What is Iophen-C NR (codeine and guaifenesin)?

Codeine is a narcotic cough suppressant. It affects the signals in the brain that trigger cough reflex.

Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.

Codeine and guaifenesin is a combination medicine used to treat cough and chest congestion caused by allergies, the common cold, or the flu.

This medicine will not treat a cough that is caused by smoking, asthma, or emphysema.

Codeine and guaifenesin may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking Iophen-C NR (codeine and guaifenesin)?

You should not take this medicine if you are allergic to codeine or guaifenesin.

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.

Ask a doctor before giving this medicine to a child younger than 12 years old.

Medicines that contain codeine should not be used in anyone under 18 who recently had surgery to remove the tonsils or adenoids.

To make sure codeine and guaifenesin is safe for you, tell your doctor if you have ever had:

  • a cough with mucus;

  • asthma, COPD, or other breathing disorder;

  • blockage in your digestive tract (stomach or intestines);

  • a head injury or brain tumor;

  • low blood pressure; or

  • drug or alcohol addiction.

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.

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.

What should I avoid while taking Iophen-C NR (codeine and guaifenesin)?

This medicine may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.

Do not drink alcohol. Dangerous side effects or death could occur.

Ask a doctor or pharmacist before using any other cough or cold medicine. Many combination medicines contain guaifensin. Taking certain products together can cause you to get too much of this medicine.

What are some other side effects of this drug?

All drugs may cause side effects. However, many people have no side effects or only have minor side effects. Call your doctor or get medical help if any of these side effects or any other side effects bother you or do not go away:
