Brand Name: Dalmane

What is Dalmane (flurazepam)?

Flurazepam is a benzodiazepine (ben-zoe-dye-AZE-eh-peen) similar to Valium. Flurazepam affects chemicals in the brain that may be unbalanced in people with sleep problems (insomnia).

Flurazepam is used to treat symptoms of insomnia, such as trouble falling or staying asleep.

Flurazepam may also be used for purposes not listed in this medication guide.

What is the most important information I should know about Dalmane (flurazepam)?

Some people using this medicine have engaged in activity such as driving, eating, walking, making phone calls, or having sex and later having no memory of the activity.

What should I discuss with my healthcare provider before taking Dalmane (flurazepam)?

You should not use flurazepam if you are allergic to it, or if you are pregnant.

To make sure flurazepam is safe for you, tell your doctor if you have:

  • depression or mental illness;

  • a history of drug or alcohol addiction;

  • a history of suicidal thoughts or actions; or

  • if you use a narcotic (opioid) medication.

Flurazepam may cause breathing problems, feeding problems, and low body temperature in a newborn. Your baby could also become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant. Use effective birth control to prevent pregnancy while you are taking flurazepam.

It is not known whether flurazepam passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

The sedative effects of flurazepam may last longer in older adults. Accidental falls are common in elderly patients who take benzodiazepines. Use caution to avoid falling or accidental injury while you are taking flurazepam.

How should I take Dalmane (flurazepam)?

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Flurazepam may be habit forming. Never share flurazepam with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

Take flurazepam only if you are able to get a full night's sleep before you must be active again. Never take this medicine during your normal waking hours, unless you have at least 7 to 8 hours to dedicate to sleeping.

Call your doctor if your insomnia does not improve after taking flurazepam for 7 to 10 nights, or if you have any mood or behavior changes. Insomnia can be a symptom of depression, mental illness, or certain medical conditions.

Do not stop using flurazepam suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using flurazepam.

Your insomnia symptoms may return when you stop using flurazepam after using it over a long period of time. You may need to use less and less before you stop the medication completely.

Store at room temperature away from moisture, heat, and light.

Keep track of the amount of medicine used from each new bottle. Flurazepam is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.

What happens if I miss a dose?

Since flurazepam is taken as needed, you are not likely to be on a dosing schedule. Take flurazepam only when you have time for several hours of sleep.
