GENERIC NAME: MEPERIDINE LIQUID - ORAL (meh-PAIR-id-een)
BRAND NAME(S): Demerol
USES: This medication is used to treat moderate to severe pain. Meperidine acts on certain centers in the brain to give you pain relief. This medication is a narcotic pain reliever similar to morphine.
HOW TO USE: Take this medication by mouth, usually every 3 to 4 hours as needed or as directed by your doctor. Use a special measuring spoon or device to measure out your dose. Do not use a household spoon, or you may not get the correct dose. Mix your dose with one-half glass of water (4 ounces or 120 milliliters) and drink immediately. If this medication is not mixed in water before being taken, the mouth may become numb for a short time.You may take this drug with or without food. If you have nausea, you may take this drug with food, although this may cause your body to absorb less of the drug and get less benefit from it. Consult your doctor or pharmacist about other ways to decrease nausea (e.g., antihistamines, lying down for 1-2 hours with as little head movement as possible).The dosage is based on your medical condition and response to therapy. Pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medication may not work as well.You may also take long-acting narcotic medications or use narcotic patches for ongoing pain if so directed by your doctor. In that case, this medication might be used for sudden (breakthrough) pain only as needed. Also follow your doctor's or pharmacist's instructions for safely using non-narcotic pain relievers (e.g., naproxen, ibuprofen). Ask your doctor if you have any questions.This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as restlessness, runny nose, watering eyes, trouble sleeping, severe abdominal/muscle pain, nausea, vomiting, rapid breathing, and fast heartbeat) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately.Though very unlikely, this medication can also be habit-forming and may result in abnormal drug-seeking behavior (addiction). To lessen the risk of becoming addicted, do not increase your dose, take it more frequently, or use it for a longer time than prescribed. Properly stop the medication when so directed.When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well.Inform your doctor if your pain persists or worsens.
