## Dose Adjustments
* **Renal Impairment:** Dose adjustment is required in patients with moderate to severe renal impairment.
* CrCl 30-49 mL/min: 300 mg every 48 hours.
* CrCl < 30 mL/min (including dialysis): 300 mg every 72 hours or 300 mg once weekly on dialysis days.
* **Hepatic Impairment:** No dose adjustment is typically needed for mild to moderate hepatic impairment. Data in severe hepatic impairment is limited.
## Contraindications
* Hypersensitivity to the active ingredient or any excipients.
## Adverse Effects
Common adverse effects include fatigue, headache, nausea, diarrhea, insomnia, and rash.
## Key Drug Interactions
* **Strong CYP3A4 Inducers:** Concurrent use with strong CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin, St. John's wort) can significantly decrease plasma concentrations of Tab%2525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520voihep, potentially leading to loss of efficacy. Avoid concurrent use.
* **Other Antivirals:** Numerous drug interactions can occur when used in combination therapy for Hepatitis C. Review all concomitant antiviral agents for potential interactions.
## Monitoring
* **Hepatitis B:** Monitor viral load (HBV DNA), ALT levels, and liver function tests.
* **Hepatitis C:** Monitor viral load (HCV RNA), ALT levels, and liver function tests as per specific treatment regimen guidelines.
* **Renal Function:** Monitor periodically, especially in patients with pre-existing renal impairment or those taking other nephrotoxic drugs.
## Clinical Pearls
* Ensure adequate contraception for both male and female patients of reproductive potential due to potential risks during pregnancy.
* In combination therapy for Hepatitis C, adherence is crucial for achieving sustained virologic response.
