Clarithromycin Tablets 500 mg are an antibiotic used to treat various bacterial infections, including respiratory tract infections, skin infections, and certain types of stomach ulcers. As a macrolide antibiotic, clarithromycin works by inhibiting bacterial protein synthesis, effectively stopping the growth of bacteria. These tablets are typically taken twice daily, with or without food, as prescribed by a healthcare professional. Common side effects may include nausea, diarrhea, or abdominal pain. It is important to complete the full course of treatment to prevent the development of antibiotic-resistant bacteria. Always follow your doctor’s instructions and inform them of any other medications or health conditions to ensure safe and effective use of clarithromycin.
