Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
This medication is used to treat fungal infections of the fingernails and toenails. It is used as part of a treatment program that includes the removal of unattached, infected nails by a health care professional as frequently as once a month. Ciclopirox works by stopping the growth of fungus.
How To Use
Read the Patient Information Leaflet if available from your pharmacist before you start using ciclopirox and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Before starting treatment, remove any loose nail material using nail clippers or a file. If you have diabetes or numbness in your fingers/toes, talk to your doctor before filing or trimming your nails. It may be safer for your doctor to file or remove your nails.
Use this medication on the nails and skin next to the nails only. Apply ciclopirox as directed by your doctor, usually once daily at bedtime. Using the applicator provided, apply this medication evenly over the entire affected nail and to the area of the skin next to the nail (5 millimeters or 1/5 of an inch around the nail). If the applicator can reach the undersurface of the nail and the skin under the nail, apply the medication to those areas as well. Avoid contact with skin that is not right next to the affected nail. Do not use nail cosmetic products (such as nail polish) on the treated nails.
Do not apply the medication in the eyes, nose, or mouth, or inside the vagina. If you do get the medication in those areas, rinse with plenty of water.
Let the medication dry (around 30 seconds) before putting on socks or stockings. Do not wash the treated area for at least 8 hours.
Every 7 days, remove the medication from the nail by applying alcohol. Then trim the nail and file away any loose nail material.
Since this product is flammable, do not use this product near heat or open flame.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day.
Continue to use this medication for the full time prescribed, even if symptoms disappear. Stopping the medication too early may result in a return of the infection.
Tell your doctor if your condition worsens or does not improve after 6 months of treatment. It may take up to one year for the nail to be clear or almost clear.
Redness/burning of treated skin or changes in shape/color of nail may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
