Phenergan-Codeine (codeine and promethazine) is used to treat cold or allergy symptoms such as runny nose, sneezing, and cough. Codeine is a narcotic that acts a pain reliever and a cough suppressant, and promethazine is an antihistamine. The brand name Phenergan-Codeine is no longer available in the U.S. Generic versions may be available. Common side effects include drowsiness, dizziness, headache, lightheadedness, blurred vision, upset stomach, nausea, constipation, increased sweating, or dry mouth.

The adult dose of codeine and promethazine is 1 tsp (5 ml) every 4 to 6 hours, not to exceed 30 ml in 24 hours. Pediatric dose is based on the child's weight. Codeine and promethazine may interact with sedatives or anxiety medicines, antidepressants, narcotics, phenobarbital, amobarbital, secobarbital, MAO inhibitors, atropine, belladonna, clidinium, dicyclomine, glycopyrrolate, hyoscyamine, methscopolamine, and scopolamine. Tell your doctor all medications you use. During pregnancy, this drug should be used only if prescribed. It is not recommended for use during the last 3 months of pregnancy due to increased risk for withdrawal symptoms such as irritability, abnormal/persistent crying, diarrhea, or seizures. Tell your doctor if you notice symptoms in your newborn. This product passes into breast milk and may rarely have undesirable effects on a nursing infant. Tell your doctor if your infant develops increased sleepiness, difficulty feeding, or trouble breathing. Consult your doctor before breast-feeding. The codeine in this medication may be habit-forming. Withdrawal symptoms may occur if you suddenly stop taking this drug.

SIDE EFFECTS: Drowsiness, dizziness, headache, lightheadedness, blurred vision, upset stomach, nausea, constipation, or dry mouth may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

This medication can dry up and thicken mucus in your lungs, making it more difficult to breathe and clear your lungs. To help prevent this effect, drink plenty of fluids unless otherwise directed by your doctor.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Seek immediate medical attention if any of these rare but very serious side effects occur: easy bruising/bleeding, slow heartbeat, persistent nausea/vomiting, severe abdominal pain, yellowing eyes/skin, seizure.

Codeine is changed into a strong narcotic drug (morphine) in your body. In some people, this change happens faster and more completely than usual, which increases the risk of very serious side effects. Get medical help right away if you notice any of the following: slow/shallow breathing, unusual drowsiness/difficulty waking up, confusion.

This medication may rarely cause a very serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, muscle stiffness/pain/tenderness/weakness, severe tiredness, severe confusion, sweating, fast/irregular heartbeat, dark urine, change in the amount of urine.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
