My husband is suffering with severe sciatica. The ER prescribed 325/5 Hydrocodone 1-2 tablets every 6 hours. He took a dose approximately 1:00 a.m., but he has not been able to sleep for two nights due to the pain. His pain is very bad right now and we are trying to treat it with ice right now (3:20 a.m. CT) Can I give him something OTC that won t cause a problem with the Hydrocodone? He is also taking Xarelto. Thanks for your help.
