Does Trazodone Cause Heartburn?
Trazodone is not documented to cause heartburn as a side effect. Based on FDA labeling and available clinical evidence, heartburn is not listed among trazodone's adverse reactions.
Evidence from FDA Drug Labeling
The official FDA prescribing information for trazodone 11 lists extensive adverse reactions including:
Gastrointestinal effects:
- Nausea/vomiting (10-13%)
- Diarrhea (1-5%)
- Increased salivation
- Flatulence
Notably absent: Heartburn, acid reflux, or gastroesophageal symptoms are not mentioned anywhere in the comprehensive adverse reaction profile.
Clinical Context
Interestingly, trazodone has actually been studied as a treatment for esophageal symptoms. A controlled trial demonstrated that low-dose trazodone (100-150 mg/day) provided significant benefit for patients with esophageal contraction abnormalities and chest pain, with the treatment group showing 59% residual symptom distress versus 108% in placebo 2. This suggests trazodone may have neutral or even beneficial effects on esophageal symptoms rather than causing them.
Common Pitfalls
Do not confuse trazodone's gastrointestinal side effects with heartburn:
- Nausea and vomiting are the most common GI complaints (occurring in 10-13% of patients) 1
- These are distinct from heartburn/reflux symptoms
- If a patient reports "stomach upset," clarify whether they mean nausea versus burning retrosternal discomfort
Consider alternative explanations if a patient on trazodone reports heartburn:
- Concurrent medications (NSAIDs, aspirin, other drugs)
- Underlying gastroesophageal reflux disease
- Dietary factors
- Positional factors (lying down after dosing)
Bottom Line
Heartburn is not a recognized adverse effect of trazodone based on FDA labeling 11 and clinical trial data. If heartburn develops in a patient taking trazodone, investigate other causes rather than attributing it to the medication.
