Description

Midazolam (MID-ay-zoe-lam) is used to produce sleepiness or drowsiness and to relieve anxiety before surgery or certain procedures. It is also used to produce loss of consciousness before and during surgery. Midazolam is used sometimes in patients in intensive care units in hospitals to cause unconsciousness. This may allow the patients to withstand the stress of being in the intensive care unit and help the patients cooperate when a machine must be used to assist them with breathing.

Midazolam is given only by or under the immediate supervision of a doctor trained to use this medicine. If you will be receiving midazolam during surgery, your doctor or anesthesiologist will give you the medicine and closely follow your progress.

Midazolam is available in the following dosage forms:


Before Using This Medicine

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For midazolam, the following should be considered:

Allergies--Tell your doctor if you have ever had any unusual or allergic reaction to midazolam or other benzodiazepines (such as alprazolam [e.g., Xanax], bromazepam [e.g., Lectopam], chlordiazepoxide [e.g., Librium], clonazepam [e.g., Klonopin], clorazepate [e.g., Tranxene], diazepam [e.g., Valium], estazolam [e.g., ProSom], flurazepam [e.g., Dalmane], halazepam [e.g., Paxipam], ketazolam [e.g., Loftran], lorazepam [e.g., Ativan], nitrazepam [e.g., Mogadon], oxazepam [e.g., Serax], prazepam [e.g., Centrax], quazepam [e.g., Doral], temazepam [e.g., Restoril], triazolam [e.g., Halcion]). Also, tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy--Midazolam is not recommended for use during pregnancy because it may cause birth defects. Other benzodiazepines, such as chlordiazepoxide (e.g., Librium) and diazepam (e.g., Valium) that are related chemically and in action to midazolam, have been reported to increase the chance of birth defects when used during the first 3 months of pregnancy. Also, use of midazolam during pregnancy, especially during the last few days, may cause drowsiness, slow heartbeat, shortness of breath, or troubled breathing in the newborn infant. In addition, receiving midazolam just before or during labor may cause weakness in the newborn infant.

Breast-feeding--Midazolam passes into breast milk. Because newborn babies may be especially sensitive to the effects of midazolam, you should discuss breast-feeding with your physician if you are going to receive midazolam. It may be advisable to stop breast-feeding for a short period of time after receiving midazolam.

Children--Newborn babies may be especially sensitive to the effects of midazolam. This may increase the chance of side effects during the use of this medicine. Also, time to complete recovery after midazolam is given may be longer in very ill newborn babies.

Older adults--Elderly people are especially sensitive to the effects of midazolam. This may increase the chance of side effects during the use of this medicine. Also, time to complete recovery after midazolam is given may be slower in the elderly than in younger adults.

Other medicines--Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving midazolam, it is especially important that your health care professional know if you are taking any of the following:

Other medical problems--The presence of other medical problems may affect the use of midazolam. Make sure you tell your doctor if you have any other medical problems, especially:


Proper Use of This Medicine

Dosing--The dose of midazolam will be different for different patients. Your doctor will decide on the right amount for you. The dose will depend on:


Precautions After Receiving This Medicine

Side Effects of This Medicine

Along with its needed effects, a medicine may cause some unwanted effects. While you are receiving midazolam your doctor will monitor you closely for the side effects of midazolam, for example, breathing problems and confusion.

Some side effects may occur that usually do not need medical attention. Most side effects will go away as the effects of midazolam wear off.

However, check with your doctor if any side effects continue or are bothersome.
