1. What ONYTEC is and what it is used for

Onytec contains the active substance ciclopirox, which belongs to a group of medicines known as antifungals. It kills a wide range of fungi that can cause nail infections.

Onytec is used to treat mild to moderate fungal infections of the nails without nail matrix/lunula (white half-moon of the nail) involvement in adults.

Driving and using machines

Onytec has no influence on the ability to drive and use machines.

Onytec contains alcohol (ethanol)

This may cause a burning sensation on damaged skin.

3. How to use ONYTEC

Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Onytec should only be used on the infected nails and the skin immediately around them. Onytec is for use in adults only.

Instructions for use:

Step 1: Before each application of Onytec carefully wash and dry the nails. Step 2: Using the applicator, apply a thin layer once a day to each of the infected nail/s. The medicated nail lacquer should be applied over the entire nail surface and 5 mm of surrounding skin. If possible, Onytec should be applied also under the free edge of the nail.

Step 3: Wait about 30 seconds until the lacquer has completely dried before doing any activity.

Do not wash the nails for at least 6 hours. For this reason it is recommended to apply Onytec, in the evening before going to bed. After that time, normal hygienic practices can be followed. In case you accidentally remove it by washing, you can apply it again.

Onytec does not need to be removed by any solvent or abrasives (i.e. nail filing), it is sufficient to wash the nails with water. You should regularly remove unattached parts of the infected nail, e.g. by clipping the nails.
