If you are not allergic to antihistimines or have severe allergic reactions to insect bites or stings, which requires medicial attention, this advice is helpful.
For bee or wasp stings or spider bites, once your have removed the stinger from a bee or wasp sting, take an antihistimine immediately; the same applies for a spider bite.
Any over the counter antihistimine will do. (ie. clor-trimeton, benedryl etc.), then proceed with topical remedies to soothe the pain and reduce swelling.
