## What is acetaminophen and hydrocodone?

Acetaminophen and hydrocodone is a combination medicine used to relieve moderate to moderately severe pain.

Hydrocodone is in a group of drugs called narcotic pain relievers.

Acetaminophen is a less potent pain reliever that increases the effects of hydrocodone.

Acetaminophen and hydrocodone may also be used for purposes other than those listed in this medication guide.

## Warnings

MISUSE OF ACETAMINOPHEN AND HYDROCODONE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.

Hydrocodone may be habit-forming and should be used only by the person it was prescribed for. Keep the medication in a secure place where others cannot get to it. Acetaminophen and hydrocodone can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Taking opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.

Fatal side effects can occur if you use opioid medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.

Tell your doctor if you drink more than three alcoholic beverages per day or if you have ever had alcoholic liver disease (cirrhosis). You may not be able to take medication that contains acetaminophen.

Stop taking acetaminophen and hydrocodone and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.

## Before taking this medicine

You should not use this medicine if you are allergic to acetaminophen or hydrocodone, or if you have:

- severe asthma or breathing problems; or

- a blockage in your stomach or intestines.

To make sure acetaminophen or hydrocodone is safe for you, tell your doctor if you have ever had:

- breathing problems, sleep apnea;

- liver disease;

- a drug or alcohol addiction;

- kidney disease;

- a head injury or seizures;

- urination problems; or

- problems with your thyroid, pancreas, or gallbladder.

If you use opioid medicine 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 opioids may need medical treatment for several weeks.

Tell your doctor if you feel an increased urge to use more of this medicine.

Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medicine in a place where others cannot get to it. Selling or giving away acetaminophen and hydrocodone is against the law.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

If you need surgery or medical tests, tell the doctor ahead of time that you are using this medicine.

Detailed Acetaminophen / hydrocodone dosage information

## What happens if I miss a dose?

Since this medicine is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next dose. Do not use two doses at one time.

## What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of acetaminophen and hydrocodone can be fatal.

The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.

Overdose can also cause severe muscle weakness, pinpoint pupils, very slow breathing, extreme drowsiness, or coma.

## What to avoid

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

Ask a doctor or pharmacist before using any other medicine that may contain acetaminophen (sometimes abbreviated as APAP). Taking certain medications together can lead to a fatal overdose.

In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. This could occur even if you have taken acetaminophen in the past and had no reaction.
