The recommended dosage of pseudoephedrine for children 6 to 11 years old is 30 mg. It is recommended that children four to five years old take 15 mg. For immediate-release tablets, the usual recommended dose for adults and children ages 12 and older is two tablets. For most forms of the drug, doses are typically taken every four to six hours.
The recommended dose of pseudoephedrine will vary, depending on a number of factors, including:
- Your age
- The particular product
- Other medications you are taking
- Other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.
(It should be noted that many pseudoephedrine products also contain other active ingredients. This article focuses on the recommended dosage of just pseudoephedrine, not such combination products.)
