WARNING: Promethazine should not be used in children younger than 2 years since it might cause slow/shallow breathing (respiratory depression), which in some cases could be fatal. This problem has occurred even with normal doses in this age group.
Use this drug with caution in children older than 2 years. The lowest effective dosage should be used, and other drugs that affect breathing should be avoided. Seek immediate medical attention in the unlikely event that slow/shallow breathing occurs.
This medication can cause severe tissue damage, possibly requiring surgery. Tell your doctor/nurse immediately if you experience burning, pain, redness, swelling, or numbness at or near the injection site. If this occurs, the injection should be stopped and the injection site checked.
It is preferred that this medication be given by injection into a muscle. There may be an increased risk of side effects if this medication is given by injection into a vein. This medication must not be given by injection under the skin.
