Diazepam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen).

Diazepam can slow or stop your breathing, especially if you have recently used an opioid medication, alcohol, or other drugs that can slow your breathing.

MISUSE OF Diastat AcuDial CAN CAUSE ADDICTION, OVERDOSE, OR DEATH. Keep the medication in a place where others cannot get to it.

This medicine is not for all types of seizures. If you are a caregiver, do not give this medicine unless you know how to recognize a seizure that should be treated with Diastat AcuDial.

Diastat AcuDial is usually given by a caregiver to the person having a seizure. If you are the caregiver, make sure you know and understand all instructions for giving the medicine.

Diastat AcuDial is not for all types of seizures. If you are the caregiver, do not give this medicine unless you know how to recognize the symptoms of a seizure episode that should be treated with this medicine.

Get emergency medical help if:

  • the seizure has not stopped within 15 minutes;
  • the seizure is different from the person's usual seizures;
  • the seizures are closer together or more severe than the person's usual seizures; or
  • the person has breathing problems, pale or blue-colored skin, or any other serious problems.

What other drugs will affect Diastat AcuDial?

Using diazepam with other drugs that make you sleepy or slow your breathing can cause dangerous side effects or death. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, prescription cough medicine, or medicine for depression or seizures.

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
