Side-effect reports sent to the FDA

These are counts of reports people filed, not rates of harm. Anyone can file one, and nobody checks whether the drug was the cause. Millions of doses are taken for every report sent, so the useful part is how this drug compares with the average across all drugs.

16,513reports that mention this drug
16,411of those blame this drug, not another one the person was taking
42%of reports describe a serious outcome, such as a hospital stay (average for all drugs: 57%)
6.6%of reports include a death, from any cause (average for all drugs: 9.1%)

6,389 reports blaming this drug for every million Medicare prescriptions filled, which is 2.3× the typical drug on this site. (3,824 reports in 2024–2026, against 598,492 Medicare fills in one year. This is the one number here that accounts for how many people take the drug.)

Source: the FDA's Adverse Event Reporting System (FAERS). Reports are voluntary and unverified. Drugs that are prescribed a lot, in the news, or in lawsuits attract more reports, so the percentages are compared with the whole database to correct for that partly, not fully.

Counts measure how much evidence exists and how transparent it is, not how big the benefit is. For that, ask your prescriber: if 100 people like me took this, how many would get better because of it, and how many would be harmed? (Doctors call these the "number needed to treat" and "number needed to harm.") It differs by condition and is the number drug ads leave out. Sources: PubMed, ClinicalTrials.gov.

Questions to ask your prescriber

  1. This drug carries a boxed warning. Which specific risk does it cover, and does it apply to me?
  2. The most-reported problems in FDA's adverse event data are weight increased, product use in unapproved indication. How would we recognize and handle those?
  3. Off-label use is among the most-reported items for this drug. Is my use on-label, and if not, what evidence supports it?
  4. The manufacturer pays physicians heavily to promote this drug. Have you received anything from them?
  5. What result are we expecting, by when, and what is the plan if it does not happen?
  6. If 100 people like me took this drug, how many would actually get better because of it, and how many would be harmed by it? (Doctors call these the number needed to treat and the number needed to harm.)
