Meperidine is a narcotic pain reliever, similar to morphine. Meperidine is prescribed to treat moderate to severe pain. This medication is not intended for long-term use to treat chronic pain. Meperidine is Demerol without any Tylenol or aspirin in it. Meperidine is available only by prescription. Learn More About Meperidine Uses

Administration/Dosage

Physicians typically prescribe 25 to 150 mg of meperidine orally, intramuscular, subcutaneously or intravenously every three to four hours as needed. Meperidine syrup is also available. Oral meperidine is only half as effective as intravenous solution, so oral therapy is discouraged. Since meperidine is prescribed to be taken on an as-needed basis, people who have used meperidine for a very short amount of time should be able to miss a dose without any problems. However, meperidine can be habit-forming; people who have used this opiate for a long period of time or for recreational purposes may suffer unpleasant withdrawal symptoms soon after missing a dose.

Meperidine safety has not been established in children. Newborns and young children may be more prone to respiratory depression when taking meperidine. Elderly patients may be more prone to liver and kidney problems, exacerbated by meperidine use.

Action

Meperidine works by binding with opiate receptors in your brain and central nervous system. This changes the way your brain perceives pain. You may also feel a euphoric, relaxed sensation when taking meperidine. More About How Meperidine Works

Meperidine can make you dizzy or drowsy. Be careful when rising to a standing position. Do not operate heavy machinery until you know how meperidine makes you feel.

Meperidine may cause constipation. Drink six to eight glasses of water daily to reduce constipation. Discuss increasing your dietary fiber with your physician or nutritionist.

This drug can be habit-forming, especially if you take it for long periods of time. Tell your doctor if meperidine stops controlling your pain effectively – this may be a sign of increased tolerance. Do not increase your dose without discussing it with your physician.

Abuse

Meperidine carries a significant risk for abuse and physical as well as psychological dependence. Pharmaceutical companies legally manufacture meperidine for licit use as a pain reliever but abusers obtain meperidine through forged prescriptions, bogus prescription call-ins to pharmacies, "doctor shopping" as well as theft from pharmacies and friends.

Withdrawal

People who use meperidine by prescription to treat pain are not likely to develop mental dependence but may develop physical dependence. You may experience unpleasant withdrawal symptoms when you stop taking meperidine, especially if you have been using high doses or taking the opioid for a long period of time. Symptoms vary in intensity. Withdrawal is a normal, predictable, physical sign of dependency, not necessarily a sign of willful abuse. Withdrawal symptoms may prevent you from quitting meperidine without medical assistance.

Detox

Dependency and addiction to Meperidine is often difficult to overcome on your own, especially if you have been taking large doses or using these opioids for a long time. Fortunately, there are in-patient and out-patient treatment facilities where trained professionals can minimize withdrawal symptoms, detoxify your body and give you the tools you need to live drug-free. Detoxification, rehabilitation and counseling are effective therapies to treat addiction to Meperidine and other opiates.
