Canfree Ear Drop is an antifungal medication that treats ear infections. It works by killing the fungi in the ear by destroying their cell membrane. Canfree Ear Drop is for external use only. Take it in the dose and duration as advised by your doctor. Wash your hands before and after applying the medicine. Hold the dropper close to the ear without touching it. This medicine should be used regularly to get the most benefit from it. Do not stop using the medicine without a doctor consultation even if you feel better. You must consult with your doctor if the condition does not get improved within 2-4 weeks. It may cause irritation and ear discomfort immediately following the application. However, these side effects are temporary and usually subside on their own. Inform your doctor if they persist for a longer duration. Do not use the open bottle for more than 4 weeks. 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.
