What are common side effects associated with antibiotics?

Nausea, diarrhea, and allergic reactions are indeed well-documented common side effects associated with antibiotics. Antibiotics work by targeting bacteria, which can disrupt the normal gut flora, leading to gastrointestinal issues such as nausea and diarrhea. This disruption can also contribute to the development of Clostridium difficile infection in some patients, a more severe consequence. Allergic reactions are another significant concern, as some individuals may develop hypersensitivity reactions to certain antibiotics, ranging from mild rashes to severe anaphylaxis in rare cases. This highlights the importance of monitoring patients for any signs of adverse reactions when they are prescribed antibiotics.
