Abstract:
Caffeine can cause or worsen psychiatric symptoms but also has the potential to interact with many psychiatric medications. This article provides a literature review regarding interactions between caffeine and psychiatric medications. Caffeine is metabolized by the CYP1A2 enzyme and also acts as a competitive inhibitor of this enzyme. Thus, caffeine can interact with a wide range of psychiatric medications, including antidepressant agents, antipsychotic agents, antimanic agents, antianxiety agents, and sedative agents. These interactions may lead to caffeine-related or medication-related side effects that may complicate psychiatric treatment. By recognizing this potential, along with educating the patient, and utilizing a tapering approach, prevention of caffeine interactions is achievable.
