Key points
- Listed among the most severe overdose reactions
- Risk rises sharply with other CNS depressants
- Call 911 for any suspected overdose or serious breathing trouble
Respiratory arrest — a complete stop in breathing — is listed in trazodone's prescribing information among the most severe reactions reported in overdose. This risk rises sharply when trazodone is combined with alcohol, opioids, benzodiazepines, or other substances that also suppress breathing and the central nervous system.
Call 911 immediately for any suspected overdose or serious breathing difficulty, and contact Poison Control at 1-800-222-1222 for guidance.
Call your prescriber or seek care if you notice:
- Slow, shallow, or stopped breathing
- Unresponsiveness combined with slowed breathing
