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.

This section explores some of the concerns there have been about specific medicines used in the care of diabetes. Some have ultimately been shown to be unfounded, others are still being explored. In cases such as rosiglitazone, the concerns resulted in the medication being removed from the market.
