1. What Midazolam is and what it is used for

This medicine contains midazolam. Midazolam belongs to a group of medicines known as benzodiazepines. Midazolam is used to stop a sudden, prolonged, convulsive, seizure in infants, toddlers, children and adolescents (from 3 months to less than 18 years of age).

In infants from 3 months to less than 6 months it should only be used in a hospital setting where monitoring is possible and resuscitation equipment is available.

This medicine must only be used by parents/carers where the child has been diagnosed to have epilepsy.

2. What you need to know before you give Midazolam
Do not give Midazolam if the patient has:
  • An allergy to midazolam, benzodiazepines (such as diazepam) or any of the other ingredients of this medicine (listed in section 6)
  • A disease of the nerves and muscles causing muscle weakness (myasthenia gravis)
  • Severe difficulty breathing at rest (Midazolam can make breathing difficulties worse)
  • An illness causing frequent interruption of breathing during sleep (sleep apnoea syndrome)
  • Severe liver problems.

Warnings and precautions

Talk to your doctor or pharmacist before giving Midazolam if the patient has:

  • A kidney, liver or heart condition
  • A lung condition that causes difficulty breathing on a regular basis.

This medicine may cause people to forget what happened after they have been given it. Patients should be observed carefully after being given the medicine.

This medicine should be avoided in patients with a medical history of alcohol or drug abuse.

Life threatening incidents are more likely in patients with breathing difficulties or heart problems, especially when higher doses of Midazolam are given.

Children younger than 3 months: Midazolam should not be given to children younger than 3 months since there is not enough information in this age group.

If you are not sure if any of the above applies to the patient, talk to a doctor or pharmacist before giving this medicine.

Other medicines and Midazolam

Tell your doctor or pharmacist if the patient is taking, or has recently taken, or might take any other medicines. If you have any doubt about whether any medicine the patient is taking may affect the use of Midazolam, please speak to your doctor or pharmacist.

This is extremely important, as using more than one medicine at the same time can strengthen or weaken the effect of the medicines involved.

The effects of Midazolam may be intensified by medicines such as:

  • antiepileptics, (for treating epilepsy) e.g. phenytoin
  • antibiotics, e.g. erythromycin, clarithromycin
  • antifungals, e.g. ketoconazole, voriconazole, fluconazole, itraconazole, pozaconazole
  • anti-ulcer medicines, e.g. cimetidine, ranitidine and omeprazole
  • medicines used to treat blood pressure, e.g. diltiazem, verapamil
  • some medicines used to treat HIV and AIDS, e.g. saquinavir, lopinavir/ritonavir combination
  • narcotic analgesics (very strong pain killers), e.g. fentanyl
  • medicines used to reduce fat in the blood, e.g. atorvastatin
  • medicines used to treat nausea, e.g. nabilone
  • hypnotics (sleep inducing medicines)
  • sedative antidepressants (medicines used to treat depression that make you sleepy)
  • sedatives (medicines that relax you)
  • anaesthetics (for pain relief)
  • antihistamines (to treat allergies).

The effects of Midazolam may be reduced by medicines such as:

  • rifampicin (used to treat tuberculosis)
  • xanthines (used to treat asthma)
  • St John’s Wort (a herbal medicine). This should be avoided in patients taking Midazolam.

Midazolam may increase the effect of some muscle relaxants e.g. baclofen (causing increased drowsiness). This medicine may also stop some other medicines from working as well, e.g. levodopa (used to treat Parkinson’s disease).

Talk to your doctor or pharmacist about medicines the patient should avoid whilst taking Midazolam.

Midazolam with food and drink

The patient must not drink alcohol while taking Midazolam. Alcohol may increase the sedative effects of this medicine and make them very sleepy.

The patient must not drink grapefruit juice while taking Midazolam. Grapefruit juice may increase the sedative effects of this medicine and make them very sleepy.

Pregnancy

If the patient who will be given this medicine is pregnant or breast-feeding, thinks she may be pregnant or is planning to have a baby, ask a doctor for advice before taking this medicine.

Giving high doses of Midazolam during the last 3 months of pregnancy can cause abnormal heart beat in the unborn child. Babies born after this medicine is administered during childbirth can also have poor suckling, breathing difficulties and poor muscle tone at birth.

Breast-feeding

Tell the doctor if the patient is breast-feeding. Even though small amounts of Midazolam may pass into breast milk, it may not be necessary to stop breast-feeding. The doctor will advise if the patient should breast-feed after being given this medicine.

Driving and using machines

The medicine can affect your ability to drive as it may make you sleepy or dizzy.

  • Do not drive while taking this medicine until you know how it affects you.
  • It is an offence to drive if this medicine affects your ability to drive.
  • However, you would not be committing an offence if:
    • The medicine has been prescribed to treat a medical or dental problem and
    • You have taken it according to the instructions given by the prescriber or in the information provided with the medicine and
    • It was not affecting your ability to drive safely

Talk to you doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

Midazolam may make the patient sleepy, forgetful or affect their concentration and co-ordination. This may affect their performance at skilled tasks such as driving, riding a bicycle, or using machines.

After receiving this medicine, the patient should not drive a vehicle, ride a bicycle or operate a machine until they have completely recovered. Please discuss with your doctor if you need further advice.

Midazolam contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per oral syringe, that is to say essentially ‘sodium-free’.

3. How to give Midazolam

Always give this medicine exactly as a doctor has told you. Check with a doctor or pharmacist if you are not sure.

Dosage

Your doctor will prescribe the appropriate dose of Midazolam your child needs, generally according to your child’s age. The different doses each have a different colour, which is shown on the carton, the tube and the syringe containing the medicine.

Depending on age, your child will have received one of the following doses, in specifically colour labelled packaging:

3 months to less than 1 year: 2.5 mg - yellow labelled packaging

1 year to less than 5 years: 5 mg - blue labelled packaging

5 years to less than 10 years: 7.5 mg - purple labelled packaging

10 years to less than 18 years: 10 mg - orange labelled packaging

The dose is the full contents of one oral syringe. Do not give more than one dose.

Toddlers aged from 3 months to less than 6 months should only be treated in a hospital setting where monitoring is possible and resuscitation equipment is available.

Preparing to give this medicine

If the child is having a seizure, allow their body to move freely, do not try to restrain them. Only move them if they are in danger from, for example, deep water, fire or sharp objects.

Support your child’s head with something soft, such as a cushion or your lap.

Check that the medicine is the correct dose for your child, according to their age.

How to give this medicine

Ask a doctor, pharmacist or nurse to show you how to take or administer this medicine. Always check with them if you are not sure.

The information on how to give this medicine is also shown on the tube label.

Midazolam must not be injected. Do not attach a needle to the syringe

Step 1

Hold the plastic tube and pull the cap off. Take the syringe out of the tube.

Step 2

Step 3

Step 4

Slowly press the syringe plunger until the plunger stops. The full amount of solution should be inserted slowly into the space between the gum and the cheek (buccal cavity). If necessary (for larger volumes and/or smaller patients), approximately half the dose should be given slowly into one side of the mouth, then the other half given slowly into the other side.

  • The child’s breathing slows down or stops e.g. slow or shallow breathing or blue lips
  • You observe signs of a heart attack which may include chest pain or pain that spreads to the neck and shoulders and down the left arm

    • Absence of knee reflex or a response to a pinch
    • Breathing difficulties (slow or shallow breathing)
    • Low blood pressure (giddiness and feeling faint)

Do not give more than the amount of medicine prescribed by a doctor for the patient.

If the child is sick (vomits)

  • Do not give the patient another dose of Midazolam.
  • If the seizure does not stop within 10 minutes, call an ambulance.

If you have any further questions on the use of this medicine, ask a doctor or pharmacist.
