Drug interactions between Hyzaar and omeprazole
Interactions between your drugs
Applies to: Hyzaar (hydrochlorothiazide / losartan) and omeprazole
Chronic use of drugs known as proton pump inhibitors including omeprazole can sometimes cause hypomagnesemia (low blood levels of magnesium), and the risk may be further increased when combined with other medications that also have this effect such as hydroCHLOROthiazide. In severe cases, hypomagnesemia can lead to irregular heart rhythm, palpitations, muscle spasm, tremor, and seizures. In children, abnormal heart rhythm may cause fatigue, upset stomach, dizziness, and lightheadedness. A dose adjustment or more frequent monitoring by the doctor may be required to safely use both medications. If you are using an over-the-counter proton pump inhibitor medication such as Prilosec OTC, Zegerid OTC or Prevacid 24 HR, you should follow the directions on the package carefully. Do not use the medication more frequently or for a longer period than recommended on the label unless otherwise prescribed by your doctor. 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.
Drug and food interactions
Applies to: Hyzaar (hydrochlorothiazide / losartan)
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.
