In brief
- Viagra Generic (sildenafil) is an imported generic containing the same active ingredient as Viagra, prescribed for erectile dysfunction in adult men.
- The listing runs from 25 mg to 200 mg across seven strengths, whereas the UK SmPC allows no more than 100 mg per 24 hours.
- Sildenafil needs sexual stimulation to work, and suitability is something your doctor or prescriber must judge.
Viagra Generic: sildenafil from outside the UK market
Viagra Generic is a generic tablet imported from abroad. It holds sildenafil, the active ingredient of Viagra, and is intended for adult men whose erections are hard to get or hard to keep through intercourse. The way it works is a matter of chemistry: during arousal nitric oxide in the penis raises cyclic GMP, which relaxes the vessel walls and lets blood in, and the enzyme PDE5 normally removes cGMP again. Sildenafil blocks PDE5, which prolongs the effect. If there is no arousal, nothing happens, and desire is not altered.
Strengths on offer against the UK limit
Seven strengths are on the page, from 25 and 50 mg through 100, 120, 130 and 150 mg up to 200 mg, and a pack can hold anything from 10 to 360 tablets. UK licences cover three of those, 25, 50 and 100 mg, and the SmPC fixes the daily maximum at 100 mg, one dose per 24 hours. The remaining four strengths, 120 mg and above, lie outside any UK authorisation. The cap exists because unwanted effects become commoner as the dose climbs, and nothing in the SmPC supports a bigger tablet of Viagra Generic.
Starting dose and adjustments in the SmPC
The SmPC begins with 50 mg about an hour before sex; depending on effect and tolerance, the prescriber may drop to 25 mg or rise to 100 mg. A large meal beforehand may delay the effect. The lower 25 mg start applies to severe kidney impairment, liver impairment and combinations with CYP3A4 inhibitors like erythromycin or itraconazole, while ritonavir is not advised at all. Anyone taking an alpha-blocker should be on a steady dose before sildenafil is added. Age alone does not require a change, and the same rules apply to Viagra Generic.
Where Viagra and sildenafil sit in UK law
Viagra was first authorised in Britain in 1998 and Viatris now holds the licence. All three Viagra tablet strengths (25, 50 and 100 mg) sit in the prescription-only (POM) category. Elsewhere in the sildenafil family, the legal class (POM or pharmacy-only, P) follows each product’s own authorisation; Viagra Connect 50 mg, for instance, is a P product that a pharmacist may supply after checking suitability, up to one 50 mg tablet a day. These authorisations do not extend to Viagra Generic.
Health conditions and medicines that block sildenafil
Never combine sildenafil with a nitrate (GTN, isosorbide mononitrate), with a nitric oxide donor such as amyl nitrite, or with riociguat: together they can drop blood pressure dangerously. The SmPC also excludes men told to avoid sexual exertion for cardiac reasons, a stroke or heart attack in the recent past, resting blood pressure under 90/50 mmHg, severe liver disease, inherited retinal problems such as retinitis pigmentosa, and loss of vision in one eye from NAION. The prescriber will want extra reassurance where there is a curved or deformed penis (Peyronie’s disease), sickle cell disease, myeloma, leukaemia, a bleeding disorder or a peptic ulcer that is active. Those cautions apply equally to Viagra Generic.
Common reactions, and signs that need urgent care
The commonest complaint is headache; after it come flushing, giddiness, sickness, heartburn, a stuffy nose and visual changes, for example blurring or a blue cast over colours. An erection lasting four hours or more is an emergency, as is any sudden worsening or loss of vision; go to A&E or call 999. Viagra Generic should be taken only as your doctor or prescriber directs.
