Meperidine is used to relieve moderate to severe pain. Meperidine is in a class of medications called narcotic analgesics, a group of pain medications similar to morphine. It works by changing the way the body senses pain.
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.
Swallow the tablets whole: do not chew or crush them.
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.
Meperidine can be habit-forming. Take meperidine exactly as directed. Do not take a larger dose, or take it more often or for a longer period of time than you were told by your doctor. Do not snort or try to inject the tablets. Meperidine may cause serious side effects or death if it is taken or used in these ways.
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.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
talk to your doctor about the risks and benefits of taking meperidine if you are 65 years of age or older. Older adults should not usually take meperidine because it is not as safe or as effective as other medications that can be used to treat the same condition.
Unless your doctor tells you otherwise, continue your normal diet.
This medication is usually taken as needed. If your doctor has told you to take meperidine regularly, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
