How Does Dalmane Work?

Flurazepam belongs to the benzodiazepine class of drugs. It binds to receptors in the brain that help with sleep and anxiety. When these receptors get activated, they send signals to the body’s central nervous system, causing relaxation and calmness.

When taken at bedtime, Dalmane helps people fall asleep faster and for a long time. Dalmane has a half-life of about 2.5 hours, but patients will feel its effect within 15 minutes, and it will last for about 6 hours.

Doctors can also recommend Dalmane for people who wake up too early or suffer from conditions requiring them to get restful sleep. Sleep laboratory studies have determined that Dalmane is effective for at least 28 nights consecutively when used correctly.

Using Dalmane Medication

Dalmane is available in the form of capsules that should be taken by mouth. Adults can take between 15-30 mg per day, while older people should not take more than 15 mg of flurazepam before bed.
