Chemergan VC with Codeine Oral Warning

The promethazine in this combination medication should not be used in children younger than 2 years due to an increased risk for serious (rarely fatal) slow/shallow breathing (respiratory depression). This infrequent side effect may occur even with usual prescribed doses of promethazine. The lowest effective dose should be used, and other drugs that may slow down breathing should be avoided. Some manufacturers recommend that promethazine and other drugs that may also slow down breathing (e.g., the codeine in this product) should not be used together in children younger than 16 years. Seek immediate medical attention if you notice symptoms of slow/shallow breathing.
