Mepergan containing Meperidine Hydrochloride and Promethazine Hydrochloride

Your doctor has ordered meperidine, a strong analgesic (painkiller), to relieve your pain. The drug will be either injected into a large muscle (such as your buttock or hip) or added to an intravenous fluid that will drip through a needle or catheter placed in your vein or under your skin. You may receive meperidine continuously for around-the-clock pain relief. Your doctor also may order other pain medications to make you more comfortable. Mepergan containing Meperidine Hydrochloride and Promethazine Hydrochloride is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. Your health care provider (doctor, nurse, or pharmacist) may measure the effectiveness and side effects of your treatment using laboratory tests and physical examinations. It is important to keep all appointments with your doctor and the laboratory. The length of treatment depends on how you respond to the medication.
