Long Covid and Doxycycline: Inflammation Theory

Thanks for the question. I have been taking 100 mg of doxy every morning for about a month now. I was taking it prior to a month ago, very sparingly because I did not have many tablets left. After seeing my doctor and explaining that I also have Lyme Disease and Alpha Gal Allergy from ticks because I live in a very wooded area, I need whatever protection I can get to ward off another tick borne illness. I also have rosacea and Doxy 100 mg daily is the drug of choice. However I wondered if it might just help rid me of constant (bigeminy) heart palpitations. So far, I have after a month, seen on my Kardia device that I have times when there are NO PVCS or SVES and I am in "Normal Sinus Rythym". I have not seen that reading ONCE since last December until after taking the Doxy. The erratic heartbeat is far from gone, but for the first time in over six months, there is finally some improvement!

Wow! That’s great! 😃 thank you for responding!

I too have PVC’s and would LOVE for them to go away!
It seems they do disappear whenever I’m taking some random antibiotics for Covid gut. But then return within a couple of weeks after use, along with my other symptoms of bloating, full body swelling, GI pain, brain fog, and feeling hypoglycemic but not (weak, shaky with brain fog).

Do you have any other symptoms that doxy is helping beyond the heart stuff by chance?

Also, have you tried higher doses of doxy? Or just keeping it low?

I just started doxy at 150mg, I’m super sensitive and didn’t want to do 200mg for my covid gut. I tend to go less with most medication as that’s what my body tolerates. I’m cycling through several antibiotics with Rifaximin right now for stubborn methane SIBO.

Gut issues seem to be what improves everything for me. Everything clears up when treating my gut with various antibiotics. Just doesn’t last long enough.

But my LC specialist says doxy works on other things. So I’m thinking of just staying on it and lowering the dose to 100mg once I’ve finished my SIBO treatments…

I’m interested to know what other symptoms you have that doxy might be helping?

I read a Hypothesis Matrix theorizing doxy decreases gut permeability and gut inflammation improving MCAS and hEDS which are downstream issues of COVID gut.

Do you have any GI issues it’s helping by chance?

Warm Regards,
