NSO and the Institute for Safe Medication Practices (ISMP) have teamed up to help you practice safe medication use and keep patients safe. The following is an ISMP Medication Safety Alert from the August 2017 NSO Risk Advisor.
rectal gel) has been available for a number of years, the DIASTAT ACUDIAL
delivery system was approved in 2005. The Diastat AcuDial delivery system is used for the acute treatment of patients two years and older on stable anti-epileptic medications who experience bouts of increased seizure activity (both prolonged and cluster seizures). Since the product’s introduction, the Institute for Safe Medications Practices has received a number of reports of errors using the device because it was not properly dialed and locked by the pharmacist prior to dispensing. Some of these errors have led to respiratory depression and required emergent intervention.
In one case, a 4-year-old girl with complex seizure disorder was prescribed Diastat AcuDial 5 mg. The pharmacy, however, dispensed an unlocked 10 mg Diastat AcuDial rectal syringe. Luckily, her parents had been educated to check that the dose was locked in at 5 mg and reported this dispensing mishap to the pediatric neurologist and pharmacy before administering it to their daughter.
A second case involved a young boy weighing 8 kg also with complex partial seizure disorder. Unfortunately, unlike the case above, the parents of this patient were not provided education on what to check for when using Diastat AcuDial. The pharmacy dispensed an unlocked 10 mg Diastat AcuDial rectal syringe and the parents administered the entire contents to their son. The child developed respiratory depression, was transported to the emergency room, and thankfully recovered.
More recently, the parent of a disabled adult with a seizure disorder reported that her daughter received a Diastat AcuDial rectal syringe that had been locked at an incorrect dose. The patient’s prescribed dose was 15 mg, but the pharmacist mistakenly locked the dose at 20 mg. The patient’s parent did not discover the error until after she had administered the dose. The patient was lethargic and slept for over 15 hours following administration.
The Diastat AcuDial delivery system is available as a 10 mg and a 20 mg rectal syringe designed to deliver minimum dosages of 5 mg or 12.5 mg respectively with dosage increments of 2.5 mg. Each package comes with two unlocked rectal syringes per package. Before the product is dispensed, both syringes must be dialed, set, and locked to the prescribed dose by the pharmacist, even when the maximum dose is prescribed. Once set and locked, the prescribed dose will appear in the dose display window and the locking ring, designated with a green ready band, will be engaged. To aid the pharmacist in locking the prescribed dose, the Diastat AcuDial package insert includes pharmacist instructions for the steps that need to be taken before dispensing the product to the patient (Figure 1

Ensure nurses know to confirm the prescribed dose has been dialed, set, and locked by the pharmacist. If the dose has not been locked or the green ready band is not visible, contact the pharmacy prior to administering the medication. Educate patients and caregivers how to use the device, including confirming that: the prescribed dose is visible in the display window; the green ready band is visible; and the smaller rectal tip size is used if the patient is a child.
