This patient support community is for discussions relating to Dysautonomia (Autonomic Dysfunction) including: Postural orthostatic tachycardia syndrome (POTS), neurocardiogenic syncope, mitral valve prolapse dysautonomia, pure autonomic failure, autonomic instability and others.
The most common side effect in my experience is severe headache. I just started Florinef again a couple of weeks ago, and the headache is finally subsiding. Other possible side effects I am aware of include: weight changes, appetite changes, upset stomach, etc.
I hope that information is helpful, perhaps someone else in our community will be able to offer you more information.
