My daughter is currently on 100 Bactrim, 300 omnicef, 250 azith daily and then tindamax twice (once daily) on the weekends. She takes 1 theralac probiotic daily and two on the weekends (30 billion units) We are changing out the omnicef for rifampin either 300 mg daily or 600 (i have to check rx). What kind and dosage of probiotics do you recommend with this dose of medicine? To date she has not had any issues with what we are on but it seems like rifampin is stronger. Thanks!
