Important warnings
This medicine can cause some serious health issues
Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.

Serious, life-threatening side effects can occur if you take cold medicine before the MAO inhibitor has cleared from your body.
Do not use any other over-the-counter cough, cold, allergy, or sleep medication without first asking your doctor or pharmacist.
