Penlac Nail Lacquer is a topical medical solution made up of an antifungal drug called ciclopirox. We carry the brand choice of this medication in 8%!

Penlac Nail Lacquer is used to treat fungal infections of the fingernails and toenails (onychomycosis). This medication makes up half the treatment; the other half of treatment includes the removal of unattached, infected nails by a professional health care provider as often as once a month. Symptoms of onychomycosis include yellow nail discoloration, thickening of the nail, and separation of the nail from the nail bed. These infections are caused when fungi invades a damaged fingernail or toenail.

Penlac Nail Lacquer (ciclopirox) is effective at treating fungal infections of the finger/toenails because it is able to prevent the fungus from growing further, so the immune system can heal the infection and remove the fungi much quicker and easier.

Penlac Nail Lacquer (ciclopirox) should be taken exactly the way your doctor has prescribed it to you. Do not use more or less of this medication and do not stop using it unless directed to by your doctor.

Use this product on the nails and surrounding skin once a day, while avoiding contact with other areas. Apply this medication with the applicator brush provided. Apply an even layer over the entire nail. If possible, apply the nail lacquer to the underside of the nail and to the skin below it. Allow the medicine to dry for 30 seconds before putting on socks or stockings. After applying, wait 8 hours before taking a shower or bath. Apply the medicine over top of the previous coat. At the end of the week, remove the nail lacquer with alcohol and remove any damaged nails using nail clippers or a nail file.
