01What the label starts most men on
Fifty milligrams as needed, about one hour before sexual activity, is the recommended dose for most patients. Once per day is the frequency cap.
A holiday strip of 100 mg does not rewrite that first-night sentence.
02Why a holiday 100 strip is not a start
A 100 mg blister from another country is still the ceiling tablet. Bring it to the visit as history, not as the first US swallow.
If 50 mg was never given a clean night, skipping to 100 skips the start row.
03What 100 mg is after a trial
After a real 50 mg trial - arousal present, limited alcohol, food handled - the insert allows 100 mg. Side effects that already dominate at 50 mg will not improve at 100.
Sibling: 25, 50, and 100 mg names the three US tablets.
04Why this vault features 25 and 50
25 mg is a labelled tablet and the consider-start when age, liver, severe kidney, alpha-blockers, or strong CYP3A4 inhibitors pull the first swallow down. 50 mg is the usual adult start when those rows are clean.
Featuring both keeps the step-down in the same band as the usual start. It is not a claim that everyone begins at 25 mg.
05How the dose-rung pulse holds the step-down list
Who stays at 25 mg on purpose, what counts as an honest 50 mg trial, and the ritonavir 48-hour cap are walked on the dose-step pulse. This probe only answers what the label starts and what this vault features.
Monograph detail for 25 mg and 50 mg sits on the sildenafil 25-50 mg vault.
06When 25 mg is the directed first swallow
Age over 65, hepatic impairment, creatinine clearance under 30 mL/min, and several interacting drugs all say consider 25 mg. Ritonavir is stricter: 25 mg and not again for 48 hours.
The dose-step pulse holds that list without turning this page into a second copy.
