Acetaminophen and Codeine: MedlinePlus Drug Information

T IMPORTANT WARNING:
P The combination of acetaminophen and codeine may cause serious or life-threatening breathing problems, especially during the first 24 to 72 hours of your treatment and any time your dose is increased. Your doctor will monitor you carefully during your treatment. Tell your doctor if you have or have ever had slowed breathing or asthma. Your doctor will probably tell you not to take acetaminophen and codeine. Also tell your doctor if you have or have ever had lung disease such as chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways), a head injury or any condition that increases the amount of pressure in your brain. The risk that you will develop breathing problems may be higher if you are an older adult or are weak or malnourished due to disease. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: slowed breathing, long pauses between breaths, or shortness of breath.
P When codeine-containing medication was used in children, serious and life-threatening breathing problems such as slow or difficulty breathing and deaths were reported. Acetaminophen and codeine should never be used to treat pain or cough in children younger than 12 years of age or to relieve pain after surgery to remove the tonsils and/or adenoids in children younger than 18 years of age. Acetaminophen and codeine should not be used in children 12 to 18 years of age who are obese or who have a neuromuscular disease (disease that affects the nerves that control voluntary muscles), a lung disease, or obstructive sleep apnea (condition in which the airway becomes blocked or narrow and breathing stops for short periods during sleep) as these conditions may increase their risk of breathing problems.
P Taking too much acetaminophen (found in this combination preparation) can cause liver damage, sometimes serious enough to require liver transplantation or cause death. You might accidentally take too much acetaminophen if you do not follow the directions on the prescription or package label carefully, or if you take more than one product that contains acetaminophen. Be aware that you should not take more than 4,000 mg of acetaminophen per day. Tell your doctor if you have or have ever had liver disease. If you need to take more than one product that contains acetaminophen, it may be difficult for you to calculate the total amount of acetaminophen you are taking. Ask your doctor or pharmacist to help you.
P Taking certain medications during your treatment with acetaminophen and codeine may increase the risk that you will experience breathing problems or other serious, life threatening breathing problems, sedation, or coma. Tell your doctor if you are taking or plan to take any of the following medications: certain antifungal medications including itraconazole (Onmel, Sporanox), ketoconazole (Nizoral), and voriconazole (Vfend); benzodiazepines such as alprazolam (Xanax), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), and triazolam (Halcion); carbamazepine (Carbatrol, Epitol, Equetro, Tegretol, Teril); erythromycin (Erytab, Erythrocin); certain medications for human immunodeficiency virus (HIV) including indinavir (Crixivan), nelfinavir (Viracept), and ritonavir (Norvir, in Kaletra); muscle relaxants; other pain medications; phenytoin (Dilantin, Phenytek); rifampin (Rifadin, Rimactane, in Rifamate); sedatives; sleeping pills; or tranquilizers. Your doctor may need to change the dosages of your medications and will monitor you carefully. If you take acetaminophen and codeine with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.
P Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with acetaminophen and codeine increases the risk that you will experience serious, life-threatening side effects. Do not drink alcohol, take prescription or nonprescription medications that contain alcohol, or use street drugs during your treatment.
P The combination of acetaminophen and codeine may be habit-forming. Do not take more of it, take it more often, or take it in a different way than directed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse acetaminophen and codeine if you have or have ever had any of these conditions.
P Tell your doctor if you are pregnant or plan to become pregnant. If you take acetaminophen and codeine regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth. Tell your baby's doctor right away if your baby experiences any of the following symptoms: irritability, hyperactivity, abnormal sleep, high-pitched cry, uncontrollable shaking of a part of the body, vomiting, diarrhea, or failure to gain weight.
P Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with acetaminophen and codeine and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

T Why is this medication prescribed?
P The combination of acetaminophen and codeine is used to relieve mild to moderate pain. Acetaminophen is in a class of medications called analgesics (pain relievers) and antipyretics (fever reducers). It works by changing the way the body senses pain and by cooling the body. Codeine belongs to a class of medications called opiate (narcotic) analgesics and to a class of medications called antitussives. When codeine is used to treat pain, it works by changing the way the brain and nervous system respond to pain. When codeine is used to reduce coughing, it works by decreasing the activity in the part of the brain that causes coughing.

T How should this medicine be used?
P The combination of acetaminophen and codeine comes as a tablet, capsule, and liquid to take by mouth. It usually is taken every 4 hours as needed. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take acetaminophen and codeine exactly as directed.
P If you have taken acetaminophen and codeine for several weeks or longer, do not stop taking the medication without talking to your doctor. Your doctor may decrease your dose gradually. If you suddenly stop taking acetaminophen and codeine, you may experience withdrawal symptoms such as restlessness, widened pupils (black circles in the center of the eyes), teary eyes, irritability, anxiety, runny nose, difficulty falling asleep or staying asleep, yawning, sweating, fast breathing, fast heartbeat, chills, nausea, loss of appetite, vomiting, diarrhea, stomach cramps, or muscle aches.

T Other uses for this medicine
P This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
