Seroquel (Quetiapine) Tablets: Prices, Strengths and Pack Sizes

We stock Seroquel, the original brand of immediate-release quetiapine tablets, taken by mouth. Our range covers five strengths - 25 mg, 50 mg, 100 mg, 200 mg and 300 mg - and a choice of pack sizes running from 10-tablet packs up to 360 tablets, depending on the strength selected. This guide walks through how our pack sizes, strengths and unit values compare, what each option is typically used for, and how ordering and delivery work for customers in the United Kingdom.

Seroquel (Quetiapine) Tablets: The Choices We Offer

Every Seroquel order starts with two decisions: the strength your prescriber has specified, and the pack size that matches how long you expect to need it for. Smaller packs may suit an initial supply or a period when a dose is being reviewed, while larger packs usually work out better value per tablet for an ongoing, stable regimen. Because quetiapine is normally taken daily over weeks or months rather than as a one-off course, getting the pack size right matters as much as getting the price right.

How Do Our Seroquel 300 mg Pack Sizes Compare on Price?

The clearest way to see how value changes with quantity is to look at the exact figures side by side. The comparison below sets out our current prices, the price per tablet, and the relative saving across the nine pack sizes we offer at the 300 mg strength.

The same general pattern holds across our other strengths: as the pack size grows, the price per tablet generally falls, so a larger pack can reduce your ongoing cost if you expect to take quetiapine for some time. That said, a lower unit price is only useful if the pack size actually matches your treatment plan - buying more tablets than you are likely to use before your prescriber next reviews your dose is not genuine value, however favourable the per-tablet figure looks.

Which Seroquel Strength and Quantity Should You Order?

Quetiapine is usually introduced at a low dose and adjusted by a prescriber over several days, so the strength you order should always follow current medical advice rather than price alone. A prescribed daily dose may require one tablet or a combination of tablet strengths. The table below shows how our pack-size choices vary by strength.

In short, our strength and pack options break down as follows:

• 25 mg - our lowest strength, available in packs from 30 to 360 tablets.
• 50 mg and 100 mg - flexible strengths available in both small and large packs.
• 200 mg - a higher tablet strength that may form part or all of a prescribed dose.
• 300 mg - our highest single-tablet strength, available in all nine listed pack sizes.

Whichever strength applies to you, choose a pack size that reflects the length of treatment agreed with your prescriber and how you store your medicine. Quetiapine tablets should be kept at 25°C, with excursions between 15°C and 30°C permitted, and used within their stated expiry. A very large pack bought for a short-term plan risks tablets sitting unused past review dates or storage limits, which offsets any saving on the unit price.

Seroquel Brand, Generic Quetiapine and Other Antipsychotic Options

Seroquel is the established brand name for quetiapine, and we list it here as an immediate-release tablet rather than the extended-release 'XL' formulation that some other quetiapine products use. Immediate-release dosing may be once or twice daily depending on the indication and prescribed schedule, while extended-release tablets are designed for once-daily dosing. The two forms are not interchangeable without a prescriber adjusting the dose and schedule, so it is worth confirming which form has actually been prescribed.

Some patients are prescribed a different atypical antipsychotic instead of, or alongside, quetiapine, such as Abilify (aripiprazole), which acts on similar receptor systems in a different way and carries its own dosing pattern and side-effect profile. Switching between antipsychotics is a clinical decision made with a prescriber based on response and tolerability, not a choice to make on price alone.

Established Uses of Seroquel (Quetiapine) Tablets

Quetiapine is an atypical antipsychotic established for treating schizophrenia and bipolar disorder in adults. Its roles in bipolar disorder include treating moderate to severe manic episodes, treating major depressive episodes associated with bipolar disorder, and helping to prevent recurrence in people whose manic or depressive episode responded to quetiapine. The strength and pack size you choose from our range should correspond to the indication, dose and schedule your prescriber has set out for you.

Clinical improvement is not necessarily immediate. Sedation can occur early, while improvement in mood, agitation or psychotic symptoms may develop over days to weeks. Continue treatment according to medical advice and seek a review if symptoms worsen, troublesome adverse effects occur, or the expected benefit does not develop.

Quetiapine Mechanism and Practical Tablet Use

Quetiapine works mainly by blocking dopamine and serotonin receptors in the brain, with additional effects on histamine and adrenergic receptors that contribute to its calming and sedating properties. This broad receptor activity helps explain both its antipsychotic and mood effects, and why sedation is often noticeable early in treatment, sometimes before the main therapeutic benefits on mood or psychotic symptoms become apparent.

Dosing generally starts low and is increased gradually over several days, following a titration schedule that differs by indication. Immediate-release tablets may be prescribed once or twice daily, depending on the reason for treatment and the dosing plan. They can usually be taken with or without food, though grapefruit juice should be avoided because it can raise quetiapine levels. A few practical points are worth keeping in mind:

• Take the tablets with water and follow the administration instructions supplied by your prescriber or pharmacist.
• Try to take each dose at a similar time every day to support a consistent routine.
• Do not stop quetiapine suddenly without medical advice, as abrupt withdrawal can cause symptoms including insomnia, nausea, headache, dizziness and irritability.
• Keep track of which strength you are currently taking, especially if your dose has recently changed.

Safety Considerations and Interactions to Discuss With Your Doctor

Quetiapine commonly causes somnolence, dizziness, dry mouth, constipation and weight gain. It has also been linked to raised blood glucose, changes in blood lipids, and new or worsening diabetes. Because it can cause sedation and affect alertness, avoid driving or operating machinery until you know how it affects you. Standing up slowly may help if you experience dizziness or a fall in blood pressure, particularly when treatment begins or the dose increases.

Quetiapine must not be used by anyone with known hypersensitivity to quetiapine or a tablet excipient. Concurrent use with strong CYP3A4 inhibitors, including certain azole antifungals, HIV protease inhibitors, macrolide antibiotics and nefazodone, is also contraindicated because these medicines can markedly increase quetiapine exposure. CYP3A4 inducers, including carbamazepine and phenytoin, can substantially lower quetiapine levels; starting or stopping one requires clinical review rather than an unsupervised dose change.

Other points to be aware of include:

• Somnolence and dizziness, particularly when starting treatment or increasing the dose.
• Dry mouth, constipation and gastrointestinal upset.
• Weight gain and changes in blood glucose and blood lipids over longer-term use.
• A need for caution with medicines that prolong the QT interval or otherwise affect heart rhythm.
• Urgent assessment for high fever with muscle rigidity, severe confusion, fainting, persistent involuntary movements, or signs of a severe allergic reaction.

Monitoring may include weight, blood glucose and blood lipids, together with blood pressure, movement-related adverse effects, symptom response and adherence. Additional checks may be appropriate for people with cardiovascular disease, diabetes risk factors, seizures, liver impairment or other relevant conditions. Older people with dementia-related psychosis require particular caution because antipsychotics are associated with increased risks in this group.

Pregnancy and breastfeeding both call for an individual discussion with a prescriber. Quetiapine is excreted into breast milk, and newborns exposed during the third trimester may need monitoring for withdrawal or extrapyramidal symptoms. Quetiapine is not recommended for children and adolescents under 18 years because the available evidence does not support routine use and some safety concerns are greater in younger patients. None of this replaces advice from the clinician managing your treatment, and any change in dose or strength should go through them rather than through a pack-size choice alone.
