What is Phenflu CD (acetaminophen, codeine, guaifenesin, and phenylephrine)?

Acetaminophen is a pain reliever and fever reducer.

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

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

Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

Acetaminophen, codeine, guaifenesin, and phenylephrine is a combination medicine used to treat headache, fever, body aches, cough, chest congestion, stuffy nose, and sinus 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.

Acetaminophen, codeine, guaifenesin, and phenylephrine may also be used for other purposes not listed in this medication guide.

How should I take this medicine?

Follow all directions on your prescription label. Never take this medicine in larger amounts, or for longer than prescribed. An overdose can damage your liver or cause death.

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 medication to a child younger than 6 years old. Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.

Do not take for longer than 7 days in a row. Stop taking the medicine and call your doctor if you still have a fever after 3 days of use, you still have pain after 7 days (or 5 days if treating a child), if your symptoms get worse, or if you have a skin rash, ongoing headache, or any redness or swelling.

If you need surgery or medical tests, tell the surgeon or doctor ahead of time if you have taken this medicine within the past few days.

Store at room temperature away from moisture and heat.

Keep track of the amount of medicine used from each new bottle. 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?

What should I avoid while taking this medicine?

Ask a doctor or pharmacist before using any other pain, cold, allergy, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines.

Alcohol may also increase your risk of liver damage while you are taking acetaminophen. Check your food and medicine labels to be sure these products do not contain alcohol.
