Sebivo

Introduction
Sebivo is used in the treatment of HIV infection and chronic hepatitis B virus (HBV) infection. It prevents the multiplication of virus in human cells. This stops the virus from producing new viruses and clears up your infection. Sebivo is prescribed in combination with other HIV medicines. Your doctor will recommend the best medicines for you and will decide the doses that you need. Follow carefully the instructions for all the medicines that you are given. It can be taken with or without food. Taking all these medicines regularly at the right times greatly increases their effectiveness and reduces the chances of HIV becoming resistant to them. It is important not to miss doses and to keep taking them until your doctor tells you it is safe to stop. Common side effects of this medicine include nausea, stomach pain, weakness and headache. These are usually not serious but tell your doctor if they bother you or do not go away. Rarely, some people may experience a skin reaction or liver damage. Your doctor will closely monitor you for these in the initial period of treatment. Before taking it, tell your doctor if you have any skin problems or liver or kidney disease. While using it, you may need regular blood tests to check your blood counts and liver function. Avoid drinking alcohol as it may increase your risk of liver damage. Pregnant or breastfeeding mothers should consult their doctor before using this medicine. Do not have unprotected sex or share personal items like razors or toothbrushes, if you are HIV positive. Talk to your doctor about safe ways like condoms to prevent HIV transmission during sex.

Renal Dose
Renal impairment: ESRD: 600 mg 96 hrly, after dialysis session. CrCl (ml/min) Dosage Recommendation <30 (not requiring dialysis) 600 mg 72 hrly. 30-49 600 mg 48 hrly. _ Contraindication Hypersensitivity. Lactation. Concurrent use w/ peginterferon alfa-2a.

It is used in the treatment of chronic hepatitis B infection. Precaution Patient w/ cirrhosis, hepatomegaly or other risk factors for liver disease. Renal impairment. Pregnancy. Monitoring Parameters Monitor hepatic function (e.g. AST and ALT) periodically during therapy and for several mth following discontinuation of therapy; renal function; signs and symptoms of peripheral neuropathy or myopathy; serum creatine kinase; hepatitis B virus (HBV) DNA 3-6 mthly during therapy; HBeAg and anti-HBe signs/symptoms of HBV relapse/exacerbation after discontinuation of therapy.
