What the word means
Zaleplon is the drug. Sonata is the brand.
It’s the shortest-acting of the Z-drugs, with a very brief half-life. That single property defines it. It’s built for the problem of not being able to fall asleep, and because it clears so quickly, it tends to leave less of a hangover the next morning than its longer-acting relatives.
The flip side is that it does less for staying asleep, since it’s mostly gone by the middle of the night. It’s a controlled substance and it’s meant for short-term use.

When to seek professional care
Take it only when you can give yourself enough time to sleep, and never with alcohol. Tell your prescriber right away if you learn you’ve done anything while asleep that you don’t remember. For insomnia that has lasted months, ask about CBT for insomnia rather than staying on a sleeping pill indefinitely. If you have thoughts of harming yourself, get help right away by calling 911, or call or text 988 in the US to reach the Suicide and Crisis Lifeline.
