There are 679 drugs known to interact with quetiapine, along with 23 disease interactions, and 6 alcohol/food interactions. Of the total drug interactions, 129 are major, 544 are moderate, and 6 are minor.
You should not use quetiapine if you are allergic to it. Quetiapine may increase the risk of death in older adults with dementia-related psychosis and is not approved for this use. Quetiapine is not approved for use by anyone younger than 10 years old.
Warnings: There may be a slightly increased risk of serious, possibly fatal side effects (such as stroke, heart failure, fast/irregular heartbeat, pneumonia) when this medication is used by older adults with dementia. This medication is not approved for the treatment of dementia-related behavior problems.
Quetiapine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
Seroquel use may also be directly implicated in memory issues for some patients. This likely has to do with the mechanism by which it works to affect dopamine regulation. The rewarding, accomplished feeling dopamine produces is believed to be central to learning and memorization.
The biggest disadvantages of Seroquel are the potential long-term side effects, which can include tardive dyskinesia, increased blood sugar, cataracts, and weight gain. For teens and young adults, the medication may also cause an increase in suicidal thoughts and behaviors.
Quetiapine is a medication that works in the brain to treat schizophrenia. It is also known as a second-generation antipsychotic (SGA) or atypical antipsychotic. Quetiapine rebalances dopamine and serotonin to improve thinking, mood, and behavior.
Quetiapine may cause drowsiness, trouble with thinking, trouble with controlling body movements, or trouble with your vision (especially during the first week of use), which may lead to falls, fractures, or other injuries.
Quetiapine (Seroquel) is used to improve mood, thoughts, and behaviors for people with schizophrenia and bipolar disorder. The extended-release form of quetiapine (Seroquel) can also be used to treat depression when combined with another antidepressant.
That being said, I would ask your doctor how long it should take for you to get drowsy. The patients I have who take this medication say that they are asleep within about 30 minutes, but they are often on other medications such as pain meds, etc.
Many people say that it takes four to six weeks for quetiapine to show its full effect. However, some people experience benefits sooner than this. You should stay in touch with your doctor to see how it goes over the first few weeks. They might do some tests to check your symptoms.
It's fine to take paracetamol, aspirin or ibuprofen with quetiapine, assuming these are appropriate for you. If you find quetiapine makes you drowsy or constipated, it's best to avoid taking co-codamol, because this painkiller could make these problems worse.
Seroquel is an antipsychotic that helps to calm and relieve psychotic thoughts. It is often given because it is quite sedating; however, care is needed because it also lowers blood pressure.
Interactions between your drugs
No interactions were found between Seroquel and Vitamin D3. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
If you take quetiapine for schizophrenia or depression, you may need to take it for a long time, maybe several years. If you take it for mania or depression in bipolar disorder, you may need to take it for a few weeks or months.
It is a long-term treatment for episodes of mania and depression, and it's usually prescribed for at least 6 months. Lithium is a mood stabiliser, which means it helps to keep your mood stable and control your symptoms of mania and depression. Quetiapine also helps symptoms of mania and depression.
Serious Side Effects
Some of these include: Increased risk of death due to dementia-related psychosis. Increased risk of suicidal thoughts.
Seroquel has been studied and is still being researched as a treatment option for generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD). Research shows that Seroquel can be particularly effective in treating generalized anxiety disorder.
SEROQUEL XR is indicated for use as adjunctive therapy to antidepressants for the treatment of MDD. The efficacy of SEROQUEL XR as adjunctive therapy to antidepressants in MDD was established in two 6-week trials in adults with MDD who had an inadequate response to antidepressant treatment [see Clinical Studies].
Do not stop taking SEROQUEL, or change the times of day you take SEROQUEL, without talking to your doctor first. If you stop taking SEROQUEL abruptly you may experience withdrawal symptoms such as insomnia (not being able to sleep), nausea, and vomiting.
It is the first drug in the modern era to be prescribed widely for sleep, anxiety, depression, and schizophrenia: it is either a miracle, or the most stupendous con-job ever perpetrated on patients, and the eternally gullible psychiatric fraternity.
The rate of self-harm was elevated in the year after quetiapine was first prescribed, compared to the unexposed period: IRR at 0–1 months 1.85 (95%CI 1.46–2.34), IRR at 1–2 months 1.96 (95% CI 1.55–2.48) and IRR at 2–3 months 1.54 (95% CI 1.19–1.98).
Absorption: Quetiapine fumarate is rapidly absorbed after oral administration, reaching peak plasma concentrations in 1.5 hours. The tablet formulation is 100% bioavailable relative to solution.
