Do treatments in research have any side effects?
There is a risk of side effects with any drug.
During their development, all new drugs are monitored very closely for any side effects or safety concerns. The earliest phase of testing takes place in laboratories and it is only after a potential treatment is thought to be safe that it is tested in people. The first round of clinical trials is only designed to test safety. To start with a small number of patients are given a very small dose of the test drug.
The dose is gradually increased as more patients join the trial, with all participants being very closely monitored for any problems. This monitoring continues right through the clinical trial process until a treatment is licensed and made available. Even after a drug is put on the market, any reaction or symptom a patient has that could possibly be drug related has to be recorded and reported.
