Opioid

Uses of This Medicine:

Meperidine injection is used to relieve moderate to severe pain. It belongs to the group of medicines called narcotic analgesics (pain medicines). Meperidine acts on the central nervous system (CNS) to relieve pain.

When a narcotic medicine is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.

This medicine is available only with your doctor's prescription.

Proper Use of This Medicine:

A nurse or other trained health professional will give you this medicine in a hospital. This medicine is given through a needle placed in one of your veins, or as a shot under your skin or in a muscle. When the medicine is given in your vein it must be injected slowly, so your IV will need to stay in place for awhile.

Precautions While Using This Medicine:

It is very important that your doctor check your progress while you are receiving this medicine. This is to make sure that the medicine is working properly, and to allow your doctor to check for any unwanted effects.

Do not use this medicine if you have taken a monoamine oxidase (MAO) inhibitor in the past 2 weeks. MAO inhibitors are used for depression, and some examples are isocarboxazid (Marplan®), phenelzine (Nardil®), selegiline (Eldepryl®), and tranylcypromine (Parnate®). If meperidine injection is used with MAO inhibitors, you may have unwanted effects like confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high temperature, an extremely high blood pressure, or convulsions.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds; sedatives, tranquilizers, or sleeping medicine; other prescription pain medicine or narcotics; medicine for seizures or barbiturates; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the medicines listed above while you are using this medicine.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in the diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.

This medicine may make you dizzy, drowsy, confused, or disoriented. 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 not alert.

Before having any kind of surgery (including dental surgery) or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine. Serious unwanted effects can occur if certain medicines are given together with meperidine injection.

If you have been using this medicine regularly for several weeks or longer, do not suddenly stop using it without checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent worsening of your condition and reduce the possibility of withdrawal symptoms, such as abdominal or stomach cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble with sleeping.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
