Factors Your Doctor May Consider – Intrathecal Baclofen Therapy

Your doctor will consider many important factors to decide if ITB therapy is right for you.

You may be a candidate for ITB therapy if you:

  • Have severe spasticity that interferes with your function, care and comfort, or activities of daily living
  • Show a positive response to a baclofen injection in a standard screening test
  • Have sufficient body size to support the pump, which must be implanted 2.5 centimetres (1 inch) or less from the surface of the skin
  • Do not have any infections
  • Are not allergic to baclofen

In addition, healthcare professionals may use the following criteria to determine if you are a candidate for a baclofen pump:

  • You experience severe spasticity or spasms that interfere with function or daily activities
  • Your severe spasticity or spasms interfere with care or positioning

About the Screening Test

A standard screening test determines if ITB therapy may work for you. During the test, you’ll be screened with a small dose of the drug baclofen injected into the intrathecal space (where fluid flows around the spinal cord).

In clinical studies during the screening test, baclofen reduced spasticity in 97% of people with severe spasticity due to multiple sclerosis or spinal cord injury .1

If You Are a Candidate

If your doctor determines you are a candidate for a baclofen pump, you will need to make the final decision about whether to pursue the therapy.

Here are some suggestions to help you decide if a baclofen pump is right for you:

  • Talk with people who have a baclofen pump.
  • Learn about our Ambassador Program.
  • Make sure you’re comfortable with your doctor. He or she should be helpful, supportive, and ready to answer any questions you may have.
  • Carefully weigh the benefits and risks of a baclofen pump.

Before you meet with your doctor, think about what you hope to learn. Prepare questions, and be ready to provide information about your medical history.
