Common Use

Epivir is an antiviral medication used to combat infections caused by the human immunodeficiency virus (HIV), which is the primary cause of AIDS. It works by preventing the cells from producing new viruses and reducing the viral load in the body. Additionally, Epivir is prescribed for the treatment of chronic hepatitis B infection. It is important to note that this medication must be used in combination with other HIV drugs for optimal effectiveness.

Dosage and Direction

Take Epivir orally with or without food or milk, at the same time each day. For adults, the standard dose for hepatitis B treatment is one 100mg tablet once daily. For HIV treatment, the recommended dosage is one 300mg tablet once daily or one 150mg tablet every 12 hours.

For children, the dosage is determined by the child's weight and their ability to swallow pills. The liquid formulation should be administered at 4 mg per kilogram of body weight, up to a maximum of 150 milligrams twice daily.
