Struggling with sleepless nights? You’re not alone. Millions of people battle insomnia and disrupted sleep patterns. One medication often prescribed off-label to help with sleep is trazodone, originally developed as an antidepressant. Among the common dosages, 100mg trazodone stands out as a popular option for those looking to improve their sleep quality.
In this article, we’ll break down everything you need to know about taking 100mg trazodone for sleep, including how it works, what to expect, and important safety considerations.
What Is Trazodone?
Trazodone is a prescription medication primarily used to treat major depressive disorder (MDD). It belongs to a class of drugs known as serotonin antagonist and reuptake inhibitors (SARIs).
While its antidepressant effects take time to kick in, one of trazodone’s immediate side effects—drowsiness—makes it effective for treating insomnia, especially when other sleep aids aren’t an option.
Why 100mg Trazodone Is Used for Sleep
Off-Label Sleep Aid
Although trazodone isn’t officially FDA-approved as a sleep aid, doctors frequently prescribe it off-label for insomnia due to its sedative properties.
- 100mg is a moderate dose, commonly used when lower doses (like 25mg or 50mg) are not effective enough.
- It helps people fall asleep faster and stay asleep longer without the addiction risks associated with traditional sleep medications like benzodiazepines.
How It Works for Sleep
Trazodone increases levels of serotonin, a neurotransmitter that helps regulate mood and sleep. It also blocks histamine and alpha-adrenergic receptors, both of which contribute to its sedating effect.
Benefits of 100mg Trazodone for Sleep
Taking 100mg trazodone before bed may offer several benefits:
- ✅ Improved sleep onset – You fall asleep more quickly.
- ✅ Longer sleep duration – Stay asleep with fewer awakenings.
- ✅ Non-habit forming – Lower risk of dependency compared to other sleep aids.
- ✅ Dual-purpose – Helps treat both insomnia and depression if both are present.
What to Expect: Onset and Duration
How Long Does It Take to Work?
Most people begin to feel drowsy within 30 to 60 minutes of taking trazodone. That’s why it’s typically taken right before bedtime.
How Long Does It Last?
The sedative effect can last for 6–8 hours, making it ideal for overnight use. Some users report grogginess the next morning, especially when starting the medication.
Common Side Effects
Like all medications, trazodone has potential side effects. Common ones include:
- Drowsiness
- Dry mouth
- Dizziness
- Headache
- Nausea
Next-Morning Drowsiness
This is one of the most reported drawbacks of taking 100mg trazodone. It may take some time for your body to adjust. To minimize this:
- Start at a lower dose and work up if necessary.
- Avoid alcohol and other sedating substances.
- Take the medication at the same time each night.
Who Should Avoid 100mg Trazodone?
Trazodone is not suitable for everyone. You should avoid or use it cautiously if you:
- Have a history of heart problems (risk of arrhythmia).
- Are already taking other serotonergic drugs (risk of serotonin syndrome).
- Have low blood pressure, as trazodone can cause hypotension.
Always consult a healthcare provider before starting or adjusting your dosage.

FAQs About 100mg Trazodone for Sleep
