Adovir- 10 mg Tablet/pcs

The most common side effects of adefovir dipivoxil are weakness, headache, stomach pain and nausea. Severe acute exacerbations of hepatitis have been reported in patients who have discontinued anti-hepatitis B therapy, including therapy with adefovir dipivoxil. In patients at risk of or having underlying renal dysfunction, chronic administration of adefovir dipivoxil may result in nephrotoxicity. Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs alone or in combination with other antiretrovirals.

Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Adefovir dipivoxil should be used during pregnancy only if clearly needed and after careful consideration of the risks and benefits. It is not known whether adefovir is excreted in human milk. Mothers should be instructed not to breast-feed if they are taking adefovir dipivoxil.

Patients who discontinued adefovir dipivoxil should be monitored at repeated intervals over a period of time for hepatic function. The patients at risk of or having underlying renal dysfunction should be monitored closely for renal function and may require dose adjustment.

Pediatric use: Safety and effectiveness in pediatric patients have not been established.

Geriatric use: In general, caution should be exercised when prescribing to elderly patients since they have greater frequency of decreased renal or cardiac function due to concomitant disease or other drug therapy.

Dose Adjustment in Renal Impairment: the dosing interval of Adefovir should be adjusted in patients with baseline creatinine clearance <50 ml/min using the following suggested guidelines:

• CrCl ≤ 50 ml/min: 10 mg
• CrCl 20-49 ml/min: 10 mg every 48 hours
• CrCl 10-19 ml/min: 10 mg every 72 hours
• Haemodialysis patients: 10 mg every 7 days following dialysis

Doses of adefovir dipivoxil 500 mg daily for 2 weeks and 250 mg daily for 12 weeks have been associated with gastrointestinal side effects. If overdose occurs the patient must be monitored for evidence of toxicity and standard supportive treatment applied as necessary.
