I am asking about taking Metoprolo Tarta 50 mg twice a day. I just looked up some side affects and I have made an appointment to have my eyes checked on Friday (today is Wednesday), because I have blurred vision (had cataract surgery in 2005 on both eyes), also when sleeping, and wake, feel shortness of breath and feel irregular heartbeat. Could there be a problem? Also Ramipril 10mg once a day, aspirin daily and Vitamin D2 1.25 mg twice a week, plus Niacin 500 mg once a day. I have never been a pill taker and I think that taking these pills make me more nervous than not taking anything for the blood pressure and cholesterol numbers.
