• Avoid concomitant use of strong CYP3A4 inhibitors or inducers.

Avoid coadministration of strong CYP3A4 inhibitors or consider alternative medication that are not strong CYP3A4 inhibitors.

If concomitant use of strong CYP3A4 inhibitors cannot be avoided, closely monitor for adverse drug reactions.

( ‎7.2 ) 7.1 Effect of Other Drugs on HEMADY Strong CYP3A4 inhibitors Coadministration of strong and moderate CYP3A4 inhibitors increased dexamethasone exposure [see Clinical Pharmacology (‎ 12.3 )] , which may increase the risk of adverse reactions [see Warnings and Precautions (‎ 5 ) and Adverse Reactions (‎ 6 )] .

Coadministration of fluticasone and fosamprenavir calcium/ritonavir is not recommended unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects.

Initiation of medications that inhibit or induce CYP3A may increase or decrease concentrations of fosamprenavir calcium/ritonavir, respectively.

Coadministration of fosamprenavir calcium with drugs that induce CYP3A4 may decrease amprenavir (active metabolite) concentrations leading to potential loss of virologic activity.

Coadministration of fosamprenavir calcium and drugs that induce CYP3A4, such as rifampin, may decrease amprenavir concentrations and reduce its therapeutic effect.

Corticosteroid: Dexamethasone ↓ Amprenavir Use with caution.
