Who should not use salicylic acid?

Salicylic acid is not recommended for children under two years of age. Children and adolescents with influenza or chicken pox should also avoid using salicylic acid products because of an increased risk of Reye's syndrome. People with allergies to salicylic acid or related medicines, such as aspirin, should talk to their doctor before using preparations made with salicylic acid. Pregnant women, breastfeeding women and women who are planning a pregnancy also should talk with their doctor before starting a salicylic acid regimen. Similarly, check with your doctor if you are diabetic, have experienced kidney or liver disease or poor circulation.
