1. What midazolam is and what it is used for
Midazolam 1 mg/ml & 5 mg/ml Solution for Injection or Infusion contains Midazolam. Midazolam belongs to a group of medicines known as benzodiazepines (sedatives).
It is a short acting medicine that is used to induce sedation (a state of calm, drowsiness or sleep) and relieves anxiety, muscle tension. It has anticonvulsant effects and causes anterograde amnesia. This medicine is used for:
- Conscious sedation (state of calm or drowsiness where you remain awake) in adults and children
- Sedation in intensive care units in adults and children.
- Anaesthesia in adults (premedication before induction, induction of anaesthesia, as a sedative component with other medicines in anaesthesia)
- Premedication before induction of anaesthesia in children.
2. What you need to know before you take midazolam
Do not use midazolam
• If you are allergic (hypersensitive) to midazolam, group of medicines known as benzodiazepines or any of the midazolam solution for injection
• If you have severe difficulties with your breathing and that you are to undergo conscious sedation.
Take Special Care with midazolam
Midazolam should be used only when age- and size-appropriate resuscitation facilities are available. Administration of midazolam may depress myocardial contractility and cause apnoea (suspension of breathing). Severe cardio respiratory adverse events have occurred on rare occasions. These have included respiratory depression, apnea, respiratory and/or cardiac arrest. To avoid such incidents, the injection should be given slowly and the dose should be as low as possible.
Special care needs to be taken if midazolam is used in babies or children. Let your doctor know if your child has a cardiovascular disease. Your child will be carefully monitored and the dose will be adjusted specially. Patients under 6 months old in sedation in Intensive Care Unit are more likely to develop breathing problems, so they will be dosed very gradually and their breathing and oxygen levels observed.
When midazolam is given as a premedication, you will be checked closely to how you respond and to ensure you have received the right dose as the sensitivity varies depending of the patient.
The use of midazolam is not recommended in neonates and children up to 6 months of age.
Paradoxical reactions and anterograde amnesia (loss of memory for recent events) have been reported to occur with midazolam (see section 4. Possible Side Effects).
Let your doctor know if you:
- are over 60 years of age
- have a long term illness or are debilitated (for example, chronic respiratory problems, renal, hepatic or cardiac disorders).
- have a myasthenia gravis (neuromuscular disease characterized by a muscle weakness).
- have a history of alcohol or drug abuse.
- are taking any other medicines including those not prescribed by your
doctor (for more information see section 'Using other medicines')
- are pregnant or think be pregnant.
Long term treatment
If you receive long-term midazolam, you may become tolerant (midazolam becomes less effective) or you may be become dependent upon this medicine. After treatment for a long time (such as in an intensive care unit) the following withdrawal symptoms may occur: headaches, muscle pain, anxiety, tension, restlessness, confusion, irritability, inability to sleep, mood changes, hallucinations and convulsions. Your doctor will reduce your dose gradually to avoid these effects happening to you.
Using other medicines:
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
This is extremely important, as using more than one medicine at the same time can strengthen or weaken the effect of the medicines involved.
In particular, tell your doctor or nurse if you are taking any of the following medicines:
• tranquilisers (for anxiety or to help you sleep)
• hypnotics (medicines to make you sleep)
• sedatives (to make you feel calm or sleepy)
• nefazodone and other antidepressants (medicines for depression)
• narcotic analgesics (very strong pain killers)
• antihistamines (used to treat allergies)
• medicines to treat fungal infections (ketoconazole, voriconazole, fluconazole, itraconazole, posaconazole)
• macrolide antibiotics (such as erythromycin, clarithromycin or roxithromycin)
• diltiazem, verapamil (used to treat high blood pressure)
• medicines for HIV called protease inhibitors (such as saquinavir)
• atorvastatin (used to treat high cholesterol)
• aprepitant (medicine for prevention of chemotherapy-induced nausea and vomiting)
• rifampicin (used to treat mycobacterial infections such as tuberculosis)
• carbamezapine or phenytoin (used to treat epileptic seizures and nerve pain)
• efavirenz (used to treat Human immunodeficiency virus)
• the herbal medicine St. John's Wort.
If any of the above apply to you, or if you are not sure, talk to your doctor or nurse before you are given Midazolam.
Operations
If you are going to have an inhaled anaesthetic (one that you breathe in) for an operation or for dental treatment, it is important to tell your doctor or dentist that you have been given Midazolam.
Using midazolam with food and drink
While you are using midazolam you must not drink any alcohol, since alcohol can markedly increase the sedative effect of midazolam.
Pregnancy and breast-feeding and fertility:
• If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. If your doctor decides that you should be given this medicine during late pregnancy, labour or caesarean section, you might have an inhalation risk and your baby might have an irregular heart beat, hypotonia (state of low muscle tone), feeding difficulties, a low body temperature and respiratory depression.
• If you have passed through prolonged treatment during last phase of pregnancy with this medicine, your baby may develop physical dependence and risk of withdrawal symptoms after birth.
• Midazolam may pass into breast milk, therefore, if you are breast feeding you should not do so for 24 hours after receiving this medicine.
Driving and using machines:
This medicine may make you sleepy, forgetful, dizzy or affect your concentration and co-ordination.
• Do not drive while taking this medicine until you know how it affects you.
This may affect your performance at skilled tasks, e.g. driving or operating machinery.
• After midazolam administration you should not drive a vehicle or operate a machine until completely recovered. Your doctor should advise you when you can start these again.
• You should always be accompanied to home by a responsible adult after your treatment.
• 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 your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.
Important information about some of the ingredients of midazolam solution for injection
This medicinal product contains less than 1 mmol sodium (23 mg) per dose i.e. essentially 'sodium free'.
3. How to use midazolam
Midazolam should be administered only by experienced physicians in a setting fully equipped for the monitoring and support of respiratory and cardiovascular function and by persons specifically trained in the recognition and management of expected adverse events.
Instructions for proper use
Midazolam is compatible with the following infusion solutions:
- sodium chloride 9 mg/ml (0.9 %) solution
- 5 % dextrose solution
- 10 % dextrose solution
- Fructose 50 mg/ml (5 %) solution
- Ringer solution
- Hartmann's solution
Do not dilute midazolam solutions with 6% w/v dextran (with 0.9% sodium chloride) in dextrose.
Do not mix midazolam ampoule solutions in alkaline injections.
Midazolam precipitates in sodium bicarbonate.
To avoid potential incompatibility with other solutions, midazolam ampoule solution must not be mixed with other solutions except those mentioned above.
Dosage and route of administration
Your doctor will decide on a suitable dose for you. Doses vary considerably and will depend on the planned treatment and the sedation required. Your weight, age, general condition of health, concomitant medication, response to the drug and whether other medicines are required at the same time will also influence the dose that you receive.
If you are to receive strong painkillers, you will receive these first and then have your midazolam dose adjusted specially for you.
Midazolam is given slowly, by injection into a vein (intravenously), by a drip (infusion), injection into a muscle (intramuscular) or via rectal administration.
Midazolam ampoules are for single use only. Discard any unused solution.
The solution should be visually inspected prior to use. Only clear solutions without particles should be used.
If you use more midazolam than you should
Your medicine will be given by a doctor.
If you accidentally got an overdose, this could lead to sleepiness, ataxia (in coordination of voluntary muscular action), dysarthria (speech disorder) and nystagmus (involuntary eye movements), loss of reflexes, apnoea (suspension of breathing), hypotension (low blood pressure), cardio respiratory depression and coma. Overdose may require intense vital sign monitoring and symptomatic treatment of cardio respiratory effects and use of benzodiazepine antagonist.
If you stop using midazolam
Sudden discontinuation of treatment will therefore be accompanied by withdrawal symptoms such as headache, muscular pain, anxiety, tension, restlessness, confusion, mood swings, hallucinations & convulsions, rebound insomnia, irritability and convulsions. Since the risk of withdrawal symptoms occurring is greater if treatment is discontinued abruptly, dose should be reduced gradually when treatment is being discontinued.
