Urea/salicylic acid is a combination of two medications that are used to help promote healing of the skin and soften skin and nails. It's available with a prescription and over the counter (OTC). Urea/salicylic acid is typically applied to the skin or nails twice a day. Side effects include temporary stinging, burning, and irritation where it's applied.
Abnormally thick or tough skin or nails (hyperkeratosis)
Urea/salicylic acid is a combination of two medications.
Urea is an emollient. It helps loosen the outer layers of the skin and softens the skin and nails.
Salicylic acid is a keratolytic agent, meaning it breaks down the outer layer of your skin. This helps to treat conditions with abnormally thickened skin, such as calluses, corns, psoriasis, and eczema.

Urea/salicylic acid works best if you use it consistently. To get the most benefit from the medication, make sure to use it for as long as your provider tells you to.
Wash your hands after using urea/salicylic acid (unless you're applying it to your hands or fingernails). This will help you avoid getting it into your eyes.
If you develop a skin rash, any redness or irritation, or your condition becomes worse, stop using urea/salicylic acid and contact your healthcare provider.
Store urea/salicylic acid at room temperature and away from children and pets. If a child accidentally swallows urea/salicylic acid, contact a Poison Center at 1-800-222-1222 right away.

Make sure to apply urea/salicylic acid to the affected area(s) on your skin or nails only. Avoid getting it in your eyes, on your lips, or on other mucous membranes (e.g., inside of your nose, mouth, or vagina). This can lead to irritation and other side effects.
Urea/salicylic acid can sometimes cause stinging, burning, dryness, and irritation where you apply it. If you notice a rash, redness, or irritation, contact your provider. They can help you decide if you should still use this medication.
