HOW TO USE: This medication is given by injection into a vein or muscle by a health care professional, as directed by your doctor.

If you wait until the pain has worsened, the medication may not work as well. Suddenly stopping this medication may cause withdrawal, especially if you have used it for a long time or in high doses. To prevent withdrawal, your doctor may lower your dose slowly. Tell your doctor or pharmacist right away if you have any withdrawal symptoms such as restlessness, mental/mood changes (including anxiety, trouble sleeping, thoughts of suicide), watering eyes, runny nose, nausea, diarrhea, sweating, muscle aches, or sudden changes in behavior. When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.
