168 views

Medications that can cause a high BUN (Blood Urea Nitrogen)/creatinine ratio include certain diuretics and corticosteroids. Diuretics, often prescribed for high blood pressure, can lead to dehydration, thereby increasing BUN levels more than creatinine levels. Corticosteroids, used for a variety of conditions including inflammation and autoimmune diseases, may also elevate the BUN/creatinine ratio. Always consult with a healthcare professional before making any changes to your medication regimen.
