How does headache change across 25, 50, and 100 mg?
Sixteen, twenty-one, and twenty-eight percent in the fixed-dose table, against 7% on placebo (n=312 / 511 / 506 / 607). The type of event in flexible-dose work was similar. Flexible-dose headache was 16% versus 4% (n=734 / 725).
A miserable head on 50 mg is a reason to discuss 25 mg, not a reason to climb. Lowest effective dose is the rating target.
Where is the rest of the 25-100 mg card?
Remaining AE rows sit on the sildenafil panel. Common events also include back pain, myalgia, nausea, dizziness, and rash at ≥2% and more often than placebo. This page led with headache and flush because those are the first rows men bring to the board.
An erection past four hours is not a titration note. That urgent room is the four-hour erection scan.
Where does flushing sit on the same table?
Ten percent at 25 mg, 19% at 50 mg, 18% at 100 mg, versus 2% on placebo. Flexible-dose flushing was 10% versus 1%. Warm face after 50 mg is a known event, not proof the tablet is counterfeit.
Alcohol and a hot room stack on the same vasodilator story. Log the pour on the alcohol scan before you abandon a rung that works.
When do sides say climb down, not up?
If 50 mg already bought a dark-room headache, 100 mg is a louder version of the same row. The label allows a drop to 25 mg when toleration is the problem.
How to rate that step sits on the dose ladder. This scan only shows which events lead the table.
What sits just under headache and flush?
Dyspepsia in the fixed-dose table was 3%, 9%, and 17% versus 2% placebo. Nasal congestion was 4%, 4%, and 9% versus 2%. Both rise toward 100 mg.
Nasal congestion alone rarely justifies leaving a rung that works. Dyspepsia that wrecks the evening is a fair step-down talk.
Is a color tinge the same as a vision stop?
Abnormal vision in fixed-dose work was 1%, 2%, and 11% versus 1% placebo, usually a mild, transient color tinge or light sensitivity. Sudden loss in one or both eyes is a different event. Stop the class and seek care. That stop lives on the vision scan.
Only one flexible-dose patient discontinued for abnormal vision in those studies. A tinge is not automatic proof you must leave 50 mg.
