Methylene Blue Injection 10mg is a medicine used to treat the symptoms of Acquired Methemoglobinemia. Methylene Blue may be used alone or with other medications.

Methylene Blue belongs to a class of drugs called Antidotes, Other. It is not known if Methylene Blue is safe and effective in children.

Methemoglobin is a form of hemoglobin (HEEM o glo bin). Hemoglobin is a substance in blood that carries oxygen and distributes it to your tissues and organs. However, methemoglobin is not a type of hemoglobin that is useful in carrying oxygen.

Methemoglobin normally exists in small amounts in the blood. However, when methemoglobin levels increase, the blood is less efficient in circulating oxygen. The resulting lack of oxygen throughout the body can cause symptoms such as pale or blue-colored skin.

Methemoglobinemia is a condition in which methemoglobin is present in high levels in the blood. Methemoglobinemia can occur when a person is exposed to certain drugs or chemicals such as nitrites.

Methylene Blue Injection 10mg is used to treat methemoglobinemia. Methylene Blue Injection works by converting methemoglobin to a more efficient type of hemoglobin to better carry oxygen throughout the body.

Methylene blue may also be used for purposes not listed in this medication guide.
