Bactrim is a mixture of sulfamethoxazole and trimethoprim which are both antibiotics that have been medically approved to treat harmful bacteria that cause infections.
There are patients that are okay with Bactrim while there are those that experience side effects and one of the most common ones are allergic reactions.
These patients that have allergic reactions often have immune systems that react poorly to certain drugs.
