Typical dosage for Methylene Blue

The typical dose is 1 mg/kg of body weight injected through the veins (IV) over 5 to 30 minutes.

If your methemoglobin level stays above 30%, or you still have methemoglobinemia symptoms (e.g., shortness of breath, fast heart rate, weakness), your care team will consider repeating the dose after an hour, as long as you don't have kidney problems.
