Seroquel (Quetiapine) Buyer and Patient Handbook in Singapore
What is Seroquel?
Seroquel (Quetiapine) is an atypical antipsychotic tablet used primarily to treat Schizophrenia, Bipolar Disorder, and Major Depressive Disorder as an adjunct. It belongs to the dibenzothiazepine class and works by modulating dopamine and serotonin activity in the brain. In Singapore, Seroquel is approved by the Health Sciences Authority (HSA) and is available in 25 mg, 50 mg, 100 mg, 200 mg, and 300 mg tablets.
Who Should Use Seroquel?
- Adults diagnosed with schizophrenia or Schizoaffective Disorder
- Patients experiencing manic or depressive episodes of bipolar disorder
- Individuals with major depressive disorder who need augmentation therapy
- People whose symptoms are not adequately controlled by first-line mood stabilisers
How Does It Work?
Seroquel blocks dopamine-D2 receptors and serotonin-5HT2A receptors, reducing psychotic thoughts and stabilising mood. Think of it as a traffic controller that smooths the flow of neurotransmitter “vehicles,” preventing jams that cause hallucinations or extreme mood swings. It has a low potential for dependence, but abrupt discontinuation can cause rebound symptoms, so tapering is advised under medical supervision.
Why Choose Seroquel?
- Brand reliability: Seroquel is manufactured to strict quality standards, ensuring consistent tablet potency.
- Flexible dosing: The wide range of strengths allows clinicians to tailor the dose to the patient’s response and tolerance.
- Generic alternatives: Quetiapine is also sold as a generic tablet, offering a cost-effective option with the same therapeutic effect.
Off-label uses (e.g., Insomnia) should only be pursued after thorough discussion with a qualified healthcare professional.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- Schizophrenia: Start 25 mg twice daily; titrate to 300 mg twice daily as needed.
- Bipolar mania: 50 mg twice daily; increase to 400 mg twice daily.
- Bipolar Depression & augmentation: 50 mg once daily, may rise to 300 mg once daily.
How to Take
- Swallow tablets whole with a full glass of water.
- For doses >100 mg, taking with food can reduce dizziness.
- Do not crush, chew, or split extended-release tablets.
Missed Dose
- If you remember within 4 hours, take the missed tablet.
- If it’s later than 4 hours, skip it and resume your regular schedule-avoid doubling up.
Overdose
- Call emergency services (995) immediately.
- If possible, provide the amount taken and time of ingestion.
- Do not induce Vomiting unless instructed by a poison-information centre.
Special Populations
- Elderly: Start at half the usual dose; monitor for orthostatic hypotension.
- Renal impairment: No dosage adjustment needed for mild-moderate loss; severe impairment may require a 25 % reduction.
- Hepatic impairment: Reduce dose by 25 % for moderate liver disease.
- Women of child-bearing age: Discuss potential risks; Seroquel is classified as Pregnancy Category C in Singapore.
Lifestyle & Diet
- Avoid grapefruit juice, which can increase blood levels of quetiapine.
- Alcohol may amplify sedation; limit intake.
- Maintain a regular sleep-wake schedule to support mood stability.
Precautions and Warnings
- Monitor for signs of hyperglycaemia, especially in patients with Diabetes.
- Regularly check lipid profiles and weight, as Seroquel can cause metabolic changes.
- Beware of orthostatic hypotension; rise slowly from sitting or lying positions.
- Sudden discontinuation may trigger withdrawal symptoms such as insomnia, Nausea, or Anxiety.

Frequently Asked Questions
How long does it take for Seroquel to start working?
Most patients notice a reduction in anxiety or Agitation within 1-2 days, while full antipsychotic effect may require 2-4 weeks of consistent dosing.
Can I drink coffee while taking Seroquel?
Yes, moderate caffeine intake is safe, but excessive coffee may worsen insomnia if you are already sensitive to the sedative effect.
Is it safe to drive after my first dose?
Seroquel can cause drowsiness, especially at higher doses. Avoid driving or operating machinery until you know how the medication affects you.
What should I do if I gain weight while on Seroquel?
Discuss lifestyle modifications with a dietitian and consider regular exercise. Your clinician may also evaluate dose reduction or switching to another agent.
Can Seroquel be taken during pregnancy?
It is a Category C drug; use only if the potential benefit justifies the risk. Consult your obstetrician for individualized advice.
Will Seroquel interact with my antihypertensive medication?
No major interaction is expected, but Seroquel may cause orthostatic hypotension. Monitor blood pressure, especially after dose adjustments.
How should I store Seroquel if I travel abroad?
Carry the tablets in their original packaging, keep them at room temperature, and place them in a carry-on bag to avoid temperature extremes in luggage.
What is the recommended way to taper off Seroquel?
Gradually reduce the dose by 25 % every 1-2 weeks under medical guidance to minimise withdrawal symptoms.
Can elderly patients safely use Seroquel?
Yes, but start at a lower dose (e.g., 12.5 mg twice daily) and monitor for falls, dizziness, and metabolic changes.
Does Seroquel affect my blood test results?
It can elevate fasting glucose and lipid levels; periodic monitoring is advised.

Reviews
Been on 100mg of Quetiapine for Bipolar II for three months now. The sedating factor is a blessing. I actually sleep through the night, but man, the morning grogginess is brutal. Seriously feels like a lead blanket. My hack: I take it at 8 PM, not 10 PM, to give my system enough time to process before my 6 AM alarm. Huge appetite increase though. I'm fighting the fridge constantly.
Just started the 25mg dose for insomnia and anxiety. It knocks me out fast, which is great, but the dry mouth is insane. Like sandpaper tongue and I wake up chugging water. I also feel this weird restless legs sensation right before I drift off-it's called Akathisia, I think? Still debating if the deep sleep is worth this zombie feeling for the first two hours of my day.
Used to take 300mg Seroquel, lowered it to 200mg recently. It stabilized my intense mood swings from Borderline Personality Disorder, but the weight gain was a crushing side effect. I gained 15kg in the first year. Now I swear by taking it 30 mins *after* working out in the evening, focusing on protein intake before bed to mitigate the munchies. It's manageable, but requires constant vigilance.
This 50mg pill is the only thing that shuts up the constant noise in my head. I use it strictly as needed during high-stress periods, not daily. If I take it regularly, my blood sugar numbers spike, which is scary. My trick: if I need a fast effect (within 45 mins), I chew the 50mg pill a bit before swallowing it with water. It tastes terrible, but it hits harder and faster when panic starts.
Switched to Quetiapine 100mg after struggling with Zoloft. It's effective against psychosis symptoms, keeping the paranoia whispers quiet, but the physical sedation makes motivation zero. I feel perpetually lazy. Getting up to do daily tasks is hard. If you have to take this, you ABSOLUTELY need to schedule intense daytime activity, otherwise the couch becomes your spirit animal.
I’ve been taking 300mg ER (Extended Release) for years for major depressive episodes. The extended release version saves my life because the crash isn't as immediate or severe as the Immediate Release pills. However, the withdrawal if you miss even one dose is hell. Intense rebound insomnia and sometimes "brain zaps." Do not stop taking this abruptly, ever.
On 25mg Seroquel for sleep and 150mg Lamictal for mood. My sleep quality is fantastic for the first time in years. Mixed review though: I get terrible nasal congestion. It feels like I have a permanent cold every morning. My doctor said it's a known side-effect. Also, my memory is definitely fuzzier compared to before. I forget simple words during conversations sometimes.
Newbie here, just upped my dose from 25mg to 50mg Seroquel. I feel like I'm constantly walking in molasses. Everything takes effort. They say the fog clears, but when? I use it to manage anxiety attacks at night, and it works-the crushing anxiety stops-but I feel addicted to the sleep component now. If I stop, I worry I'll never rest again. It's a necessary evil.
