Summary
Clarithromycin is used to treat bacterial infections, which are illnesses caused by harmful bacteria. It is effective against respiratory tract infections, which affect the lungs and airways, skin infections, and certain stomach ulcers caused by Helicobacter pylori, which is a type of bacteria that can cause stomach problems.
Clarithromycin works by stopping the growth of bacteria. It binds to the bacterial ribosome, which is a part of the cell that makes proteins. By blocking protein synthesis, it prevents bacteria from growing and multiplying, helping the body's immune system fight off the infection.
Clarithromycin is usually taken as a tablet, with a typical dose for adults being 250 mg to 500 mg twice daily. It can be taken with or without food. The exact dosage depends on the type and severity of the infection and should be taken as prescribed by a doctor.
Common side effects of Clarithromycin include nausea, which is a feeling of sickness in the stomach, diarrhea, which is loose or watery stools, and changes in taste. These effects are usually mild and may go away on their own.
Clarithromycin should not be taken by people allergic to it or its ingredients. It can cause liver problems, especially in those with pre-existing liver conditions, and may affect heart rhythm. Always inform your doctor about your medical history and other medications to avoid potential risks.
