Instructions for care after treatment with cantheridin
Your skin had been treated with cantheridin (Canthecur). Cantheridin (from the blister beetle) produces a localized blistering of the skin only where treated.
What to expect after treatment:
*The treated areas need to be washed with soap and water in four (4) hours or sooner if lesions start to blister or there is pain. The area/s may be tender for several days.
* It is normal for the areas/s to be red and possibly blister or erode over the next few days.
* You may get the area/s wet and continue your normal daily activities. If the blisters are large or cause a problem, please call the office. If the blisters break or crusting occurs, cover it with Vaseline and a band-aid and change daily until it heals (approximately 7 days).
