NARCOTIC ANALGESICS AND ACETAMINOPHEN (Systemic)
Some commonly used brand names are:
In the U.S.—
Other commonly used names are:
Combination medicines containing narcotic analgesics (nar-KOT-ik an-al-JEE-zicks) and acetaminophen (a-seat-a-MIN-oh-fen) are used to relieve pain. A narcotic analgesic and acetaminophen used together may provide better pain relief than either medicine used alone. In some cases, relief of pain may come at lower doses of each medicine.
Narcotic analgesics act in the central nervous system (CNS) to relieve pain. Many of their side effects are also caused by actions in the CNS. When narcotics are used for a long time, your body may get used to them so that larger amounts are needed to relieve pain. This is called tolerance to the medicine. Also, when narcotics are used for a long time or in large doses, they may become habit-forming (causing mental or physical dependence). Physical dependence may lead to withdrawal symptoms when you stop taking the medicine.
Acetaminophen does not become habit-forming when taken for a long time or in large doses, but it may cause other unwanted effects, including liver damage, if too much is taken.
In the U.S., these medicines are available only with your medical doctor"s or dentist"s prescription. In Canada, some acetaminophen, codeine, and caffeine combinations are available without a prescription.
These medicines are available in the following dosage forms:
Before Using This Medicine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For narcotic analgesic and acetaminophen combinations, the following should be considered:
Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to acetaminophen or to a narcotic analgesic. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Breast-feeding—Acetaminophen, codeine, and propoxyphene pass into the breast milk. It is not known whether other narcotic analgesics pass into the breast milk. However, these medicines have not been reported to cause problems in nursing babies.
Children—Breathing problems may be especially likely to occur when narcotic analgesics are given to children younger than 2 years of age. These children are usually more sensitive than adults to the effects of narcotic analgesics. Also, unusual excitement or restlessness may be more likely to occur in children receiving these medicines.
Acetaminophen has been tested in children and has not been shown to cause different side effects or problems in children than it does in adults.
Older adults—Elderly people are especially sensitive to the effects of narcotic analgesics. This may increase the chance of side effects, especially breathing problems, during treatment.
Acetaminophen has been tested and has not been shown to cause different side effects or problems in older people than it does in younger adults.
Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking a narcotic analgesic and acetaminophen combination, it is especially important that your health care professional know if you are taking any of the following:
Other medical problems—The presence of other medical problems may affect the use of narcotic analgesic and acetaminophen combinations. Make sure you tell your doctor if you have any other medical problems, especially:
Proper Use of This Medicine
Take this medicine only as directed by your medical doctor or dentist . Do not take more of it, do not take it more often, and do not take it for a longer time than your medical doctor or dentist ordered. This is especially important for young children and elderly patients, who may be more sensitive than other people to the effects of narcotic analgesics. If too much of a narcotic analgesic is taken, it may become habit-forming (causing mental or physical dependence) or lead to medical problems because of an overdose. Taking too much acetaminophen may cause liver damage.
If you think that this medicine is not working properly after you have been taking it for a few weeks, do not increase the dose . Instead, check with your medical doctor or dentist.
Dosing—The dose of these medicines will be different for different patients. Follow your doctor"s orders or the directions on the label . The following information includes only the average doses of these medicines. If your dose is different, do not change it unless your doctor tells you to do so.
The number of capsules or tablets or teaspoonfuls of solution or suspension that you take depends on the strength of the medicine.
Missed dose—If your medical doctor or dentist has ordered you to take this medicine according to a regular schedule and you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses .

Precautions While Using This Medicine
If you will be taking this medicine for a long time (for example, for several months at a time), or in high doses, your doctor should check your progress at regular visits.
Check the labels of all nonprescription (over-the-counter [OTC]) and prescription medicines you now take . If any contain acetaminophen or a narcotic be especially careful, since taking them while taking this medicine may lead to overdose. If you have any questions about this, check with your medical doctor, dentist, or pharmacist.
The narcotic analgesic in this medicine will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; other prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Also, there may be a greater risk of liver damage if you drink three or more alcoholic beverages while you are taking acetaminophen. Do not drink alcoholic beverages, and check with your medical doctor or dentist before taking any of the medicines listed above, while you are using this medicine .
Too much use of the acetaminophen in this combination medicine together with certain other medicines may increase the chance of unwanted effects. The risk will depend on how much of each medicine you take every day, and on how long you take the medicines together. If your doctor directs you to take these medicines together on a regular basis, follow his or her directions carefully. However, do not take this medicine together with any of the following medicines for more than a few days, unless your doctor has directed you to do so and is following your progress:
This medicine may cause some people to become drowsy, dizzy, or lightheaded, or to feel a false sense of well-being. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert and clearheaded .
Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem.
Nausea or vomiting may occur, especially after the first couple of doses. This effect may go away if you lie down for a while. However, if nausea or vomiting continues, check with your medical doctor or dentist. Lying down for a while may also help relieve some other side effects, such as dizziness or lightheadedness, that may occur.
Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are taking this medicine.
Narcotic analgesics may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
If you have been taking this medicine regularly for several weeks or more, do not suddenly stop taking it without first checking with your doctor . Your doctor may want you to reduce gradually the amount you are taking before stopping completely, to lessen the chance of withdrawal side effects. This will depend on which of these medicines you have been taking, and the amount you have been taking every day.
If you think you or someone else may have taken an overdose of this medicine, get emergency help at once . Taking an overdose of this medicine or taking alcohol or CNS depressants with this medicine may lead to unconsciousness or death. Signs of overdose of narcotics include convulsions (seizures), confusion, severe nervousness or restlessness, severe dizziness, severe drowsiness, shortness of breath or troubled breathing, and severe weakness. Signs of severe acetaminophen overdose may not occur until several days after the overdose is taken.
