• Generic Name: cobicistat

• Other Brand Names: Tybost

Tybost (cobicistat) reduces the action of enzymes in your liver that break down certain antiviral medicines. This allows the antiviral medicines to be used more safely and effectively at lower doses.

Tybost is given together with atazanavir (Reyataz) or darunavir (Prezista) to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS).

Tybost is used to increase your blood levels of these medicines, helping to make them safer and more effective at lower doses.

When given with atazanavir, Tybost is for use in adults and in children who weigh at least 77 pounds (35 kilograms). When given with darunavir, Tybost is for use only in adults.

Tybost is not an antiviral medicine and will not treat HIV or AIDS. It is given only to help increase your blood levels of atazanavir or darunavir.
