Sildenafil 100mg Film-Coated Tablets

Sildenafil 100mg Film-Coated Tablets (UK Licensed Generic Viagra)

Prescription sildenafil 100mg film-coated tablets from Milpharm, a UK MHRA licensed generic. Sildenafil is the same active ingredient, at the same strength, as branded Viagra. Used to treat erectile dysfunction (ED) in adult men. UK prescriber review at checkout, dispensed by a GPhC registered UK partner pharmacy.

Supplied in the manufacturer's original box of 4 tablets.

How sildenafil works

Sildenafil is a phosphodiesterase type 5 (PDE-5) inhibitor. It relaxes the smooth muscle in the walls of blood vessels supplying the penis, allowing increased blood flow when you are sexually aroused. It does not cause an erection on its own; sexual stimulation is still required.

100mg is the maximum single dose of sildenafil. Many men are started at 50mg to assess response, and only step up to 100mg if 50mg is not effective enough. If you have not taken sildenafil before, say so in the health questionnaire so the prescriber can start you at the right strength.

How to take

• Take one tablet 30 to 60 minutes before you plan to have sex

• Effects typically last around 4 hours

• Do not take more than one dose in 24 hours

• Sexual arousal is still needed; sildenafil does not work without stimulation

• A heavy meal or excess alcohol before taking can delay or reduce the effect. Take on a relatively empty stomach for the best onset

• Avoid grapefruit and grapefruit juice, which can increase sildenafil blood levels

Side effects

Sildenafil is well tolerated by most men when taken as directed. Most side effects are mild and short-lived.

Very common (more than 1 in 10)

• Headache, often mild, and tends to resolve within 2 to 4 hours

Common (roughly 1 in 10)

• Facial flushing

• Indigestion or heartburn

• Nasal congestion

• Mild dizziness

• Blue-tinged vision or light sensitivity, temporary, resolving in 4 to 6 hours

Uncommon (roughly 1 in 100)

• Chest tightness

• Blurred vision

• Palpitations

• Skin rash

Rare (less than 1 in 1,000)

• Priapism, a painful erection lasting more than 4 hours. Medical emergency, see below

• Sudden hearing loss, usually in one ear. Medical emergency, see below

• Serious cardiovascular events including heart attack, stroke, or a dangerous drop in blood pressure

When to seek urgent medical advice

• Priapism: an erection lasting more than 4 hours needs A&E. Untreated priapism can cause permanent damage

• Sudden hearing loss or ringing in the ears: needs urgent review

• Chest pain, severe dizziness or fainting during or after sexual activity: call 999

• Sudden vision changes beyond a mild blue tint, such as dark spots or vision loss: needs urgent review

• Signs of allergic reaction: facial or lip swelling, difficulty breathing, widespread rash

Who should not take sildenafil

Sildenafil is not safe for everyone. Do not take it if you:

• Take any nitrate medicine such as GTN spray, isosorbide, amyl nitrite or "poppers". Combined use can cause a life-threatening drop in blood pressure

• Take riociguat or other guanylate cyclase stimulators

• Have had a heart attack, stroke, or serious heart-rhythm event in the last 6 months

• Have unstable angina, severe heart failure, or uncontrolled high or low blood pressure

• Have severe liver disease

• Have a hereditary eye condition such as retinitis pigmentosa

• Have previously had priapism, or have sickle-cell disease

• Are under 18 or female. Sildenafil is not licensed for these groups for ED

Drug interactions to disclose

Tell your prescriber if you take any of the following, because doses may need adjustment:

• Alpha-blockers, for blood pressure or the prostate, which need time-spacing

• Ritonavir, ketoconazole or itraconazole, which raise sildenafil blood levels significantly

• Erythromycin or clarithromycin

• Cimetidine, a heartburn medicine

• Other ED medicines such as tadalafil, vardenafil or avanafil

Generic sildenafil and branded Viagra

They are clinically the same medicine. Both contain sildenafil at the same strength, both are held to the same MHRA bioequivalence standard, and both produce the same clinical effect and the same side-effect profile. Generic sildenafil is standard practice in UK ED prescribing.

The honest differences are narrow:

• Manufacturer: this product is made by Milpharm. Branded Viagra is made by Pfizer, the original patent holder

• Recognition: some men specifically want the name they have heard of

• Price: the generic costs substantially less

Prescription included

Sildenafil vs Viagra vs Cenforce vs Kamagra vs Tadalafil (Cialis)

UK men researching erectile dysfunction medication run into a lot of brand names. The active differs less than the marketing suggests. Here is the honest map:

• Viagra 100mg (Pfizer): the original branded sildenafil. Same active as generic sildenafil, dispensed under Pfizer branding. Typically £25 to £40 per tablet at UK pharmacies. Effective, expensive, unnecessary if generic is available.
• Milpharm generic sildenafil 100mg (this product): MHRA licensed UK generic sildenafil, manufactured by Milpharm (a UK generics maker). Same active at the same 100mg dose as Viagra, at a fraction of the price. Available at £10 for a small pack down to a much lower per-tablet cost on the 96 tablet value pack.
• Cenforce 100mg (Centurion Laboratories, India): we discontinued this product on 10 September 2026. Cenforce is Indian import sildenafil sold without a UK MHRA licence. Cheap online but grey market: no independent UK quality audit, occasional counterfeits, no aftercare route if something goes wrong. Our Milpharm generic sildenafil is the UK licensed direct equivalent.
• Kamagra (Ajanta, India): another Indian import sildenafil, sold as tablets or oral jelly. Not MHRA licensed. Same active as Viagra but same grey market concerns as Cenforce. Avoid.
• Tadalafil (Cialis): different molecule, much longer half-life (~17.5 hours versus ~4 for sildenafil). Marketed as the "weekend pill" because a single dose can cover activity across 24 to 36 hours. Better for men who want spontaneity, worse if the shorter Sildenafil window is preferred.
• Vardenafil (Levitra): similar to sildenafil in onset and duration. Slightly higher tolerance in men who get flushing on sildenafil.
• Avanafil (Spedra): the fastest onset of the PDE5 inhibitors, ~15 minutes vs 30 to 60 for sildenafil. Newer and more expensive per tablet.

For most UK men wanting a generic effective ED medication at the lowest cost, Milpharm sildenafil 100mg is the mainstream first-line choice. Cialis is the alternative if a longer window is preferred. Everything else is either branded overspend or grey market import risk.

Clinical evidence for sildenafil

Sildenafil has 25+ years of clinical evidence and is one of the most prescribed medications in the world. Key findings:

• Goldstein et al 1998 (original Pfizer Phase III trials, 861 men): sildenafil 100mg produced successful intercourse in 69% of attempts versus 22% on placebo. Effective across a broad range of erectile dysfunction causes: diabetes, cardiovascular, post-prostatectomy, psychological.
• Dose response: 25mg, 50mg and 100mg are all effective. Higher doses do not extend duration but do improve rigidity and reliability, particularly in men with vascular ED. Most UK prescribers start at 50mg and adjust up or down based on effect and tolerance.
• Onset and duration: effective from 30 to 60 minutes after taking, peak effect at ~90 minutes, useful window of 4 to 6 hours. High-fat meals delay onset by 30 to 60 minutes; take on an empty stomach or after a light meal for fastest onset.
• Real-world effectiveness: the 100mg dose is effective in roughly 70 to 85% of men across published studies. Failure to respond at 100mg after 8 or more attempts (properly timed, without excessive alcohol) is the typical trigger to consider tadalafil or vardenafil instead.

Regulatory status in the UK: POM, MHRA licensed

• Sildenafil is a POM (prescription only medicine) in the UK at the 100mg strength. Sildenafil 50mg is also POM. Sildenafil 25mg has been available as a P (pharmacy) medicine over the counter under the brand Viagra Connect since 2018, following a pharmacist check-in.
• Milpharm sildenafil 100mg is MHRA licensed. Same clinical file as branded Viagra, manufactured at MHRA-audited UK facility, same active pharmaceutical ingredient at the same dose.
• Free UK prescriber review at checkout: the online medical questionnaire is reviewed by a UK GPhC registered prescriber before dispensing. This assesses cardiovascular fitness for the drug, any nitrate medications, and other contraindications.
• Dispensed by a GPhC registered UK partner pharmacy. Every pack is prepared and shipped in the UK, not imported from India or elsewhere. Discreet plain packaging.
• Import risk: unlicensed sildenafil sold online from India or Turkey (Cenforce, Kamagra, generic Viagra imports) is not MHRA quality-controlled. Some batches audited by regulators have contained under-dosed or contaminated tablets. Not recommended.

Storage and shelf life

• Store at room temperature (below 30°C), away from direct sunlight and moisture. Do not refrigerate.
• Keep tablets in the original blister pack or bottle until you take them. The blister foil protects the tablet from moisture and light.
• Sealed pack expiry is printed on the pack (typically 24 to 36 months from manufacture). Do not use after the printed expiry date.
• Keep out of reach of children and pets. Sildenafil can cause serious cardiovascular events if taken by someone on nitrates or with severe heart disease.
• Do not share tablets with anyone else. Every user needs their own prescriber review to confirm sildenafil is safe for them personally.

Excipients: what is in each Milpharm sildenafil 100mg tablet
