Can I take trazodone with Lexapro (escitalopram)?
In many cases, doctors prescribe trazodone and Lexapro together. Both can be used safely when combined, but the combination is not risk-free and should be guided by a clinician because of additive effects on serotonin and sedation. Seek personalized advice from your prescriber or pharmacist, especially if you have other medications on board or any heart rhythm history.
What risks increase when trazodone is added to Lexapro?
The main concerns with the combination are:
Serotonin-related side effects (rare but important). Using two serotonergic medicines can raise the risk of serotonin syndrome, particularly if doses are increased quickly or additional serotonergic drugs are added. Symptoms can include agitation, confusion, sweating, fever, fast heart rate, tremor, and diarrhea.
Drowsiness and next-day impairment. Trazodone often causes sedation. Lexapro can also cause fatigue in some people. Together, they can make you more sleepy, affect driving, and increase fall risk.
Drug interactions that raise levels. Some medications slow the breakdown of escitalopram or trazodone, which can increase side effects. Your pharmacist can check your full medication list (including over-the-counter products and supplements).
QT rhythm concerns (heart electrical timing). Some antidepressants can affect QT interval in certain people, especially with other QT-prolonging drugs, low potassium/magnesium, dehydration, or existing heart rhythm issues. If you have known heart rhythm problems or you’ve had QT prolongation before, ask your clinician whether ECG monitoring is needed.
What signs mean you should get urgent help?
Get urgent care or emergency help if you develop signs consistent with serotonin syndrome (especially high fever with agitation/confusion, severe tremor, or worsening symptoms), fainting, severe palpitations, or chest pain.
If it’s mainly drowsiness, but it’s severe (can’t stay awake, near-falls, or you’re too impaired to function), contact your prescriber promptly for dose adjustment.
What’s the safer way to start if both are prescribed?
Follow the exact dosing plan your prescriber gives you. Ask whether you should:
- Start trazodone at the lowest dose (often at bedtime).
- Avoid alcohol and other sedatives.
- Be cautious with driving until you know how the combination affects you.
- Report new side effects quickly, especially after any dose changes.
When should you avoid the combination or ask specifically before taking it?
Before taking both, ask your prescriber/pharmacist if any of these apply:
- You take other serotonergic drugs (for example, some migraine medicines like triptans, tramadol, linezolid, MAO inhibitors, or certain supplements).
- You take other sedating medications (benzodiazepines, sleep medicines, opioids, antihistamines).
- You have a history of heart rhythm problems, fainting, or QT prolongation.
- You have significant liver disease (can affect drug levels).
- You’re pregnant, trying to become pregnant, or breastfeeding (risk/benefit decisions).
If you tell me your trazodone dose (mg), Lexapro dose (mg), and what you’re taking it for (sleep, anxiety, depression), I can help you think through the most likely safety considerations to discuss with your clinician.
