This combination product contains two medications: betamethasone and clotrimazole. It is used to treat itchy, inflamed skin rashes caused by certain types of fungus (e.g., athlete's foot, jock itch, ringworm).

What is Lotriderm used for?

  • Fungal skin infections, eg athlete's foot, ringworm, candida skin infections, sweat rash.
  • Lotriderm cream is used to treat fungal skin infections when symptoms of inflammation, such as itching, require rapid relief. The clotrimazole treats the infection, while the betamethasone reduces the associated redness and itching.

How does Lotriderm work?

  • Lotriderm cream contains clotrimazole and betamethasone diproprionate.
  • Clotrimazole is an antifungal medicine that kills fungi and yeasts by interfering with their cell membranes. It works by stopping the fungi from producing a substance called ergosterol, which is an essential component of fungal cell membranes. The disruption in production of ergosterol causes holes to appear in the fungal cell membrane. This kills the fungi and treats the infection.
  • Betamethasone is a potent corticosteroid.
It reduces skin inflammation by stopping skin cells from producing various inflammation-causing chemicals that are normally released when the skin reacts to irritation. These inflammation-causing chemicals include prostaglandins and various other inflammatory substances. They cause blood vessels to widen and other inflammatory substances to arrive, resulting in the affected area of skin becoming red, swollen and itchy. By preventing these inflammatory chemicals from being released in the skin, betamethasone reduces inflammation and relieves its related symptoms such as redness and itchiness.

How do I use Lotriderm?

  • Lotriderm cream should be applied thinly and evenly to the affected area(s) of skin twice a day. 
  • Wash your hands after applying the cream, unless the hands are the area being treated.
  • The cream should be used for two weeks to treat ringworm or candida infections and for four weeks to treat athlete's foot.
  • Make sure you keep using the cream for the length of time prescribed by your doctor. If you stop using it too early because the symptoms have cleared up, the infection may come back.
  • If you are using Lotriderm cream to treat athlete's foot you should make sure you wash and dry the feet, especially between the toes, before applying the cream. You may also want to use an antifungal powder inside your socks and shoes to help treat the infection and prevent it coming back.
  • Do not cover the area being treated with airtight dressings such as bandages or other dressings, as these will enhance the absorption of the medicine into the body and may increase the risk of side effects from the steroid.
  • If your skin seems to be getting more irritated, or an infection has not cleared up after the course of treatment has finished, you should consult your doctor.

Lotriderm should be used with caution in

  • Children. Lotriderm cream is not licensed for children under 12 years of age.
  • Psoriasis. If you have been prescribed this medicine to treat areas of skin affected by psoriasis you should have regular check-ups with your doctor. This is because although corticosteroids may be useful for psoriasis in the short-term, they can sometimes make psoriasis worse, and may cause the condition to relapse into generalised pustular psoriasis after the treatment is stopped.
