A call to the clinical call line from a health care provider was received on (b)(6) 2021 regarding a patient who was admitted to a hospital with suspected morphine withdrawal.The patient has a codman 3000 pump, low flow, which is being used to deliver morphine to treat chronic pain.Patient symptoms were reported to be convulsions, nausea and vomiting.The patient was treated with iv morphine to treat withdrawal symptoms.It was initially reported that the patient's prior refill was (b)(6) 2021 and the next refill was scheduled for (b)(6) 2021.The pump is a 30ml pump with a flow rate of 0.5ml/day.Intera clinical informed the health care provider that the pump is never to be allowed to go below 2 ml in the reservoir, so should be refilled no later than at 56-58 days from the last refill (per the codman 3000 ifu).The date of adverse event ((b)(6) 2021) was 63 days from the last refill, so the pump is most likely empty and the patient went into in morphine withdrawal.Further discussion with the health care provider's office on nov 9, 2021 later clarified that the patient was also scheduled for a pump refill on (b)(6) 2021, which would have been within the refill interval; however, patient was administered a sacroiliac injection instead of a pump refill.Health care provided stated this was a scheduling error by the healthcare provider's office.Patient had pump refilled in the hospital on (b)(6) 2021 and discharged at a later date.Exact date of discharge was not reported.The patient later called the healthcare provider's office on (b)(6) 2021 to report that she felt cold and clammy and could hear heartbeat.The healthcare provider instructed her to go to the hospital for a pneumonia diagnosis as he felt these symptoms were not symptoms of morphine withdrawal.It is unknown if the patient actually went to the hospital at this time.The patient returned to the healthcare provider on (b)(6) 2021 to report that she still had morphine withdrawal symptoms that would "come and go." the health care provider prescribed tramadol by mouth for symptoms, and the patient continues to take tizanidine for muscle contractions.No device malfunction was reported or alleged.Pump explant is not currently planned at the time of this report.
