Method of administration

Ledaga® is for topical application to the skin.

The following instructions should be followed by patients or caregivers when applying Ledaga®:

  • Patients must wash hands thoroughly with soap and water immediately after handling or applying Ledaga®. Patients should apply Ledaga® to affected areas of the skin. In case of Ledaga exposure to non-affected areas of the skin, patients should wash the exposed area with soap and water.

  • Caregivers must wear disposable nitrile gloves when applying Ledaga® to patients. Caregivers should remove gloves carefully (turning them inside out during the removal to avoid contact with Ledaga®) and wash hands thoroughly with soap and water after removal of gloves. If there is accidental skin exposure to Ledaga, caregivers must immediately wash exposed areas thoroughly with soap and water for at least 15 minutes. Remove and wash contaminated clothing.

  • The opening of the tube is covered with a foil safety seal. The cap should be used to puncture the seal. The tube should not be used and the pharmacist should be contacted if the seal is missing, punctured, or lifted.

  • Ledaga® should be applied immediately or within 30 minutes after removal from the refrigerator. The tube should be returned to the refrigerator immediately after each use. With clean hands, the tube should be placed back into the original box and the box should be placed in the supplied transparent, sealable, plastic bag for storage in the refrigerator.

  • Ledaga® should be applied to completely dry skin at least 4 hours before or 30 minutes after showering or washing. The patient should allow treated areas to dry for 5 to 10 minutes after application before covering with clothing. Occlusive (air- or water-tight) dressings should not be used on areas of the skin where Ledaga was applied.

  • Emollients (moisturisers) or other topical products may be applied to the treated areas 2 hours before or 2 hours after application of Ledaga®.

  • Fire, flame, and smoking must be avoided until Ledaga® has dried.
