Glivec and Brain herniation - a phase IV clinical study of FDA data


We study 17,769 people who have side effects when taking Glivec. Brain herniation is found, especially among people who are female, 60+ old, have been taking the drug for 5 - 10 years, also take Diclofenac sodium and have Chronic myeloid leukaemia.

The phase IV clinical study analyzes which people take Glivec and have Brain herniation. It is created by eHealthMe based on reports from the FDA, and is updated regularly. You may use the study as a second opinion to make health care decisions.

Phase IV trials are used to detect adverse drug outcomes and monitor drug effectiveness in the real world. With medical big data and AI algorithms, eHealthMe is running millions of phase IV trials and makes the results available to the public. Our original studies have been referenced on 700+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature.

What is Glivec?

Glivec has active ingredients of imatinib mesylate. Currently, eHealthMe is studying from 17,777 Glivec users.

What is Brain herniation?

Brain herniation (brain herniation is a potentially deadly side effect of very high intracranial pressure that occurs when a part of the brain is squeezed across structures within the skull) is found to be associated with 1,365 drugs and 933 conditions by eHealthMe. Currently, we are studying 3,579 people who have Brain herniation.
