When you first start using this medication, it must be given by a health care professional in a hospital or clinic. This medication is given as a continuous injection into the vein using an infusion pump as directed by your doctor.

Follow all instructions from your health care professional about how to properly use and prepare this medication and the infusion pump. Learn how to properly care for your injection site and how to avoid infection. Also learn how to store and discard needles and medical supplies safely. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid, and contact your health care professional right away. If you have any questions about the use of this medication or the infusion pump, consult your health care professional.

Do not suddenly decrease the dose or suddenly stop using this medication because doing either may lead to serious (rarely fatal) worsening of your condition. If you must stop this medication, gradually reduce the dose as directed by your doctor. Consult your doctor right away if your infusion is interrupted or if you develop worsening trouble breathing, dizziness, or weakness. To avoid interruptions in drug treatment, you should have a backup infusion pump and infusion sets available in case your equipment fails. Consult your health care professional for more information.

The dosage is based on your medical condition, weight, and response to treatment. Your doctor may also direct you to use additional medications to treat your condition and prevent problems. Use all prescribed medications exactly as directed.

Tell your doctor if your condition does not improve or if it worsens.
