Most-Reported Reactions
Counts of the reactions most often cited in FAERS submissions that named Tadalafil. Inclusion here does not establish causation - submitters describe what was observed, not what was confirmed. One submission can list several reactions, so the totals exceed the report count.
Patient Demographics
Patient sex and age across the FAERS submissions that named Tadalafil. Percentages here are computed only from submissions where these fields were filled in - many leave them blank.

Severity Outcomes
Severity flags recorded across the 98,082 FAERS submissions that named Tadalafil. Each bar shows the count of those reports carrying that flag. A single case can carry more than one (a hospitalization that became life-threatening, for example), so these bars are independent rates - they don't sum to 100%. Inclusion of a case under any flag does not establish that the drug caused the outcome.
Submissions Per Quarter
Quarterly count of FAERS submissions that named Tadalafil. Ups and downs on this chart can track prescribing volume, news cycles, or shifts in how reports get filed, rather than the drug becoming safer or more dangerous.

Tadalafil was administered to over 9000 men during clinical trials worldwide. In trials of tadalafil tablets for once daily use, a total of 1434, 905, and 115 were treated for at least 6 months, 1 year, and 2 years, respectively.
