Quetiapine — often known by the brand Seroquel — is an atypical antipsychotic used for schizophrenia, bipolar disorder, and as an add-on for major depression. It’s also prescribed off-label for sleep or anxiety, but those uses carry extra risk. This page gives straightforward, usable information: what quetiapine does, common dose ranges, side effects to watch for, and simple safety tips.
Quetiapine works mainly by blocking certain dopamine and serotonin receptors, which helps reduce psychosis and mood swings. Typical adult dosing varies by condition: for schizophrenia doctors often aim between 150–800 mg/day; for bipolar mania 400–800 mg/day in divided doses; for depression as an adjunct 50–300 mg/day. There are immediate-release (IR) and extended-release (XR) forms — XR is usually taken once daily, often at night. Elderly people and those with liver problems usually start much lower and need careful follow-up.
Expect some common, usually manageable effects: sleepiness, dry mouth, constipation, dizziness, and weight gain. More serious issues include metabolic changes (higher blood sugar and cholesterol), low blood pressure when standing (orthostatic hypotension), and rare movement problems like tardive dyskinesia. Older adults with dementia have a higher risk of death on antipsychotics — that’s a firm safety warning.
Quetiapine is broken down by the liver enzyme CYP3A4. Medicines like ketoconazole, some antibiotics, or grapefruit can raise quetiapine levels; carbamazepine and some seizure drugs can lower them. Alcohol and other sedatives add to drowsiness. If you take heart drugs or other QT-prolonging meds, mention this to your prescriber — an ECG might be advised.
Simple monitoring helps catch problems early: check weight, fasting blood sugar, and lipids before starting and periodically after. Measure blood pressure and watch for signs of liver trouble (yellowing skin, dark urine). If you have heart issues or take interacting drugs, your doctor may order an ECG or adjust doses.
Practical tips: follow your prescriber's dose and don’t stop quetiapine suddenly — tapering avoids withdrawal and relapse. If it makes you sleepy, try taking it at bedtime. Don’t mix alcohol with quetiapine. If you miss one dose, follow the specific advice from your pharmacist or clinician — generally skip the missed dose if it’s almost time for the next one, and don’t double up.
Call your doctor or go to urgent care for severe symptoms: fainting, fast or irregular heartbeat, very high fever with stiff muscles and confusion (possible neuroleptic malignant syndrome), or new or worsening suicidal thoughts. For everyday questions — side effects, interactions with other meds, or how long effects take — your prescriber or pharmacist can give guidance tailored to you.
If you’re comparing treatments or wondering about buying meds online, read trusted reviews and always use licensed pharmacies. Quetiapine can help many people, but like any strong medicine it needs careful use and follow-up.
