You should never stop these medications abruptly. Suddenly discontinuing escitalopram, quetiapine, and your migraine preventive can cause uncomfortable withdrawal symptoms, such as dizziness, anxiety, irritability, or headaches, and may cause your depression and migraines to return. To stop them safely, you must gradually taper the doses over several weeks. This slow reduction allows your brain and body to adjust safely. Please consult your prescribing doctor before making any changes. They will evaluate your progress and design a personalised, step-by-step tapering schedule to ensure you discontinue the medications safely and comfortably.
