Diazepam is a benzodiazepine sedative primarily used to alleviate anxiety symptoms, control epileptic seizures, and relax muscles. It enhances the effect of the inhibitory neurotransmitter GABA in the brain, resulting in a calming effect on the nervous system.
Clinical applications include treatment for acute and chronic anxiety disorders, pre- and post-operative sedation, and alcohol withdrawal symptoms. Its long duration of action and rapid onset make it one of the preferred emergency medications.
The generic name of this drug is Diazepam. Major brand names include:
Available in various formulations including tablets, injections, and rectal gels for children, which should be selected based on the specific symptoms.
Diazepam belongs to the benzodiazepine class of drugs, which have anxiolytic, muscle relaxant, anticonvulsant, and sedative properties. Its chemical structure and mechanism of action are similar to other benzodiazepines.
Main indications include:
It is also used for muscle spasms, tetanus symptom relief, and management of alcohol withdrawal symptoms.
Minor side effects may include:
These symptoms usually diminish after adapting to the medication; if they persist, inform your doctor.
Contraindications: Not for use in individuals allergic to benzodiazepines, patients with myasthenia gravis, or severe respiratory failure. Use during breastfeeding may affect the infant and should be evaluated carefully.
Pregnant women require special caution, especially in early pregnancy where there may be an increased risk of congenital abnormalities. Use only if necessary. Elderly patients over 65 are prone to mental confusion and dosage adjustments are necessary.
Combining with alcohol or other sedatives (such as morphine or sleeping pills) can enhance sedative effects and may cause respiratory depression. Combining with anticoagulants (like warfarin) may increase bleeding risk.
Avoid concurrent use with certain antifungal medications (such as itraconazole), which may increase diazepam blood levels. Always consult your doctor before using any prescription or over-the-counter drugs.
For adult anxiety, the initial dose is typically 5-10 mg per dose, 2-4 times daily; for seizure control, a single dose of 10-30 mg intravenously may be required. Pediatric doses should be calculated based on weight; rectal formulations are suitable for patients with epilepsy who cannot take oral medication.
Swallow tablets whole; do not chew or break them. Injections must be administered by healthcare professionals; do not adjust the dose yourself. Long-term use for anxiety should not exceed 4 weeks to avoid dependency.
If a dose is missed, take it as soon as remembered unless the next dose is due within 4 hours. Do not double doses to make up for missed ones to prevent overdose.
Overdose can cause deep coma, respiratory depression, or death. Seek immediate medical attention and inform healthcare providers of the amount taken. Flumazenil may be used as an antidote.
Store in a locked container out of reach of children. Overdose requires emergency assessment and treatment to prevent life-threatening complications.
