Adverse reactions (label)

Most common adverse reactions (incidence ≥ 1%) are application site reactions: pain, erythema, pruritis and edema. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Mayne Pharma at 1-844-825-8500 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In two randomized, double-blind, vehicle-controlled trials, adult subjects with rosacea applied EPSOLAY (N = 488) or vehicle (N = 234) once daily for 12 weeks. The majority of subjects were Caucasian (93%) and female (73%) with a mean age of 51 years. Table 1 presents the most common adverse reactions occurring in ≥ 1% of subjects treated with EPSOLAY and more frequently than in subjects treated with vehicle. Table 1: Adverse Reactions Occurring in ≥ 1% of Subjects Treated with EPSOLAY and with Greater Frequency than Subjects Treated with Vehicle EPSOLAY N=488 Vehicle N=234 Application site pain 11 (2%) 2 (1%) Application site erythema 11 (2%) 2 ...

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.

6,807reports that mention this drug
6,803of those blame this drug, not another one the person was taking
20%of reports describe a serious outcome, such as a hospital stay (average for all drugs: 57%)
0.7%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.

Questions to ask your prescriber

  1. The most-reported problems in FDA's adverse event data are dry skin, acne, erythema. How would we recognize and handle those?
  2. There is no generic. Is there an older generic in the same class that works as well for my situation?
  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.)
