Re: Sulfa drug allergy - can I take Avinza (morphine sulfate)?
I checked the mayoclinics web site, someone had asked about sulfa antibiotics and sulfates. here is their reply "Sulfa isn't the same as sulfate. Sulfa is short for sulfamethoxazole. Some people are allergic to sulfa antibiotics such as sulfamethoxazole, which is found in the combination antibiotics Bactrim and Septra. Sulfate, also spelled sulphate, is a chemical term that identifies specific salts containing sulfur. Sulfur is a mineral that's found naturally in animal protein (including meat, poultry, fish and eggs), dried beans and other vegetables. Sulfa antibiotics don't contain sulfates.
For these reasons, people who are allergic to sulfa antibiotics wouldn't be allergic to dietary supplements containing sulfates. The most common allergic reaction to sulfa drugs is a skin rash. There's no reliable test for allergy to sulfa antibiotics. A doctor may make a diagnosis of sulfa allergy based on the signs and symptoms."
Accordingly you should be alright with either MScontin, Avinza or Kadian.
GOD bless and be Comfortable!!
