Eliquis and Red cell distribution width increased - a phase IV clinical study of FDA data

Summary:

Red cell distribution width increased is reported as a side effect among people who take Eliquis (apixaban), especially for people who are female, 60+ old, have been taking the drug for 1 - 2 years also take Stelara, and have Ulcerative colitis.

The phase IV clinical study analyzes which people have Red cell distribution width increased when taking Eliquis. It is created by eHealthMe based on reports of 189,425 people who have side effects when taking Eliquis from the FDA, and is updated regularly.
