How does diazepam work? Diazepam belongs to a group of medicines called benzodiazepines.
It works by increasing the levels of a calming chemical in your brain.
Depending on your health condition, this can make you feel drowsy, relieve anxiety, stop seizures or relax tense muscles.
8. Cautions with other medicines
Some medicines interfere with the way diazepam works and increase the chances of you having side effects.
Before you start taking diazepam, tell your doctor if you’re taking :
- antipsychotics used to treat mental health problems
- antidepressants used to treat depression
- anticonvulsants used to treat epilepsy
- hypnotics used to treat anxiety or sleep problems
- drowsy or sedating antihistamines, such as chlorphenamine or promethazine

Mixing diazepam with herbal remedies or supplements
There’s very little information about taking herbal remedies and supplements with diazepam.
Do not take herbal medicines for anxiety or insomnia, such as valerian or passionflower, with diazepam.
They can increase the drowsy effects of diazepam and may also have other side effects
