If you are in an intensive care unit, you may receive an infusion of Midazolam Sandoz over several hours or days as a sedative.

Ask your doctor if you have any questions about why Midazolam Sandoz has been prescribed for you.

Symptoms of an allergic reaction may include asthma, wheezing or shortness of breath, swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing, hives, itching or skin rash or fainting.

1. you are pregnant, or intend to become pregnant.

Like most medicines, Midazolam Sandoz is not recommended for use during pregnancy. Your doctor will discuss the possible risks and benefits of using Midazolam Sandoz during pregnancy.

2. you are breast-feeding or intend to breast-feed.

Midazolam Sandoz passes into breast milk and therefore there is a possibility that the breast-fed baby may be affected. Midazolam Sandoz is not recommended for use while breast-feeding. Your doctor will discuss the risks and benefits of using Midazolam Sandoz when breast-feeding.

epilepsy (fits or convulsions)
high or low blood pressure

Alcohol should be avoided for at least 12 hours after receiving Midazolam Sandoz. Combining alcohol and Midazolam Sandoz may make you more sleepy, dizzy or lightheaded.

5. you are allergic to any other medicines, foods, dyes or preservatives.

If you have not told your doctor about any of the above, tell them before you use any Midazolam Sandoz.

How Midazolam Sandoz is given

Midazolam Sandoz is given by an injection into a vein or muscle.
It may also be given through an infusion set in an intensive care unit. Other medicines may also be given at the same time.
Your anaesthetist will decide what dose and how long you will receive Midazolam Sandoz. The dose of Midazolam Sandoz will be adjusted to keep you at the right depth of sleep or sedation. Lower doses may be given to elderly patients.
Midazolam Sandoz may be given once before a medical procedure, or continuously by infusion for patients in an intensive care unit.

If you have been given too much (overdose)

As Midazolam Sandoz is given to you under the supervision of your doctor, it is very unlikely that you will receive too much. However, if you experience any side effects after being given Midazolam Sandoz, tell your doctor immediately or go to Accident and Emergency at your nearest hospital. You may need urgent medical attention.
If you have received too much Midazolam Sandoz, you may feel drowsy, tired, confused, dizzy, weak or become unconscious.

While you are receiving Midazolam Sandoz

Your anaesthetist, surgeon and nursing staff are trained to look after every need that you have while you are asleep or sedated. If you are receiving Midazolam Sandoz for general anaesthesia, the anaesthetist may need to use several different medicines to keep you asleep, pain free, breathing in a healthy way and with good blood pressure.
If you are receiving Midazolam Sandoz for sedation, other drugs are given at the same time. The mix and doses of drugs needs to be chosen by specially trained doctors and adjusted for each patient according to their need.

Things you must do

Tell your doctor if you feel Midazolam Sandoz is not helping you.

Things you must not do

After receiving Midazolam Sandoz your ability to drive a car or to operate machinery may be affected for some time. Therefore, if you are able to go home soon after your operation, do not drive a car or operate machinery. This is important. Ask your doctor when you can return to activities such as driving a vehicle or operating machinery.
Do not have any alcohol for at least 12 hours after you have been given Midazolam Sandoz.

Things to be careful of

Be careful if you are elderly as you may be at an increased risk for falls and fractures.

Side effects

Tell your doctor, nurse or pharmacist as soon as possible if you do not feel well after you have received Midazolam Sandoz.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.
Some of the unwanted side effects of Midazolam Sandoz are the result of sleep being too light or too deep. Your anaesthetist will reduce the dose of Midazolam Sandoz if your blood pressure is low, or if you need help breathing. However, your anaesthetist may increase the dose if body movement is still observed. Other medicines may also be needed if your heart rate becomes too slow or irregular.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor or nurse if you notice any of the following and they worry you:
drowsiness, tiredness
dizziness, unsteadiness
loss of memory, inattentiveness, confusion, lack of concentration
headache, hangover feeling in the morning
slurred speech
unpleasant dreams
blurred vision
pain, redness or hardness at the injection site
muscle stiffness or inflammation of the vein
headache, hiccups
feeling sick with or without vomiting
Tell your doctor or nurse immediately or go to Accident and Emergency at your nearest hospital if you notice any of the following:
skin rash
asthma, wheezing or shortness of breath
change in pulse rate or blood pressure
swelling of the face, lips, tongue or throat which may cause difficulty in swallowing or breathing
sudden anxiety or excitation
hallucinations or delusions
severe sleep disturbances.
These are serious side effects. You may need urgent medical attention. Serious side effects are rare.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything that is making you feel unwell.
Do not be alarmed by this list of possible unwanted side effects. You may not experience any of them.
