1. What Miprosed is and what it is used for

Miprosed contains an active substance midazolam.

Midazolam is a member of a group of medicines called benzodiazepines which can help to relieve anxiety.

Midazolam is used for sedation and anxiolysis prior to diagnostic, surgical, therapeutic or endoscopic procedures and as a premedication before being induced for general anaesthesia in children aged between 6 months and 14 years.

2. What you need to know before you or your child use Miprosed

Do not give Miprosed if the patient has:

  • an allergy (hypersensitivity) to midazolam, to any other benzodiazepines (such as diazepam) or to any of the other ingredients of this medicine (listed in section 6)
  • severe liver disease
  • a disorder of the nerves or muscles that have severe muscle weakness (myasthenia gravis)
  • severe breathing problems
  • a condition that temporarily stops breathing during sleep (sleep apnea syndrome)

Do not use this medicine if any of the above apply to the patient. If you are not sure, talk to your doctor or pharmacist before using Miprosed.

Warnings and precautions

Miprosed 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 including respiratory and cardiac resuscitation.

Talk to the doctor, nurse or pharmacist before Miprosed is given if the person who is going to receive it:

  • has a mild, moderate or long-term illness (such as breathing, kidney, liver or heart problems)
  • has poor overall health
  • abuses or has in the past abused drugs or alcohol
  • is younger than 6 months.

Other medicines and Miprosed

Tell the doctor or pharmacist if the patient who is going to receive Miprosed is using, has recently used or might use any other medicines. This includes medicines obtained without a prescription, including herbal medicines. This is because Miprosed can affect the way some other medicines work. Also, some medicines can affect the way Miprosed works.

In particular, tell the doctor or nurse or pharmacist if the patient who is going to receive Miprosed is taking any of the following:

  • narcotic analgesics (e.g. fentanyl)
  • herbal medicines (e.g. St. Johns Wort)
  • medicines for epilepsy (e.g. carbamazepine, phenytoin)
  • medicines for high blood pressure and angina (e.g. diltiazem and verapamil)
  • medicines for indigestion, acid reflux or ulcer treatment (e.g. cimetidine, ranitidine and omeprazole)
  • medicines for asthma (e.g. theophylline, aminophylline and other xanthine’s)
  • medicines used to treat Parkinson’s disease (e.g. levodopa)
  • muscle relaxants (e.g. baclofen)
  • medicines used for nausea and/or vomiting (e.g. nabilone and aprepitant)
  • medicines for fungal infections (e.g. ketoconazole, voriconazole, fluconazole, itraconazole and posaconazole)
  • certain antibiotics (rifampicin, macrolide antibiotics e.g. erythromycin and clarithromycin)
  • medicines used to treat HIV called protease inhibitors (e.g. saquinavir)
  • medicines used for high cholesterol (e.g. atorvastatin)
  • medicines used to treat depression that make your child sleepy (sedative antidepressants)
  • other medicines for the treatment of depression (antidepressant, e.g. fluvoxamine)
  • medicines used for the treatment of involuntary urine loss (e.g. propiverine).

Using Miprosed together with other sedative/hypnotic medicines may cause increased sleepiness or breathing problems. Examples of sedative/hypnotic medicines include medicines used to treat mood or mental disorders, barbiturates, propofol, ketamine, etomidate, medicines used to treat allergies and some classes of medicine used to treat high blood pressure.

Concomitant use of Miprosed and opioids (strong pain killers, medicines for substitution therapy and some cough medicines) increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However, if the doctor does prescribe Miprosed together with opioids, the dose and duration of concomitant treatment should be limited by the doctor.

Please tell the doctor about all opioid medicines patient is taking and follow the doctor’s dose recommendation closely. It could be helpful to inform the patient’s friends or relatives to be aware of the signs and symptoms stated above. Contact the doctor when patient is experiencing such symptoms.

Do not use this medicine if any of the above apply to the patient. If you are not sure, talk to the doctor, nurse or pharmacist before using Miprosed.

Miprosed with food, drink and alcohol

Grapefruit juice and drinks containing caffeine should be avoided as they can affect the way that Miprosed works. The patient should not drink alcohol while taking Miprosed. Alcohol may increase the sedative effects of Miprosed and make the patient sleepier.

Pregnancy, breast-feeding and fertility

  • If your child is pregnant, thinks she might be pregnant or is planning to have a baby, then contact your child’s doctor before your child take this medicine
  • If your child is breastfeeding, she should be told not to breastfeed in the first 24 hours after taking Miprosed because midazolam passes into breast milk in small amount.

Driving and using machines

Miprosed may make the patient feel sleepy, forgetful, affect the level of concentration and reduce muscle function. This may negatively affect their performance at skilled tasks such as driving a vehicle or operating machinery.

After receiving this medicine, the patient should not drive or operate machinery until they have fully recovered.

Miprosed contains:

This medicine contains less than 1 mmol sodium (23 mg) in each ml of solution, that is to say essentially ‘sodium-free’.

If you give more Miprosed than you should
