The typical product life of your drug pump will range between 5 years and a maximum of 7 years, depending on how much medicine you’re programmed to receive each day. Your physician will closely monitor the performance of your programmable pump at each of your refill appointments.

When the time comes for a replacement, you will work with your physician to schedule surgery for a new pump implant.

elective replacement indicator

The drug pump has an elective replacement indicator (ERI) alarm that sounds approximately 90 days before the pump stops delivering therapy. A stopped pump results in a loss of therapy that can lead to an underdose or withdrawal symptoms. If you hear an ERI alarm, contact your doctor.

It is a good idea to schedule your replacement about 6 months prior to the automatic shut off so there is no interruption in your therapy.
