Your routine urine test is completely normal and free of protein. Often, bubbles in urine can simply be due to a fast urine stream or mild dehydration. Neither your cholesterol medication, Rozucor (rosuvastatin), nor your blood pressure medication, Covance (losartan), are typical causes of bubbly urine. Since your tests are clear, there is no immediate cause for concern. Just try to stay well-hydrated. If the bubbles persist or you develop new symptoms, please check back in with your doctor for peace of mind.
