What does “DailyMed quetiapine fumarate tablet 400 mg, immediate-release” mean?
DailyMed is the National Library of Medicine’s public database of FDA label information for drugs. “Quetiapine fumarate tablet 400 mg, immediate-release” refers to the FDA-labeled product instructions for an immediate-release oral tablet strength of 400 mg, using quetiapine fumarate as the active ingredient. (DailyMed entries typically include the prescribing information, indications, dosing, and safety information.)
How is immediate-release quetiapine typically dosed at the 400 mg tablet strength?
DailyMed labeling for quetiapine immediate-release contains specific dosing schedules that depend on the indication (for example, schizophrenia or bipolar disorder) and the patient’s condition. The label also includes titration (gradual dose increases) and maximum dosing guidance. To give you the exact DailyMed dosing text for the 400 mg immediate-release tablet, the precise DailyMed product entry (manufacturer/labeler) is needed.
Where to find the exact DailyMed page for the 400 mg immediate-release tablet
To pull the correct prescribing information, search DailyMed for:
- Active ingredient: quetiapine fumarate
- Dosage form: tablet
- Strength: 400 mg
- Release type: immediate release
If you share the manufacturer/labeler name shown on the bottle (or a link to the specific DailyMed page), I can summarize the exact labeled dosing directions, warnings, and key patient instructions from that specific “400 mg immediate-release” entry.
What common safety warnings apply to quetiapine (Immediate-release)?
DailyMed quetiapine labeling generally includes boxed and non-boxed warnings and key precautions such as:
- Risk of suicidal thoughts/behavior in some patients at younger ages
- Orthostatic hypotension (dizziness/fainting on standing) and falls risk
- Metabolic changes (weight gain, blood sugar/lipids)
- Tardive dyskinesia risk
- Sedation/somnolence and driving impairment warnings
The exact wording and applicable populations depend on the label’s indication and age group.
Are there different “quetiapine 400 mg” products (IR vs XR) that get confused?
Yes. Quetiapine also exists as extended-release (XR) formulations. An “immediate-release” 400 mg tablet is not the same as an “extended-release” tablet, and the dosing schedules differ. Using the wrong formulation can lead to incorrect exposure and different side effects.
What if you want “how to take it” or “what to ask your prescriber”?
If you tell me the indication (schizophrenia vs bipolar disorder, for example), your age, and whether the prescription is for immediate-release or extended-release, I can help interpret what the DailyMed label is trying to achieve (titration vs maintenance dosing, timing with food, missed-dose guidance) for the 400 mg immediate-release form—using the exact label wording once you provide the specific DailyMed entry or manufacturer.
