Drug Interaction Report

Before you undergo any imaging procedure where metrizamide may be given by injection, let your doctor know if you are currently being treated with nebivolol. Injection of metrizamide can sometimes cause severe allergic reactions and low blood pressure, and the risk may be increased if you are also using nebivolol. In addition, treatment of the allergic reactions may be more difficult if medications like nebivolol are present in the body. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

If you are taking valsartan you should avoid potassium-containing salt substitutes or over-the-counter potassium supplements without first talking to your doctor. This can cause high levels of potassium in your blood. High levels of potassium can cause weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs. Call your doctor at once if you have any of these symptoms.
