Butenafine Hydrochloride vs Clotrimazole for Jock Itch and Ringworm – Uses & Side Effects

Butenafine Hydrochloride vs Clotrimazole for Jock Itch and Ringworm – Uses & Side Effects

Jock itch, also called tinea cruris, is a contagious skin infection caused by a type of fungus called dermatophytes (they are the most widespread superficial fungal infections among human beings).

Jock itch can spread from another person, either via sharing items (like – towels or clothing) or direct contact.

Common symptoms include:

  • scaly, red or brown patches;
  • cracked or flaking skin;
  • burning sensation around the affected area;
  • persistently itchy skin in the groin area;
  • a red rash with raised edges – typically on the groin, inner thighs, skin folds, or buttocks.

Ringworm, also known as tinea corporis, is a fungal infection that is caused by a fungus that can live on the skin, household items (like towels), and surfaces (such as locker room floors) and clothes.

Children under 15 are especially susceptible to this infection.

Tinea corporis can appear on just about any part of the body.

Common symptoms include:

  • hair loss in the affected area;
  • a ring-shaped rash;
  • red, scaly, or cracked skin;
  • itchy skin.

Tinea corporis is highly contagious and can be spread from individual to individual, as well as from household pets or by clothing used by an affected individual.

Treatment

Over-the-counter antifungal sprays, creams, or powders may solve these problems.

Here is a comparison of two antifungals that can be used for the treatment of jock itch and ringworm:

Butenafine Hydrochloride

It is an antifungal medicine which fights infections caused by fungus.

It can be found under the brand names of Lotrimin and Mentax.

ClotrimazoleClotrimazole
