Children are more sensitive than adults to many drugs.
Antihistamines and alcohol, for example, two common ingredients in cold medications, can have adverse effects on young patients, causing excitability or excessive drowsiness. Some drugs, like aspirin, can cause serious illness or even death in children with chickenpox or flu symptoms. Both alcohol and aspirin are present in some children's medications and are listed on the labels. The younger the child, the trickier using medicine is. Prescription drugs, also, can work differently in children than adults.
