Tecavir 0.5mg Tablet 1 Strip

✔️ Administration

Administer orally on an empty stomach, at least two hours after a meal and two hours before the next meal. Dose adjustments may be necessary in patients with renal impairment. An oral solution may be useful when smaller doses are required.

Adult Dose

• For chronic hepatitis B in adults and adolescents aged 16 years or older, the usual dose is:
• Nucleoside-naïve patients with compensated liver disease: 0.5 mg once daily.
• Patients with lamivudine-refractory disease or known lamivudine/telbivudine resistance: 1 mg once daily.
• Patients with decompensated liver disease: 1 mg once daily.
• The appropriate dose depends on treatment history, liver status, renal function, and the prescribing clinician's assessment.

Pediatric Dose

Entecavir may be indicated for children aged two years or older who weigh at least 10 kg, depending on treatment history and formulation. The dose is weight-based and must be determined by a specialist. Safety and efficacy have not been established in children younger than two years. Adolescents aged 16 years or older generally follow adult dosing recommendations when appropriate.

Renal Dose

Entecavir is primarily eliminated through the kidneys. Dose adjustment is required when creatinine clearance is below 50 mL/min.

• For the usual 0.5 mg regimen, the reference dose adjustments are:
• CrCl 50 mL/min or higher: No adjustment generally required.
• CrCl 30–49 mL/min: 0.25 mg once daily or 0.5 mg every 48 hours.
• CrCl 10–29 mL/min: 0.15 mg once daily or 0.5 mg every 72 hours.
• CrCl below 10 mL/min, hemodialysis, or CAPD: 0.05 mg once daily or 0.5 mg every seven days.

Patients requiring the 1 mg regimen need different adjustments. The exact regimen must be selected by the treating clinician, with consideration of dialysis timing and the available formulation.

✔️ Entecavir Uses

• Treatment of chronic hepatitis B virus (HBV) infection in eligible patients.
• Reduction of hepatitis B viral replication.
• Management of chronic HBV infection to help reduce the risk of progressive liver damage.

✔️ Side Effects:

Common adverse effects include headache, fatigue, dizziness, and nausea. Less frequently, patients may experience diarrhea, vomiting, indigestion, insomnia, or drowsiness. Rare serious effects include lactic acidosis and severe liver complications.

✔️ Interaction

Medicines that affect kidney function or compete for active tubular secretion may increase the blood concentrations of entecavir or the co-administered medicine. Inform your doctor about all medicines you take, particularly those that may affect renal function.

✔️ Pregnancy & Lactation

Available data are insufficient to fully assess the risks of entecavir during pregnancy. The decision to use it should be based on specialist assessment of the mother's condition and available treatment alternatives.

It is not known whether entecavir passes into human breast milk or affects milk production or the breastfed infant. Breastfeeding decisions should be discussed with the treating clinician, considering the mother's need for treatment and the potential risks to the infant.

✔️ Contraindications

Tecavir is contraindicated in patients with known hypersensitivity to entecavir or any ingredient in the formulation.

✔️ Safety Information:

• Lactic acidosis: Rare cases of lactic acidosis and severe hepatomegaly with steatosis have been reported with nucleoside analogues.
• Hepatitis flare after discontinuation: Stopping treatment may cause an acute exacerbation of hepatitis B. Close clinical and laboratory monitoring is necessary after discontinuation.
• Renal impairment: Dose adjustment is necessary in patients with reduced kidney function.
• HIV coinfection: Patients with HIV and HBV coinfection require an appropriate, fully suppressive HIV treatment regimen. Entecavir should not be used as a substitute for combination HIV therapy.
• Pregnancy and breastfeeding: Discuss treatment with a specialist because available pregnancy data are limited and the presence of entecavir in human breast milk is unknown.

✔️ Storage:

Store in a dry place away from light and heat. Keep out of the reach of children.
