Viagra Tablets (Sildenafil Citrate) 25 mg, 50 mg & 100 mg

Choosing Viagra over another sildenafil-based option often comes down to one practical distinction: it is the original branded film-coated tablet, supplied by us in three clearly separated strengths. That matters when you are comparing options, because it lets you start at a dose your GP, prescriber or pharmacist considers appropriate, then adjust upward or downward within the same familiar product range rather than changing formulation. Everything below explains what that means for your routine, safety, expected results, and how ordering and delivery work.

What exactly are these Viagra tablets?

The tablets we list here are film-coated tablets taken by mouth. They contain sildenafil, supplied as sildenafil citrate, and belong to the phosphodiesterase type 5 (PDE5) inhibitor class. The ATC code for sildenafil used in erectile dysfunction is G04BE03. We supply 25 mg, 50 mg and 100 mg strengths of the standard oral Viagra tablet rather than a soft, chewable or fast-dissolving variant.

If you have seen other sildenafil-based names in wider circulation, it is worth checking the formulation rather than assuming every option is interchangeable in practical use. This guide applies specifically to Viagra film-coated tablets in the listed strengths. The active medicine may also be available in authorised generic products, but appearance, inactive ingredients, packaging and brand price can differ even when the active ingredient and strength are the same.

Viagra is an on-demand treatment for erectile dysfunction in adult men. It does not cure an underlying vascular, hormonal, neurological or psychological cause, and it is not an aphrodisiac. Its role is to improve the erectile response to sexual stimulation for a limited period after a dose.

Who may consider Viagra, and what factors should guide the decision?

Viagra may be considered by adult men who have difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity. Erectile dysfunction can have more than one cause, including vascular or neurological changes, diabetes, hormonal factors, medicine side effects, anxiety, relationship pressures and other psychological contributors. New, persistent or worsening symptoms deserve medical assessment because erectile dysfunction can sometimes be an early sign of cardiovascular or metabolic disease.

Because sildenafil acts on a specific pathway rather than treating the underlying cause, it suits men who want an on-demand approach around anticipated sexual activity rather than regular daily dosing. The decision should take account of the following factors:

• Your general cardiovascular health and whether sexual activity is medically advisable, since sildenafil affects blood vessel tone and interacts significantly with nitrate medicines.
• Any other regular or occasional medicines, particularly those used for chest pain, blood pressure, prostate symptoms, HIV, fungal infections or erectile dysfunction.
• Whether you have diabetes, which is a recognised cause of erectile dysfunction rather than a sildenafil-specific contraindication.
• Kidney or liver function, since impairment can affect how sildenafil is cleared and may make a lower starting dose appropriate.
• Your previous response to sildenafil, including whether the timing, meal, stimulation and number of properly used attempts were adequate before concluding that a dose did not work.
• Age: these erectile-dysfunction tablets are intended for adult men and are not indicated for anyone below 18 years of age.

A clinical discussion is especially useful if erectile dysfunction appeared suddenly, is accompanied by reduced sexual desire, penile pain or curvature, or occurs alongside breathlessness or chest symptoms. Treating the symptom should not replace investigation of a potentially important underlying condition.

How does Viagra work, and what does that mean in practice?

During sexual stimulation, nitric oxide released in penile tissue increases cyclic guanosine monophosphate, usually shortened to cyclic GMP or cGMP. This chemical signal relaxes smooth muscle and helps blood enter the penis. Sildenafil blocks the PDE5 enzyme that normally breaks down cGMP, allowing that natural signal to have a greater effect.

The practical result is that blood flow can increase more readily when sexual stimulation is present. Viagra does not create desire, cause automatic arousal or produce a continuous erection on its own. This is why it is taken in anticipation of sexual activity rather than as a general background stimulant. If stimulation is absent, the medicine may appear not to work even when it has been absorbed normally.

The effect also depends on correct timing and realistic expectations. Anxiety, substantial alcohol intake, a heavy meal or insufficient stimulation can all affect the result. A lack of benefit from one attempt does not necessarily establish treatment failure, but the dose must not be repeated within the same 24-hour period to compensate.

How do you take Viagra and build a routine around it?

General use follows a straightforward pattern, although a prescriber may adjust the dose for your health, other medicines and previous response.

1. Take one tablet as a whole dose, generally around 30 to 60 minutes before anticipated sexual activity.
2. Swallow it with water. It can be taken with or without food, but a heavy or high-fat meal can delay absorption and make the onset less predictable.
3. Limit alcohol intake. Excessive alcohol can make it harder to obtain an erection and can increase effects such as dizziness or low blood pressure.
4. Take no more than one dose in any 24-hour period, even if the first attempt does not produce the expected response.
5. Allow time and sexual stimulation to occur, since the tablet supports rather than replaces the natural erectile response.

The usual recommended dose for many adults is 50 mg when needed, with adjustment to 25 mg or 100 mg according to effectiveness and tolerability. The maximum recommended dose is 100 mg once per day. A lower starting dose may be considered for people with significant liver or kidney impairment or when sildenafil is combined with certain interacting medicines. Do not split or combine tablets to alter a dose unless a qualified professional has confirmed that approach for the specific tablets supplied.

Viagra is not normally taken on a fixed schedule, so there is no missed dose to make up. If you do not use a planned dose, simply leave it and take the next dose only when needed. Never take two doses together.

Available strengths and exact pack choices

We list Viagra film-coated tablets in 25 mg, 50 mg and 100 mg. The available quantities vary by strength. For 25 mg tablets, we offer packs of 20, 30, 60, 90, 120, 180, 270 and 360 pills. For both 50 mg and 100 mg tablets, we offer packs of 10, 20, 30, 60, 90, 120, 180, 270 and 360 pills.

Strength is more important than simply choosing the largest pack or the lowest per-tablet price. The 50 mg tablet is a common starting point, but 25 mg may be appropriate when tolerability, interacting medicines or reduced clearance is a concern. The 100 mg strength is the maximum recommended single dose and is not automatically a better first choice. If 50 mg is ineffective despite correct use, dose adjustment should be discussed rather than attempted independently.

Pack quantity is a separate decision. A smaller pack may be practical while establishing how the treatment fits your circumstances. A larger pack may suit someone who already has an established dose and expects ongoing intermittent use. Check the selected strength and quantity carefully at checkout, as changing the number of tablets does not change the dose contained in each tablet.

Expected onset, duration and results

Many men notice an effect within 30 to 60 minutes of taking sildenafil. It may begin working sooner for some people, while food can delay the onset. The useful response window is commonly around four hours, although the medicine gradually becomes less effective over that period and individual experience varies.

A four-hour window does not mean that an erection should last for four hours. It means an erection may be easier to achieve in response to stimulation during that period. Any erection lasting longer than four hours requires urgent medical help because prolonged erection, or priapism, can damage penile tissue.

When assessing whether Viagra works, consider the dose, timing, meal, alcohol intake and stimulation together. Repeated lack of response despite correct use should be discussed with a GP or pharmacist. Increasing the dose beyond 100 mg or combining sildenafil with another erectile-dysfunction medicine is not an appropriate way to overcome poor response.

Important safety priorities before ordering

Common side effects

• Headache and facial flushing, which are among the most frequently reported effects.
• Indigestion, nausea or an upset stomach.
• Nasal congestion.
• Visual disturbances, such as blurred vision, a blue tinge to vision or increased sensitivity to light.
• Dizziness, which can affect your ability to drive, cycle or operate machinery until you know how you respond.

These effects are often temporary, but persistent or troublesome symptoms should be discussed with a healthcare professional. Avoid driving or operating machinery if you feel dizzy or notice altered vision.

Contraindications and situations requiring assessment

• Do not use Viagra with nitrate medicines, nicorandil or recreational nitrate products known as poppers, because the combination can cause a dangerous fall in blood pressure.
• Do not use it with riociguat, as the combined blood-pressure-lowering effect is contraindicated.
• Do not take it if you are allergic to sildenafil or any ingredient in the tablet.
• Seek individual advice if you have severe cardiovascular disease, very low blood pressure, a recent heart attack or stroke, severe liver impairment, certain inherited retinal disorders, or previous loss of vision due to non-arteritic anterior ischaemic optic neuropathy.
• These erectile-dysfunction tablets are not indicated for women or people below 18 years of age.

Symptoms needing urgent help

Seek urgent medical assistance for an erection lasting longer than four hours, sudden loss or marked reduction of vision, sudden hearing loss, a severe allergic reaction or chest pain during or after sexual activity. If chest pain occurs, do not take a nitrate to treat it after using sildenafil; tell the healthcare professional when sildenafil was taken.

Suspected side effects in the UK can be reported through the MHRA Yellow Card Scheme. Reporting does not replace seeking medical care when symptoms are serious.

Medicine interactions and practical precautions

Beyond nitrates and riociguat, several medicine groups deserve attention before sildenafil is used. Alpha-blockers prescribed for high blood pressure or prostate symptoms can add to its blood-pressure-lowering effect. A clinician may recommend that alpha-blocker treatment is stable before sildenafil is introduced and may choose a lower sildenafil starting dose.

Certain CYP3A4 inhibitors can increase sildenafil exposure. These include some azole antifungals, macrolide antibiotics and medicines used to treat HIV. Grapefruit or grapefruit juice may also affect sildenafil metabolism in some people, so avoiding large quantities is a sensible precaution. CYP3A4 inducers, such as rifampicin, may reduce sildenafil exposure and effectiveness.

Combining Viagra with another PDE5 inhibitor or another erectile-dysfunction treatment is not recommended. The effects do not add in a reliably useful way, while adverse effects such as low blood pressure, headache and prolonged erection may become more likely. Always include non-prescription medicines, supplements and recreational drugs when discussing interactions.

The interaction guide highlights the main groups, but it cannot account for every medicine or health condition. If your treatment changes, check compatibility again rather than relying on advice given for an older medicine list.

Viagra, Levitra or Cialis: which suits your situation?

Sildenafil is one of several PDE5 inhibitors. The practical differences in onset, duration, food effects and dosing patterns often matter more to an individual choice than a general claim that one medicine is universally superior.

Vardenafil, sold under the Levitra brand, has a broadly similar on-demand role and duration to sildenafil. Its absorption can also be delayed by a high-fat meal. Individual response and contraindications still need to be considered, so switching is not simply a matter of matching tablet strengths milligram for milligram.

Tadalafil, sold under the Cialis brand, offers a notably longer response window, commonly cited as up to 36 hours, and food has less effect on its absorption. It can be prescribed for on-demand use and, at suitable lower strengths, as a daily regimen. That longer duration may suit people who prefer less precise timing, whereas Viagra's shorter window may suit those who want treatment focused on a particular occasion.

All three medicines belong to the same broad class and share important precautions, particularly around nitrates and cardiovascular suitability. Do not move between them, combine them or assume equivalent doses without professional guidance.

UK prescription status and our ordering policy

Viagra 25 mg, 50 mg and 100 mg film-coated tablets remain classified as prescription-only medicines in the UK. That regulatory classification is separate from the documentation our checkout asks customers to provide.

Under our ordering policy, you do not need to submit a prescription document before we accept an order for this product. This does not make the medicine non-prescription in the UK or remove the need to use it safely. We recommend discussing sildenafil with a GP or pharmacist beforehand, particularly if you take other medicines, have cardiovascular concerns or are uncertain which strength is suitable.

Our pharmacist-supported team is available 24 hours a day, seven days a week, by email, online chat and phone if you would like product or ordering guidance. Support can help clarify the available options, but urgent symptoms and decisions about whether sexual activity is medically advisable require appropriate clinical care.

Ordering, delivery and receiving your Viagra tablets

We have operated since 2017, and our checkout is set up in pounds sterling for customers ordering to the UK. A few practical points are worth checking before you place an order:

• Confirm both the strength and tablet quantity. Available pack sizes are shown against each strength on this listing.
• Review your delivery address and postcode carefully before completing checkout to reduce avoidable delivery problems.
• Support is available 24/7 through email, online chat and phone, with a pharmacist available for product questions.
• We treat delivery timings as estimates rather than guarantees, and our support team can assist with tracking or delivery queries after dispatch.
• When the parcel arrives, check that the product name, strength and quantity match your order before taking a tablet.

Keep Viagra in its original packaging, away from children, and store it at 25°C; permitted temperature excursions are between 15°C and 30°C. Do not use tablets that are damaged, have been stored improperly or are past the stated expiry date.

If erectile dysfunction has several contributing causes for you, it can also help to review other options in our Erectile Dysfunction range while deciding which treatment pattern best fits your circumstances.

Making your decision

Viagra's central distinction is familiarity: it is a well-established branded sildenafil tablet available here in three strengths, with an on-demand dosing pattern built around anticipated sexual activity rather than daily commitment. It may be a suitable choice if you value a shorter, occasion-focused response window and already understand how meals, alcohol and timing can affect the result.

The right strength should balance response with tolerability. The right pack quantity depends on whether you are establishing a dose or maintaining an approach that already works for you. Neither a higher strength nor a larger pack replaces the need to check contraindications and interactions.

If a longer window of effect or less sensitivity to food matters more, the Levitra and Cialis comparisons above show where an alternative may fit. Whichever option you consider, reviewing your regular medicines, cardiovascular health and previous treatment response with a GP, prescriber or pharmacist can help you choose a safer and more practical routine.
