My husband has a severe dry, scaly rash all over his body, and he s prescribed Morphine 15 s. He s prescribed 9 of them daily. He s been on Morphine for almost 10 years now. Up until about a year and a half ago he only was prescribed 90 milligrams daily. Then we found out he had stage 4 throat cancer, and his doctors put him on nine 15 milligrams daily. He s been cancer free for almost a year now, but he s still prescribed the nine 15s a day. My question is, could he be having an allergic reaction to the amount of Morphine in his system, and also the amount of time he s been prescribed Morphine?
