What is Amoxicillin clavulanate potassium?
Amoxicillin clavulanate potassium is an oral combination antibiotic that contains two active ingredients: amoxicillin and clavulanate potassium. It’s effective in treating various skin infections, including infected eczema.
Eczema is generally treated with emollients or topical steroids for more severe cases. But when the skin affected by eczema cracks and opens, it becomes easier for germs to enter, leading to infections that require treatment with antibiotics.
How does Amoxicillin clavulanate potassium work?
There are two active ingredients in Amoxicillin clavulanate potassium:[1]
- Amoxicillin is an antibiotic that works by inhibiting the system of bacterial cell walls. Without the cell wall, the bacteria can’t function properly, which weakens them. This eventually kills the bacteria.
- Clavulanate potassium is a component that stops the bacteria from destroying amoxicillin, allowing it to effectively combat bacterial infections.
