Interactions between your drugs
sildenafil tecovirimat
Applies to: Revatio (sildenafil) and TPOXX (tecovirimat)
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with tecovirimat may decrease the plasma concentrations of drugs that are primarily metabolized by CYP450 3A4. Tecovirimat is a weak inducer of CYP450 3A4. In a drug interaction study involving 24 healthy subjects, a single 2 mg dose of midazolam was coadministered with tecovirimat (600 mg twice daily), and the midazolam peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 39% and 32%, respectively.
MANAGEMENT: The potential for diminished pharmacologic effects of CYP450 3A4 substrates should be considered during coadministration with tecovirimat.
Drug and food interactions
sildenafil food
Applies to: Revatio (sildenafil)
If you are receiving therapy with sildenafil you should avoid the regular consumption of large amounts of grapefruits and grapefruit juice. Grapefruit can raise the levels of sildenafil in your body and delay the time it takes for the medication to work. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
tecovirimat food
Applies to: TPOXX (tecovirimat)
Food may increase the absorption of tecovirimat when taken orally, which may lead to higher blood levels of the medication. You should take oral preparations of tecovirimat within 30 minutes after a full meal containing moderate or high fat (approximately 600 calories and 25 g of fat) with 6 to 8 ounces of water.
