Fluid, Electrolyte, and Metabolic Abnormalities
Advise patients that they may experience symptoms from excessive fluid and/or electrolyte losses. The postural hypotension that sometimes occurs can usually be managed by getting up slowly. Potassium supplements and/or dietary measures may be needed to control or avoid hypokalemia [see Warnings and Precautions (5.1)].
Advise patients that furosemide may increase blood glucose levels and thereby affect urine glucose tests [see Warnings and Precautions (5.1)].
Photosensitivity
The skin of some patients may be more sensitive to the effects of sunlight while taking furosemide [see Adverse Reactions (6)].
Advise hypertensive patients to avoid medications that may increase blood pressure, including over-the-counter products for appetite suppression and cold symptoms [see Drug Interactions (7.1)].
