Ziagen is an oral tablet made up of a nucleoside reverse transcriptase inhibitor called abacavir. We carry Ziagen in both the brand name and generic alternative in 300mg!

Ziagen is often prescribed along with other medications to help control the human immunodeficiency virus (HIV). HIV is spread through human fluids such as blood, saliva, semen, and vaginal fluids. This virus will slowly weaken your immune system over time, which can become fatal if it progresses to AIDS. The immune system is the body’s “bodyguard” as it is in charge of defending the body against any threats, such as infections and disease. When HIV weakens your immune system so much to the point where it is no longer capable of fighting infections and diseases, you have AIDS. AIDS can be life-threatening if not treated as infections and diseases are able to thrive in your body without an immune system to fight them off.

Ziagen (abacavir) is effective at controlling HIV because of its power to stop the virus from growing more, and by doing this, it allows the immune system to work better. This also lowers your chance of getting AIDS and other HIV complications such as infections or cancer.
