Sildenafil tablets are a treatment for erectile dysfunction in adult men. Sildenafil is the same active ingredient found in Viagra, supplied here as the generic version, and it is taken ahead of sexual activity rather than daily. It is a medicine that requires a clinician to assess whether it is suitable for you.
Sildenafil is a phosphodiesterase type 5 inhibitor, or PDE5 inhibitor. Sexual arousal causes the blood vessels supplying the penis to relax and fill, and PDE5 is the enzyme that reverses that process. Blocking it allows an erection to develop more easily and to be sustained. It does not create arousal, which is why sexual stimulation is still needed for it to do anything at all.
Swallow one tablet with water around an hour before sexual activity, following the directions given by your clinician, and do not take more than one dose in 24 hours. A large or fatty meal slows absorption and delays the effect, and alcohol can blunt it. If the first attempt does not work, that is common; the medicine is usually judged over several occasions rather than one.
It is for adult men where a clinician has confirmed it is appropriate. It must not be taken with nitrates for chest pain or with amyl nitrite, and your clinician needs to know about heart conditions, a recent stroke or heart attack, low or uncontrolled blood pressure, liver or kidney problems, retinitis pigmentosa, and every other medicine you take.
Headache, flushing, indigestion, a blocked nose and visual disturbances such as a blue tinge are among the reported effects. Seek urgent medical help for chest pain during sex, an erection lasting more than four hours, or sudden loss of vision or hearing. Erectile dysfunction can be an early sign of cardiovascular disease or diabetes, so it is worth having the wider picture checked rather than treating the symptom alone. Our UK pharmacy team can answer questions about this product before you buy.
Is it the same as Viagra?
It contains the same active ingredient. Generic versions are assessed to the same standards.
Does food affect it?
Yes. A large or fatty meal slows absorption and delays the effect.
It did not work the first time. Why?
That is common. Timing, food, alcohol and anxiety all play a part, and it is usually judged over several occasions.
Always read the patient information leaflet supplied with the pack before use.
