I am allergic to sulfur or sulfa. Can I take Flexcin?
This is a quite common question and concern. People are not allergic to sulfur. Rather, they are allergic to “SULFA”. Sulfa is a component in many drugs including Celebrex® and Bextra®. If you are allergic to sulfa, you may be sensitive to these other pain killers. Sulfa is also referred to as a “sulfonyl group” containing a sulfur atom attached to a pair of oxygens in the middle of a larger molecule. Sulfur on the other hand is necessary for many bodily and cellular functions. It is found in common foods such as onions and garlic and is absolutely required for proper joint function. MSM contains sulfur and that is one of the reasons that it is so beneficial for diminishing joint and other pains.
