1. What Midazolam is and what it is used for
Midazolam is one of a group of medicines known as
benzodiazepines. Benzodiazepines are sedatives, meaning that
they are used to relax you and help you to sleep.
Midazolam Injection is used to help you feel relaxed and to help
you sleep before and during an operation. It can also calm you
during an operation where you are not asleep. It may also be
used to help patients in intensive care units to relax.

2. Before Midazolam is given
You should not be given Midazolam:
• If you are allergic or hypersensitive to Midazolam or other or
to any of the ingredients in the product.
• If you have severe breathing difficulties or problems with
your lungs
Take special care with Midazolam if:
• you have severe or moderate breathing difficulties
• you are over 60 years of age
• it is to be given to children, especially those suffering heart
or blood vessel problems (cardiovascular)

‘Pregnancy and breast-feeding’).
If any of the above applies to you, please tell your doctor.

any other medicines, including medicines obtained without a

voriconazole, ketoconazole or posaconazole

• Medicines to treat high cholesterol, such as Atorvastatin

Pregnancy and breast-feeding:
This medicine should not be used during pregnancy unless your
doctor feels it is necessary.
Midazolam passes in low amounts into breast milk. Nursing
mothers are advised to stop breast-feeding for 24 hours following
administration of midazolam
Please speak to your doctor if you are pregnant, trying to become
pregnant or are breast-feeding.
Driving and using machinery:
This medicine may adversely affect your ability to drive or use
machines. You should not drive a vehicle or operate a machine
until completely recovered. Your physician should decide when
these activities may be resumed. It is recommended that you are
accompanied when returning home after you are discharged
from hospital.
Important information about some of the ingredients of
Midazolam injection is essentially ‘sodium free’ as it contains less
than 1mmol sodium (23mg) per ampoule.

3. How Midazolam is given
Adults and the elderly.
Midazolam Injection will be given to you by a doctor or nurse
slowly in a vein (intravenous) either as a continuous infusion or
intermittent bolus injection or into a muscle. Your doctor will
decide the correct dosage for you as this would be dependent on
your general physical condition, age, weight and your response
to treatment and whether other medicines are needed at the
same time.
The precise dose and route of administration must be decided by
a doctor qualified in the treatment of children.

If you are given too much Midazolam:
As this medicine will be given to you whilst you are in hospital it
is unlikely that you will be given too little or too much, however,
tell your doctor, nurse or pharmacist if you have any concerns.

• Rush and itching
• Muscle tremor
If any of the side effects get serious, or you notice any side effects
not listed in the leaflet, please tell your doctor or pharmacist.

If you stop taking Midazolam
During prolonged treatment with Midazolam, physical
dependence may develop. Suddenly stopping the treatment may
be accompanied by withdrawal symptoms. The following
symptoms may occur: headaches, muscle pain, anxiety, tension,
restlessness, confusion, irritability, rebound insomnia (unable to
sleep), mood changes, hallucinations and convulsions. Since the
risk of withdrawal symptoms is greater after suddenly stopping
