Nubain : Narcotic (nar-KOT-ik) analgesics (an-al-JEE-zicks) are used to relieve pain. Some of these medicines are also used just before or during an operation to help the anesthetic work better. Codeine and hydrocodone are also used to relieve coughing. Methadone is also used to help some people. Phenergan is an antihistamine. It blocks the effects of the naturally occurring chemical histamine in your body. Phenergan is also used to cause sedation (sleep), to assist in controlling postoperative pain, to control nausea and vomiting (especially after surgery), and to prevent motion sickness.
