Why is this medication prescribed?

Invirase, also known by its generic name saquinavir, is a prescription medication primarily used in the treatment of HIV (human immunodeficiency virus) infection. It belongs to a class of medications called protease inhibitors, which work by inhibiting the activity of the HIV protease enzyme. This enzyme is essential for the replication of the virus, and by blocking its action, Invirase helps to reduce the amount of HIV in the body, slow down the progression of the disease, and improve the immune system.

Invirase is usually prescribed as part of a combination therapy for HIV infection. It is typically used in combination with other antiretroviral drugs to maximize its effectiveness and reduce the risk of developing drug resistance.

How should this medicine be used?

Invirase is a medication that contains the active ingredient saquinavir, which belongs to a class of drugs known as protease inhibitors. It is primarily used in the treatment of HIV infection. Here are the general guidelines for using Invirase:

• Combination Therapy: Invirase is always used in combination with another HIV medication called ritonavir. Ritonavir is used to boost the levels of saquinavir in the blood, increasing its effectiveness.
• Prescription and Dosage: Invirase should be prescribed by a healthcare professional experienced in the management of HIV infection. The dosage will depend on various factors, including the patient’s overall health, other medications being taken, and individual treatment response.
• Oral Administration: Invirase is available in the form of tablets or capsules and is taken orally. The specific instructions regarding the number of tablets or capsules and the frequency of dosing will be provided by the prescribing physician.
• Food Intake: Invirase should be taken with a meal or within 2 hours of a meal. This is important as it helps improve the absorption of the medication in the body.
• Adherence: It is crucial to take Invirase exactly as prescribed by the healthcare professional. Skipping doses or not following the prescribed schedule can reduce the effectiveness of the medication and increase the risk of HIV treatment failure.

Other uses for this medicine

What special dietary instructions should I follow?

Here are the special dietary instructions for Invirase:

• Take Invirase with Food: It is recommended to take Invirase with a meal or a substantial snack containing at least 500 calories and at least 20 grams of fat. This helps improve the absorption of the medication into your body.
• Avoid Grapefruit and Grapefruit Juice: Grapefruit and grapefruit juice can interact with Invirase and increase the levels of the medication in your body. This can lead to a higher risk of side effects. Therefore, it is best to avoid consuming grapefruit or grapefruit juice while taking Invirase.

What should I do if I forget a dose?

If you forget to take a dose of Invirase, here’s what you should do:

• Take the missed dose as soon as you remember: If you remember within a few hours of the scheduled dose, take the missed dose immediately. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule.
• Do not double the dose: Do not take a double dose to make up for the missed dose. Taking more than the prescribed amount can increase the risk of side effects without providing any additional benefit.
• Contact your healthcare provider: If you are unsure about what to do or if you have missed multiple doses, it is recommended to contact your healthcare provider or pharmacist for further guidance. They can provide you with specific instructions based on your individual circumstances.

What side effects can this medication cause?

Invirase is the brand name for the medication saquinavir, which is an antiretroviral drug used in the treatment of HIV (human immunodeficiency virus) infection. While Invirase is effective in managing HIV, it may also cause certain side effects. It’s important to note that not everyone who takes Invirase will experience these side effects, and the severity and frequency can vary from person to person. Some potential side effects of Invirase include:

• Gastrointestinal issues: Invirase can cause gastrointestinal disturbances such as nausea, vomiting, diarrhea, and abdominal discomfort. These symptoms are usually mild to moderate in severity and may subside over time.
• Liver problems: Saquinavir has been associated with liver toxicity, including elevated liver enzymes and in some cases, hepatitis. Regular monitoring of liver function is necessary during treatment with Invirase.
• Cardiovascular effects: Invirase may prolong the QT interval, which is an electrical measurement of the heart’s activity. Prolongation of the QT interval can lead to an irregular heart rhythm called torsades de pointes. This side effect is rare but serious and may require discontinuation of the medication.
• Skin reactions: Some individuals may develop skin rashes, including Stevens-Johnson syndrome or toxic epidermal necrolysis, which are severe and potentially life-threatening conditions. These reactions require immediate medical attention.
• Metabolic changes: Invirase can affect lipid and glucose metabolism, leading to increased levels of cholesterol, triglycerides, and blood sugar. Regular monitoring of these parameters is important, especially in individuals with pre-existing metabolic conditions.
• Immune system effects: Saquinavir can cause immune reconstitution inflammatory syndrome (IRIS) in individuals with advanced HIV infection. IRIS occurs when the immune system starts to recover and becomes overly active, resulting in inflammatory reactions against previously existing infections.
• Drug interactions: Invirase can interact with various medications, including other HIV drugs and non-HIV medications. These interactions can lead to reduced effectiveness of either medication or increased risk of side effects. It is crucial to inform your healthcare provider about all the medications you are taking to avoid potential interactions.

It’s essential to consult with a healthcare professional for a comprehensive understanding of the potential side effects and risks associated with Invirase. They can provide personalized information based on your specific medical history and guide you through the appropriate use of the medication.
