The main reason why you should not have intercourse with Clotrimazole vaginal tablets is because: 1. If you have intercourse during the medication, some of the medication will flow out of the vagina, which will lead to a decrease in the efficacy of the medication and make the treatment effect not reach the desired effect. 2. If the male partner is allergic to Clotrimazole vaginal tablets, once the male partner has intercourse, it will lead to glans or foreskin edema and serious itching, so intercourse is not allowed during the use of the drug.
