Meperitab

Generic name: Meperidine
Drug class: Opioids (narcotic analgesics)

Usage of Meperitab

Meperidine is used to relieve pain severe enough to require opioid treatment and when other pain medicines did not work well enough or cannot be tolerated. It belongs to the group of medicines called narcotic analgesics (pain medicines). Meperidine acts on the central nervous system (CNS) to relieve pain. This medicine should not be used to relieve chronic (long-lasting or recurrent) pain.

When meperidine 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 under a restricted distribution program called the Opioid Analgesic REMS (Risk Evaluation and Mitigation Strategy) program.

    Before taking Meperitab

    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 this medicine, the following should be considered:

    Allergies

    Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

    Pediatric

    Appropriate studies have not been performed on the relationship of age to the effects of meperidine in the pediatric population. Safety and efficacy have not been established.

    Geriatric

    Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of meperidine in the elderly. However, elderly patients are more likely to have age-related kidney, liver, or lung problems, which may require caution and an adjustment in the dose for patients receiving meperidine.

    Breast Feeding

    There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

    How to use Meperitab

    Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of this medicine is taken for a long time, it may become habit-forming (causing mental or physical dependence).

    It is very important that you understand the rules of the Opioid Analgesic REMS program to prevent addiction, abuse, and misuse of meperidine. This medicine should come with a Medication Guide. Read and follow these instructions carefully. Read it again each time you refill your prescription in case there is new information. Ask your doctor if you have any questions.

    Measure the oral liquid with a marked measuring spoon, oral syringe, or medicine cup. Never use an average household teaspoon or tablespoon to measure the dose of this medicine.

    Mix each dose of the liquid into a one-half glass of water and drink all of the mixture in order to get the correct amount of medicine. This may help lessen the numbing effects of the oral liquid.

    Swallow the tablet whole. Do not crush, break, or chew it.

    Drink plenty of fluids to help avoid constipation during treatment with this medicine.

    Dosing

    The dose of this medicine 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 this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

    The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

  • For oral dosage forms (solution or tablets):
  • For moderate to severe pain:
  • Adults—50 to 150 milligrams (mg) every 3 or 4 hours as needed.
  • Children 1 year of age and older—Dose is based on body weight and must be determined by your doctor. The dose is usually 1.1 to 1.8 milligrams (mg) per kilogram (kg) of body weight per dose given every 3 or 4 hours as needed.
  • Children younger than 1 year of age—Use and dose must be determined by your doctor.
  • Missed Dose

    If you miss a dose of this medicine, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

    Storage

    Keep out of the reach of children.

    Do not keep outdated medicine or medicine no longer needed.

    Ask your healthcare professional how you should dispose of any medicine you do not use.

    Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

    Meperidine can cause serious unwanted effects if taken by adults who are not used to strong narcotic pain medicines. Make sure you store the medicine in a safe and secure place to prevent others from getting it.

    Drop off any unused narcotic medicine at a drug take-back location right away. If you do not have a drug take-back location near you, flush any unused narcotic medicine down the toilet. Check your local drug store and clinics for take-back locations. You can also check the DEA web site for locations.

    Warnings

    It is very important that your doctor check your progress while you are using this medicine, especially within the first 24 to 72 hours of treatment. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to use it. Blood and urine tests may be needed to check for unwanted effects.

    Do not use this medicine with a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking meperidine during the 2 weeks after you stop an MAO inhibitor. Wait for 2 weeks after stopping meperidine before you start taking an MAO inhibitor. If you take them together or do not wait 2 weeks, you may have confusion, agitation, restlessness, stomach or bowel symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.

    Using too much meperidine may cause an overdose. Symptoms of an overdose include: extreme dizziness or weakness, trouble breathing, slow heartbeat or breathing, seizures, or cold, clammy skin. In case of an overdose, call your doctor right away. Your doctor may also give naloxone to treat an overdose.

    Check with your doctor before using this medicine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with meperidine may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

    This medicine may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea (stop breathing for short periods during sleep) while 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 lots of fluids, or increase the amount of fiber in your diet. Be sure to follow these directions carefully, because continuing constipation can lead to more serious problems.

    This medicine may cause adrenal gland problems. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.

    Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help. Also, lying down for a while may relieve the dizziness or lightheadedness. If this problem continues or gets worse, check with your doctor.

    Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

    This medicine may make you dizzy, drowsy, confused, or disoriented. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

    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.

    Do not stop using this medicine without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This is to decrease the chance of having certain side effects when you stop the medicine, including agitation, anxiety, dizziness, a feeling of constant movement of self or surroundings, headaches, increased sweating, nausea, trembling or shaking, trouble sleeping or walking, or unusual tiredness.

    Using this medicine while you are pregnant may cause serious unwanted effects, including neonatal opioid withdrawal syndrome in your newborn baby. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using this medicine.

    For nursing mothers:

  • Talk to your doctor if you have any questions about taking meperidine or about how this medicine may affect your baby.
  • Call your doctor if you become extremely tired and have difficulty caring for your baby.
  • Your baby should generally nurse every 2 to 3 hours and should not sleep for more than 4 hours at a time.
  • Check with your doctor or hospital emergency room immediately if your baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, difficulty breathing, or limpness. These may be symptoms of an overdose and need immediate medical attention.
  • Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

    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 (eg, St. John's wort) or vitamin supplements.
