Interactions between your drugs
naproxen viloxazine
Applies to: Sinus & Cold D (naproxen / pseudoephedrine) and viloxazine
MONITOR: Coadministration with viloxazine, a potent CYP450 1A2 inhibitor may increase the plasma concentrations of CYP450 1A2 substrates leading to increased toxicity. According to the prescribing information, viloxazine increased the systemic exposure (AUC) of caffeine, a probe CYP450 1A2 substrate, by nearly 6-fold without affecting its peak plasma concentration (Cmax).
MANAGEMENT: Monitor for toxicities of CYP450 1A2 substrates whenever viloxazine is added to or withdrawn from therapy. Adjust doses of CYP450 1A2 substrates as clinically indicated.

Drug and food interactions
naproxen food
Applies to: Sinus & Cold D (naproxen / pseudoephedrine)
GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.
MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

pseudoephedrine food
Applies to: Sinus & Cold D (naproxen / pseudoephedrine)
MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.
MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.
