Was prescribed lotrisone (clotrimazole and betamethasone) for a stubborn yeast infection under my breasts, its working great but how long is safe to continue use?

Couple of weeks: Use the cream for a couple of weeks, or until the rash is resolved, then keep the area cool clean and dry. You can use an otc powder like zeasorb af to prevent recurrence. If needed restart the cream. Try not to use it longer then two weeks without a break because of the steroid component of the cream.

Yeast : Lotrisone (clotrimazole and betamethasone) contains a steroid and antifungal in combination. Over time the steroid component will worsen the yeast infection. If Lotrisone (clotrimazole and betamethasone) is used it should only be for a short time to reduce redness and irritation but not long term.

Lotrisone (clotrimazole and betamethasone) : Lotrisone (clotrimazole and betamethasone) combines a very weak antifungal/antiyeast med with a very strong cortisone, so not certain what this med treats. When applied to body folds for even a few weeks, Lotrisone (clotrimazole and betamethasone) can cause thinning of skin, stretchmarks, dilated blood vessels, etc. For yeast infections under breasts, there are better antifungal (without cortisones) medications that would help. Please do not use this one.
