Is cantharidin legal in the US?
Although not approved by the United States Food and Drug Administration, cantharidin has been available through a variety of compounding sources without standardization of manufacturing, formulation, or method of application.
When can I wash off cantharidin?
Cantharidin is a vesicant, which means it causes the skin to blister. It is applied to a wart, which is then covered by a bandage or tape. You should remove the Band-Aid and wash the area with soap and water after about 6 hours. Over the next 12-24 hours, it may cause the skin to blister.
Can you swim after cantharidin treatment?
Some discoloration of the skin can occur after treatment. However, there is no resultant scarring. No special care is required after treatment. The patient may bathe, swim, etc.
How long does it take cantharidin to work?
Topical cantharidin treatment causes formation of blisters within 24 to 48 hours. Healing is complete 4 to 7 days after application. Patients will typically feel a tingling or burning sensation within a few hours of application.
How long do you leave cantharidin on?
Cantharidin (formulated with substances that create an oily or colloidal film) is accurately applied to the wart or molluscum. The liquid is allowed to dry and then covered and sealed with nonporous tape for 4–6 hours. The tape should then be removed and the area washed with soap and water.
How much does cantharidin cost?
On average, children have about 15-30 lesions by the time a family seeks treatment. Liquid nitrogen costs $50 per patient for supplies; Cantharidin, an extraction from blister beetles, is a topical vesicant that costs about $100.
Do I pop a wart blister?
It is best to leave the blister alone and allow it to dry. If the blister is painful you may pop it.
How long does it take for cantharidin blisters to heal?
Topical cantharidin treatment causes formation of blisters within 24 to 48 hours. Healing is complete 4 to 7 days after application.
Should I pop a blister beetle bite?
Mild reactions don’t require treatment and will heal on their own, though popping blisters can lead to infection. If you touch a blister beetle, wash your hands and don’t rub your eyes. If you do, seek medical attention immediately.
Why is my wart blistering?
In most cases a blister will form where liquid nitrogen is applied. The location of the wart and the thickness of the skin around the wart will determine how long it takes for the blister to form. The blister may be either clear or filled with blood. Sometimes a crust or scab may form instead.
Is it bad to rip a wart off?
Absolutely not. Filing, ripping, picking, burning, or cutting a wart on your own will most often make the presence of warts even worse on the foot and potentially on other skin areas of the body. This can result in infection or further spreading of the warts. The wart will either get larger or more numerous.
What happens if you scratch a wart off?
Don’t rub, scratch, or pick at the wart. Doing so could spread the virus to another part of your body or cause the wart to become infected.
