Invirase Dosage

Your Invirase dosage will be based on factors such as other medical conditions you have and other medications you are taking. It is always taken with ritonavir, which boosts the effectiveness of Invirase. The recommended Invirase dosage for people age 16 and older who have HIV or AIDS is 1000 mg twice daily with 100 mg of ritonavir twice daily.

Invirase Dosage: An Introduction

The dose of Invirase® (saquinavir mesylate) your healthcare provider recommends will vary, depending on a number of factors, including:
  • Other medical conditions you may have
  • Other medications you may be currently taking.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Invirase Dosage for HIV and AIDS

Invirase is always combined with ritonavir (Norvir®), another HIV medication that increases the level of Invirase in the blood, making it more effective. The recommended dose of Invirase for treating adults and adolescents age 16 and older with HIV or AIDS is Invirase 1000 mg twice daily with ritonavir 100 mg twice daily. Both medications should be taken at the same time. In order to get 1000 mg of Invirase, either five 200-mg capsules or two 500-mg tablets may be taken.

General Information on Dosing With Invirase

Considerations for people taking Invirase include the following:
  • The medication comes in the form of a capsule and a tablet. It is usually taken by mouth twice daily.
  • Invirase should be taken with a meal or within two hours after a meal. It is always used along with ritonavir, and Invirase and ritonavir should be taken at the same time.
  • Try to take Invirase at the same times every day to maintain an even level in your blood.
  • For the medication to work properly, it must be taken as prescribed. It is very important that you closely follow your healthcare provider's instructions on taking Invirase. Missing doses can increase the chance of the virus developing a resistance to Invirase, thereby making it less effective.
  • If you are unsure about anything related to your Invirase dosage, please talk to your doctor, nurse, or pharmacist. Do not stop taking the drug without first discussing it with your healthcare provider.
