How Does Quetiapine 400mg XR Work?

Quetiapine 400mg XR works by:

  • Regulating Neurotransmitters: Modulates dopamine and serotonin levels in the brain, helping to stabilize mood, thought processes, and emotional well-being.
  • Extended Release: Gradual and steady release of the active ingredient maintains consistent therapeutic levels, ensuring long-lasting symptom relief and improved daily functioning.

This mechanism offers comprehensive symptom control with fewer fluctuations in medication levels, enhancing treatment adherence and outcomes.

How to Use Quetiapine 400mg XR

  1. Dosage: Take Quetiapine 400mg XR exactly as prescribed by your doctor. Dosage is tailored to your specific condition and treatment response.
  2. Administration: Swallow the tablet whole with water. Do not crush, chew, or split the tablet, as this can interfere with the extended-release properties.
  3. Timing: Typically taken once daily, preferably in the evening, to minimize side effects like drowsiness during the day.
  4. Adherence: Do not skip doses or stop taking the medication abruptly without consulting your doctor, as this may lead to withdrawal symptoms or relapse.
