Be Aware

Opioids can slow breathing and suppress the cough reflex. Before taking an opioid, tell your doctor if you have a history of lung disease or breathing difficulties. Taking opioids with certain other drugs can increase the risk of dangerous side effects. Especially tell your doctor if you take antihistamines (allergy medications), tranquilizers, sleeping pills, muscle relaxants or other pain medication, or if you have a history of alcohol or drug abuse.
