RhabdomyolysisEn Español (Spanish Version)
Rhabdomyolysis occurs when skeletal muscles are damaged and release myoglobin into the bloodstream. Myoglobin is an iron-containing pigment that can cause severe damage to the kidneys.
Rhabdomyolysis results from any condition that causes significant muscle damage. These include:
A risk factor is something that increases your chance of getting a disease or condition. Factors that may increase the risk of muscle damage include:
- Extreme exertion, such as running a marathon
- Heat stroke
- Alcohol or drug abuse
- Uncontrolled seizure disorder
The most common symptoms include:
- Dark colored (brown or red) urine
- Muscle pain
- Muscle weakness
Other symptoms include:
- Muscle swelling
- Back pain
In severe cases, rhabdomyolysis may result in:
- Kidney damage or failure due to blocked arterial blood flow
- Multi-organ failure
- Abnormal heartbeat ( arrhythmia )

The doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include:
- Urine tests
- Blood tests
- Muscle testing ( electromyography )
Treatment may include:
Giving large amounts of fluid is the main treatment. Fluids are usually given directly into a vein by an IV. Hydration helps to quickly flush myoglobin out of the kidneys, in order to restore their function.
Medication may include:
- Diuretics—to help flush out the kidneys
- Bicarbonate—to minimize myoglobin's toxic effects
Dialysis is a procedure that uses an artificial kidney machine to filter blood. The clean blood is then returned to your body.
