Clotrimazole 1 cream is used to treat a wide range of skin infections caused by fungi. These include infections with dermatophytes such as tinea, eg ringworm tinea corporis, athletes foot tinea pedis, and jock itch tinea cruris and infections with yeasts such as candida, eg fungal nappy rash, sweat rash, or thrush affecting the outside of the vagina vulva and labia or the end of the penis.consult your doctor before using this medicine if you are unsure of the cause of your infection, or you have not had it before.clotrimazole cream is for external use only.clotrimazole cream may damage latex rubber condoms and diaphragms caps and so make them ineffective at preventing pregnancy and stis. If you are using this cream to treat the vagina or penis you should use an alternative method of contraception for at least five days after using the cream, or preferably avoid having sex until after the infection has cleared up. Remember that having sex while you still have the infection is likely to transmit the infection to your partner, who could then transfer it back to you.if your sexual partner also has symptoms of thrush it is important that they are treated at the same time as you to prevent you being reinfected. Clotrimazole 1 cream contains the same active ingredient as canestan cream.packaging may vary.
