My mother is 79 years old has had 2 heart valve replacements, angina, high cholestrol, has a pacemaker, and is on rampiril, plavix, carvedoil, and crestor and after taking her pills she gets sick, lightheaded, naseau, with headache and the room spins. Should i space out her meds, she takes the crestor at night but during day she feels horrible and is bedridden after she takes her pills for several hours.
