Humira and Neurotoxicity - a phase IV clinical study of FDA data

Summary:

Neurotoxicity is reported as a side effect among people who take Humira (adalimumab), especially for people who are female, 30-39 old, have been taking the drug for 1 - 6 months also take Methotrexate, and have Inflammatory bowel disease.

The phase IV clinical study analyzes which people have Neurotoxicity when taking Humira. It is created by eHealthMe based on reports of 758,421 people who have side effects when taking Humira from the FDA, and is updated regularly.
