Understanding Medications for Insomnia: What You Need to Know

Insomnia can leave you feeling exhausted, irritable, and unable to function at your best. While lifestyle changes and therapy are often the first steps in managing insomnia, some people may benefit from prescription medications to help them fall or stay asleep. In this post, we’ll break down the three most common categories of medications used for insomnia: benzodiazepines, “Z-drugs,” and orexin receptor antagonists.

🧠 1. Benzodiazepines

Examples: Temazepam (Restoril), Triazolam (Halcion), Estazolam

How they work: Benzodiazepines enhance the effect of GABA, a calming neurotransmitter in the brain. This helps reduce anxiety and promote sleep.

Pros:

• Work quickly (usually within 30 minutes)

• Helpful for short-term use during acute stress or travel-related insomnia

Cons:

• Can cause daytime drowsiness, dizziness, or memory issues

• Risk of tolerance, dependence, and withdrawal with long-term use

• Not recommended for people over 65 due to fall risk

Who might benefit: Individuals with short-term insomnia or co-occurring anxiety, under close medical supervision

🌙 2. Z-Drugs (Non-benzodiazepine hypnotics)

Examples: Zolpidem (Ambien), Eszopiclone (Lunesta), Zaleplon (Sonata)

How they work: Like benzodiazepines, Z-drugs also act on GABA receptors but are more selective, targeting areas of the brain related to sleep.

Pros:

• Generally fewer side effects than benzodiazepines

• Effective at helping people fall asleep (and in some cases, stay asleep)

Cons:

• Can still cause next-day drowsiness, especially with extended-release forms

• Risk of complex sleep behaviors (e.g., sleepwalking, sleep-driving)

• Potential for dependence or misuse with long-term use

Who might benefit: People with trouble falling asleep or waking during the night who haven't responded to lifestyle changes alone

🌘 3. Orexin Receptor Antagonists

Examples: Suvorexant (Belsomra), Lemborexant (Dayvigo), Daridorexant (Quviviq)

How they work: These medications block orexin, a brain chemical that helps keep you awake. By reducing orexin’s activity, they help you fall and stay asleep more naturally.

Pros:

• Low risk of dependence or withdrawal

• May improve both sleep onset and sleep maintenance

• Generally well-tolerated, even with longer-term use

Cons:

• Can cause drowsiness the next morning, especially in older adults

• May cause vivid dreams or nightmares

• Can be expensive and may not be covered by all insurance plans

Who might benefit: Adults struggling with chronic insomnia who prefer a non-habit-forming option

🛌 Final Thoughts:

Prescription sleep medications can be helpful tools—but they’re not a cure. Most work best when combined with cognitive behavioral therapy for insomnia (CBT-I), good sleep hygiene, and stress management. If you're struggling with sleep, talk to your healthcare provider. Together, you can create a plan that’s tailored to your needs and supports long-term rest and recovery.
