Fluid buildup is a common problem in people with heart failure (HF) or chronic kidney disease (CKD). These conditions can cause your body to hold on to extra fluid, which can make both conditions worse over time.
Fluid buildup is usually managed by taking oral diuretics. Despite this, sometimes fluid can continue to build up. When that happens, intravenous (IV) diuretics are often needed, typically requiring hospital admission.
FUROSCIX is a prescription medicine used to treat fluid buildup, which can cause congestion or swelling (also known as edema), in adult patients with chronic heart failure or chronic kidney disease.
FUROSCIX should be replaced with oral diuretics as directed by a healthcare provider. Follow the instructions provided by your physician when taking FUROSCIX.
Dehydration: FUROSCIX can cause you to lose excess water and electrolytes. Symptoms of excess water and electrolyte loss include dry mouth, increased thirst, muscle pains or cramps, decreased urine output or urine more yellow than normal, headache, dry skin, nausea or vomiting. Your healthcare provider may check your electrolytes while receiving FUROSCIX.
Low Blood Pressure: FUROSCIX may cause your blood pressure to decrease temporarily. You may feel lightheaded or dizzy, particularly when you stand up. Getting up slowly may help.
High Blood Sugar: If you have diabetes mellitus, FUROSCIX may increase blood glucose levels.
Loss of Hearing: FUROSCIX can cause ringing in your ears. Tell your healthcare provider if you have trouble hearing while taking FUROSCIX.
Incomplete Dosing: When using the FUROSCIX ReadyFlow, if the viewing window does not turn completely yellow, or if you lift the FUROSCIX ReadyFlow off your skin too early, you may not receive a full dose. This could cause the medicine to not work as well as it should. If this happens call your healthcare provider for more instructions. Do not use another FUROSCIX ReadyFlow unless instructed to do so by your healthcare provider.
Your skin may be more sensitive to sunlight while taking FUROSCIX.
The most common side effects with FUROSCIX are administration site and skin reactions such as bruising, redness, swelling and administration site pain.
Call your healthcare provider for medical advice about side effects. You may report side effects to MannKind at 1-877-323-8505 or to the FDA at 1-800-FDA-1088.
