I drank lortab last night for pain with the teeth extractions and i feel very nauseous this morning is that normal?

Yes: Lortab contains hydrocodone which is an opioid. Common reactions are nausea and vomiting, constipation, dizziness, and drowsiness.

Yes: Some medications, like narcotic pain meds, can cause you to feel nauseous. The stress from the procedure, medications and swallowing some mucous and blood will upset you normal balance. Try to keep something on the stomach, bland(like toast and tea), and allow yourself to recover. It will pass. If it continues for a few days let your doctor know.
