Can I take clonazepam, ibuprofen, and meclizine all at once?

Depends on the dose. The short answer is yes, but the combination of Clonazepam and Meclizine can cause drowsiness, nausea, vomiting. Dizziness and headache. Additionally, if you take Ibuprofen on an empty stomach, you can irritate your stomach which can cause pain, nausea and vomiting as well. So, be very careful.
Careful. Meclizine and clonazepam both can make make you drowsy. Combined can make it worse. Check with your doctor or make an appointment with me through HealthTap Prime to discuss this further in detail.
