Quetiapine: Uses, Side Effects, and Drug Interactions

Brand names: Quetiapine

# Consumer Overview of Quetiapine Quetiapine is a prescription medication used to treat serious mental health conditions like schizophrenia, bipolar disorder, and depression. It works by helping to balance certain chemicals in the brain that affect mood and thinking. Doctors may prescribe this medicine when other treatments haven't worked well enough. It comes in tablet form and is typically taken by mouth one or more times per day, depending on what condition is being treated and how the patient responds to the medication. There are some important safety things to know about quetiapine. It can cause drowsiness, dizziness, and trouble concentrating, so it's not safe to drive or operate machinery until you know how it affects you. Some people may experience weight gain or develop problems with blood sugar levels, so your doctor will want to monitor you regularly. It's very important to tell your doctor about all other medications you're taking, as quetiapine can interact with many drugs—sometimes requiring your dose to be adjusted significantly. Never stop taking quetiapine suddenly without talking to your doctor first, as this can cause serious problems. If you're pregnant, nursing, or planning to become pregnant, discuss this with your doctor before starting this medication.
