loss of vision
The worst side effect I have had of sprintec is loss of vision. I did not know what they meant when they asked me if I had loss of vision, so I said no. But I did feel that my eyes were blurrier. I got new contacts and glasses about a year into it, and then a year later my prescription changed again. Only then did I 100% realize that the sprintec was making me lose vision. (I had thought it meant blacking out).
Sprintec made me feel nauseous the two separate times I tried to take it instead of Mononessa
