Part 1Record first, judge later
Study staff write down health events as they happen. Whether the event is related to the study product is assessed separately and often cannot be known for one person.
Part 2Serious versus mild
Events that lead to hospital stays or are life-threatening are labeled serious and go to sponsors, boards and regulators on a shorter clock.
Part 3After approval
Once a product is on the market, the FDA’s MedWatch program accepts reports from health professionals and the public. These reports are signals to look into, not proof of cause.
Part 4Talk to a professional
If you think you are having a reaction to anything, contact a doctor or pharmacist. Information websites like this one cannot assess symptoms.
