nail(s) dry for approximately 3 minutes.
(Fig. 6)

Do not use nail files used for infected nails on healthy nails,
otherwise you may spread the infection. To prevent the spread of
infection take care that no one else uses the files from your kit.
The spatulas provided are re-usable. However, it is important to
clean them thoroughly after completing each treatment
procedure, using the same swab you used for nail cleansing.
Avoid touching newly treated nails with the swab. Close the
nail lacquer bottle tightly. Dispose of the swab carefully as it is
• Before using Clavusimyl again, first remove the old lacquer
from your nails using a swab, then file down the nails again if
• Re-apply the lacquer as described above.
• When dry the nail lacquer is unaffected by soap and water, so
you may wash your hands and feet as normal. If you need to
use chemicals such as paint thinners or white spirit, rubber or
other impermeable (waterproof ) gloves should be worn to
protect the lacquer on your fingernails.
• It is important to carry on using Clavusimyl until the infection
has cleared and healthy nails have grown back. This usually
takes 6 months for finger nails and 9 to 12 months for toe nails.
Your doctor will probably check how your treatment is
progressing every 3 months or so.
If you get Clavusimyl in your eyes or ears
If you get Clavusimyl in your eyes or ears wash out with water
immediately and contact your doctor, pharmacist or nearest
hospital straight away.
If you accidentally swallow Clavusimyl
If you, or anyone else, accidentally swallows the lacquer contact
your doctor, pharmacist or nearest hospital straight away.
If you forget to use Clavusimyl
Don't worry if you forget to use Clavusimyl at the right time.
When you remember, start using the product again, in the same
way as before.
If you stop using Clavusimyl
Do not stop using Clavusimyl before your doctor tells you to or

If you have any further questions on the use of this medicine, ask
your doctor or pharmacist.
