Ambien vs. Silenor
See how Ambien and Silenor compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Ambien is a fast-acting controlled substance best suited for trouble falling asleep, while Silenor is a non-controlled option approved for staying asleep through the night.
Ambien carries risks of complex sleep behaviors and dependence, while Silenor's antihistamine mechanism has shown no known abuse potential in studies.
Generic Ambien is far less expensive than brand-only Silenor, though cost shouldn't be the only factor when choosing between them.
Ambien vs. Silenor Drug Summary
Ambien
Ambien is a non-benzodiazepine sedative-hypnotic that acts on GABA-A receptors and is approved for short-term insomnia in people who have trouble falling asleep. It's taken as a single 5 mg or 10 mg tablet at bedtime, ideally on an empty stomach.
Silenor
Silenor is a tricyclic antidepressant used at very low doses as a selective antihistamine sleep aid, approved for insomnia in people who struggle to stay asleep. It's taken once daily as a 3 mg or 6 mg tablet, doses far below those used to treat depression.

Ambien vs. Silenor Indications
Ambien
Ambien is FDA-approved for short-term insomnia, specifically for people who have trouble falling asleep. It's a Schedule IV controlled substance meant for brief use, not for nightly long-term reliance.
Difficulty falling asleep
Short-term treatment only
Not approved for chronic nightly use
Starting dose differs by sex (women start lower)
Silenor
Silenor is FDA-approved for insomnia in people who wake during the night and have trouble staying asleep. It's sometimes used off-label at much higher doses for depression or anxiety, though that's separate from its approved sleep use.
Difficulty staying asleep
Not approved for pediatric insomnia
Not approved for obstructive sleep apnea
Off-label use for depression/anxiety at higher doses
Ambien vs. Silenor Pros and Cons
Ambien
Ambien works quickly to help people fall asleep, but it carries real risks: complex sleep behaviors, next-day grogginess, and dependence potential as a Schedule IV drug. Generic zolpidem remains one of the least expensive sleep aids available.
Pros
Works quickly to help you fall asleep
Generic zolpidem costs roughly $15 to $90 per month without insurance, far less than brand Silenor
Dose can be tailored by sex and liver function
Decades of real-world use since approval in 1992
Cons
Risk of complex sleep behaviors like sleepwalking or sleep-driving
Schedule IV controlled substance with dependence potential
Next-day impairment risk, especially at 10 mg
Not approved for long-term nightly use
Silenor
Silenor targets sleep maintenance rather than sleep onset, and its antihistamine mechanism carries no known abuse potential. It's only available as the brand-name product, making it much pricier than generic Ambien, and it isn't recommended for people with certain heart, eye, or urinary conditions.
Pros
Not a controlled substance, no known abuse potential
Approved specifically for staying asleep through the night
Lower reported rates of dizziness and headache in trials
No next-day driving impairment warning on the label
Cons
Only available as brand-name, roughly $500 to $650 per month without insurance, much costlier than generic Ambien
Contraindicated with MAOIs, narrow-angle glaucoma, or severe urinary retention
Not recommended for people with severe sleep apnea
Fewer decades of real-world use since approval in 2010
