Benefits and Risks – Programmable Drug Pumps
Studies show that programmable drug pumps (intrathecal drug delivery systems) may increase pain relief and comfort for people with severe chronic pain.1-5 Talk with your doctor about the benefits, risks, and responsibilities involved with using a drug pump for painful neuropathy.
Typically, people who have success with pumps:
- Experience significant pain relief1-5
- Use significantly smaller doses than oral medication1-5
- Have fewer side effects than those using oral medications1-5
- Are able to improve their activities of daily living1-5
In addition, with this treatment:
- Dosage may be adjusted for your comfort
- It is reversible – your doctor can completely remove the system
- Therapy can be tried for a short period of time before you receive a permanent implant
As with any pain treatment, side effects can occur.
Risks may include:
- Surgical complications, such as infection
- Drug side effects (symptoms of overdose or underdose)
- Blood (hematoma) or fluid (seroma) in the area where the pump is implanted
- Spinal fluid leaks resulting in headaches or other problems, and injury to the spinal cord
- A dislodged or blocked catheter
- The pump could stop working
- Inflammatory mass at the tip of the catheter
These complications could cause a reduction in or loss of pain relief and may require surgery to correct.
