Interactions between your drugs

Moderate

saquinavir oritavancin

Applies to: saquinavir and oritavancin

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with drugs that are inducers of CYP450 3A4 may decrease the plasma concentrations of protease inhibitors (PIs), which are primarily metabolized by the isoenzyme.

MANAGEMENT: Given the risk of reduced viral susceptibility and resistance development associated with subtherapeutic antiretroviral drug levels, protease inhibitors should be used cautiously with agents that induce CYP450 3A4, particularly if only one PI is used in the antiretroviral regimen. Coadministration of atazanavir without ritonavir and carbamazepine, phenobarbital, or phenytoin is not recommended. Antiretroviral response should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the antiretroviral regimen adjusted as necessary.

Drug and food interactions

Moderate

saquinavir food

Applies to: saquinavir

Food can enhance the levels of saquinavir in your body. Saquinavir should be taken with meals or within 2 hours after eating. This will make it easier for your body to absorb the medication. Grapefruit can raise the levels of saquinavir in your body. Discuss the use of grapefruit products with your doctor. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
