It is very important that your doctor check your progress closely while receiving this medicine to see if it is working properly. Blood tests may be needed to check for any unwanted effects.

This medicine may cause a rare, but serious blood problem called methemoglobinemia. The risk may be increased in children younger than 6 months of age, elderly patients, or patients with certain inborn defects. It is more likely to occur in patients receiving too much of the medicine, but can also occur with small amounts. Check with your doctor right away if you have pale, gray, or blue-colored skin, lips, or nails, confusion, headache, lightheadedness, fast heartbeat, or unusual tiredness or weakness.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
