Read the Patient Information Leaflet if available from your pharmacist before you start taking furosemide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once or twice daily. It is best to avoid taking this medication within 4 hours of your bedtime to prevent having to get up to urinate.

The dosage is based on your medical condition, age, and response to treatment. Children's dosage is also based on weight. Older adults usually start with a lower dose to decrease the risk of side effects. Do not increase your dose or take it more often than directed.

Take this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time(s) of the day as directed. Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

Sucralfate, cholestyramine, and colestipol can decrease the absorption of furosemide. If you are taking any of these drugs, separate the timing of each dose from furosemide by at least 2 hours.

Tell your doctor if your condition does not get better or if it gets worse (for example, your blood pressure readings remain high or increase).
