diazepam rectal gel
How does this medication work? What will it do for me?
Diazepam belongs to the class of medications called benzodiazepines. It is used for the intermittent treatment of severe seizures (also known as recurrent, serial, cluster, or crescendo seizures) that occur for certain people even though they take regular doses of medications to treat epilepsy.
Diazepam rectal gel usually starts controlling seizures 5 to 15 minutes after it is used. It works by slowing down the nerves in the brain (i.e., the central nervous system). This medication is used to treat those who experience an increase in their seizure frequency at home, in hospitals, in emergency units, or in residential institutions.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.
What form(s) does this medication come in?
Each rectal delivery system of clear to slightly yellow, non-sterile gel, with a pH between 6.5 to 7.2, contains diazepam 5 mg/mL. Nonmedicinal ingredients: benzoic acid, benzyl alcohol (1.5%), ethyl alcohol (10%), hydroxypropyl methylcellulose, propylene glycol, sodium benzoate, and water.
How should I use this medication?
The dose of diazepam rectal gel will be determined for each individual according to weight and age.
For children 2 to 5 years of age, the dose is 0.5 mg per kilogram of body weight. For children 6 to 11 years of age, the dose is 0.3 mg per kilogram. For ages 12 and over, the recommended dose is 0.2 mg per kilogram.
Since the dose of diazepam rectal gel is available in fixed unit doses of 5 mg, 10 mg, 15 mg, and 20 mg only, the prescribed dose is obtained by rounding upward to the next available dose. For seniors, it is recommended that the dosage be rounded downwards.
If a single dose does not adequately treat the seizure, your doctor may wish to prescribe 2 doses of diazepam rectal gel. The second dose may be given 4 to 12 hours after the first dose if seizures continue or are known to recur, or if the patient is known to have seizures that are especially resistant to treatment.
Treatment with diazepam rectal gel should be given no more than every 5 days, and no more than 5 times per month.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Alcohol and other medications that cause drowsiness: Alcohol and other medications that cause drowsiness, such as antidepressants, sleeping pills, anxiety medications, or narcotic pain relievers, should be avoided when you are taking diazepam. Combining any of these medications with diazepam can result in severe drowsiness, breathing problems, and possibly coma and death. People who have an addiction to alcohol or other medications should not take diazepam, except in rare situations under medical supervision.
Breathing problems: Diazepam can breathing problems. People with chronic lung conditions, such as bronchitis, emphysema, or asthma, may be more likely to experience increased difficulty breathing. If you have lung problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Dependence and withdrawal: Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with benzodiazepines such as diazepam. Severe withdrawal symptoms may occur if the dose is significantly reduced or suddenly discontinued. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms.
Falls and fractures: Diazepam can cause drowsiness or dizziness that can affect your balance and increase your risk of falling. This can result in fractures or other injuries. Your risk of falls is increased if you drink alcohol or take sedatives while taking this medication, if you are elderly, or if you have a condition that causes weakness or frailty.
Drowsiness/reduced alertness: Because diazepam causes drowsiness and sedation, do not engage in activities requiring mental alertness such as driving a car or operating machinery until the sedating effects of this medication have worn off. Alcohol can increase the drowsiness effects and should be avoided.
Kidney function: Kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects. If you have kidney problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately. Diazepam may cause harm to the developing baby if it is used by the mother while she is pregnant. Babies born to mothers who have used diazepam regularly during late pregnancy may have breathing difficulties and show signs of withdrawal when they are first born.
Breast-feeding: Diazepam passes into breast milk. Diazepam rectal gel should not be used by women who are breast-feeding.
Children: The safety and effectiveness of diazepam rectal gel for children under 2 years of age have not been established.
Seniors: The dose of diazepam rectal gel may need to be decreased for those over 60 years of age to avoid excessive sleepiness and impaired coordination.
