Cantharone Plus Liquid (Cantharidin/Salicylic Acid/Podophyllin) from Maple Leaf Medications.

What is Cantharone Plus used for? 

Cantharone Plus, with the chemical name cantharidin, salicylic acid, and podophyllin, is a topical liquid used to treat plantar warts caused by viruses. This condition occurs when the virus infects the basal layer of the skin.  

This medication can reduce the thickness of treatment-resistant warts and can also be used for warts under or around the nail. 

This topical product is available in Cantharone Plus 1/30/2% in 7.5 mL and 15 mL bottles.

How does Cantharone Plus work? 

This drug primarily works by forming a blister underneath the wart. Forming a blister leads to the killing of the wart as it cuts the blood supply.  

Cantharone Plus application is usually painless, although blisters can cause pain, itch, inflammation, and fluid.
