Overview

 It works on the brain to treat pain signals to adjust the way the body reacts and responds to pain. Demerol may not be used to treat any ongoing or long-term preexisting pain. It must only be used to treat moderate to severe and sudden pain and heart attacks.

What is Demerol?

Demerol a.k.a. Meperidine is a kind of opioid pain medication or analgesic. It is also known as a narcotic.

Dosage and Administration

Here is the proper dosing for adult use of Demerol for pain and other related ailments:

Recommended adult dosage for pain

Oral use

Fifty milligrams to 150 milligrams every 3 to 4 hours or as needed. The maximum dosage per day is 600 milligrams. 

PCA or Patient Controlled Analgesia use

The first dose is 10 milligrams, with a range of 1 to 5 milligrams for every incremental dose. Do not use for 6 to 10 minutes, then adjust the dosage depending on the patient’s response to the drug. For intravenous infusion, the dosage for adult use is 15 milligrams to 35 milligrams per hour. 

Parenteral use

The dosage for parenteral use is 50 milligrams to 150 milligrams subcutaneously or IM for every 3 to 4 hours or as needed. The administration IM is best when Demerol repeated use is required. It may be administered intravenously, but when lower doses are needed, it must be in a diluted solution and administered slow.

For pain management of severe pain, it is sufficient to need an opioid analgesic only when alternative treatments are insufficient and unable to treat pain.

Using Demerol Vial

Demerol, in this case, is administered through an injection to the vein, to the muscle, or under the skin as directed by the physician.

When you are administering the medication at home, all by yourself, you have to learn first hand the correct usage and preparation from your physician. Before you use it, check the product for any discoloration or diluted particles. If there are some present, refrain from using it. But, know how you can safely discard medical supplies properly.

Whenever Demerol is administered to the vein, it is given rather very slowly to avoid any serious side effects. When this medication is given under the skin or muscle, it is important that you change the injection site every time to prevent any injury or trauma to the skin. Do not lie down when the injection is administered as it can result in drowsiness

Dosage is always based on your medical condition and response to the Demerol treatment. Never attempt to increase your dose, use it more often, or for longer than the one prescribed by your doctor as your risk for serious side effects is very likely. Stop the medication altogether if you experience any severe side effects. 

Demerol and other pain medications function best if used when you experience first signs of pain. If you wait until such a time when the pain becomes hard to bear, the medication will not work as effectively as expected. 

Do not stop using Demerol abruptly. Doing so can lead to withdrawal, especially for those who have used it for an extended period and in very high doses. To avoid withdrawal, your physician will require to lower the dose very slowly. Inform the physician immediately if you experience any withdrawal symptoms like mood changes, problems sleeping, anxiety, restlessness, thought of suicide, nausea, runny nose, watering eyes, muscle aches, diarrhea, and any abrupt mood or behavior changes. 

Drug Interaction

The interaction of certain drugs can change how your medication works or increase your susceptibility to certain side effects. This does not contain an all-inclusive drug interactions list. It is vital to have a list of all the products you use – prescription or non-prescription, including herbal products. That way, your doctor will know when to reduce, stop, or modify the dosage of your medication. 

Some medicines can interact with Demerol like pain medications that have opioid agonist-antagonists like butorphanol, naltrexone, nalbuphine, and pentazocine. 

Do not take Demerol with any MAO inhibitors as it can lead to dangerous drug interaction. Stay away from MAO inhibitors like methylene blue, isocarboxazid, phenelzine, rasagiline, procarbazine, safinamide, selegiline, tranylcypromine, and moclobemide. MAO inhibitors must not be taken for two weeks before treatment with Demerol. Inquire with your physician if you should start or stop taking certain medications with Demerol. 

Warnings and Precautions

The severe side effects can be heightened like slow breathing, feel dizziness, severe drowsiness, or more if Demerol is used with other products or drugs that can also lead to breathing problems or drowsiness. Ask your doctor or nurse if you are taking other opioid pain reliever or cough medicines like hydrocodone, alcohol, codeine, marijuana, or medication for anxiety or sleeping problems like lorazepam, zolpidem, or alprazolam. Also, do not take Demerol with antihistamines like cetirizine, diphenhydramine, or muscle relaxants like cyclobenzaprine, or carisoprodol.
