Methylene Blue 10 mg/mL Injection, USP 10 mL Single Dose Vial


Methylene Blue Injection, USP is a sterile solution of methylene blue in water for injection suitable for parenteral administration.


C16H18ClN3S                         MW = 319.86

Each mL of solution contains 10 mg of methylene blue.


Methylene blue is Phenothiazin-5-ium, 3,7-bis (dimethylamino)-, chloride, trihydrate. It will produce two opposite actions on hemoglobin. Low concentrations will convert methemoglobin to
hemoglobin. High concentrations convert the ferrous iron of reduced hemoglobin to ferric iron which results in the formation of methemoglobin.


Drug induced methemoglobinemia.


Intraspinal injection is contraindicated.


Methylene Blue should not be given by subcutaneous or intrathecal injection.


Methylene Blue must be injected intravenously very slowly over a period of several minutes to prevent local high concentration of the compound from producing additional methemoglobin. Do not exceed recommended dosage.

Adverse Reactions

Large intravenous doses of Methylene Blue produce nausea, abdominal and precordial pain, dizziness, headache, profuse sweating, mental confusion and the formation of methemoglobin.

Use in Pregnancy

Safety for use in pregnancy has not been established. Use of Methylene Blue in women of childbearing potential requires that anticipated benefits be weighed against possible hazards.

Dosage and Administration

0.1 to 0.2 mL per kilogram of body weight (0.045 to 0.09 mL per pound of body weight). Inject Methylene Blue intravenously very slowly over a period of several minutes.
