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.

21,902reports that mention this drug
21,884of those blame this drug, not another one the person was taking
37%of reports describe a serious outcome, such as a hospital stay (average for all drugs: 57%)
2.8%of reports include a death, from any cause (average for all drugs: 9.1%)

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.

Same-class alternatives

antazolinecromolynlevocabastinenedocromilthonzylamine

Same ATC pharmacological class, graded ones first, best grade at the top. Being in the same class does not make them interchangeable for your condition; it makes them worth asking about.

Questions to ask your prescriber

  1. The most-reported problems in FDA's adverse event data are treatment failure, fatigue, headache. How would we recognize and handle those?
  2. Why this one over antazoline, cromolyn, levocabastine? What would make you pick one of those instead?
  3. What result are we expecting, by when, and what is the plan if it does not happen?
  4. 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.)
