What is Meperidine?

Meperidine is an opioid medication used to treat moderate-to-severe pain.

Meperidine may also be used for purposes not listed in this medication guide.

Warnings

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

Using 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.

How should I take Meperidine

Meperidine comes as a tablet and a syrup (liquid) to take by mouth. It is usually taken with or without food every 3 to 4 hours as needed for pain. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.

If you are taking the meperidine tablets, swallow them whole; do not chew, break, or crush them. Swallow each tablet right after you put it in your mouth.

If you are taking meperidine syrup, use a dose-measuring spoon or cup to measure the correct amount of liquid for each dose, not a regular household spoon. Mix your dose with half a glass of water and swallow the mixture. Swallowing undiluted meperidine syrup may numb the mouth.

Your doctor will probably adjust your dose of meperidine during your treatment. Be sure to tell your doctor about any pain and side effects you experience while taking this medication. This will help your doctor find the dose that is best for you.

If you have taken meperidine for longer than a few weeks, do not stop taking the medication without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking meperidine, you may experience withdrawal symptoms. Withdrawal symptoms may include restlessness, watery eyes, stuffy nose, yawning, sweating, chills, muscle pain, irritability, nervousness, stomach pain, upset stomach, vomiting, loss of appetite, diarrhea, fast breathing, fast heartbeat, and back pain.

Dosing information

Follow the directions on your prescription label and read all medication guides. Never use meperidine in larger amounts, or for longer than prescribed. Tell your doctor if you feel an increased urge to take more of this medicine.

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

Meperidine oral is taken by mouth.

Meperidine injection is given as an infusion into a vein, or injected into a muscle or under the skin. A healthcare provider will give you this injection.

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

Do not stop using this medicine suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using meperidine.

Never crush or break a meperidine pill to inhale the powder or mix it into a liquid to inject the drug into your vein. This practice has resulted in death with the misuse of prescription drugs.

Store at room temperature away from moisture and heat. Keep track of your medicine. You should be aware if anyone is using it improperly or without a prescription.

Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.

Detailed Meperidine dosage information
Meperidine Dosage information (more detail)

Before Taking

You should not use meperidine if you are allergic to it, or if you have:

  • severe asthma or breathing problems; or

  • a blockage in your stomach or intestines.

Do not use meperidine if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.

Tell your doctor if you have ever had:

  • a head injury, brain tumor, or seizures;

  • breathing problems, sleep apnea;

  • drug or alcohol addiction, or mental illness;

  • a blockage in your stomach or intestines;

  • urination problems;

  • liver or kidney disease;

  • problems with your gallbladder, adrenal gland, or thyroid;

  • sickle cell anemia; or

  • abnormal curvature of the spine that affects breathing.

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.

Do not breastfeed while using meperidine. meperidine can pass into breast milk and cause drowsiness, breathing problems, or death in a nursing baby.

What happens if I miss a dose?

Since meperidine 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. A meperidine overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include slow breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, blue-colored skin or lips, fainting, or coma.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). You must immediately dispose of any medication that is outdated or no longer needed through a medicine take-back program. If you do not have a take-back program nearby or one that you can access promptly, flush any meperidine tablets or solution that are outdated or no longer needed down the toilet. Talk to your pharmacist about the proper disposal of your medication.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

What special dietary instructions should I follow?

Unless your doctor tells you otherwise, continue your normal diet.

What should I avoid while using Meperidine?

Do not drink alcohol. Dangerous side effects or death can occur when alcohol is combined with meperidine.

Avoid driving or hazardous activity until you know how meperidine will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries.

Meperidine side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

Meperidine may cause serious side effects. Stop using meperidine and call your doctor at once if you have:

  • slow heartbeats, weak or shallow breathing, breathing that stops during sleep;

  • severe drowsiness, feeling like you might pass out;

  • confusion, mood changes;

  • severe constipation;

  • tremors, muscle movements you cannot control, or a seizure (convulsions); or

  • low cortisol levels--nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

Serious side effects may be more likely in older adults and those who are malnourished or debilitated.

Long-term use of opioid medication may affect fertility (ability to have children) in men or women. It is not known whether opioid effects on fertility are permanent.

Common side effects of meperidine may include:

  • dizziness, drowsiness;

  • headache;

  • nausea, vomiting; or

  • sweating.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect Meperidine?

You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.

Opioid medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:

  • other narcotic medications--opioid pain medicine or prescription cough medicine;

  • a sedative like Valium--diazepam, alprazolam, lorazepam, Xanax, Klonopin, Versed, and others;

  • drugs that make you sleepy or slow your breathing--a sleeping pill, muscle relaxer, medicine to treat mood disorders or mental illness; or

  • drugs that affect serotonin levels in your body--a stimulant, or medicine for depression, Parkinson's disease, migraine headaches, serious infections, or nausea and vomiting.

This list is not complete. Other drugs may affect meperidine, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here.

What other information should I know?

Keep all appointments with your doctor.

Before having any laboratory test (especially those that involve methylene blue), tell your doctor and the laboratory personnel that you are taking meperidine.

Do not let anyone else take your medication. It is against the law to give this medication to anyone else. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
