1. What Tybost is and what it is used for

Tybost contains the active substance cobicistat.

Tybost is used for the treatment of human immunodeficiency virus-1 (HIV-1) infection, the virus that causes acquired immune deficiency syndrome (AIDS). It is used in HIV-1 infected adults and adolescents aged 12 years and older:

• weighing at least 35 kg (when co-administered with atazanavir 300 mg) or
• weighing at least 40 kg (when co-administered with darunavir 800 mg).

Tybost acts as a booster (enhancer ) of atazanavir or darunavir (both protease inhibitors) to improve their effect (see section 3 of this leaflet).

Tybost does not directly treat your HIV, but boosts the levels of atazanavir and darunavir in the blood. It does this by slowing down the breakdown of atazanavir and darunavir which will make them stay in the body for longer.

2. What you need to know before you take Tybost
