Re: Does the Influenza Vaccination have sulfa in it?
You can ask the health professional who gives the injections and ask for a copy of the information on the serum. It will state what you need to know.
BTW, All drugs that contain sulfa related components list a potential side effect of that. In fact, just because one is allergic to sulfa drugs ( a certain family of antibiotics) does not mean that one will have problems with all drugs which show a sulfa caution. I am allergic to sulfa antibiotics but usually tolerate other drugs with a sulfa caution with nothing more than an upset digestive tract - albeit an often severe issue.
