Invirase (saquinavir) is a medication used in the treatment of HIV/AIDS. It belongs to a class of drugs known as protease inhibitors. Saquinavir works by inhibiting the activity of the protease enzyme, which is necessary for the HIV virus to replicate and spread within the body.
The usual dosage of Invirase (saquinavir) tablets for adults is 1000 mg (two 500 mg tablets) taken orally twice daily with ritonavir 100 mg. Ritonavir is often used as a "booster" medication to increase the levels of saquinavir in the body by inhibiting its metabolism. This combination is commonly used in HIV treatment regimens to enhance the effectiveness of saquinavir.
It's important to take Invirase (saquinavir) exactly as prescribed by your healthcare provider and to not miss any doses. Skipping doses or not taking the medication as directed can lead to decreased effectiveness and potential development of drug resistance.
Additionally, like all medications, Invirase (saquinavir) may cause side effects, and it's essential to be aware of these and report any unusual symptoms to your healthcare provider. Common side effects may include gastrointestinal disturbances, changes in liver function tests, and interactions with other medications.
If you have any questions or concerns about Invirase (saquinavir) or its use, you should consult your healthcare provider or pharmacist for guidance. They can provide you with personalized advice based on your specific medical history and treatment needs.
