What Experts Say

Seroquel Tablet 25mg is quetiapine fumarate at its lowest available strength. Psychiatrists prescribe it mainly as a starting or titration dose rather than a full treatment dose, since the standard target doses for schizophrenia and bipolar disorder are much higher.

At this low strength, quetiapine acts mostly through histamine H1 and alpha1 adrenergic receptor blockade, which explains its sedating effect. Its antipsychotic action through dopamine D2 and serotonin 5-HT2A receptor blockade becomes more prominent only as the dose is raised over several days.

Doctors across Pakistan often use this 25mg strength for the first two to four days of treatment before increasing the dose, and sometimes as a short term, low dose adjunct for disturbed sleep or anxiety when other options have not worked. Even at this dose, routine monitoring of blood pressure, weight, and blood sugar is still recommended.
