Product Overview

Q-Siz SR 400 is a sustained-release tablet medication containing the active ingredient Quetiapine. This formulation is designed to provide a controlled release of the medication over an extended period, offering convenient dosing for individuals with psychiatric disorders. Q-Siz SR 400 is commonly prescribed to manage conditions such as schizophrenia, bipolar disorder, and major depressive disorder.


Q-Siz SR 400 is primarily used for the treatment of psychiatric disorders, including schizophrenia, bipolar disorder, and major depressive disorder. It helps alleviate symptoms such as hallucinations, delusions, mood disturbances, and depressive episodes by acting on certain neurotransmitters in the brain.

How to Use

Q-Siz SR 400 tablets should be taken orally with water, preferably at the same time each day. It is important to swallow the tablet whole and not crush, chew, or break it, as this may affect the sustained-release mechanism. Follow the dosage instructions provided by your healthcare provider carefully to ensure optimal therapeutic benefit.

How it Works

Quetiapine, the active ingredient in Q-Siz SR 400, belongs to a class of medications known as atypical antipsychotics. It works by blocking the activity of certain neurotransmitters, including dopamine and serotonin, in the brain. This helps regulate abnormal brain activity associated with psychiatric disorders, leading to a reduction in symptoms such as hallucinations, delusions, and mood disturbances.

Dosage and Administration

The dosage of Q-Siz SR 400 may vary depending on the specific psychiatric disorder being treated and individual patient response. It is typically initiated at a low dose and gradually increased under the supervision of a healthcare provider. Dosage adjustments may be necessary based on the patient’s response and tolerance. The sustained-release formulation allows for once- or twice-daily dosing, providing continuous symptom relief.


Q-Siz SR 400 offers several benefits for individuals with psychiatric disorders, including:

  • Convenient once- or twice-daily dosing
  • Controlled release of medication for sustained symptom relief
  • Reduction in symptoms such as hallucinations, delusions, and mood disturbances
  • Improvement in overall quality of life
  • Management of both positive and negative symptoms of schizophrenia

Common Side Effects

Common side effects of Q-Siz SR 400 may include drowsiness, dizziness, dry mouth, constipation, and weight gain. These side effects are usually mild and transient, but if they persist or worsen, medical attention may be required.


Q-Siz SR 400 should be used with caution in elderly patients, as they may be more sensitive to its effects, especially dizziness and orthostatic hypotension. It may also increase the risk of suicidal thoughts and behaviors in children, adolescents, and young adults with psychiatric disorders. Q-Siz SR 400 may interact with certain medications, so it is essential to inform the healthcare provider about all current medications, supplements, and medical conditions before starting treatment.
