Where the numbers come from

Every number is copied from a table on our side effect pages. Those tables come from FDA labels on DailyMed, results posted on ClinicalTrials.gov, and company trial results. We did not add, total, or rank any number. Rows keep one fixed order: FDA-approved medicines first, then the rest, each in A to Z order.

We group rows by name. For example, “Tiredness (fatigue)” and “Tiredness or weakness (fatigue)” are both under tiredness. Each row still shows its own words from the source.

The tables on this site copy part of each label, such as the most common problems. A problem missing from one table may still have happened.

Report a side effect

You can report a suspected side effect to the FDA at 1-800-FDA-1088 or through FDA MedWatch . If a reaction feels serious, get medical care first.
