I have RA, OA, fibromyalgia, and have had 3 back surgeries. I take an IV fusion of Orencia every 4 weeks. I have been taking Percoset for 3 years. It worked ok but all of a sudden I started itching terribly! The Rheumatalogist put me on the Fentanyl patches yesterday. It didn't seem to make me itch last night but terribly today. I have been taking Benadryl but still itch. I have to have some type of pain medicine. Is Lortab in the same family as these two pain meds? The patch is great for the pain even on lowest dose but the itching is driving me crazy!
