Can you mix phenergan and norflex?

Mixing Phenergan (promethazine) and Norflex (orphenadrine) should be done with caution and under the guidance of a healthcare professional. Both medications have sedative effects, and combining them can increase the risk of side effects such as drowsiness, dizziness, and respiratory depression. Always consult a doctor or pharmacist before mixing medications to ensure safety and efficacy.
