What other medications can you take other than hydrocodone for pain?

Anti-Inflamatories such as ibuprofen are not contra-indicated based on taking codeine. You would also be able to take Paracetamol (unless your codeine is in co-codamol). I would advise against taking Naproxen with Aspirin due to interactions and also Iburopen, as both it and Naproxen are NSAIDS. The use of these additional pain killers would be dependent on you own personal history of taking OTC drugs. If you are still in pain, despite your current prescription, I would advise speaking to your physician/pharmacist/pain nurse regarding a medication review.
