Effexor and Brain hypoxia - a phase IV clinical study of FDA data

Summary:

Brain hypoxia is reported as a side effect among people who take Effexor (venlafaxine hydrochloride), especially for people who are female, 60+ old, also take Celexa, and have Acute myeloid leukaemia.

The phase IV clinical study analyzes which people have Brain hypoxia when taking Effexor. It is created by eHealthMe based on reports of 92,291 people who have side effects when taking Effexor from the FDA, and is updated regularly.

What is Effexor?

Effexor has active ingredients of venlafaxine hydrochloride. It is often used in depression. eHealthMe is studying from 99,496 Effexor users. Check the latest studies of Effexor.
