Read the instruction manual and directions that come with your infusion pump. If you have any questions, ask your doctor or pharmacist.

This medication is given by injection as directed by your doctor, usually continuously into the spinal fluid (intrathecal) using a small pump. To decrease the risk of side effects, treatment is usually started slowly and then gradually increased to the best dose for you. The dosage is based on your medical condition and response to treatment.

This medication should not be given into a vein (IV) or under the skin. It can cause fainting due to a dangerous drop in blood pressure if it is accidentally given into a vein.

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.

To prevent infection, learn how to handle the infusion pump, and learn proper care of the injection site. Call your doctor right away if there is any sign of infection around the injection site (such as swelling, redness, tenderness).

Contact your doctor or pharmacist to set up a schedule for refilling your pump.

Inform your doctor if your pain lasts or gets worse.
