Clotrimazole-betamethasone is a combination medication used topically on the skin to combat topical fungal infections such as athlete’s foot and ringworm disease. This formulation cream contains two active principles, clotrimazole and betamethasone. It can also be used for other conditions; contact your physician if you have any queries.
Common brand name of Clotrimazole and betamethasone
Lotrisone (Clotrimazole and betamethasone dipropionate cream) is a combination of an azole antifungal (Clotrimazole) and corticosteroid (Betamethasone dipropionate cream), for tropical use.
Forms of medication available
- Cream (15g, 45g)
- Lotion (30 mL)
Function of clotrimazole
Clotrimazole is an antifungal that belongs to the azole subgroup. It prevents the formation of a component of the fungal cell membrane called ergosterol by interfering at the lanosterol synthesis step. In this way, there is a failure to form the fungal cell membrane, and hence it retards fungal growth when applied to the skin.
The function of betamethasone
Betamethasone is a corticosteroid that inhibits the phospholipase A2 enzyme and inhibits arachidonic acid and prostaglandins synthesis. This results in suppressing the inflammatory reaction at the infection site, reducing swelling, itching, and redness.
Diseases for which you can use it
It is an antifungal and can be used to treat topical fungal infections called dermatophytoses (epidermophyton and trichophyton), such as:
- Athlete’s foot or jock itch
- Tinea capitis (topical fungal infection of head)
- Topical fungal infection of the groin: Tinea cruris
- Tinea pedis (topical fungal infection of feet)
- Topical fungal infection of the trunk: Tinea corporis
Directions for use

Do not wrap or cover the area with any cloth or bandage.
