What are the side effects of mannitol IV?


Mannitol IV may cause some minor side effects, including chills, dizziness, headache, nausea and vomiting, rash, and runny nose. Mannitol can change the amount of fluid in your body, which can result in dehydration, fluid retention, electrolyte loss, fluid and electrolyte imbalance, increased urination, pulmonary congestion, and retaining urine.

Some additional side effects may include acidosis (too much acid in your body fluids), angina-like chest pains, arm pain, blurred vision, convulsions, dry mouth, fever, low blood pressure, skin problems, fast heartbeat, thirst, and swelling of a vein due to a blood clot.

Some of these symptoms may not actually be side effects of the mannitol but may indicate changes your kidney condition, so be sure to talk to your doctor.

Also let your doctor know if you have swelling, pain, or skin changes at the injection site. If you have any signs of a severe allergic reaction, such as difficulty breathing, hives, or swelling in your face, mouth, throat, or tongue, call 911 to get emergency medical help right away.
