FAQ
Store the tablets at room temperature between 20°C and 25°C in a tightly closed container. Protect them from moisture, heat and light, and keep them out of the reach of children.
Fildena is not identified as a UK-authorised medicine in the MHRA Products database. Its listed strengths should not be assumed to be UK marketing-authorisation strengths; the MHRA database can be used to check the status of a specific product.
A different appearance alone does not prove that the medicine is incorrect. Compare the active ingredient, strength, dosage form, manufacturer, package label, batch number, expiry date and any tablet imprint; do not take the tablets if the ingredient, strength, dosage form, seal or physical condition appears wrong or compromised.
Sildenafil is principally used to treat erectile dysfunction in adult men. Sildenafil is also used in different formulations and dosing regimens for pulmonary arterial hypertension, which requires specialist medical management.
Description
Fildena delivers oral sildenafil, the PDE5-inhibiting active ingredient behind the original Viagra tablet, across five strengths from 25 mg up to 200 mg. Because sildenafil only amplifies the erectile response to sexual stimulation rather than triggering arousal on its own, the practical decision for most UK buyers researching Fildena is less about whether it works and more about which strength, timing and pack size fits an individual routine. Comparing sildenafil against the longer-acting tadalafil in Cialis and the similar-duration vardenafil in Levitra before you buy Fildena online helps match onset time and duration to how your evenings actually look, rather than choosing a brand purely because it is the most recognised name on the shelf.
Fildena compared with Cialis and Levitra: which PDE5 option suits you
Sildenafil, tadalafil and vardenafil are all PDE5 inhibitors, meaning they work in the same way: by blocking the enzyme that breaks down cGMP in penile tissue, they let increased blood flow persist once sexual stimulation begins. Fildena's sildenafil typically starts working within 30 to 60 minutes of a dose taken on an empty stomach, with effects lasting around four to six hours, which suits planning around a specific evening rather than an entire weekend.

Key therapeutic similarities and differences between sildenafil and tadalafil for erectile dysfunction.
Tadalafil, sold as Cialis, has a much longer half-life, giving an effect that can last up to 36 hours and making it a common choice for couples who prefer not to time sex around a tablet. That flexibility comes with a trade-off: precise timing matters less, but tadalafil also stays in the system longer if a side effect or interaction becomes a problem.

Direct comparison of sildenafil and vardenafil options for managing erectile dysfunction.
Vardenafil, sold as Levitra, sits close to sildenafil in onset and duration but is dosed in smaller milligram amounts; differences in enzyme selectivity and individual response can also affect tolerability. Fildena's sildenafil remains one of the most extensively studied PDE5 inhibitors worldwide, with a long real-world safety record, which is part of why many UK buyers compare other options against it first.
What sets Fildena's tablet range apart
Where the branded originator is limited to three strengths, Fildena is available in our range as 25 mg, 50 mg, 100 mg, 150 mg and 200 mg tablets, giving a wider strength ladder than most sildenafil products on general sale. That range matters practically: a first-time user commonly starts at 50 mg and adjusts, while someone who has already established that 100 mg suits them elsewhere does not need to experiment with an unfamiliar brand's starting dose.
Fildena tablets are manufactured by Fortune Healthcare Pvt. Ltd., one of several manufacturers whose sildenafil-based tablets sit alongside Pfizer's originator Viagra and other generic producers such as Apotex, Sandoz, ratiopharm and Biogaran. The active ingredient and mechanism are identical across these; what differs between brands is tablet formulation, strength ladder and, in our catalogue, the pack sizes on offer.
How sildenafil works, and what that means for timing
Sildenafil inhibits the PDE5 enzyme in the smooth muscle of penile blood vessels, prolonging the effect of nitric oxide released during sexual stimulation and allowing the increased blood flow needed for an erection. It does not create desire or automatic arousal - sexual stimulation still has to happen for a Fildena tablet to have any visible effect. Onset is generally 30 to 60 minutes after swallowing the tablet whole with water, though a heavy or high-fat meal can measurably delay absorption, so taking Fildena on an empty stomach, or after a light meal, tends to give the fastest and most predictable result. The effect window of roughly four to six hours makes on-demand dosing, with no more than one dose in 24 hours, the normal pattern for sildenafil-based tablets such as Fildena; tadalafil may instead be used on demand or in a lower-dose daily regimen.
Fildena strengths, pack sizes and value across our range
We list Fildena in packs from as few as ten tablets up to 360 tablets for the 25 mg, 50 mg, 100 mg and 150 mg strengths, and from 60 up to 500 tablets for the 200 mg strength, so a first UK order and a long-term repeat supply can both be sized appropriately. As a general rule across our sildenafil pack sizes, the price per tablet falls as the pack size increases, which matters most to anyone who has already confirmed their preferred Fildena strength and simply wants to avoid reordering every few weeks.
The overview above sets out our current 50 mg Fildena pricing in pounds sterling across six pack sizes, letting you weigh a smaller trial pack against the better unit value of a larger one before you buy Fildena online. We update these prices directly in our checkout, so the figures shown there at the point of order remain the definitive ones.
Fildena's status in the United Kingdom and how we handle orders
In the United Kingdom, sildenafil products may be prescription-only medicines, while certain authorised 50 mg products can be supplied as pharmacy medicines to adult men who meet set criteria after a pharmacist's assessment. Fildena itself is not identified as an MHRA-authorised product, and its 150 mg and 200 mg tablets are not UK-authorised sildenafil strengths; an unlicensed medicine may only be supplied where the applicable legal and clinical requirements are met. For our own ordering process, we do not require you to upload or fax a prescription before we accept a Fildena order.
Our pharmacist-supported team is reachable by email or online chat 24 hours a day if you would like to check suitability first. Our ordering requirement does not change how sildenafil is classified more broadly in the UK, and if you are ever unsure, NHS medicine information and MHRA guidance remain useful reference points. If you would rather compare other recognised treatments first, our Erectile Dysfunction range covers further sildenafil, tadalafil and vardenafil options.
Taking Fildena correctly: dose, food and timing
Most adult men new to sildenafil are advised to start with a moderate dose, commonly 50 mg, taken roughly an hour before anticipated sexual activity, then adjust up towards 100 mg or down towards 25 mg based on effect and tolerability, always leaving at least 24 hours between tablets. Because Fildena's higher 150 mg and 200 mg tablets sit above the licensed sildenafil dose range used for erectile dysfunction in the UK, anyone considering them should treat that as a decision to discuss with a doctor or pharmacist rather than a simple step up the usual ladder. A light meal beforehand rarely causes problems, but a large, fatty meal can slow absorption and blunt the peak effect, and more than modest alcohol intake alongside sildenafil increases the chance of dizziness and a drop in blood pressure.
Interactions and safety checks before you take Fildena
Sildenafil's interaction profile is well documented, and the most serious risk by far involves nitrate medicines. Before starting Fildena, it is worth checking for the following:
Nitrates and nitric oxide donors - glyceryl trinitrate, isosorbide mononitrate or dinitrate, and recreational amyl nitrite ("poppers") combined with sildenafil can cause a dangerous, sometimes severe drop in blood pressure and must be avoided.
Alpha-blockers - medicines such as doxazosin or tamsulosin, often prescribed for blood pressure or an enlarged prostate, can compound sildenafil's blood-pressure-lowering effect and may require dose adjustment or medical supervision.
Other PDE5 inhibitors - tadalafil, vardenafil or avanafil should never be combined with Fildena; taking more than one PDE5 inhibitor at a time does not add benefit and increases the risk of side effects.
Grapefruit juice and strong CYP3A4 inhibitors - certain antifungals, some HIV medicines and grapefruit juice can raise sildenafil levels in the blood and may call for a lower starting dose.
Common side effects reported with sildenafil include headache, facial flushing, nasal congestion, indigestion, and a temporary blue-tinged or blurred change in vision; these are generally mild and settle as the tablet clears the body. Anyone experiencing an erection lasting longer than four hours, sudden vision or hearing loss, or chest pain during sexual activity should seek urgent medical attention rather than waiting for the tablet to wear off.
Who should avoid Fildena or seek medical advice first
Because sildenafil's main effect is on blood vessels, its contraindications and cautions are mostly cardiovascular. Fildena is not suitable, or needs a doctor's input first, for people who fall into any of these groups:
Anyone currently taking nitrate medicines for angina or using nitric oxide donors recreationally.
Anyone who has had a heart attack, stroke, or a life-threatening heart rhythm problem in the preceding six months, or who has unstable or severe uncontrolled heart disease.
Anyone with severely low or high blood pressure, severe liver impairment, or a history of non-arteritic anterior ischaemic optic neuropathy affecting one eye.
Women and anyone under 18, since Fildena's erectile-dysfunction strengths are formulated and dosed for adult men only.
Pregnant women should not use Fildena, since it has no established role in pregnancy and higher-dose sildenafil use in a fetal-growth-restriction trial was stopped early over safety concerns. UK guidance suggests breastfeeding, well-controlled diabetes and an unrelated allergy history are not automatic barriers to sildenafil use, but each is worth a quick conversation with a pharmacist if there is any doubt, particularly given sildenafil's mild tendency to cause dizziness or short-term visual changes that can affect driving or operating machinery.

Ordering Fildena online through us follows the same checkout as any other item: choose your strength and pack size, pay by Visa, Mastercard, American Express or JCB card, or settle by Bitcoin or USDT if you prefer crypto payment, and our support team stays reachable by email or online chat around the clock if a question comes up before you complete an order.
We have operated this catalogue since 2018, and our approach to an unlicensed-medicine listing like Fildena is to be transparent about its UK status rather than presenting it as an MHRA-authorised medicine, while still making it straightforward for UK customers who have decided sildenafil suits them to order Fildena online at a clear, checkout-confirmed price.
Delivery across the UK: what to expect when you order
Delivery experience in the UK varies with geography: a parcel bound for central London or Coventry generally moves through the postal network faster than one heading to a rural address, a Scottish island, or Northern Ireland, so we build a realistic range into both delivery options rather than promising a single fixed day.

Will my pack show the Viagra name, or might it have a different generic or manufacturer name on it?
A
Answered by Support team
The exact trade or manufacturer name on the pack cannot be guaranteed. When it arrives, check that the label states sildenafil, the ordered strength and tablets as the dosage form.
Q
Asked by Georgia F, Edinburgh, United Kingdom
I take tamsulosin for an enlarged prostate. Can I also use sildenafil tablets for erectile dysfunction?
Sildenafil and tamsulosin can both lower blood pressure, so taking them together may cause dizziness, light-headedness or fainting, especially when standing. This combination needs an individual clinical review; sildenafil is generally considered only once the alpha-blocker treatment is stable and with an appropriate starting dose.
