What do i use for itchy vaginal latex allergic reaction?

Over the counter: Over the counter Benadryl (diphenhydramine) is low dose, and can safely be taken as directed. The main side effect is drowsiness. Hydrocortisone cream (also otc) can be used a time or two outside your vagina to address some of the reaction as well. Of course, best thing is to avoid being exposed to latex - that can be a serious allergic reaction, so avoid recurrent exposures.

Change brands?: If one type of condom causes an allergic reaction, you might try changing brands. It may be the spermicidal powder on the condum causing the reaction rather than the latex itself.

First, avoid latex: A short course of a topical steroid can help reduce the allergic reaction. Taking a close look at how you may be coming into contact with latex, and modifying your activities to avoid it will help you to prevent further events. See a dermatologist certainly if this problem continues.
