Furthermore, probiotics can cause side effects such as allergy or diarrhea. At the same time co-administration of antibiotics and probiotics is not very effective, because the latter inhibit the activity of the bacteria. Besides, it is impossible to determine the optimum number of bacteria to provide a necessary effect. Therefore, it is preferred to use products that don't contain bacteria or their components.
