Precautions
Your doctor will check your or your child's progress closely while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly. Blood tests will also be needed to check for unwanted effects.
Severe hypotension (low blood pressure) may occur with this medicine. It could be life-threatening and requires immediate medical attention. Your doctor will measure your blood pressure and keep it from going too low while you are receiving this medicine.
This medicine may cause a rare, but serious blood problem called methemoglobinemia. Newborn babies and infants may be more likely to have this serious side effect. Your doctor will measure how much methemoglobin is in your blood and keep it from going too high while you are receiving this medicine.
