Procysbi and Dyspnea - a phase IV clinical study of FDA data

Summary:

Dyspnea is reported as a side effect among people who take Procysbi (cysteamine bitartrate), especially for people who are male, 20-29 old, also take Melatonin, and have Cystinosis.

The phase IV clinical study analyzes which people have Dyspnea when taking Procysbi. It is created by eHealthMe based on reports of 998 people who have side effects when taking Procysbi from the FDA, and is updated regularly.
