Can I take TYLENOL® Cold Severe Congestion Daytime with a monoamine oxidase inhibitor (MAOI)?
This product contains pseudoephedrine hydrochloride and dextromethorphan hydrobromide as active ingredients. The use of pseudoephedrine hydrochloride with an MAOI drug such as Nardil (phenelzine) and Parnate (tranylcypromine) may cause a reaction characterized by a headache and other serious symptoms (including convulsive seizures) due to a rise in blood pressure. The use of dextromethorphan hydrobromide with an MAOI drug may cause excitation, seizures, delirium and other serious symptoms.
