01How soon can Fildena 100 start if it is sildenafil?
Plan about one hour on a lighter stomach. The labelled window is 30 minutes to 4 hours. Purple ink does not shorten the wait.
Sitting on the clock without stimulation is not the labelled experiment. The stimulation probe is that step.
02What did Eardley count at four hours on 100 mg?
When visual sexual stimulation began 4 hours after 100 mg, 13 of 16 men (81 percent) were responders versus 5 of 16 (31 percent) on placebo. Median duration of grade 3 or 4 erections at that mark was 5 minutes on sildenafil versus 0 minutes on placebo.
That count is why counselling still talks about a four-hour window on 100 mg. It is not a promise that every Sunday lasts four hours.
03Who still needs stimulation inside the window?
Anyone who swallowed sildenafil, including a Fildena 100 mg pocket. The hour opens a chance. It does not start nitric oxide by itself.
Chest pain, a four-hour erection, or sudden vision or hearing loss is emergency care, not a timing tweak.
04Should you glue later clock trials onto this page?
No. Eight-hour and twelve-hour n/N belong to other protocols. This probe stays on the labelled 30-minute to 4-hour window and the 100 mg four-hour count.
Gluing those later clocks here would be a second study in the same room. The job is already answered.
05Why plan about an hour on a lighter stomach?
Fasting Tmax sits between 30 and 120 minutes, median 60. That median is the 'about an hour' sentence. Most RigiScan work on the US file assessed effect around 60 minutes after the dose.
The time-course study on the file showed an effect out to 4 hours that was smaller than at 2 hours. Smaller is not zero. It is also not a reason to swallow a second 100 mg.
06Does a high-fat dinner steal that hour?
It can. Mean Tmax moves about 60 minutes later and Cmax can drop about 29 percent. The food-delay probe is the meal page.
Do not treat a late peak as a failed strip and add a second tablet. Once a day still applies.
