How it works

Cantharidin causes acantholysis by disrupting desmosomal connections in epidermal cells, resulting in blister formation that lifts and removes the lesion.

Side Effects

Common adverse effects include localized blistering, erythema, pain, burning, swelling, and temporary post-inflammatory pigmentation changes.

Storage

Store at room temperature (68–77°F / 20–25°C). Do not refrigerate or freeze.

Pregnancy Information

Not indicated for use during pregnancy.

Drug Interactions

No significant systemic interactions are known, but concurrent use with other topical wart therapies or irritants may increase local skin irritation.
