Iam taking an antibiotics for a long time (4 mounth)i heard that i may have a dysbacteriosis cause of antibiotic ?because it kills all good bacteria in stomach too. what action should i take.
Should i take a Probiotics? it helps ?

Well of course that is the effect , from what I know no one should take antibiotics for more then 14 days, because as their name suggests , antibiotics are anti-life meds and will kill most helpful organisms in your body , so do not take them for a long period of time , and always try to Buy Flagyl or other lighter antibiotics before trying out the hard stuff, it is better to heal slower but safer then fast and with terrible effects.
