My mother is 68 year old she is having serum cholesterole level 236 mg/dl. First of all she was having nausea and bp about 160/90 mg/dl after one day no was 110/72. My concern is that before this she had very normal blood pressure so should she continue her blood pressure medicine or not? Dr has prescribed bisoprolol fumarate daily 1 tablet 2.5mg. And ecosprin av 75 daily 1 tablet.
