Drug Interactions between losartan and Nexium IV

If you are taking losartan 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.

In some patients grapefruits and grapefruit juice may decrease the efficacy of losartan. Grapefruits and grapefruit juice should be avoided if an interaction is suspected. Orange juice is not expected to interact.

Food may interfere with the absorption of esomeprazole. Esomeprazole should be taken at least one hour before meals and at the same time every day. When esomeprazole is given to patients receiving continuous enteral nutrition (tube feedings), the tube feeding should be interrupted for at least 1 hour before and 1 hour after the dose of esomeprazole. This will make it easier for your body to absorb the medication. 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.
