###Human: Am I feeling lethargic due to Fluvoxamine? ###Assistant: Hello. Yes, you are right, Fluvoxamine has a side effect of increased sedation. Because of sedation person feels lethargy. You can do this thing that if Fluvoxamine is causing sedation, you can shift the medicine to night time, just before sleeping. This would sort out your problem. If this does not sort out your problem, you can have a trail of another SSRI Sertraline which is a safer option in the heart disease patients as you already tried Escitalopram and Paroxetine.
