PYRILAMINE-DEXTROMETHORPHAN (Generic for CAPRON DM)

Dextromethorphan Hydrobromide 7.5mg/5mL, Pyrilamine Maleate 7.5mg/5mL, Oral solution

Grapefruit juice

· Severity: Mild

· Notes for Consumers: Grapefruit juice may increase the actions of Dextromethorphan, which may make some people feel drowsiness or other side effects (dizziness, nervousness or restlessness, nausea, vomiting, stomach upset) of Dextromethorphan that do not usually occur with prescribed or nonprescription product doses. It may be best to limit intake of grapefruit juice while you are taking Dextromethorphan-containing products.

· Notes for Professionals: Intake of grapefruit juice or seville orange juice increased dextromethorphan bioavailability in one study. Patients with increased concentrations of dextromethorphan may experience drowsiness or serotonergic side effects (dizziness, nervousness or restlessness, nausea, vomiting, stomach upset) not usually noted with prescribed or nonprescription product doses. Grapefruit juice and seville orange juice contain compounds that can inhibit P-glycoprotein in the intestinal wall, and dextromethorphan absorption may be affected by P-glycoprotein activity. Dextromethorphan is largely metabolized by CYP2D6, so this particular interaction with grapefruit juice may be more relevant in patients who are poor CYP2D6 metabolizers.
