    Ritonavir (By mouth)

    Ritonavir (By mouth)

    rit-OH-na-vir

    Treats HIV infection. This medicine does not cure HIV or AIDS, but combinations of drugs may slow the progress of the disease.

    Drug classes

    Antiretroviral Agent (About this – PubMed Health)

    Uses

    Uses of This Medicine

    Ritonavir is used alone or in combination with other medicines for the treatment of the infection caused by the human immunodeficiency virus (HIV). HIV is the virus that causes acquired immune deficiency syndrome (AIDS).

    Ritonavir will not cure HIV infection or prevent AIDS. It helps keep HIV from reproducing and appears to slow down the destruction of the immune system. This may help delay problems that are usually related to AIDS or HIV disease from occurring. Ritonavir will not keep you from spreading HIV to other people. People who receive this medicine may continue to have other problems related to AIDS or HIV disease.

    This medicine is available only with your doctor’s prescription.
