What sildenafil is
Sildenafil is a phosphodiesterase type 5 inhibitor. It does not create arousal — it prevents the breakdown of a signalling molecule so that an erection, once initiated, is maintained. Without arousal it does nothing at all, which is the single most common misunderstanding about the drug class and the usual reason someone concludes a product is fake when it is working exactly as designed. This section carries 109 lines from £15 to £145, clustered near £70.
How it behaves
| Sildenafil | Tadalafil | |
|---|---|---|
| Onset | 30–60 minutes | 30–120 minutes |
| Duration | 4–6 hours | Up to 36 hours |
| Food effect | Fatty meals delay it markedly | Minimal |
| Characteristic side effect | Facial flushing, blue visual tinge | Back and muscle ache |
The short duration is an advantage when you want the effect contained, since side effects clear with the drug. The blue visual tinge is characteristic, harmless and transient — it arises because the compound has slight activity against a related enzyme in the retina. The full comparison is in sildenafil versus tadalafil, and the longer-acting option sits in generic tadalafil.
The interaction that actually matters
Sildenafil must not be combined with nitrates. Nitrate medication for angina, taken alongside a PDE5 inhibitor, can cause a catastrophic drop in blood pressure. The same applies to recreational nitrites sold as poppers. This is not a precautionary note — it is the reason these are prescription-only medicines, and the BNF entry maintained by NICE sets out the full interaction profile.
Erectile difficulty is also frequently the first visible sign of cardiovascular disease or of a hormonal problem. Treating the symptom without investigating the cause means missing something that matters considerably more.
Why this category sits alongside anabolic compounds
Suppressed testosterone during and after a cycle commonly affects erectile function, and elevated prolactin from 19-nor compounds does the same by a different route. A PDE5 inhibitor addresses the symptom and nothing else — it does not restore suppressed testosterone, which is what the post cycle therapy range is for. Function that has not returned some weeks after a cycle is a signal to get blood work rather than to keep medicating around it.
Dose, timing and what changes the response
Strengths here run from 25 mg to 100 mg, and higher is not automatically better — the dose-response curve flattens, while facial flushing and headache scale with it. Onset is slowed markedly by a heavy, fatty meal, which is the most common reason a dose appears not to have worked. Alcohol reduces the effect through a separate mechanism, so combining the two works against the outcome twice over.
Where erectile difficulty is driven by suppressed hormones rather than vascular function, a PDE5 inhibitor treats the wrong thing. Our wider erection drugs range covers the alternatives, but blood work is the sensible first step rather than a higher dose.
What is stocked
Listings appear under several names — sildenafil citrate, generic Viagra, Caverta, Vigora and Sildigra among them — all containing the same compound at strengths from 25 mg to 100 mg. Hemi Pharma carries the deepest range, with Euro Pharmacies, Mactropin, Ultima Pharmaceuticals and Para Pharma also represented. Compare on cost per milligram rather than per box, since pack sizes differ substantially across brands.
Legal position and why that matters here
Sildenafil is a prescription-only medicine in the United Kingdom rather than a controlled drug, which is a different offence structure from the anabolic compounds elsewhere in this catalogue. Supplying it without authorisation is an offence under the Human Medicines Regulations 2012; possession for personal use is not.
The practical consequence is that nobody selling it outside a pharmacy setting has assessed whether it is appropriate for you — and with a drug class whose principal contraindication is a fatal blood-pressure interaction, that assessment is the part being skipped. Anyone with cardiovascular history, or taking nitrate medication for any reason, should treat that as disqualifying rather than as a caution to weigh.
Frequently asked questions
Is sildenafilo the same as Viagra?
Yes. Viagra is the original brand name; sildenafil is the compound. Caverta, Vigora and Sildigra are further brand names for the same active ingredient.
How quickly does sildenafil work?
Typically 30 to 60 minutes, and it needs taking on a relatively empty stomach — a heavy, fatty meal can delay onset substantially.
What not to do before taking sildenafil?
Do not take it with nitrates or nitrite poppers in any circumstances. Avoid a heavy fatty meal beforehand, and note that alcohol reduces the effect.
What is sildenafil used for?
Licensed for erectile dysfunction and, at different dosing, for pulmonary arterial hypertension. It requires arousal to produce any effect.
Why did it not work for me?
Most often no arousal, a heavy meal beforehand, alcohol, or an underlying hormonal cause the drug does not address. Repeated failure is a reason to investigate rather than escalate the dose.
