Methotrexate and Trigeminal neuralgia - a phase IV clinical study of FDA data

Summary:

Trigeminal neuralgia is reported as a side effect among people who take Methotrexate (methotrexate sodium), especially for people who are female, 50-59 old, have been taking the drug for 1 - 6 months also take Humira, and have Ankylosing spondylitis.

The phase IV clinical study analyzes which people have Trigeminal neuralgia when taking Methotrexate. It is created by eHealthMe based on reports of 599,650 people who have side effects when taking Methotrexate from the FDA, and is updated regularly.
