What is Promethazine with Codeine?
Codeine is a narcotic. It is a pain reliever and a cough suppressant. Promethazine is an antihistamine. It blocks the effects of the naturally occurring chemical histamine in your body.
Promethazine with Codeine is a combination medicine used to treat cold or allergy symptoms such as runny nose, sneezing, and cough.
Promethazine with Codeine may also be used for purposes not listed in this medication guide.
Promethazine with Codeine is not for use in anyone under 18.
Taking this medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use this medicine if you are allergic to codeine or promethazine, or if you have asthma, pneumonia, or other lung problems.
In some people, codeine breaks down rapidly in the liver and reaches higher than normal levels in the body. This can cause dangerously slow breathing and may cause death, especially in a child.
Do not give this medicine to anyone younger than 18 years old.
To make sure Promethazine with Codeine is safe for you, tell your doctor if you have ever had:
drug or alcohol addiction;
severe or ongoing cough;
a blood cell disorder;
liver or kidney disease;
a thyroid disorder;
an enlarged prostate, urination problems;
Addison's disease (an adrenal gland disorder); or
surgery on your stomach or urinary tract.
If you use codeine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Do not breast-feed. Codeine can pass into breast milk and may cause drowsiness, breathing problems, or death in a nursing baby. Do not breast-feed. Antihistamines may also slow breast milk production.
How should I take Promethazine with Codeine?
Follow all directions on your prescription label. Promethazine with Codeine can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Cough or cold medicine is usually taken only for a short time until your symptoms clear up.
Codeine may be habit-forming, even at regular doses. Never share Promethazine with Codeine with another person, especially someone with a history of drug abuse or addiction.

Selling or giving away codeine is against the law.

Call your doctor if your symptoms do not improve after 5 days of treatment.

Keep track of your medicine. Promethazine with Codeine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A codeine overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include slow breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, pinpoint pupils, and fainting.
