What is Seroquel 25 mg?

Seroquel 25 mg (generic name: quetiapine) is the lowest standard dose of this atypical antipsychotic medication. Manufactured as film-coated tablets, it belongs to the second-generation antipsychotics class.

It works by balancing neurotransmitters in the brain, particularly dopamine and serotonin. While higher doses are used for major psychiatric conditions, the 25 mg dose is most commonly prescribed as a starting dose or for its strong sedative effects in off-label uses.

Key Uses of Seroquel 25 mg

Seroquel is FDA-approved for:

• Schizophrenia (usually at higher doses)
• Bipolar Disorder (manic and depressive episodes)
• Major Depressive Disorder (as an add-on to antidepressants)

Common Off-Label Uses of 25 mg:

• Severe insomnia and sleep disturbances
• Treatment-resistant anxiety
• Acute agitation or calming in psychiatric settings

The 25 mg strength is particularly favored for its potent sedative properties while keeping the overall medication load low.

Frequently Asked Questions (FAQ)
