Compare Sonata vs. Hetlioz

Zaleplon (Sonata) and Hetlioz (tasimelteon) are both medications used to help with sleep, but they work in different ways and are used for different conditions. Zaleplon is a sedative-hypnotic that helps you fall asleep quickly by working on gamma-aminobutyric acid (GABA) receptors in your brain. It's used for short-term treatment of insomnia and is available as a lower-cost generic. However, it can be habit-forming and may cause dependence. On the other hand, Hetlioz is a melatonin receptor agonist that helps regulate your sleep cycle, especially if you are totally blind with non-24-hour sleep-wake disorder or have Smith-Magenis Syndrome. Hetlioz is not habit-forming but can take weeks to months to show effects. It's available in both brand and generic forms. While Zaleplon is taken right before bedtime, Hetlioz needs to be taken at the same time every night on an empty stomach. Both medications have specific side effects and interactions, so it's important to follow your healthcare provider's instructions carefully.
