Step 4

Using your finger and thumb, gently pinch and
pull back the patient’s cheek. Place the tip of the
syringe into the back of the space between the
inside cheek and the lower gum (buccal cavity).


Epistatus 10 mg oromucosal solution contains the medicine midazolam, which belongs to a group of
medicines known as benzodiazepines.
Epistatus is used to stop a prolonged, convulsive seizure (‘fit’) in children and adolescents aged 10 to less
than 18 years.
This medicine must only be given by parents or caregivers where the patient has been diagnosed with

Do not give Epistatus if the patient has:
• An allergy (hypersensitivity) to midazolam, to any other benzodiazepine medicines (such as diazepam
or nitrazepam), or to any of the other ingredients of this medicine (listed in section 6).
• An illness called ‘myasthenia gravis’ (which causes muscle weakness).
• Severe breathing problems.
• Sleep apnoea syndrome (which causes breathing to be frequently interrupted during sleep).
• Severe liver problems.

Step 5

Slowly administer approximately half of the
solution to the buccal cavity on one side of the
mouth, and then administer the remainder
slowly to the other side, by pressing the syringe
plunger until it stops. If it is particularly difficult
to get the syringe into one buccal cavity, then
administer the whole dose over a duration of 4
– 5 seconds into the other buccal cavity.

Epistatus contains a small amount of alcohol; it should not be used if the patient is also taking disulfiram, a
medicine prescribed to deter alcohol use that causes headache, nausea, vomiting and other unpleasant

the face, lips, tongue or other parts of the body.

Other medicines and Epistatus
Tell the doctor or pharmacist if the patient is using, has recently used or might use any other medicines
including over-the-counter medicines or herbal medicines. This is extremely important, as using more than
one medicine at the same time can strengthen or weaken the effect of the medicines involved.

If the patient is going to have an inhaled anaesthetic (one that the patient breathes in) for an operation or for
dental treatment, it is important to tell the doctor or dentist that they have been given Epistatus.

The following side effects are common and may affect up to 1 in 10 people:
• sleepiness and losing consciousness
• reduced alertness
• feeling sick or being sick (vomiting)
The following side effects are uncommon and may affect up to 1 in 100 people:
• rash
• hives (lumpy rash)
• itchiness
The following side effects are very rare and may affect up to 1 in 10 000 - they have been reported when
midazolam (the active ingredient in Epistatus) is given as an injection, but may also be relevant to this

Epistatus with food and alcohol
The patient must not drink alcohol if they have been given Epistatus. Alcohol may increase the sedative
effects of Epistatus and make them very sleepy.

• agitation
• hostility, anger or aggression (including physical aggression)
• confusion
• euphoria (an excessive feeling of happiness or excitement)
• hallucinations (seeing and possibly hearing things that are not really there)

The patient must not take grapefruit juice if they have been given Epistatus. Grapefruit juice may increase
the sedative effect of Epistatus and make them more sleepy.
Pregnancy, breast-feeding and fertility
If the patient is pregnant, thinks she might be pregnant or is planning to have a baby, ask a doctor for advice
before giving this medicine.

Muscle problems:
• muscle spasms and muscle tremors (shaking of the patient’s muscles that they cannot control)

Frequent doses of this medicine during the last 3 months of pregnancy or during childbirth can cause
problems for the baby; these can include abnormal heart rhythms, hypothermia (low body temperature),
poor suckling, breathing difficulties and poor muscle tone at birth.

Mental and Nervous system problems:
• headache
• dizziness
• fits
• unusual talkativeness with loss of inhibition, possibly with excessive movement
• difficulty co-ordinating muscles
• temporary memory loss. How long this lasts depends on how much Epistatus the patient was given.
The patient may experience this after their treatment. In isolated cases this has lasted for a long time.

Tell a doctor if the patient is breast-feeding. Even though small amounts of this medicine may pass into
breast milk, it may not be necessary to stop breast-feeding. The doctor will advise if the patient should
temporarily stop breast-feeding after being given Epistatus.
Animal studies did not show an impairment of fertility.

Heart and circulation problems:
• low blood pressure
• slow heart rate
• redness of the face and neck (flushing), fainting or headache
