Why this happens
Both drugs can affect how the kidneys work. When used together, they may increase the sensitivity of the immune system, making a severe skin rash or allergic reaction more likely. Additionally, they can have an additive effect on lowering blood pressure and kidney filtration.
What you should do
You can usually take these together, but you must be monitored by your doctor. Seek immediate medical help if you develop a skin rash, hives, or swelling of the face. Your doctor may want to perform regular blood tests to check your kidney function and monitor your blood pressure closely.
