Belsomra is a prescription medication designed to help adults with insomnia who struggle with falling asleep, staying asleep, or both. Its active ingredient, suvorexant, works differently from traditional sleeping pills by targeting brain pathways that regulate wakefulness rather than by sedating the nervous system directly.
In this clear and SEO-friendly guide, you’ll learn what Belsomra is, how it works, its uses, dosage, side effects, precautions, and answers to common questions that patients frequently search for online.

What Is Belsomra?
Belsomra (generic name: suvorexant) belongs to a newer class of medications called orexin receptor antagonists. Unlike older sleep medicines such as benzodiazepines (e.g., temazepam) or “Z-drugs” (e.g., zolpidem), Belsomra works by blocking orexin, a neurotransmitter responsible for wakefulness.
Belsomra comes in several tablet strengths:
- Belsomra 5 mg (rarely prescribed, mainly for dose adjustments)
- Belsomra 10 mg
- Belsomra 15 mg
- Belsomra 20 mg
- Belsomra 40 mg (maximum approved dose in some regions)
It is not available over the counter and requires a doctor’s prescription.
How Does Belsomra Work?
Belsomra targets the orexin system in the brain:
- Orexin is a neurochemical that helps you stay awake and alert.
- In insomnia, orexin activity may be overactive, preventing natural sleep onset.
- By blocking orexin receptors (OX1R and OX2R), Belsomra reduces wake signals, allowing sleep to occur more naturally.
This unique mechanism means:
- It is not sedating like traditional sleep drugs.
- It mimics the brain’s natural sleep–wake cycle.
- It carries a lower risk of dependence compared to older hypnotics.
Common Uses of Belsomra
Doctors may prescribe Belsomra for:
- Difficulty falling asleep (sleep onset insomnia)
- Difficulty staying asleep (sleep maintenance insomnia)
- Mixed insomnia – both falling and staying asleep issues
- Chronic insomnia when lifestyle changes alone are not effective
Note: Belsomra is not used for anxiety, depression, or short-term jet lag.
