Concerns about specific medicines
Medicines have to pass many different tests before they are licensed for use outside of clinical trials.
If a medicine appears to be safe and seems to offer important advantages to patients, it will be used even though some questions remain about just how safe it is in the long run.
Trials are limited in size and duration, and it often takes many years or even decades for scientists and doctors to gather enough information to find out about rare and long term side effects.
