Hi Krissy. I am sorry you had such a horrible reaction to Mepron. I have never heard of anyone reacting this way.
Artemisinin is an herb that is often used to treat Babesiosis. Many Lyme doctors have their patients take high-quality Artemisinin along with other Babesiosis protocols. You may want to ask your doctor about this.
I have taken Mepron several times and have never had a problem with it staining teeth. I think using a teaspoon allows you to get the full dose.
