This grade answers one narrow question: how strong is the public evidence and safety record behind this drug, and how clean is its money trail and court record? It is not a verdict on whether the drug is right for you.

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.

4,024reports that mention this drug
4,008of those blame this drug, not another one the person was taking
72%of reports describe a serious outcome, such as a hospital stay (average for all drugs: 57%)
9.1%of reports include a death, from any cause (average for all drugs: 9.1%)

Independent Cochrane reviews

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.

Money and lawsuits

In 2024, drug companies reported $14,679 in payments to US physicians and hospitals tied to this drug across 877 transactions (Secuado $14,679).

No pending federal MDL names this drug or its brands.

Not named in any federal pharmaceutical settlement of $100M or more on record.

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. In 2011 the FDA issued a safety communication about this drug (Saphris (asenapine maleate) - Serious allergic reactions reported with the use of Saphris (asenapine maleate)). Does that risk apply to me?
  2. This drug carries a boxed warning. Which specific risk does it cover, and does it apply to me?
  3. The most-reported problems in FDA's adverse event data are suicide attempt, sedation, dyskinesia. How would we recognize and handle those?
  4. Why this one over clothiapine, clozapine, loxapine? What would make you pick one of those instead?
  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.)
