Trazodone is a commonly prescribed medication for depression, insomnia, and sometimes anxiety. If you’re considering or currently taking 100mg of trazodone, it’s natural to wonder about its safety, especially with long-term use or in combination with other medications.
In this article, we’ll explore whether 100mg of trazodone is safe, how it works, its potential side effects, and what you should discuss with your doctor before taking it.
What Is Trazodone?
Trazodone is an antidepressant in a class of medications called serotonin modulators. It works by increasing serotonin levels in the brain, a chemical that helps regulate mood, sleep, and emotions.
Common Uses of Trazodone
Trazodone is prescribed for:
- Major depressive disorder (MDD)
- Chronic insomnia
- Anxiety disorders
- PTSD
- Off-label for fibromyalgia or chronic pain
Because it has sedating effects, many doctors prescribe it at lower doses (often 50mg–100mg) for sleep disorders rather than depression.
Is 100mg of Trazodone a Typical Dose?
Yes, 100mg is considered a common starting dose for many conditions, especially insomnia or mild depression.
Dosing Overview
- Sleep issues: 25mg to 100mg, typically taken before bed
- Depression: Usually starts at 150mg/day in divided doses, may increase gradually
- Maximum dose: Up to 400mg per day (600mg for inpatients), under supervision
100mg sits comfortably in the low to moderate dose range and is widely considered safe for many individuals when taken as prescribed.
How Safe Is 100mg of Trazodone?
When taken correctly, 100mg of trazodone is generally safe for most adults. However, individual safety depends on various factors:
Factors Affecting Safety
- Age and weight
- Liver or kidney health
- Other medications or supplements
- Alcohol use
- Underlying medical conditions
Always consult your doctor before starting or adjusting any medication, including trazodone.
Possible Side Effects of 100mg Trazodone
While trazodone is usually well-tolerated, it can cause side effects, especially when your body is adjusting to the dose.
Common Side Effects
- Drowsiness or dizziness

These symptoms often decrease over time as your body adapts.
Serious (But Rare) Side Effects

If you experience any of these, seek medical attention right away.
Trazodone Safety Tips: Best Practices at 100mg
To stay safe while taking 100mg of trazodone, follow these tips:
- Take it exactly as prescribed
- Avoid alcohol and recreational drugs
- Don’t mix with other sedatives without medical advice
- Inform your doctor of all current medications
- Take it at night to avoid daytime drowsiness
Also, never stop trazodone cold turkey—suddenly discontinuing can lead to withdrawal symptoms like anxiety, irritability, and sleep disturbances.
Who Should Be Cautious With Trazodone?
While trazodone is safe for many, it may not be suitable for everyone.
Talk to Your Doctor If You:
- Have a history of heart conditions
- Are currently taking MAO inhibitors

Your doctor might recommend a lower starting dose or suggest an alternative medication.
Trazodone Interactions to Watch Out For

- MAO inhibitors – should never be combined
- Blood thinners – risk of bleeding
- Antifungals and antibiotics – may affect trazodone metabolism
- Alcohol and benzodiazepines – increased sedation
Always disclose all prescriptions, OTC medications, and supplements to your healthcare provider.
Can You Overdose on 100mg of Trazodone?
An overdose on 100mg is unlikely in healthy adults, but doubling or tripling the dose, especially when combined with other depressants, can be dangerous.
Signs of Overdose:
- Extreme drowsiness
- Vomiting
- Seizures
- Irregular heartbeat
- Loss of consciousness
If you suspect an overdose, call 911 or poison control immediately.
