Itchderm 1% Dusting Powder is an antifungal medication. It is used in the treatment of fungal skin infections such as ringworm, athlete’s foot, nappy rash, sweat rash, and vaginal thrush. It kills the fungi by destroying the fungal cell membrane. Itchderm 1% Dusting Powder is for external use only. You should use it in the dose and duration advised by your doctor. This medicine should be used regularly to get the most benefit from it. Do not use more than you need as that may cause increased side effects. If your condition goes on for longer than four weeks or gets worse at any time, let your doctor know. The effects of this medicine can be increased by keeping the affected area clean and dry and washing hands before and after treating the infection. If you have an athlete’s foot, wash your socks or tights thoroughly and change your shoes daily if possible. Some of the common side effects include skin irritation, redness, or itching at the site of application. If the side effects bother you or do not go away, let your doctor know. Some people have a severe allergic reaction that needs urgent medical attention. Signs of this include rash, swelling of the lips, throat, or face, swallowing or breathing problems, dizziness and nausea. Get emergency help if this happens. It is not likely that other medicines you take by mouth or injection will affect the way it works but talk to your doctor before using it if you have used a similar medicine before and had an allergic reaction. This medicine should only be used if it is clearly needed during pregnancy.
