AB FLO SR TABS is a sustained-release tablet formulation of an antibiotic that is commonly used to treat gastrointestinal infections. It works by inhibiting the growth of bacteria in the digestive tract, helping to alleviate symptoms such as diarrhea, abdominal pain, and nausea. The sustained-release formulation allows for a slower release of the medication, providing longer-lasting effects and reducing the frequency of dosing. It is important to follow the prescribed dosing instructions and complete the full course of treatment to ensure the infection is fully eradicated.
