Report your side effects

Together we can get this
taken seriously.

  • Report the drug, what happened, and when.
  • No diagnosis needed. Your experience counts.
  • Enough reports, and the system must react.

Nine in ten side effects are never reported.

21 of 240. Each dot is one side effect. The bright ones reached a regulator (the government office that watches medicines). FDA MHRA
How it works

What happens when you submit

Most people never report. They think the form goes nowhere.

1

It reaches your regulator

  • The regulator in your own country
  • A trained person reads it
2

It joins the global database

  • Sent on to WHO's VigiBase in Uppsala
  • Reports on every medicine are collected there
3

It gets checked for patterns

  • Experts ask: does this happen more often than chance?
  • They can only check reports that exist
4

It gets taken seriously

  • A strong enough pattern forces a review
  • The FDA did this for finasteride in 2011
It still counts
  • “I can’t prove it was the drug.”
  • “It was years ago.”
  • “My doctor disagreed.”
  • “Someone else has already reported it.”

Do it anyway.

None of these stops you. Every form on this page takes suspected side effects, straight from patients, no matter how long ago.

Report your side effects
Watch it done first

See the whole form before you start

Four films show a whole report being filled in, with the waiting cut out. No sound, so you can watch anywhere.

These are the UK and US forms. Most countries ask the same things in the same order: the medicine, the dates, and what happened. If your country is not here, these still show you what to expect.

The details on screen are made up. Write your own, in your own words. That is the part a real person reads.

PFS & PSSD registry

Do both: report it, then join the registry

Your regulator counts the side effect. Our registry counts the person. It shows researchers, journalists and doctors how many of you there are.

Your report is the evidence
