Atazanavir+ritonavir
About
Atazanavir+ritonavir belongs to the class of medications called ‘antiretroviral agents’ used to treat HIV infection. HIV is a virus that attacks the immune cells of the body leading to decreased immunity. It spreads through body fluids such as semen, vaginal fluid, and blood. Symptoms include fever, chills, rash, night sweats, muscle aches, tiredness, and sore throat that usually last for days to several weeks.
Atazanavir+ritonavir is a combination of Atazanavir and Ritonavir. These drugs belong to the class of protease inhibitors. They work by inhibiting the protease enzyme production, which is required by the HIV-infected cells to make new viruses. This effect helps to inhibit viral replication.
Take Atazanavir+ritonavir exactly as prescribed by the doctor. Atazanavir+ritonavir may cause side effects such as stomach ache, diarrhoea, feeling sick (nausea), vomiting (being sick), flushing (reddening of the skin), headache, dizziness, pain in the throat, cough, upset stomach, a tingling sensation or numbness in the hands, feet or around the lips and mouth, bad taste in the mouth, damage to the nerves that can cause weakness and pain, itching, rash, joint pain and back pain, dyspepsia (indigestion), and fatigue (tiredness). Inform your doctor if any of these side effects persist or get worse.
It is not recommended to take Atazanavir+ritonavir if you are allergic to any contents of it.

Uses of Atazanavir+ritonavir
Medicinal Benefits
Atazanavir+ritonavir belongs to the group of medicines called antiretroviral therapy (ART). Atazanavir+ritonavir is a fixed-dose combination (FDC) and contains atazanavir and ritonavir. FDC helps decrease drug resistance (reduction in medication effectiveness) as HIV can easily develop drug resistance. Atazanavir+ritonavir helps reduce the symptoms, control the infection, and prevent opportunistic infections effectively. It further helps in improving the quality of life of a patient with HIV.

Patients Concern
Disease/Condition Glossary
HIV infection: HIV (human immunodeficiency virus) is a virus that attacks the immune system, making the individual susceptible to other infections or illnesses. People with HIV experience flu-like symptoms such as fever, chills, rash, night sweats, muscle aches, tiredness, and sore throat. These symptoms usually last for days to several weeks. It spreads through body fluids such as semen, vaginal fluid, and blood. If left untreated, this condition can lead to AIDS (Acquired Immunodeficiency Syndrome). It is a life-long condition, and there is no definite cure for it. However, it can be controlled by treating with antiretroviral agents.
