Orphenadrine is used to treat muscle spasms/pain. It is usually used along with rest, physical therapy, and other treatment.

This medication is given by injection into a vein or muscle by a health care professional. It is given as directed by your doctor, usually twice a day (every 12 hours). If this medication is injected into a vein, it should be given over 5 minutes while you are lying down. Continue to lie down for 5 to 10 minutes after the injection to reduce dizziness and lightheadedness.

To continue to control your symptoms, your doctor may switch you to a form of orphenadrine that is taken by mouth.

Tell your doctor if your condition does not get better or if it gets worse.

Dry mouth, dizziness, drowsiness, lightheadedness, blurred vision, nausea, vomiting, and constipation may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

To relieve dry mouth, suck (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.
