Contact your doctor or go to the emergency room immediately if you experience any of the following symptoms after a blood transfusion and Lasix administration:
Severe allergic reaction: This includes difficulty breathing, swelling of the face, lips, or tongue, hives, or a rapid heartbeat. These are serious signs requiring immediate attention.
Signs of fluid overload: Rapid weight gain (more than 2 pounds in a day), shortness of breath, swelling in your legs or ankles, persistent cough, or chest pain may indicate fluid retention despite Lasix. These warrant urgent medical evaluation.
Low blood pressure (hypotension): Dizziness, lightheadedness, fainting, or feeling weak could indicate dangerously low blood pressure, needing prompt medical care.
High potassium levels (hyperkalemia): Muscle weakness, numbness, tingling, slow heart rate, or palpitations can be signs of dangerously high potassium levels, a potentially life-threatening condition.
Kidney Function Changes
Monitor your urine output closely. Significant reduction or absence of urine production should prompt immediate medical attention, as this could indicate kidney problems.
Other Serious Symptoms
Report any unusual bleeding, unexplained bruising, fever, chills, or persistent nausea and vomiting. These may indicate complications from the transfusion or medication.
