Beer and Flurazepam

Here is the interaction we found between these two, with the evidence behind it.

Major

CNS DEPRESSANTS

Why this applies to Flurazepam

Flurazepam falls under CNS DEPRESSANTS — the group Beer interacts with.

Concomitant use may increase sedative and other adverse effects.
Concomitant use of alcohol with CNS depressants can increase sedative and other adverse effects, potentially through inhibition of the metabolism of certain CNS depressants.
Severity Major Likelihood Likely Evidence C

Well-controlled human studies have demonstrated the likely existence of this interaction.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: both beer and flurazepam calm down your brain. Flurazepam already slows brain activity to help you sleep, and alcohol pushes in the same direction. Add them together and the effects stack on top of each other. Alcohol can also slow down how your body clears the medication, so more of it lingers in your system.

In real life, that can mean heavy drowsiness, dizziness, confusion, poor coordination, memory gaps, and dangerously slowed breathing. Older adults are especially at risk for falls. This combo is considered a serious one, so please don't pair beer with flurazepam without talking to your pharmacist or doctor first about what's safe for you.

From our pharmacist’s overview on the Flurazepam page

“Beer and wine sit at the top of this list for good reason. Alcohol taken with flurazepam (Dalmane), a long-acting benzodiazepine sleep medicine, can deepen sedation dangerously, a major-rated and well documented interaction.”

About Beer

What is Beer?

Beer
  • Social and recreational drinking
  • Relaxation
  • Heart health (popular belief)
  • Bone health (popular belief)
  • Source of antioxidants and B vitamins

Beer is an alcoholic beverage that contains some minerals, B vitamins, and plant compounds from hops and grain, but it is not a health supplement. Any possible benefits come only from light-to-moderate intake, and they are easily outweighed by the well-known harms of alcohol. The safest amount of alcohol for health is none, and beer should be avoided in pregnancy and breastfeeding.

About Flurazepam

What Is Flurazepam Used For?

Brand names: Dalmane, Somnol, Apo-Flurazepam, Bio-Flurazepam, Novo-Flurazepam, PMS-Flurazepam, Som Pam

Flurazepam Hydrochloride capsules are used to treat insomnia. Specifically, they help with difficulty falling asleep, frequent wake-ups during the night, and early morning awakening.

Because insomnia is often short-lived, flurazepam is generally intended for short-term use. If sleep problems don't improve within 7 to 10 days of treatment, a healthcare provider should evaluate whether an underlying medical or psychiatric condition may be the cause.
