I have a prescription for hydrocodone. If I take Benadryl (diphenhydramine) along with it, will it decrease my chances of nausea?
No. Benadryl typically only helps with allergy like symptoms. Nausea is best treated with medicines like Phenergan (promethazine) or zofran. You may need to speak with your doctor to discuss these options. Often times changing your pain medicine to another one will resolve your nausea, again speak with your doctor.
No . It won't help if you have history of narcotic induced nausea and vomiting. Why are you using hydrocodone? What about trying non-narcotic medicine like tylenol (acetaminophen) or aleve. Any chronic pain syndrome? Don't use hydrocodone if not recommended by your physician with close follow up by him.
