Drug Interaction Report

Tecovirimat may reduce the blood levels of midazolam, which may make the medication less effective in some cases. Contact your doctor if your symptoms worsen or your condition changes. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Grapefruit and grapefruit juice may interact with midazolam and lead to potentially dangerous side effects. 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. Do not drink alcohol while taking midazolam. This medication can increase the effects of alcohol. You may feel more drowsy, dizzy, or tired if you take midazolam with alcohol. Talk to your doctor or pharmacist if you have any questions or concerns.

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.
