Case scenario 

John, 33, presents to your pharmacy. He’s just been to see the doctor because the edge of his toenail looks yellow and thick. He explains that the problem started a few months ago after he joined a gym and started using the gym’s shower facilities to get ready for work. The doctor advised him to use a topical nail antifungal treatment and to come back for a review in a couple of months. John asks for your recommendation and for any additional advice.
