Research and Clinical Use of Methylthioninium Chloride (methylene blue)

Methylthioninium chloride, also known as methylene blue, is a substance that has long been used in medicine. Scientists are now intensely studying it as it may help in treating several serious diseases.

What is methylene blue used for?

• Treatment of methemoglobinemia — a condition where blood cannot properly carry oxygen. This drug helps quickly restore normal blood function.
• In critical care, it is being tested in patients with severe septic shock or complications after heart surgeries.
• Neurodegenerative diseases, such as Alzheimer's disease – studies show it may slow the deterioration of memory and other functions.
• Treatment of infections – in combination with light, it can destroy bacteria and viruses, including the SARS-CoV-2 virus.

What do studies say?

• In patients with septic shock, methylene blue shortens the time they need medications to support blood pressure.
• In Alzheimer's disease, studies suggest improvement in memory and thinking.
• Laboratory tests confirm the destruction of bacteria and viruses.

Safety and Side Effects

• The drug is well absorbed and utilized by the body.
• Occasionally, it may cause a slight increase in blood pressure or change the color of urine to blue-green – it is not dangerous.
• If you are taking certain depression medications, there may be a risk of serotonin syndrome, so consult with a doctor.
