Taking Cephalexin (800 mg) 4x/day, Amlodipine (10 mg) 1x/day, and Floranex-Lactobacillus 2x/day after having been in hospital for seven days with diagnosis of Group A Streptococcus following the passing of a kidney stone and blood found in urine. Came home on Friday (11/03/2017) and began the oral regimen...antibiotic for two weeks. Noticed some stinging earlier today and just now noticed tongue red down the center and lips seem dry. Drinking variety of liquids...Sprite, iced tea, cranberry, water. Next dose of antibiotic (Cephalexin) is midnight. Will call pharmacy in the morning but wondering if there is anything I should do until then? Thank you.
