Quetiapine, commonly sold under the brand name Seroquel, is a type of prescription medication called an antipsychotic drug. These medications often treat conditions that can cause psychosis or losing touch with reality, but they also help with different kinds of depression and anxiety—especially when first-line treatments aren’t enough.
There are two types of antipsychotic drugs. “Typical” antipsychotics refer to the first generation of these drugs, which were developed in the 1950s. “Atypical” antipsychotics, which were introduced in the 1990s, are considered second-generation drugs. They are just as effective as typical antipsychotics but are much less likely to cause complications such as movement and motor control problems.
Quetiapine is an atypical antipsychotic. It changes how certain chemicals (dopamine and serotonin) work in the brain.
Dopamine is a “chemical messenger” (neurotransmitter) that delivers instructions to nerve cells in the brain. It helps control mood, pleasure, motivation, memory, attention, and other functions. Serotonin is also a chemical messenger. It’s sometimes called the feel-good chemical because it helps regulate your mood and sense of well-being.
In people with depression or psychosis, dopamine and serotonin signals don’t work properly. Quetiapine works by blocking these abnormal signals.
Quetiapine (generic#1) worksThe most common side effects of Quetiapine are drowsiness, dizziness, dry mouth, constipation, weight gain, and increased blood pressure. Consult your doctor before using this medication if you have any of these serious side effects:
Most side effects go away within a few days. If you have any side effects, continue to take the prescribed dose and consult a doctor. Do not stop taking Quetiapine without first talking to your doctor.
This medication can be taken with or without food. Do not take this medication more often than once daily.
Dopamine and serotonin are dopamine and serotonin are serotonin hormones, which cause depressed mood and difficulty concentrating, making it difficult to worry, sleeping, or feeling sleepy or energized. Serotonin syndrome is a rare disorder in which the effects of a typical antipsychotic are life-threatening. The most common side effects of this medicine include:
Quetiapine also affects other chemicals (neurotransmitters). Neurotransmitters can vary based on how the brain uses them. For example:
First-generation antipsychotics and atypical antipsychotics may cause dangerous changes to your brain. Atypical antipsychotics, which are also called atypical antipsychotics, may work better for some people than typical antipsychotics. Atypical antipsychotics have blood-clotting effects that usually last around 4 to 6 hours.
Atypical antipsychotics can cause dangerous changes to the balance of neurotransmitters. Antipsychotics that block dopamine and serotonin can cause low white blood cell counts, nerve damage, and other problems.
The goal of treatment is to minimize the number of adverse effects, decrease the likelihood of relapse and to minimize the severity of adverse effects that can be observed during clinical trials. The objective is to obtain an adequate dose of the drug and to reduce the incidence of adverse effects in patients with bipolar I disorder, in whom the dose is insufficient. A typical dose schedule is 100 mg/day, which is given in two divided doses. A single dose of the drug can be given in a two-week period, with the maximum dose being 100 mg/day. If the patient experiences adverse reactions, the dose is increased to 100 mg/day. The total dose of the drug in the clinical trial is about 100 mg/day. If the patient experiences a recurrence of the depressive symptoms, the dose is decreased to 100 mg/day. The initial dosage of the drug is 50 mg/day. The dose should be titrated to a minimum of 100 mg/day by gradually decreasing the dose to 25 mg/day. The treatment should be continued for a minimum of 3 weeks. The total daily dose is about 100 mg/day. In the clinical trial, the average daily dose is about 50 mg/day. If the patient experiences a recurrence of the depressive symptoms, the dose is decreased to 50 mg/day.

The FDA has approved Seroquel for the following indications:
Seroquel is approved to help change the activity of chemicals in the brain, including serotonin, to help treat depression. Seroquel is a selective serotonin reuptake inhibitor (SSRI) that helps to increase the amount of serotonin available in the brain. If you are experiencing any of these symptoms, contact your healthcare provider immediately.

Seroquel can be given in either an oral tablet or an injection, but it is important to follow your healthcare provider's instructions carefully and not to give Seroquel without medical guidance.
Seroquel should be given with a full glass of water. Taking Seroquel with a full glass of water can increase the risk of side effects. The dose should be adjusted based on your body weight.
Your healthcare provider may recommend taking your dose at regular intervals to make sure the effects of Seroquel are not affecting your daily activities or overall well-being. To reduce the risk of side effects, your healthcare provider may recommend a low-dose combination therapy (LDBT).
Seroquel should not be given with food or alcohol. You may need to use a LDBT for the next few weeks. If you miss a dose, give it as soon as you remember if you remember and then skip the missed dose. Skip the missed dose if it is almost time for your next scheduled dose. Do not double the dose to catch up.
Seroquel can cause drowsiness. Avoid driving, operating machinery, or performing other dangerous tasks until you know how you react to it. Avoid excessive sedation (sedatives) and narcotic-like drugs.
If you are not sure how to stop taking Seroquel, it is important to contact your healthcare provider. You can gradually lower the dose of Seroquel you are currently taking.
