How to use gel

Adults only:

  • Clean and dry the affected skin area and the surrounding skin area and then wash your hands.
  • Remove the cap and if this is your first time using gel , use the end of the cap to perforate the mouth of the tube.
  • Gently apply a large amount of gel that is applied over the entire affected area and the surrounding skin area in a thin layer.
  • Gently massage gel one into the skin.
  • Close the cap on the tube.
  • Wash your hands after using the gel, otherwise there is a risk that you will spread the infection to other parts of the skin or to other people.

If you are treating an infection in any fold of skin on your body, you can cover the treated area with gauze, especially at night. If you do, take a new, clean gauze pad each time you apply gel one.

Use gel one during the recommended treatment time even if infection one seems to be better after a few days. Infection usually gets better within a few days but it can come back if the gel is not applied regularly or if the treatment is stopped too soon. The skin infection usually gets better within a few days.

Unused gel should be discarded no later than 16 weeks after first opening.

Facilitate the treatment

Keep the affected skin area clean by washing it regularly. Pat the skin dry carefully but without rubbing.

Try not to scratch the area even if it itches. It can lead to further damage and delay the healing process or spread the infection one.

Because these infections can be transmitted to other people, use your own towel and clothes and do not share them with others. These should be washed frequently to protect you from a new infection .

If you forget to take Lamisil Dermgel

If you forget to apply gel one, do so immediately when you notice it and then continue as normal. If you notice it at the time of your next treatment, then apply a normal amount of gel and continue the treatment as usual. Use gel one according to the instructions. This is important because missed treatment sessions increase the risk of recurrence of the infection .
