In brief: Antihistamine
Stop bactrim.
You may want to take Benadryl (diphenhydramine) for your hives. Other medication that you can take if Benadryl (diphenhydramine) is not enough - include- other antihistamine like ranitidine , or claritin, zyrtec, Allegra etc . If otc medication does not help or symptoms get worse- see your md or urgent care.
