The Story of the Blue Pee

First, the story. When wounded arrive, Col. Potter asks Pitts, the marine leader to help out. After surgery is done, Charles and B.J. talk about how tired they are while Urbancic, the bowling pro, is there with them. They offer to give each other a “pep pill” so they can make it through the rest of the bowling match. Urbancic asks for a pep pill too. The two “reluctantly” agree to give him one, warning him about how strong the pills are.

Klinger scolds them for helping the competition but they tell Klinger, laughing, that those pills will do nothing for pep but will only turn a person’s pee blue. The pills are methylene blue. Later, Urbancic runs to BJ and Charles and tells them, in a panic, that he is “turning blue inside.”

They “diagnose” him and tell him that he must, at all costs, avoid bending over for any reason and it would then pass in a little while. Since Urbancic can’t bend over, he can’t bowl very well. With the help of Urbancic attempting to bowl without bending over, and MASH’s own ringer, Margaret, the unit finally achieves victory over the marines.

The Blue Pee Drug in MASH Is Real

Methylthioninium chloride, commonly called methylene blue, is used as a dye and as a medication. As a medication, it is mainly used to treat methemoglobinemia, a rare blood disorder that affects how red blood cells deliver oxygen throughout your body. In the past, it was used to treat cyanide poisoning and urinary tract infections, but it is not used for either today.

Methylene blue is also used as a dye for various reasons in medical treatment. It is not usually ingested but is injected into a vein. When ingested, it can cause headache, nausea, and vomiting. And, yes, it can cause urine to change colors. When interacting with the yellow color of pee, it turns the pee a blue-green or blue color. It also causes fecal discoloration.

In fact, methylene blue has been used as a placebo for this very reason. Doctors would give their patients a methylene blue pill and tell them that when their urine turned blue, it was a sign the medication was working. As a placebo in a controlled clinical trial this would not work and it makes it difficult to study the compound for medical uses, as those subjects getting the true blue in the study will know they are not just getting a sugar pill!

It may have been knowledge of this use of methylene blue that caused the writers to use it in the MASH episode.
