Can you mix Benadryl and tussin cf?

Mixing Benadryl (diphenhydramine) and Tussin CF, which contains guaifenesin and other active ingredients, is generally not recommended without consulting a healthcare professional. Both medications can cause sedation, and combining them may increase the risk of side effects such as drowsiness or dizziness. Always check with a doctor or pharmacist before mixing medications to ensure safety and efficacy.
