Bumetanide is used to treat water retention caused by heart failure, kidney or liver disease. Water retention may be noticed as swelling of the feet, ankles, lower leg and hands or shortness of breath. For this reason, it is commonly known as a "water pill".
Bumetanide is also used to treat high blood pressure.
Take Bumetanide exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
You may take Bumetanide with or without food. If you experience stomach discomfort with Bumetanide, take it with food. Try to take it at the same time each day.
You may need to pass urine more often while being treated with Bumetanide. Take Bumetanide early in the day to avoid waking up frequently at night to go to the toilet.
Bumetanide must be taken regularly for it to work well. Continue taking Bumetanide even when you feel better. Do not stop taking it unless instructed by your doctor.
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal schedule.
DO NOT double a dose under any circumstances.
If you often forget to take your medicine, let your doctor and pharmacist know.
Alert your doctor if you are unable to pass urine as Bumetanide may not be suitable for you.
Inform your doctor if you have:
- prostate problems or difficulty in passing urine
- liver disease
- kidney disease
- an allergy to sulfonamides (e.g. sulfa-containing antibiotic)
Let your doctor know if you are pregnant or breastfeeding.
If you are going for an operation, including minor surgery and dental work, inform your doctor or dentist that you are taking Bumetanide.
Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medicine regularly. He may also need to do routine blood tests while you are being treated with Bumetanide.
What lifestyle changes can I make to improve my blood pressure?
Regular exercise and eating a healthy diet will help lower your blood pressure and improve your overall health. Engage in physical activity (e.g. walking) at least 30 to 60 minutes on most days of the week. If you have not exercised for a long time, start with light exercises such as slow walks. Speak to your doctor about what type of exercise would be suitable for you. Follow a healthy diet plan by eating more fruits, vegetables, whole grains and low-fat dairy products and reduce your intake of foods high in saturated fat, cholesterol and sodium. Cutting down on deep-fried foods and using less salt when cooking can kick-start your healthy diet.
If you smoke, you should try to quit. Smoking is harmful to your blood pressure, heart and overall health. Speak to your doctor or pharmacist about ways to kick your smoking habit.
Bumetanide may cause muscle weakness, dizziness or drowsiness. If affected, do not drive or take part in any activity in which you need to be alert. Bumetanide may make you dizzy when you get up from a sitting or lying down position, especially if you are taking it for the first time. This is normal and should go away as you get used to the medicine. It will help if you get up slowly.
You may need to pass urine more often while you are being treated with Bumetanide. As your body adjusts to the medicine, this urination effect should also decrease.
Other side effects include any of the following: muscle cramps, headache, nausea, abdominal pain and rashes.
Some side effects may be serious, although they are not common. Alert your doctor quickly if you experience:
- hearing problems such as loss of hearing, ringing or buzzing sounds in the ear
- fainting or mental confusion
Inform your doctor if any of these side effects do not go away or are severe, or if you experience other side effects.
Inform your doctor and pharmacist if you are taking any of these medicines:
- medicines for heart disease or high blood pressure e.g. digoxin, enalapril
