Questions and Answers – Drug Pumps
What is a drug pump?
A drug pump (intrathecal drug delivery system) is designed to reduce chronic pain by delivering pain medication to the intrathecal space that surrounds the spinal cord. Because this treatment delivers pain medication directly to the pain receptors near the spinal cord, smaller doses of medication are required to gain relief from painful neuropathy.1-5
How does a drug pump work?
The spinal cord is like a highway for pain signals going to the brain. Because the pump sends medication directly to the area around the spinal cord, it interrupts pain signals before they reach the brain. Results may vary depending upon the individual.
Is a drug pump right for me?
Talk to your doctor to determine what kinds of pain treatments may work for you. The choice of treatment depends on the type of pain, how severe it is, and how you respond to your pain treatment. If your doctor thinks you are a good candidate for a drug pump, you can complete a screening test so that you can experience the therapy to see if you are a good candidate.
Is the pump new?
No. The pump has been approved by the FDA since 1991 and has helped thousands of people worldwide.
Will drug delivery treatment completely eliminate my pain?
Typically, people who do not get adequate pain relief from oral medications get significant relief from drug delivery treatment.1-5 Drug delivery treatment does not eliminate the source of the pain, so the amount of pain relief varies from person to person.
Will the drug pump eliminate other sources of pain?
Your pump will not provide relief from other types of pain such as headaches, stomachaches, or fractures.
What is the surgery like?
The surgery to implant the system takes approximately 1 to 3 hours and a brief hospital stay.
What do I need to know about opioids (pain medication) used in my pump?
Some doctors choose to use an opioid medication in the drug pump. There are risks associated with the use of any opioid pain medication. For more details, see opioid pain medication question and answers.
