Prescription drug side effects are now your most likely source of death, disability, or injury.

Experts estimate that only 1–10% of serious adverse events (those causing hospitalization, disability, or death) are ever reported. Not to mention the millions of medically mild adverse drug events that occur each year — ones that compromise your concentration, functioning, judgment, and ability to care.

Making medicines safer for all of us

RxISK is a free, independent website where you can research prescription drugs and report a drug side effect — identifying problems and possible solutions when it might still be possible to intervene and find a solution.

Free resources

RxISK offers tools and access to data on prescription drugs and drug side effects you can’t get anywhere else — including a searchable database of almost 6 million reports filed with the FDA, Health Canada, and RxISK.

Free RxISK report

Our secure reporting process allows you to identify which drugs you are taking and comment on their effects on your health and life. The resulting RxISK Report provides you with your RxISK Score indicating how likely it is that you are experiencing a drug side effect.

This structured tool can help you articulate what is happening to you and determine whether your doctor is listening.

If something is going wrong with your treatment, bringing a RxISK Report to your doctor as early as possible may be the difference between successful treatment and long-term disability or death.

No one knows a drug’s side effects like the person taking it

You and your doctor may have been told there is no evidence linking the treatment you are on to the problems you are experiencing. This is because most data on prescription drugs is owned by the multinational pharmaceutical companies who run almost all clinical drug trials (60% of which are never reported). They simply are not sharing data that may affect their bottom line.

If you think there is a problem, you are probably right.
