Insomnia Medicines Explained: Types of Sleeping Tablets and How They Work
Millions of people struggle to fall asleep or stay asleep. If lifestyle changes have not been enough, a doctor may consider a sleeping tablet. But “sleeping pills” is not one category. Different medicines work in very different ways. This guide explains the main types of insomnia medicines, how they work, who they suit and what safety rules apply.
Main Types of Insomnia Medicines
1. Z-drugs (non-benzodiazepine hypnotics)
Z-drugs such as zopiclone and eszopiclone boost the calming brain chemical GABA, which slows brain activity and helps you fall asleep faster. They are for short-term use only. Browse Nappie 7.5 mg, Zopirise 7.5, Eszop 1 mg and Eszopira 2. For background read the comprehensive guide to zopiclone pills.
2. Orexin receptor antagonists
This newer class, which includes lemborexant, blocks orexin, the brain’s “stay awake” signal, rather than sedating the whole brain. They help with both falling asleep and staying asleep. See Dayvigo 5 mg and Dayvigo 10 mg. They are not suitable for people with narcolepsy.
3. Melatonin
Melatonin is the body’s own sleep-timing hormone. It works best for body-clock problems such as jet lag and shift work rather than severe insomnia. Learn more in our melatonin and zopiclone guide or see melatonin products.
4. Other medicines used for sleep
Some sedating antidepressants and antihistamines are used in specific situations, and older benzodiazepines are now used sparingly because of dependence risk. Your doctor will decide what suits you.
