Uses for Thera-Sal

Salicylic acid topical is used to treat many skin disorders, such as acne, dandruff, psoriasis, seborrheic dermatitis of the skin and scalp, calluses, corns, common warts, and plantar warts, depending on the dosage form and strength of the preparation.

This medicine is available without a prescription. Some of these preparations are available only with your doctor's prescription.

Before using Thera-Sal

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Young children may be at increased risk of unwanted effects because of increased absorption of salicylic acid through the skin. Also, young children may be more likely to get skin irritation from salicylic acid. Salicylic acid should not be applied to large areas of the body, used for long periods of time, or used under occlusive dressing (air-tight covering, such as kitchen plastic wrap) in children. Use of salicylic acid topical in children younger than 2 years of age is not recommended.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of salicylic acid topical in the elderly. However, elderly patients are more likely to have age-related blood vessel disease, which may require caution in patients receiving salicylic acid topical.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
