Brief Answer: Alternatives to Lisinopril and Losartan.... Detailed Answer: Hi, Losartan use is associated with increased levels of potassium as well as potassium-sparing diuretics. When I prescribe Losartan to my patients, I usually ask them to check electrolytes levels every 3 months. I also avoid combination of Losartan with potassium-sparing diuretics to prevent hyperkalemia. Lisinopril also causes the kidney to retain potassium, increasing the levels of potassium in the blood. Both of them do not contain diuretics unless you use a combination of such drugs with diuretics (commonly with hydrochlorothiazide). Furthermore, to my knowledge, no study has concluded that these drugs are not appropriate for African Americans unless individual contraindications. Emergen C you are taking contains also potassium. If you are using such HBP medicines and Emergen C simultaneously, this combination would cause problems with hyperkalemia. I suggest to discuss with your doctor about adding diuretics like hydrochlorothiazide or furosemide according to your cardiac tests and blood pressure. I also suggest to measure the levels of electrolytes in the blood and to re-consider the use of Emergen C. Hope it helps! If you have other queries, do not hesitate to write me back! Dr.Albana
