Yesterday I started taking meclizine 2 - 25 mg every 6 hours (have taken 4 doses since) perscribed from my doctor for sudden onset of intense vertigo starting on thursday. I am sensitive to meds, so I didn't start taking it until yesterday (Saturday). I just noticed that I am bleeding from my uterus - I haven't bleed in 6 years and am menopausal. Concerned.... did the Meclizine cause this bleeding? Should I stop taking it? Is the vertigo and the bleeding related - and should I be concerned and seek immediate help? Thank you for your help, Victoria
