Interactions between your drugs

Moderate

clorazepate tecovirimat

Applies to: Tranxene T-Tab (clorazepate) and tecovirimat

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

Moderate

clorazepate food

Applies to: Tranxene T-Tab (clorazepate)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate

tecovirimat food

Applies to: tecovirimat

ADJUST DOSING INTERVAL: Food may increase the extent of tecovirimat absorption following oral administration. When the recommended oral dose of tecovirimat (600 mg every 12 hours) was administered with a meal (approximately 600 calories and 25 g of fat) in healthy adults weighing less than 120 kg, tecovirimat absorption increased by 39% relative to fasting.

MANAGEMENT: Oral tecovirimat should be taken 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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
