From the Guidelines
It is not recommended to take clonazepam and trazodone together without direct medical supervision due to the potential for increased side effects and adverse interactions. The combination of these medications can lead to enhanced sedative effects, increasing the risk of drowsiness, dizziness, confusion, and difficulty concentrating 1. This combination may be particularly hazardous when driving or operating machinery.
Key Considerations
- Both clonazepam, a benzodiazepine, and trazodone, an antidepressant with sedative properties, affect the central nervous system, potentially leading to additive effects that can be stronger than either medication alone.
- The work group advised against the use of benzodiazepines or trazodone for the treatment of chronic insomnia disorder due to the substantial outweighing of benefits by harms, including risks for dependency, diversion, falls, cognitive impairment, and neuromuscular diseases 1.
- A systematic review found no significant differences in sleep efficiency or rate of discontinuation due to adverse events between trazodone and placebo in patients with chronic insomnia, although trazodone improved subjective sleep quality 1.
Recommendations for Use
- If prescribed both medications, it is crucial to follow the healthcare provider's instructions carefully and attend all scheduled follow-up appointments to monitor for potential adverse effects.
- Patients should be counseled on the potential risks associated with the combination of these medications, including the risk for serious injuries caused by sleep behaviors such as sleepwalking or sleep driving 1.
- To minimize adverse events, any prescribed nonbenzodiazepine BZRA should be administered at the lowest effective dose and for the shortest possible duration 1.
Conclusion is not allowed, so the answer ends here.
From the Research
Potential Interactions between Clonazepam and Trazodone
- There is limited direct evidence on the interaction between clonazepam (Klonopin) and trazodone (Desyrel) 2, 3, 4, 5, 6.
- However, it is known that both medications can cause sedation and may exacerbate each other's effects, potentially leading to increased risk of adverse reactions such as hypotension, bradycardia, and sedation 3.
- A study reported a possible clonidine-trazodone-dextroamphetamine interaction in a 12-year-old boy, which may suggest that trazodone can interact with other medications, including those with sedative properties like clonazepam 3.
- Trazodone has been used as a hypnotic for psychotropic-induced or other insomnias with some success, and its efficacy as a hypnotic in depressed subjects has been supported by clinical studies 4, 5.
- Clonazepam is a benzodiazepine used for the treatment of seizures and panic disorders, and its interaction with other medications, including oxycodone, has been reported to be potentially fatal 6.
- Given the potential for increased sedation and other adverse effects, caution is advised when considering concurrent use of clonazepam and trazodone, and patients should be closely monitored for signs of adverse reactions 3, 4, 5.
Key Considerations
- Patients taking clonazepam and trazodone concurrently should be monitored for increased sedation, hypotension, and bradycardia 3.
- The doses of both agents should be changed slowly, and blood pressure and pulse should be carefully monitored at baseline and then periodically during treatment 3.
- Administration of trazodone on an empty stomach, and especially dose increases on an empty stomach, should be avoided 3.
- Clinicians should be aware of the potential for increased risk of adverse reactions and adjust treatment accordingly 3, 4, 5.
