Available Dosage Forms:
Therapeutic Class: Antitussive, Opioid/Antihistamine/Decongestant Combination
Pharmacologic Class: Phenylephrine
Chemical Class: Codeine
Uses For codeine, phenylephrine, and promethazine
Codeine, phenylephrine, and promethazine combination is used for the temporary relief of cough, runny or stuffy nose, sneezing, or other symptoms caused by allergies or the common cold.
Codeine belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain. Phenylephrine is a decongestant. It works by narrowing the blood vessels and leads to the clearing of nasal congestion.
Promethazine is an antihistamine. It works by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. It can sometimes close up the bronchial tubes (air passages of the lungs) and make breathing difficult.
When codeine is used for a long time or in large doses, it may become habit-forming, causing mental or physical dependence. Physical dependence may lead to withdrawal side effects when you suddenly stop taking the medicine.
Codeine, phenylephrine, and promethazine is available only with your doctor's prescription.
Before Using codeine, phenylephrine, and promethazine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For codeine, phenylephrine, and promethazine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to codeine, phenylephrine, and promethazine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Use of Promethazine VC with codeine oral liquid in children and Promethazine, phenylephrine, and codeine oral solution in children younger than 12 years of age is not recommended.
It should not be used to relieve pain after surgery to remove tonsils or adenoids in any children. Severe breathing problems and deaths have been reported in some children who received codeine after tonsil or adenoid surgery.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of codeine, phenylephrine, and promethazine combination in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving codeine, phenylephrine, and promethazine combination.
Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using codeine, phenylephrine, and promethazine.

Proper Use of codeine, phenylephrine, and promethazine
Take codeine, phenylephrine, and promethazine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of codeine, phenylephrine, and promethazine is taken for a long time, it may become habit-forming (causing mental or physical dependence).
Measure the oral liquid with a marked measuring spoon, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid.
Codeine, phenylephrine, and promethazine should come with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.
The dose of codeine, phenylephrine, and promethazine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of codeine, phenylephrine, and promethazine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
- For symptoms of cough or stuffy nose caused by allergies:
- For oral dosage forms (elixir or syrup):
- Adults—5 milliliters (mL) every 4 to 6 hours as needed. Do not take more than 30 mL in 24 hours.
- Children—Use is not recommended.
- For oral dosage form (syrup):
- Adults and children 12 years of age and older—5 milliliters (mL) or 1 teaspoonful every 4 to 6 hours. Do not take more than 30 mL in 24 hours.
- Children younger than 12 years of age—Use is not recommended.
- For oral dosage forms (elixir or syrup):
If you miss a dose of codeine, phenylephrine, and promethazine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
Precautions While Using codeine, phenylephrine, and promethazine
It is very important that your doctor check your or your child's progress while using codeine, phenylephrine, and promethazine. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to take it. Blood tests may be needed to check for unwanted effects.
If your or your child's symptoms (eg, cough) do not improve or become worse within 5 days, check with your doctor right away.
Do not use codeine, phenylephrine, and promethazine if you or your child is using or has used an MAO inhibitor (MAOI) such as isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.
Codeine is changed to morphine in the body. Some people change codeine to morphine more quickly than others. These individuals are called "ultra-rapid metabolizers of codeine". Contact your doctor immediately if you have extreme drowsiness, sleepiness, confusion, or shallow breathing. These symptoms may indicate that you are an "ultra-rapid metabolizer of codeine". As a result, there is too much morphine in the body and more side effects of morphine than usual. Children may be especially sensitive to this effect. Do not give codeine, phenylephrine, and promethazine to:
- Children younger than 12 years of age.
- Children younger than 18 years of age who have had surgery removal of tonsils or adenoids.
- Children 12 to 18 years of age who have a high risk for breathing problems (eg, obstructive sleep apnea, obesity, lung disease).
If a nursing mother is an ultra-rapid metabolizer of codeine, it could lead to morphine overdose in the nursing baby and cause very serious side effects.
For nursing mothers taking codeine, phenylephrine, and promethazine:
- Talk to your doctor if you have any questions about using codeine or about how codeine, phenylephrine, and promethazine may affect your baby.
- Call your doctor if you become extremely tired and have difficulty caring for your baby.
- Your baby should generally nurse every 2 to 3 hours and should not sleep for more than 4 hours at a time.
- Check with your doctor, hospital emergency room, or local emergency services (eg, "call 9-1-1") immediately if your baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, difficulty breathing, or limpness. These may be symptoms of an overdose and need immediate medical attention.
Using codeine, phenylephrine, and promethazine while you are pregnant may cause serious unwanted effects, including neonatal opioid withdrawal syndrome in your newborn baby. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using codeine, phenylephrine, and promethazine.
If you think you or someone else may have taken an overdose of codeine, phenylephrine, and promethazine, get emergency help at once. Signs of an overdose include: dark urine, difficult or troubled breathing, irregular, fast or slow, or shallow breathing, nausea, vomiting, pain in the upper stomach, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, or yellow eyes or skin.
Codeine, phenylephrine, and promethazine will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of these medicines while you or your child are using codeine, phenylephrine, and promethazine.
Codeine, phenylephrine, and promethazine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives or stool softeners, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.
Codeine, phenylephrine, and promethazine may make you dizzy, drowsy, or less alert than they are normally. Do not drive or do anything else that could be dangerous until you know how codeine, phenylephrine, and promethazine affects you.
Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help. Also, lying down for a while may relieve dizziness or lightheadedness.
Promethazine may increase your risk for convulsions (seizures). It may also cause dystonia (movement disorder). This is more likely in sick children with diarrhea. Talk to your doctor if you have any concerns.
Check with your doctor right away if you or your child are having convulsions, difficulty with breathing, fast heartbeat, high fever, high or low blood pressure, increased sweating, loss of bladder control, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
Codeine, phenylephrine, and promethazine may cause adrenal insufficiency. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.
If you are especially sensitive to the effects of codeine, phenylephrine, and promethazine, do not suddenly stop using it without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help reduce the possibility of withdrawal symptoms, such as abdominal or stomach cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble sleeping.
Using too much of codeine, phenylephrine, and promethazine may cause infertility (unable to have children). Talk with your doctor before using codeine, phenylephrine, and promethazine if you plan to have children.
Make sure any doctor or dentist who treats you knows that you are using codeine, phenylephrine, and promethazine. You or your child may need to stop using codeine, phenylephrine, and promethazine several days before you have surgery or medical tests.
Codeine, phenylephrine, and promethazine may make your skin more sensitive to sunlight. Use sunscreen when you are outdoors. Avoid sunlamps and tanning beds.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
