Clonidine and Microangiopathy - a phase IV clinical study of FDA data

Summary:

Microangiopathy is reported as a side effect among people who take Clonidine (clonidine), especially for people who are female, 60+ old, have been taking the drug for 1 - 6 months also take Cozaar, and have Cataplexy.

The phase IV clinical study analyzes which people have Microangiopathy when taking Clonidine. It is created by eHealthMe based on reports of 63,883 people who have side effects when taking Clonidine from the FDA, and is updated regularly.

What is Clonidine?

Clonidine has active ingredients of clonidine. It is often used in high blood pressure. eHealthMe is studying from 65,645 Clonidine users. Check the latest studies of Clonidine.

What is Microangiopathy?

Microangiopathy (disease of the capillaries (very small blood vessels), in which the capillary walls become so thick and weak that they bleed, leak protein) is found to be associated with 234 drugs and 332 conditions by eHealthMe. Check the latest studies of Microangiopathy.
