Since taking floradix tablets over two days i have noticed one or two small blister like spots appear on my body, is this a side effect?

Floradix side effect: Unlikely from taking it for two days. Generally medication side effects are going to be systemic and not localized. I suspect these blisters are unrelated. BTW - what are you treating with the floradix? - a potential side effect is iron overload if taken too much or too long. Have your doctor do a blood count and iron studies to see if you truly need it.
