Interactions between your drugs

Major

hydroCHLOROthiazide sodium biphosphate

Applies to: Hyzaar (hydrochlorothiazide / losartan) and Fleet EZ-Prep (sodium biphosphate / sodium phosphate)

The following interaction applies only to products containing sodium biphosphate that are used for bowel cleansing. It does not apply to products containing sodium biphosphate that are used for other, non-laxative related purposes.

Bowel cleansing with sodium biphosphate can cause kidney failure, in some cases up to several months after the procedure. Although it rarely occurs, the risk is increased in individuals receiving treatment with hydroCHLOROthiazide, especially if they are also elderly or frail. You may need a dose adjustment or special tests to safely use both medications. Combining these medications may also increase the risk of dehydration and electrolyte abnormalities. In severe cases, dehydration and electrolyte abnormalities can lead to irregular heart rhythm, seizures, and kidney problems. You should use sodium biphosphate exactly as prescribed by your doctor, and drink plenty of clear fluids before, during, and after the cleansing process to keep yourself hydrated. Your doctor may also recommend an electrolyte rehydration solution that you can use. Talk to your doctor if you have any concerns. 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.

losartan food

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.

Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. 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.
