Effectiveness
How Clarithromycin Affects Patients
Clarithromycin is a type of antibiotic used to treat a range of bacteria, including many common types such as Staphylococcus aureus, Haemophilus influenzae, Mycoplasma, and Chlamydia. It has been found to be as effective or more effective than erythromycin against certain bacteria. Clarithromycin usually stops bacteria from reproducing, but can sometimes kill them.
How Clarithromycin works in the body
Clarithromycin works by entering bacteria cells and binding to a part of their ribosomes, which are responsible for making proteins. This binding blocks the bacteria's ability to make proteins, preventing it from reproducing and causing infection. Clarithromycin also stops enzymes that break down medicine in the liver, making it more effective.
When to interrupt dosage
The recommended dosage of Clarithromycin is contingent upon the determined condition, for instance Mycobacterium Infections, Lyme Disease and Bacterial Infections. The amount may vary as per the administration technique (e.g. Powder, for suspension or Capsule; Kit; Tablet) featured in the table below.

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.
Is clarithromycin stronger than amoxicillin?
"Clarithromycin seems to work as well as amoxicillin/clavulanate against acute maxillary sinusitis, and it may cause fewer problems with upset stomach."
Answered by AI
What are the most common side effects of clarithromycin?
"Some potential side effects of this medication include diarrhea, nausea, vomiting, stomach pain, heartburn, gas, a change in taste, and headache."
Answered by AI
Is clarithromycin and amoxicillin the same?
"This product contains two different types of antibiotics: amoxicillin, which is a penicillin-type antibiotic, and clarithromycin, which is a macrolide-type antibiotic. These antibiotics work by stopping the growth of bacteria, and they are effective against only bacterial infections."
Answered by AI
What is clarithromycin antibiotic used for?
"This drug is used to treat bacterial infections by killing the bacteria. It is also used in tandem with other drugs to treat ulcers in the duodenum, which are caused by the bacteria H. pylori. Additionally, this medication is taken to prevent and treat infection by the Mycobacterium avium complex."
