Oral antibiotics are medications taken by mouth to treat bacterial infections. They work by killing bacteria or inhibiting their growth, helping the body to fight off infections. Common examples include amoxicillin and ciprofloxacin. These medications are often prescribed for conditions like strep throat, urinary tract infections, and skin infections. It is important to take oral antibiotics exactly as prescribed by a healthcare provider. Completing the full course is crucial to ensure that all bacteria are eliminated and to prevent antibiotic resistance, which occurs when bacteria adapt and become resistant to the effects of the medication.
