Update: 20 mg syringe has changed

The 20mg DIASTAT AcuDial syringe has been modified for the sake of simplification and to minimize potential dosing errors:
  • The 20 mg syringe cannot be used for 10 mg doses
  • The minimum dose in the 20 mg syringe is 12.5 mg
  • Use the maximum dose (10 mg) on the 10 mg syringe to deliver a 10 mg dose to patients.

Important note: Even when the maximum dose is prescribed, both syringes must be dialed and locked before dispensing.

Important change: The available doses from the 10 mg syringe are 5, 7.5, and 10 mg. The available doses from the 20 mg syringe are 12.5, 15, 17.5, and 20 mg.

Selecting the appropriate dose

In order to accurately prescribe DIASTAT AcuDial, the dose should be individualized for the maximum beneficial effect. The recommended dose has not changed and is still 0.2 — 0.5 mg/kg.

The following tables provide acceptable weight ranges for each dose and age category, such that patients will receive between 90% and 180% of the calculated recommended dose.

The safety of this strategy has been established in clinical trials.1

Print Dosing Recommendations Chart 
  • It is recommended that diazepam rectal gel be used to treat no more than five episodes per month and no more than one episode every five days.
  • Diazepam rectal gel is not recommended for chronic, daily use as an anticonvulsant because of the potential development of tolerance to diazepam.
  • Chronic daily use of diazepam may increase the frequency and/or severity of tonic clonic seizures, requiring an increase in the dosage of standard anticonvulsant medication. In such cases, abrupt withdrawal of chronic diazepam may also be associated with a temporary increase in the frequency and/or severity of seizures.

Please review and discuss the proper administration and disposal of DIASTAT AcuDial with your patients as well as how to inspect syringes to ensure tip is not cracked and proper dose has been dialed and locked.
