Listeriosis is a disease caused by infection with the bacterium Listeria monocytogenes, and it is most often contracted after eating contaminated foods or liquids. Listeriosis most commonly affects newborns, the elderly, pregnant women, and those individuals with a poorly functioning immune system (immunocompromised).
I have been on Plaquenil and can tell you my diarrhea started within days of starting the med. My doctor warned me that diarrhea and weight loss were side effects. I said, Well, I am usually very constipated and could stand to lose 10 pounds so this could be a good thing.. haha.
you may also experience nausea cramping bloating and bowel urgency diarrhea is generally not harmful but it can become serious therefore if you experience blood in your stools a fever a strong pain in your abdomen or diarrhea for more than three days contact your doctor taking high doses of certain vitamins can cause side effects including diarrhea hence consult your doctor before adding vitamin supplements to your diet
