Canthacur Solution is a topical solution made up of cantharidin; a vesicant. This medication is available in 0.70% doses.
Canthacur Solution is used to treat warts. Anyone can develop warts, they are contagious. There are many different types of warts such as; common, flat, facial, body, genital & plantar warts. A wart is a small growth on the skin with a rough texture and can appear anywhere on the body. The appearance of warts depends on where it is located on the body and the state of the skin (thickness). Some warts look like a solid blister where others look like a small cauliflower. Warts are caused by viruses in the HPV (human papillomavirus: a viral infection passed through skin contact) family.
This solution works by forming a blister underneath the wart; the blister eventually pops and takes the wart with it when it does.

What is the healing process of this medication?
After a few hours have passed since you washed it off, you may have slight discomfort. After 24 hours of applying the solution, you should have a fully formed blister (don’t be alarmed if you notice blood inside the blister). By day 4, the blister should be crusted, and falling off; this will leave the area red and raw-looking, you can apply Vaseline twice a day to help with the process. After a week it should be healed, possibly with slight redness still.
Does this treatment hurt?
