Cenforce vs Viagra: how the sildenafil generic differs from the original
The active substance in original Viagra and generic Cenforce tablets is the same — sildenafil citrate. The same molecule is in Malegra, Kamagra Oral Jelly and Revatio. The full list of forms and prices across all dosages is on the sildenafil substance page.
This article does not replace a doctor's consultation and does not choose a dose for you personally. It explains what the leaflet says and what genuinely differs between the products on the shelf. The decision to take it, especially with any cardiovascular condition, belongs to a doctor.
One molecule, different packs
Viagra is the original drug from Pfizer, the first sildenafil to reach the market in the late 1990s. Its patent protection ended long ago, and dozens of manufacturers now produce the same sildenafil citrate under their own names. Cenforce is one such generic, made by the Indian company Centurion Laboratories.
The difference between the original and the generic is a difference in manufacturer, packaging and price — not in the active substance. Both work the same way: they increase blood flow by blocking the PDE5 enzyme, but only during sexual arousal — the drug itself does not cause an erection on its own.
One important distinction is regulatory: original Viagra goes through a full quality-control and clinical-trial cycle in its country of registration. Generics like Cenforce are manufactured to their home country's standards and are not always registered in Ukraine, so it is worth checking what is legally allowed for import and sale before ordering, and consulting a doctor or urologist rather than self-medicating in any case.
Cenforce vs Viagra compared

Cenforce forms are not just "a different dose"
100–200 mg
swallowed with water, effect in 30–60 minutes
Sublingual
absorbed through the mucosa, faster onset
Sildenafil + dapoxetine
has its own antidepressant interactions — see below
- Cenforce 100, 150, 200 — regular tablets that differ only in the sildenafil dose.
- Cenforce Soft — a chewable form with the same effect, no water needed.
- Cenforce Professional — a sublingual form; absorption through the mucosa means a faster onset than a regular tablet.
- Cenforce-D — sildenafil combined with dapoxetine (used for premature ejaculation control). Dapoxetine has its own contraindications, most notably incompatibility with SSRI antidepressants and MAO inhibitors — another reason not to choose this combination without a doctor.
- Cenforce FM — a form sometimes marketed "for women." The evidence for sildenafil's effectiveness in female sexual dysfunction is considerably weaker than for male erectile dysfunction, so this decision belongs to a gynecologist regardless.
When sildenafil cannot be taken in any form
This applies equally to original Viagra and any sildenafil generic — Cenforce, Malegra or Kamagra — since the substance and its limits are the same.
- Nitrates are strictly forbidden. Nitroglycerin and any nitrate-based medicine (often prescribed for angina) combined with sildenafil can cause a sharp, life-threatening drop in blood pressure. This is the single most serious contraindication, and it is absolute.
- Severe cardiovascular disease: a recent heart attack or stroke, unstable angina, severe heart failure.
- Uncontrolled low or high blood pressure.
- Severe liver or kidney impairment — only a doctor can decide the dose or whether it can be taken at all.
- Taking alpha-blockers at the same time requires caution and medical supervision due to the risk of a sharp blood pressure drop.
Common but non-dangerous side effects include headache, facial flushing, nasal congestion, and a mild bluish tinge to vision. If any of the conditions above apply to you, that is a reason to see a doctor first rather than choose a dose on your own.
Original or generic
If a doctor has no objections and the product is legal to sell, the difference between Viagra and Cenforce is mainly price and manufacturer, not effect — the molecule is identical. It is usually recommended to start with a lower dose (25–50 mg of sildenafil) rather than Cenforce's maximum 200 mg right away. Taking it on an empty stomach or after a light meal speeds up absorption; fatty food, on the other hand, delays the onset.
