Bumex (also called Burinex in Canada) is a potent water pill, known as a loop diuretic. Your doctor may prescribe Bumex to reduce and manage excess fluid build-up in your body due to congestive heart failure (CHF) and kidney or liver disease. This extra fluid that accumulates from your heart not being able to pump blood around your body as it should be, can cause swelling in your arms, legs, feet, lungs, and other parts of your body that can make you short of breath.
Your doctor will monitor you as Bumex or generic Bumetanide can cause you to lose too much water and also deplete your electrolytes, which are nutrients your body needs to function properly. The generic alternative is not manufactured by the company that makes the brand product.
When taken orally as directed, loop diuretics such as Bumex obstruct the transport of salt and water across particular cells in your kidneys located in a structure known as the loop of Henle that is responsible for reabsorbing them. By blocking that action, Bumex makes your kidneys pass more fluid out of your body through urination. Bumex also helps lower high blood pressure to reduce the risk of a heart attack or stroke.
Heart failure means your heart is not pumping as strong as it used to so the blood flow is slower through your heart and the rest of your body, resulting in the pressure in your heart to increase. In response to not being able to pump a sufficient supply of oxygen and nutrients for your body’s needs, the chambers of your heart stretch to try and retain more blood to send out or by becoming stiff and thickened. This only works for a short time before the muscle walls of your heart weaken and cannot pump properly causing your kidneys to retain fluid and sodium.
Ask your doctor about any possible risks of taking Bumex while you are pregnant, may become pregnant, or are breast feeding. Discuss other medical conditions or allergies with your doctor and list any current OTC or Rx drugs you take or use, including herbal remedies and dietary or vitamin supplements to determine if Bumex is the right medication for you.
The effects of Bumex start in about 1 hour and can last up to 6 hours so you may need to adjust your daily schedule to prevent having to go to the bathroom at an inopportune time or location. Until you know how Bumex will affect you, do not drive, operate machinery, or attempt any task that requires your full attention. Do not share any medications with others and store them safely out of children’s reach.
