Interactions between your drugs

Moderate

fluvoxaMINE valdecoxib

Applies to: Luvox CR (fluvoxamine) and valdecoxib

MONITOR: Coadministration with inhibitors of CYP450 2C9 and/or 3A4 may increase the plasma concentrations of valdecoxib, which is metabolized by these isoenzymes. According to the product labeling for valdecoxib, multi-dose administration of fluconazole (CYP450 2C9/3A4 inhibitor) and ketoconazole (CYP450 3A4 inhibitor) increased the area under the plasma concentration-time curve (AUC) of a single 20 mg dose of valdecoxib by 62% and 38%, respectively. Parecoxib, a prodrug of valdecoxib, may be similarly affected.

MANAGEMENT: The possibility of prolonged and/or increased pharmacologic effects of valdecoxib or parecoxib, including serious adverse effects such as gastrointestinal ulceration and bleeding, should be considered during concomitant therapy with CYP450 2C9 or 3A4 inhibitors, particularly combination (2C9/3A4) inhibitors such as fluconazole, fluvoxamine, imatinib, and zafirlukast. Dose reductions of the COX-2 inhibitor may be required.

Drug and food interactions

Moderate

fluvoxaMINE food

Applies to: Luvox CR (fluvoxamine)

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.

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.
