Assessment⬆⬇
Assess location and number of lesions.
Assess for signs and symptoms of skin irritation or cutaneous reaction. If severe blistering, severe pain, or other severe reactions occur, remove cantharidin with soap and water. Provide supportive care. Treat pain with appropriate analgesia.
Implementation⬆⬇
All health care professionals should receive instruction and training prior to preparation and administration of cantharidin.
Cantharidin is for topical use only; it is not for oral, mucosal, or ophthalmic use.
Do not attempt to use a clogged or damaged applicator. Do not cut or modify the applicator in any way, as this could reduce dispensing control.
If any leaks or damage are observed to ampules, applicators, or break tools, discard in sharps container.
Topical Gloves and eye protection should be worn during preparation and administration. Gently tap capped end of the applicator on a horizontal surface for approximately 10 sec or until the solution has collected at the bottom of the applicator tube. Remove cap and gently squeeze the applicator tube to apply a droplet to a paper towel or gauze to confirm the applicator is working properly. Apply a small droplet of solution onto each molluscum lesion. Use the applicator tip to spread the solution to cover the entire lesion. Repeat until all lesions have been treated. Allow solution to completely dry (up to 5 min) before contacting healthy skin to avoid transference. Apply a single application directly to each lesion every 3 wk as needed; do not use more than two applicators during a single treatment session. Do not cover any treated lesions with bandages. Discard applicator in sharps container after use. Remove cantharidin with soap and water 24 hr after treatment. Avoid other topical products on treated areas until 24 hr after treatment.
