Doctors recommend that parents of children younger than 12 years seek medical advice before giving aspirin to their children, WebMD states. However, children aged 2 to 11 usually take 10 to 15 milligrams orally every 4 to 6 hours, with no more than four doses in a 24-hour period. In general, patients who take aspirin must be aware of the dosage regulations and how to respond to missed doses and overdoses.
Aspirin is a nonsteroidal anti-inflammatory drug, or NSAID, and its uses vary between conditions. For example, children with juvenile rheumatoid arthritis take a larger dose than those suffering with a fever. As it is an NSAID, parents should consult with their doctor before administering other NSAIDs, including Ibuprofen.
It is important to take the dosage exactly as stated by a doctor, not in larger or smaller amounts. Parents who miss a dose should not double up; they should wait until the child's next dose to give it. If a child does take too much aspirin by accident, the parents should seek immediate emergency medical attention. Children may experience nausea, drowsiness, sickness and headaches when taking this drug. If they experience severe nausea, blood in the stools, hallucinations, ringing in the ears, an ongoing fever or swellings or pain that last longer than 10 days, they should seek immediate medical attention.
