Paroxetine has a relatively short half-life and is associated with a higher risk of discontinuation syndrome (also known as antidepressant withdrawal syndrome) upon abrupt cessation or rapid tapering. Symptoms can include dizziness, nausea, headache, paresthesias (electric shock sensations), anxiety, irritability, and flu-like symptoms. To minimize these symptoms, it is crucial to taper the medication slowly and gradually over several weeks to months, depending on the dose and duration of treatment. Abrupt cessation or rapid tapering (e.g., 5 mg every 2-3 days) is likely to induce significant withdrawal symptoms. Switching to another antidepressant is not indicated if the goal is complete discontinuation, and it would only delay the tapering process.
