Florastor is a brand-name probiotic that contains Saccharomyces boulardii lyo, a yeast that promotes healthy bowel function, according to Drugs.com. Florastor is sold over the counter and should not be taken by patients who are allergic to yeast.
Florastor should also be avoided by patients taking anti-fungal medications, such as clotrimazole and nystatin, states Drugs.com.
While doctors generally do not recommend taking probiotics at the same time as an antibiotic, as WebMD explains, Florastor may be taken alongside antibiotics, according to its official website. The capsule may be swallowed whole, or it may be opened and mixed with juice or sprinkled over foods like applesauce for patients with trouble swallowing pills.
