Bumetanide tablets 1 mg – patient leaflet, side effects, dosage

1. What Bumetanide Tablets are and what they are used for

Bumetanide Tablets 1 mg contain the active substance bumetanide. Bumetanide is one of a group of medicines called diuretics (water tablets). They make the kidneys remove water from the body. Bumetanide Tablets are used to treat oedema, which is a build-up of fluid in the body. This may occur in many situations, for instance, with liver and kidney problems, or with heart failure (when the heart doesn’t pump efficiently).

2. What you need to know before you take Bumetanide Tablets

DO NOT take Bumetanide Tablets:

• If you are allergic to bumetanide, sulfonylureas or any of the other ingredients of Bumetanide Tablets (listed in section 6).

If you are elderly your doctor may reduce your dose. ■ If you are a diabetic or if you have ever had diabetes your doctor may ask for periodic checks on urine and blood glucose.
• If you suffer from any kidney disease, or are taking any drugs that may affect the kidneys, your doctor may closely monitor your body fluids and kidney functions.
• If you suffer from low blood pressure or are taking other medicines to treat high blood pressure. ■ If you are elderly and taking high doses of Bumetanide.
• If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking Bumetanide Tablets or other sulphonamides, e.g., Loop diuretics. ■ If you have problems with your liver.

Tell your doctor if any of these apply to you. He/she may want to monitor you or do some tests.
