Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Zaleplon (Sonata) and butabarbital (formerly known as Butisol) are both medications used to help with sleep. However, they belong to different medication classes. Zaleplon is a non-benzodiazepine sedative-hypnotic, often called a "z-drug," while butabarbital is a barbiturate. Zaleplon is still available as a prescription medication, but butabarbital has been discontinued in the U.S. Zaleplon is typically taken as a 10 mg dose right before bed to help you fall asleep, but it doesn't help you stay asleep. Butabarbital was known for its fast-acting properties but was not a first-choice treatment due to its potential for habit formation. Zaleplon can cause side effects like headache and dizziness, and it has a risk of dependence and withdrawal symptoms. Butabarbital also had a risk of addiction, which contributed to its discontinuation. While zaleplon is a Schedule IV controlled substance, butabarbital was classified as Schedule III, indicating a higher potential for misuse.
