What is 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.

Important Information

Tybost is not a complete treatment and must be used in combination with other antiviral medicines your doctor has prescribed. However, there are certain antiviral medicines that should not be taken in combination with cobicistat. Follow your doctor’s medication and dosing instructions very carefully.

Tybost is recommended for use only with atazanavir or darunavir. You should not take this medicine with other protease inhibitor HIV medicines, such as fosamprenavir, nelfinavir, saquinavir, or tipranavir.

You should not take cobicistat with darunavir if you are taking darunavir twice daily. You should not take cobicistat with atazanavir if you also take indinavir, irinotecan, or nevirapine.

Many drugs can interact with cobicistat and some should not be used at the same time. Tell your doctor about all your current medicines and any you start or stop using.

  • If you take a medicine such as cimetidine, ranitidine, Tagamet, Axid, Zantac, Pepcid, and others: Take the stomach medicine at the same time you take Tybost and atazanavir; or wait at least 10 hours after taking the stomach medicine to take your Tybost and atazanavir doses.

While using Tybost, your blood may need to be tested often. Your kidney function may also need to be tested.

Use all HIV medications as directed and read all medication guides you receive. Do not change your dose or dosing schedule without your doctor’s advice. Every person with HIV should remain under the care of a doctor.
