Atazanavir
About Atazanavir
Atazanavir is an antiretroviral medicine used in the treatment of HIV infection. HIV is a retroviral infection that attacks and destroys immune cells. This reduces the body's ability to fight infections and illnesses. If this condition is left untreated, it can lead to Acquired Immuno Deficiency Syndrome (AIDS). Symptoms of HIV include fever, chills, night sweats, muscle aches, etc.
Atazanavir contains Atazanavir, which belongs to the class of protease inhibitors. It works by inhibiting the protease enzyme production, which is required for the HIV-infected cells to make new viruses. This causes inhibition of viral replication.
Atazanavir may cause certain side effects such as nausea, headache, stomach pain, loss of appetite, vomiting, depression, fever, tiredness, back pain, blood in urine, diarrhea, muscle pain, dizziness, and allergic reactions. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist, please consult your doctor. Atazanavir should be taken as advised by your doctor. Your doctor will decide the dose of the medicine based on your health condition. Do not take more than the recommended dose.
Atazanavir should be avoided if you are allergic to it. It is contraindicated in patients with Stevens-Johnson syndrome, erythema multiforme or patients taking alfuzosin, triazolam, orally administered midazolam, ergot derivatives, rifampin, irinotecan, lovastatin, simvastatin, indinavir, cisapride, pimozide, as it can cause serious side effects. Hence avoid using this medicine under such conditions. Inform your doctor if you have any cardiovascular conditions, liver/kidney disease, diabetes, or immune reconstitution syndrome on priority. Atazanavir should be given to pregnant and breastfeeding women only if recommended by the doctor. Atazanavir is not recommended for children below six years of age as safety and efficacy are not established.
