Allergic-like reactions and methemoglobinemia have been documented after the use of methylene blue dye in chromopertubation. [9] These reported symptoms vary from blue discoloration of body fluids to anaphylactic shock. [10] Methemoglobinemia is a blood disorder that can potentially result in various levels of cyanosis. [11]
Methylene blue has been described as "the first fully synthetic drug used in medicine." Methylene blue was first prepared in 1876 by German chemist Heinrich Caro.

Methylene blue is given as a 1% solution (10 mg/ml) 1 to 2 mg/kg administered intravenously slowly over five minutes. Although the response is usually rapid, the dose may be repeated in one hour if the level of methemoglobin is still high one hour after the initial infusion. Methylene blue inhibits monoamine oxidase, and serotonin toxicity can ...
Tuboplasty refers to a number of surgical operations that attempt to restore patency and functioning of the fallopian tube(s) so that a pregnancy could be achieved. As tubal infertility is a common cause of infertility , tuboplasties were commonly performed prior to the development of effective in vitro fertilization (IVF).

The most effective treatment for severe (grade III–IV) encephalopathy is an intravenous solution of methylene blue, which appears to shorten the duration of encephalopathy; the exact mechanism of action of methylene blue is unclear. In some cases, methylene blue may be used as a prophylaxis before further doses of ifosfamide are administered.
