Hydrea and Neuralgia - a phase IV clinical study of FDA data

Summary:

Neuralgia is reported as a side effect among people who take Hydrea (hydroxyurea), especially for people who are male, 60+ old, also take Clopidogrel, and have Primary myelofibrosis.

The phase IV clinical study analyzes which people have Neuralgia when taking Hydrea. It is created by eHealthMe based on reports of 8,922 people who have side effects when taking Hydrea from the FDA, and is updated regularly.

What is Hydrea?

Hydrea has active ingredients of hydroxyurea. It is often used in polycythemia vera. eHealthMe is studying from 9,083 Hydrea users. Check the latest studies of Hydrea.

What is Neuralgia?

Neuralgia (pain in one or more nerves) is found to be associated with 1,388 drugs and 1,786 conditions by eHealthMe. Check the latest studies of Neuralgia.
