AIDS Home > Generic Trizivir

Despite the fact that the first three patents for Trizivir have expired, there are currently no generic Trizivir products available in the United States. It is difficult -- if not impossible -- to predict when a generic version could become available. Until an approved generic is sold, do not buy any so-called "generic Trizivir," as it could potentially be dangerous.

Generic Trizivir: An Overview

Trizivir® (abacavir/lamivudine/zidovudine) is a prescription HIV and AIDS medication. It contains three different medications, all of which belong to a group of medications known as nucleoside reverse transcriptase inhibitors (NRTIs).
Trizivir is made by GlaxoSmithKline. There are no generic versions of Trizivir available in the United States. Yet, if you search the Internet for "generic Trizivir," you may find a number of companies selling it.
The fact is, these medicines could be fake, substandard, and potentially dangerous. There may be generic Trizivir available from another country, but there is really no way of knowing whether you are getting genuine Trizivir. You should not buy any generic Trizivir until there is an approved generic available.

When Will Generic Trizivir Be Available?

The first three patents for Trizivir expired in 2009. It is unclear why generic versions are not yet available. Perhaps the other listed patents (the next of which is set to expire in May 2010) provide protection against generic competition.
When multiple patents are listed (as is the case with Trizivir), it is often unclear which patents provide true protection against generic competition. In addition, the patent issues surrounding drugs with multiple active ingredients (like Trizivir) are often quite complicated. Therefore, it is difficult, if not impossible, to predict when exactly a generic Trizivir will become available.
