Ay, ang fosfomycin ay antibiotic talaga, best to check with your doctor or pharmacist kung kailan exactly dapat kumain, kasi it depends on the dosage at kung gaano kalaki ang effect sa stomach mo. Hindi ko dapat sabihin specifics, pero generally may certain timing ang mga ganitong medicines, kaya important talaga mag-follow ng instructions from your doctor or the medicine box, mama. Better safe than sorry, diba?
