There are now three generic Epivir (lamivudine) products available. The FDA has assigned an "AB" rating to these products, which means that they are considered equivalent to the brand-name version. However, generic Epivir is allowed to have different inactive ingredients (such as fillers or dyes), which may cause problems for people with certain allergies or sensitivities.
Epivir® (lamivudine) is a prescription antiviral medication. It is part of a group of medications known as nucleoside reverse transcriptase inhibitors (also known as NRTIs). Epivir is approved to treat the following viral infections:
Epivir comes in two forms, regular Epivir (approved to treat HIV and AIDS) and Epivir-HBV (approved to treat hepatitis B). There is no real difference between Epivir and Epivir-HBV products, except that they come in different strengths.
Brand-name Epivir is made by GlaxoSmithKline. Some Epivir products (but not all of them) are available in generic form.
- Lamivudine 100 mg tablets
- Lamivudine 150 mg tablets
- Lamivudine 300 mg tablets.
The oral solutions (the 5 mg per mL and the 10 mg per mL strengths) are not yet available in generic form.
Generic Epivir is made by various manufacturers, such as:
- Apotex Corporation
- Aurobindo Pharma Limited.
All generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns a rating to each one.
An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic versions of Epivir currently available have an "AB" rating, meaning they should be equivalent to Epivir.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
