In deciding to use a medicine, you and your doctor need to consider the risks and benefits of taking it. The following points should be taken into account:

Allergies

Inform your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also, let your healthcare professional know about any other allergies you have, such as to foods, dyes, preservatives, or animals. For non-prescription products, carefully read the label or package ingredients.

Pediatric

Young children may be more likely to experience unwanted effects due to increased absorption of salicylic acid through the skin. Products containing salicylic acid should not be applied to large areas of the body or used for long periods of time in infants and children.

Therefore, it may not be known if they work the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing the use of salicylic acid and sulfur combination in the elderly with other age groups.
