Compare Diflucan Tablet Strengths and Pack Sizes

Diflucan choices at a glance

Diflucan is a branded oral fluconazole tablet and an azole antifungal medicine. We offer it in five strengths: 50 mg, 100 mg, 150 mg, 200 mg and 400 mg. Each strength is available in several quantities, although the range is not identical across all strengths. The practical decision is therefore not simply which pack has the lowest unit price, but which available combination of strength and quantity matches the treatment a prescriber has advised.

Strength, number of tablets and total price need to be considered together. Two packs containing the same number of tablets are not interchangeable if their strengths differ, and a lower unit price does not make an unsuitable quantity better value. This guide explains how to compare the options we offer without turning a price comparison into an individual dosing recommendation.

How do the pack sizes compare in value?

Our current package comparison brings the relevant commercial details together. It shows the quantities and exact prices available from us, along with the resulting unit value and any relative saving identified within our offer. Use it to compare packs only after confirming the required strength and approximate number of tablets.

Unit value is useful when two available quantities would both reasonably cover the intended treatment. It is less useful when one pack would leave a substantial surplus or when treatment may change after clinical review. A larger pack can cost less per tablet, but that does not by itself make it the appropriate choice.

The available range also differs by strength. We offer 50 mg tablets in quantities from 60 to 360. For 100 mg, 150 mg, 200 mg and 400 mg tablets, our quantities run from 30 to 270. The comparison above provides the exact available combinations and current prices without requiring you to calculate the unit values separately.

Which strength and quantity fit the intended treatment?

Fluconazole dosing varies considerably according to the infection, its location and severity, kidney function, age and response to treatment. Some indications involve a single dose, while others require repeated doses over days, weeks or longer. This is why an offered pack should be matched to clear treatment instructions rather than selected on the assumption that a particular strength always represents a particular type of infection.

Before selecting an option, check the following points:

• Strength per tablet: confirm whether the instructions specify 50 mg, 100 mg, 150 mg, 200 mg or 400 mg. Do not substitute a different strength merely because its pack appears better value.
• Total quantity: work from the number of tablets required for the advised course, including any planned review point, rather than from the largest quantity available.
• Dosing schedule: establish whether the medicine is intended as a single dose, a daily course or an intermittent schedule. The same tablet count can cover very different periods.
• Likelihood of reassessment: longer treatment may require monitoring or adjustment. Buying well beyond a planned clinical review can lead to avoidable surplus.
• Storage and expiry: extra tablets provide no practical value if they cannot be used appropriately before their expiry date.

If the advised quantity does not exactly match one pack, compare the available combinations carefully. Choosing one or more packs that cover the required amount with limited surplus is usually more practical than defaulting to the largest option.

Diflucan and generic fluconazole

Fluconazole is the active ingredient, while Diflucan is a brand name. A generic fluconazole product with the same strength and dosage form contains the same active ingredient, but its manufacturer, appearance, inactive ingredients and packaging may differ. Those differences do not alter the identity of fluconazole, although an inactive ingredient may matter to someone with a particular allergy or intolerance.

This page concerns the Diflucan tablets we offer. Within this listing, the customer-facing choices are strength and quantity rather than a choice between several brands. If a prescription or treatment instruction names a specific brand, or if there is uncertainty about switching products, a pharmacist or prescriber can clarify whether a generic alternative is suitable.

Comparing a branded product with an external generic medicine also requires like-for-like information. Strength, dosage form, tablet count and active ingredient must all match before price differences are meaningful. A low total price for a smaller quantity or a different strength is not a direct comparison.

Established uses and product role

Fluconazole is used to treat susceptible fungal infections, particularly infections caused by Candida species. Its established uses include vaginal thrush, oral or oesophageal candidiasis, other Candida infections and cryptococcal meningitis. It may also be used to prevent fungal infections in selected people whose immune defences are significantly reduced.

The dose pattern differs between these uses. Uncomplicated vaginal thrush may be treated with a single 150 mg oral dose when oral treatment is appropriate, whereas oral thrush generally requires a repeated course rather than one tablet. Serious or invasive fungal infections involve different doses, longer treatment and closer clinical supervision. Prevention regimens are likewise determined by the person's risk and clinical circumstances.

These examples explain why the five offered strengths should not be treated as a simple progression from mild to severe illness. A higher-strength tablet is not automatically more effective for an individual, and several lower-strength tablets should not be combined to reproduce a higher dose unless that is specifically directed. The infecting organism, treatment site, kidney function, interacting medicines and intended duration all influence the decision.

How fluconazole works and practical use

Fluconazole belongs to the triazole group of azole antifungals. It inhibits a fungal enzyme involved in producing ergosterol, an important component of the fungal cell membrane. This disrupts membrane formation and limits the fungus's ability to grow. Whether fluconazole is suitable still depends on the organism and infection, as not all fungi are susceptible and resistance can occur.

Diflucan tablets are taken by mouth and can generally be taken with or without food. Swallow them with water and follow the supplied directions for dose, timing and duration. When a course has been prescribed, continue for the stated period unless a clinician advises otherwise; stopping early may allow an infection to persist or return.

If a dose is forgotten during a repeated course, it can generally be taken when remembered unless it is nearly time for the next dose. Two doses should not be taken together to compensate. The patient information leaflet and advice from a pharmacist or prescriber should take priority because the correct response can depend on the schedule.

Store the tablets at a controlled room temperature of 15°C to 30°C, in a tightly closed container and away from moisture. Keep them in their original packaging where possible, check the expiry date before use and keep all medicines out of the sight and reach of children. Unwanted or expired tablets should be taken to a pharmacy for safe disposal rather than put into household wastewater.

Safety and interaction considerations

Fluconazole can cause side effects and has clinically important interactions. Commonly reported effects include headache, stomach discomfort, diarrhoea, nausea and rash. Urgent medical advice is needed for signs of a severe allergic reaction, a serious skin reaction or liver problems, such as yellowing of the skin or eyes, unusually dark urine or persistent severe tiredness.

Pregnancy needs particular care. Fluconazole is generally avoided during pregnancy unless a clinician judges it necessary, especially at high doses or during prolonged treatment. Anyone who is pregnant, might be pregnant or is planning a pregnancy should obtain advice before taking it. Fluconazole passes into breast milk; a single 150 mg dose may be compatible with breastfeeding, but repeated or high-dose treatment requires individual assessment.

Important interaction and suitability points include:

• Fluconazole can increase the effect of some anticoagulants, including warfarin, which may raise the risk of bleeding and require monitoring.
• It can increase exposure to certain statins and raise the risk of muscle toxicity.
• Some sulfonylurea medicines used for diabetes may have a stronger effect, increasing the risk of low blood sugar.
• Medicines that affect heart rhythm, as well as other medicines processed by the liver, may interact significantly with fluconazole.
• Kidney impairment can require a dose adjustment for repeated treatment, while liver problems may call for additional caution or monitoring.
• Paediatric doses are based on factors such as body weight, age and indication and should not be estimated from an adult pack.

Dizziness and, rarely, seizures can affect driving or the use of machinery. Anyone affected should not drive or operate machinery until the symptoms have passed. A pharmacist or prescriber should be given a complete list of prescription medicines, non-prescription products and supplements before treatment begins.

What should you know about UK access and our ordering policy?

Diflucan is classified as a prescription-only medicine in the United Kingdom. That regulatory classification concerns how the medicine is legally supplied in the UK and is separate from the ordering requirements we apply on our website.

Under our product-specific ordering policy, we do not require a customer to upload or provide a prescription document for us to accept an order for this product. This checkout requirement does not change Diflucan's UK prescription-only classification, establish that a particular strength or quantity is clinically suitable, or replace advice from a qualified healthcare professional.

Because the strengths and offered quantities can support very different treatment patterns, customers should have clear instructions before choosing. If the intended dose, duration or reason for treatment is uncertain, the appropriate next step is to ask a prescriber or pharmacist rather than selecting an option from price information alone. Suspected side effects in the UK can be reported through the MHRA Yellow Card scheme.

Ordering and receiving your chosen pack

Once the appropriate strength and quantity are known, our comparison can be used to assess total price and unit value. A simple sequence helps reduce selection errors:

1. Confirm the product name, oral tablet form and fluconazole strength.
2. Confirm the total number of tablets required for the advised treatment or the period before clinical review.
3. Check which quantities we offer for that strength.
4. Compare the eligible options using the package-value information above.
5. Review the strength, quantity and order details again during our checkout before completing payment.

After checkout, we handle packing and dispatch according to the order details and the delivery information presented through our service. Customers should check the delivery details they provide, including the postcode, and review any available timing information before payment if treatment is time-sensitive.

Our support team is available 24 hours a day by email and online chat for questions about our listings or ordering process. A pharmacist is also available for medicine-related questions. Support can clarify the information presented on the page, but it cannot make an individual treatment decision without the clinical information needed for a proper assessment.

A balanced value decision

The most useful Diflucan option is the one that combines the correct strength with a suitable quantity at a reasonable total and unit cost. Price becomes meaningful only after medical suitability has narrowed the choice. Comparing packs in the opposite order can make an apparently economical option poor value if its strength is wrong or many tablets remain unused.

Start with the treatment instructions, then use our current package comparison to review the eligible quantities. Consider the total number of tablets, the point at which treatment will be reviewed, storage requirements and expiry rather than assuming that the largest pack is preferable. If two options would both appropriately cover the intended course, unit value can then help distinguish between them.

Our listing gives a broad choice across five Diflucan strengths, with different quantity ranges depending on strength. That flexibility supports several legitimate treatment patterns, but it does not make the options interchangeable. A careful match between strength, tablet count and intended use remains the soundest basis for choosing from the packs we offer.
