What is the dosage for Lotrisone (clotrimazole and betamethasone)?
- Lotrisone cream is gently massaged into the affected skin and surrounding area in the morning and evening. The treated skin should not be bandaged, covered, or wrapped in order to avoid excessive absorption of Lotrisone into the body.
- Lotrisone cream or lotion should not be used for more than 2 weeks for treatment of tinea corporis or tinea cruris. If there is no clinical improvement after one week of treatment, the diagnosis should be reviewed.

These limits on duration of use are based on the clinical studies that were used by the FDA to approve Lotrisone and concerns that with longer use absorption of betamethasone might be enough to have effects on the body.
