Yes, this is nothing new.
I have heard it for years, and suffered it about a month ago.
I had a chest infection and high fever. My brother, a doctor,
told me to start doxycycline for ten days.
By the forth day, my stomach was a disaster, and in both directions. On top of that, I felt like I had died and gone to H.
Needless to say, I quit taking the drug.
I took doxy for three months in haiti to fight malaria, needless to say im fine.
All of the cyclines eat my stomach alive. On the other hand, in dogs at least, doxy is the ONLY thing that will kill the tick borne disease like erlichia, and it’s a long time they have to take it, like 3 weeks I think.
Generic doxycycline is ineffective against acne (speaking from experience). Fortunately, I’m now using Retin-A, and the initial results are good. Maybe I won’t need superbug-inducing antibiotics just to meet women after all. :-)
My kids just take a pro-biotic with their anti-biotics as soon as they get put on the them. Once we started doing that, no more stomach problems with anti-biotics.
