Clonazepam

Mental health

Also known as Klonopin

Clonazepam is a benzodiazepine that quiets overactive signals in your brain by boosting a calming chemical called GABA. It sticks around in your body longer than alprazolam, so its effects are steadier and less of a rollercoaster. It's prescribed for panic disorder and some seizure conditions. It's a controlled substance — dependence can build even at prescribed doses, so it's meant to be used carefully and with a plan.

How to take it

When

Exactly as prescribed. Its effects last longer than most benzodiazepines, so daytime drowsiness is common at first.

Food

With or without food — whichever is comfortable for you.

Avoid

Never mix with alcohol, opioids, or other sedatives — the opioid combination can slow your breathing to the point of death. Don't drive until you know how it affects you.

Stopping

Never stop suddenly after regular use — withdrawal can include seizures. Your doctor will taper you down slowly.

Missed a dose?

Take it as soon as you remember, unless your next dose is coming up soon — then just skip the missed one. Never double up.

Common side effects

Drowsiness, especially during the day
Dizziness or feeling unsteady
Trouble with memory or focus
Feeling foggy or slowed down
Depression or mood changes
