Antibiotics are antimicrobial drugs that are commonly used to treat and prevent bacterial infections. The drugs kill bacteria or effectively limit and stop their growth in the human body. Antibiotics are given as a prescription to avoid misuse since the overuse of antibiotics leads to bacterial resistance and reduced effectiveness. Therefore, consult a physician before using antibiotics. When administering antibiotics to children (and other vulnerable individuals), the parents or caregivers should supervise their intake to prevent adverse reactions related to poor dosage. Antibiotics can be administered in many forms, such as oral tablets and capsules, intravenous injections, eye drops, and ear drops, depending on the type of infection and the severity of the infection. Antibiotics are considered safe for most people but may cause some side effects, including diarrhea, vomiting, nausea, fever, allergic reactions, and yeast infections in women.
