Rifampicin

Instead of targeting DNA replication, rifampin blocks transcription by preventing the formation of messenger RNA.

No messenger RNA means no protein production, which ultimately leads to cell death, so this one is bactericidal.

Rifampin is usually reserved for serious infections, things like tuberculosis and leprosy, both caused by acid-fast mycoplasmas, and is often given in combination with drugs like isoniazid.

There's one side effect that always shows up on exams.

It turns body fluids a bright orange-red color, so if you ever see that, you should immediately think rifampin.

For methicillin-resistant staphylococci, we use vancomycin, adjusting the dose to target levels, or daptomycin in high doses.

In prosthetic valve staphylococcal endocarditis, we add rifampicin for the full course and gentamicin for the first two weeks.

Rifampicin should be started a few days after the other antibiotics once the bacteremia is controlled to reduce the risk of resistance.

For Enterococcus faecalis, the preferred regimen is ampicillin combined with ceftriaxone for six weeks.

This combination works as well as ampicillin with gentamicin but is much safer for the kidneys, which is important because many of these patients are elderly.

You're basically turning on certain switches in your body that turn on inflammation.

Um, so for example, if your level of pain and fatigue and brain fog, let's say, is at a five out of 10, and now I'm giving you antibiotics, especially biofilm persister drugs, right, like the Dapsone combination therapy, which is targeting these biofilm persister, which are known, by the way, according to John Hopkins, these are the forms that drive most of the inflammation in your body, right? So now let's say I'm treating you with this, um, but let's say in the past, you just took Zithromax for five days, and you went, "Wow, I feel so much better." But now I'm giving you Rifampin, Zithromax, Dapsone, right, with a little minocycline with methylene blue.

I'm adding persister drugs, and you go, "Oh my God, my fatigue is so much worse.

My brain fog is worse.
