Medicare Fungal Nail Pen is a medical device that is used for fungal nail treatment. It improves the appearance of the nail and reduces discolouration. In most patients, the results are visible within 2 weeks*. Optimal results are obtained when used daily until the healthy nail has grown out. The solution contained in the pen applicator creates an environment such that the fungus is not able to survive or multiply. After one week of application, visible improvement can be seen.
