Zocon Lotion belongs to a group of medicines called antifungals. It works by stopping the growth of fungus and is used to treat skin infections including infections of the fingernails and toenails. It kills fungi by destroying the fungal cell membrane. Zocon Lotion is for external use only. You should use it in the dose and duration as advised by your doctor. The affected area should be clean and dry before application of the medicine. Wash your hands before and after applying the medicine. If you have athlete’s foot, wash your socks or tights thoroughly and change your shoes daily if possible. Tell your doctor if the infection does not get better or if it gets worse. Some of the common side effects include skin irritation, redness, or itching at the site of application. Please consult your doctor if these side effects persist for a longer duration. Avoid direct contact with your eyes. In case of direct contact, wash your eyes with water and seek immediate medical attention. You should stop taking it straight away if you have any signs of an allergic reaction or of congestive heart failure. Signs of this include rash, swelling of the lips, throat or face, swallowing or breathing problems, feeling dizzy or faint, and nausea. It is not likely that other medicines you take by mouth or injection will affect the way this medicine works, but talk to your doctor before using it if you have recently used another medicine that contains a steroid or had an allergic reaction to another antifungal medicine. This medicine should only be used if it is clearly needed if you are pregnant or breastfeeding. Ask your doctor if it is safe.
