Before using sodium thiosulfate
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 sodium thiosulfate, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to sodium thiosulfate 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.
Although there is no specific information comparing use of sodium thiosulfate in children with use in other age groups, sodium thiosulfate is not expected to cause different side effects or problems in children than it does in adults.

Interactions with food/tobacco/alcohol
