To help reduce your side effects, you can discuss these alternatives with your doctor: For Olanzapine (linked to fatigue and constipation): Ask about switching to aripiprazole, which is generally less sedating and has fewer digestive side effects. For Clonazepam (high doses can cause severe fatigue): Discuss a gradual, supervised dose reduction or switching to buspirone for anxiety. For Escitalopram: Switching to another SSRI like sertraline or fluoxetine might better manage OCD with fewer appetite issues. For Levothyroxine: Request a blood test to check your thyroid levels. Incorrect dosing can directly cause tremors, fatigue, and constipation.\n\nNever change your medication regimen without your doctor?s guidance.
