Promethazine hydrochloride/phenylephrine hydrochloride/codeine phosphate use is contraindicated in pediatric patients under 6 years of age. Concomitant use of promethazine products with respiratory depressants has an association with respiratory depression, and sometimes death, in pediatric patients. Postmarketing cases of respiratory depression, including fatalities, have been reported with a wide range of weight-based promethazine doses in pediatric patients younger than 2 years. Respiratory depression and death have occurred in children who received codeine following tonsillectomy or adenoidectomy and had evidence of being ultrarapid metabolizers of codeine due to CYP2D6 polymorphism. Concomitant use of benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, or death. Avoid concomitant use .

Uses For Promethazine VC With Codeine
Codeine, phenylephrine, and promethazine combination is used to treat for the temporary relief of cough or stuffy nose 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 clearing of the 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 stop taking the medicine.
This medicine is available only with your doctor's prescription.
Before Using Promethazine VC With Codeine
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 this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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 codeine, phenylephrine, and promethazine combination in children younger than 6 years of age is not recommended. It should not be used to relieve pain after the surgical removal of tonsils and/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.

Precautions While Using Promethazine VC With Codeine
It is very important that your doctor check your progress while you or your child are using this medicine. 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.
If your or your child's symptoms do not improve or become worse, check with your doctor right away.
Do not use this medicine if you or your child is also using an MAO inhibitor (such as Eldepryl®, Marplan®, Nardil®, or Parnate®).
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.
If a nursing mother is an ultra-rapid metabolizer of codeine, it could lead to a morphine overdose in the nursing baby and cause very serious side effects.
For nursing mothers taking this medicine:
- Talk to your doctor if you have any questions about taking codeine or about how this medicine 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 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.
If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Signs of an overdose include dark urine, difficult or troubled breathing, irregular, fast or slow, or shallow breathing, nausea or vomiting, pain in the upper stomach, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, or yellow eyes or skin.
This medicine 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 this medicine.
This medicine 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.
This medicine may make you dizzy or drowsy. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
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).
Make sure any doctor or dentist who treats you knows that you are using this medicine. You or your child may need to stop using this medicine several days before you have surgery or medical tests.
This medicine may make your skin more sensitive to sunlight. Use a 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.
