Bumex is used to lower the amount of excess salt and water in your body by increasing the output of urine. It is prescribed in the treatment of edema, or fluid retention, associated with congestive heart failure and liver or kidney disease. It is also occasionally prescribed, along with other drugs, to treat high blood pressure.
Most important fact about Bumetanide
Bumex is a powerful drug. If taken in excessive amounts, it can severely decrease the levels of water and minerals, especially potassium, your body needs to function. Therefore, your doctor should monitor your dose carefully.
How should you take Bumetanide?
Bumex can increase the frequency of urination and may cause loss of sleep if taken at night. Therefore, if you are taking a single dose of Bumex daily, it should be taken in the morning after breakfast. If you take more than one dose a day, take the last dose no later than 6:00 PM.
--If you miss a dose...
Take the forgotten dose as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time.
--Storage instructions...
Store at room temperature.
What side effects may occur?

Special warnings about Bumetanide
If you are allergic to sulfur-containing drugs such as sulfonamides (antibacterial drugs), check with your doctor before taking Bumex.
Bumex can decrease the number of platelets in your blood. Your doctor should monitor your blood status regularly.
Bumex can cause a loss of potassium from the body. Your doctor may recommend foods or fluids high in potassium or may want you to take a potassium supplement to help prevent this. Follow your doctor's recommendation carefully.
While taking Bumetanide you may feel dizzy or light-headed or actually faint when getting up from a lying or sitting position. If getting up slowly does not help or if this problem continues, notify your doctor.
Possible food and drug interactions when taking Bumetanide
If Bumex is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining Bumex with the following:
Blood pressure medications such as Vasotec and Tenormin
Indomethacin (Indocin) and other nonsteroidal anti-inflammatory drugs
Probenecid (Benemid)
The combination of Bumex and certain antibiotics or cisplatin (Platinol) may increase the risk of hearing loss.
Because Bumex can lower potassium levels, the combination of Bumex and digitalis or digoxin (Lanoxin) may increase the risk of changes in heartbeat.
The combination of Bumex and lithium (Lithonate) may increase the levels of lithium in the body, causing it to become poisonous.
Special information if you are pregnant or breastfeeding
The effects of Bumex during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, inform your doctor immediately. It is not known if Bumetanide appears in breast milk. Your doctor may advise you to discontinue breastfeeding your baby until your treatment with Bumex is finished.
