Yes, a pharmacist can recommend over-the-counter products for nail fungus, but they may not be very effective. For a more potent treatment, you would need a prescription from a doctor or podiatrist for medications like Jublia, Ciclopirox, or terbinafine. In addition to medication, practicing good foot hygiene can help prevent the spread of nail fungus, such as wearing cotton socks, keeping shoes and socks clean, drying feet thoroughly, wearing sandals in public places, keeping nails clean and short, avoiding sharing nail clippers and shoes, bringing your own tools to the salon, preventing nail trauma, and applying moisturizers to cracked skin.
