Quick answers
Why am I urinating more?
Furosemide is a diuretic, often called a water pill. It helps the kidneys remove salt and water to treat fluid buildup and sometimes high blood pressure.
Should I drink more water or take potassium?
Ask for your personal fluid, salt and potassium plan. Do not start supplements or change a fluid restriction without checking with your care team.
Can I skip it when swelling improves?
Follow your prescription. Some people use daily schedules; others have specific days or clinician-directed adjustment plans. Feeling better is not a reason to change it yourself.

What if I miss a dose?
Take it when remembered unless the next dose is almost due; then skip it. Do not double up. Ask your pharmacist to help you follow the schedule while planning around frequent urination. MedlinePlus
Which symptoms should I report?
Contact your clinician for unusual thirst, muscle cramps, marked weakness, dizziness or much less urine. Report vomiting or diarrhea that prevents normal intake. Fainting, confusion or a racing or irregular heartbeat needs urgent assessment. New hearing problems also need prompt attention. Furosemide label, precautions and adverse reactions
What tests or interactions matter?
Keep ordered kidney-function and electrolyte tests, including potassium. Share all medicines, especially NSAIDs such as ibuprofen, lithium, other blood-pressure medicines and sucralfate. Follow your clinician's monitoring plan; there is no single safe fluid or supplement recommendation for everyone. Furosemide label, laboratory tests and interactions
Keep your instructions together
Bring your medication list and any written fluid or weight-monitoring plan when you ask Fairview for help. Prescription services are handled through the pharmacy, not the OTC shop. This is general education, not an instruction to change your dose.
