Monistat is a medication that treats vaginal yeast infections, explains WebMD. The medication helps stop the growth of yeast thereby eliminating the itching, burning and discharge that often occur with the condition.
There are a few known possible side effects of Monistat, including vaginal burning, pain or itching, claims WebMD. Headache may also occur with this medication, and if these side effects get worse or persist, the user should contact a doctor or pharmacist. Most women who use this medication do not have serious side effects, and a serious allergy to the drug is not common; however, if a woman experiences severe dizziness, rash, swelling or itching around the face or throat and trouble breathing, she must obtain emergency medical treatment.
Using Monistat can weaken rubber products, such as diaphragms and condoms, according to WebMD. This can stop the effectiveness of these products and raise the chances of pregnancy. These effects can occur up to three days following the last dose of Monistat. There are alternatives for birth control during this time, however, such as using polyurethane condoms. Women must also not use this treatment if pregnant without consulting a doctor. The doctor may advise pregnant women to use a different product or apply the product in a different way.
