What are the side effects of Codeine Phosphate and promethazine HCL?

Side effects of using Codeine Phosphate and promethazine HCL are not completely predictable and some are more common than others. You may become drowsy, dizzy, or disoriented, you may feel nauseous or constipated, and you may have blurry vision or feel anxious. Seek immediate medical attention if your skin or eyes become yellow, you have convulsions, or if you notice decreased urination, slow heartbeat, or uncontrolled shaking or muscle movement. You should also call your doctor if you have difficulty breathing, swelling, excessive sweating, hallucinations, or a change in blood pressure. Codeine products should not be given to children for pain relief after surgery to remove tonsils or adenoids, because there is a risk of severe respiratory depression or even death.
