Some medicines which contain pseudoephedrine can be taken by children over the age of 6, such as Sudafed Decongestant Liquid.
However, every medication can have different age restrictions, especially those where pseudoephedrine is used alongside other active ingredients, so be sure to check that the medicine is right for your child before giving it to them.
If you’re unsure about the age limitations on any medication, speak to your doctor or pharmacist before giving the product to your child.
