I have had headaches, chest pain, constipation, dry mouth ( so much so it interrupts my sleep...in fact I am writing this at 3;00 am so frustrated), eyes, etc. it seems just after taking rosuvastatin calcium 20 mg (started just five days ago). Are these normal side affects of taking rosuvastation calcium 20 mg. If so I think I should tell my doctor to put me on something else.
