This product contains 2 main ingredients. Salicylic acid is a keratolytic. It belongs to the same class of drugs as aspirin (salicylates). It works by breaking down the thick top layer of skin and increasing the amount of moisture in the skin. It causes the wart, corn, or callus to gradually peel off. Flexible collodion works by forming a protective coating over the treated area. It helps to keep the area clean and also keeps the salicylic acid and moisture in contact with the skin.
If you are self-treating with this medication, it is important to read the package instructions carefully before you start using this product to be sure it is right for you. (See also Precautions section.)
Use this product on the skin as directed by your doctor. If you are self-treating, follow all directions on the product package. If you are uncertain about any of the information, ask your doctor or pharmacist.
First wash the affected area. You may soak it in warm water for about 5 minutes to soften it. Dry thoroughly. Your doctor may direct you to use a rough towel, pumice stone, callus file, or emery board to gently remove the top dead layers of thickened skin after soaking and before applying the liquid. Do not use sharp objects. Removing the dead skin helps the medication to work better. Do not try to rub the wart, corn, or callus off.
Using the applicator provided, apply a thin coat of the medication (one drop at a time) to cover the entire wart, corn, or callus. To minimize irritation, be careful not to get the liquid on surrounding skin. Let dry. Repeat this procedure 1 to 2 times daily as needed until the wart, corn, or callus is removed. For warts, you may use this product for up to 12 weeks. For corns and calluses, you may use it for up to 2 weeks. Wash hands after use.
Do not use this product on skin that is irritated, red, or infected. Avoid contact with the eyes and face. If this product gets on these areas or on healthy surrounding skin, wash it off right away. Flush the eyes with water for 15 minutes. If irritation persists, contact your doctor right away.
Do not apply a large amount of this medication or apply it to a large area. Do not use it more often or for longer than directed. Your condition will not improve any faster, and your risk of side effects will increase.
