meperidine - injection, Demerol (cont.)
HOW TO USE: This medication is given by injection into a vein, into a muscle, or under the skin as directed by your doctor. When meperidine is injected into a vein, it is given very slowly to prevent serious side effects. If this medication is given into a muscle or under the skin, it is important to change the location of the injection site to avoid developing problem areas under the skin.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 should be lying down when the injection is given to prevent side effects such as dizziness.If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.If nausea occurs, consult your doctor or pharmacist for ways to decrease it (e.g., antihistamines, lying down with as little head movement as possible).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.
