Common questions
Which has more reported side effects, Ramipril or Enalapril?
Ramipril has 123,136 FAERS reports and Enalapril 55,275. More reports does not mean more dangerous: volume follows how widely and how long a drug has been used, prescription vs over-the-counter status, and publicity. The seriousness share (93% vs 84%) is a better like-for-like signal of the kind of problems reported.
Which side effects do Ramipril and Enalapril share?
They share no strong flagged signal after artifacts and lab terms are removed.
Is Ramipril or Enalapril safer?
FAERS cannot answer that: it has no denominator and no comparator. Use this page to see which risks are already on each label and which signals are unlabeled, then check the prescribing information and your clinician for your situation.
