Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, especially if you are taking medicines for:

• high blood pressure (hypertension) or angina (e.g., calcium channel blockers, angiotensin-converting enzyme inhibitors (ACEIs), and angiotensin receptor antagonists (ARAs)),
• diuretics (medicines that increase urine production),
• non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin,
• certain medicines for mental disorders (those containing lithium),
• other medicines that may dehydrate you or alter the levels of salts (potassium, sodium, phosphate, or water) in your body (electrolyte balance),
• medicines that alter heart rhythm,
• medicines that contain parathyroid hormone,
• medicines taken orally, such as oral contraceptives, antiepileptics, antidiabetics, or antibiotics, because Fosfosoda may reduce or even cancel the availability of these medicines in the body, making their effect smaller or even canceling their effect.
