Thanks for posting you query to health care magic. there is no relation of folliculitis with indigestion as folliculitis is infection of hair follicle and not associated with indigestion ,so i am not understanding the purpose of taking Carithromycine . If you are having any painful lesion of hair follicle then let me know so that i can suggest you correct remedy as Staphylococcus is most common organism to causing it . Indigestion could be due to some other cause alteration in your daily food intake or timing of meal may cause such problem .for your digestive problem you should presently start to take plenty of water per day and increase green veg in your dite . Take Sachet or capsule of gut flora :DAROLAC once in day to maintain normal gut environment .presently no need for antibiotic. hope you are satisfied with my answer . feel free to communicate if any query . regards, Dr.Manish Purohit Infectious disease specialist
