SAQUINAVIR

About

SAQUINAVIR 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). This medicine is used in combination with ritonavir and other antiviral medicines.

SAQUINAVIR contains Saquinavir, 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. Therefore, SAQUINAVIR inhibits viral replication.

SAQUINAVIR may cause certain side effects such as nausea, headache, abdominal pain, loss of appetite, vomiting, depression, fever, tiredness, blood in urine, diarrhea, and itching. 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. SAQUINAVIR 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.

SAQUINAVIR should be avoided if you are allergic to it. This medicine is contraindicated in patients with congenital or documented acquired QT prolongation, AV block, anaphylactic reactions, Stevens-Johnson syndrome, use of SAQUINAVIR with ritonavir in severe hepatic impairment, combination of SAQUINAVIR and ritonavir with CYP3A substrates and rifampicin due to hepatotoxicity 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. SAQUINAVIR should be given to pregnant and breastfeeding women only if recommended by the doctor.

    Disease/Condition Glossary

    HIV Infection: Human Immunodeficiency Virus (HIV) is a retroviral infection that attacks and damages the cells of the immune system. This weakens the ability to fight against infections and diseases. If this condition is left untreated, it can lead to Acquired Immuno Deficiency Virus (AIDS). Symptoms of HIV include headache, fever, chills, joint pain, fatigue, swollen lymph nodes, sore throat, mouth nodes, muscle aches, etc. SAQUINAVIR helps reduce the symptoms, control the infection, and also helps improve the HIV patient’s quality of life.
