Cefadroxil is the active ingredient of Cipadur and Dacef.

General information

Cefadroxil is a broad-spectrum antibiotic effective in treating a variety of bacterial infections. It is frequently prescribed to treat upper and lower respiratory tract infections, urinary tract infections, and skin and soft tissue infections cause by organisms that are susceptible to cefadroxil.

It is important to note that this medication is only effective against bacterial infections - if your infection is the result of a viral or fungal infection, it will be ineffective.

Antibiotic resistance - when bacteria develop the ability to defend themselves against the effect of an antibiotic - occurs frequently with many antibiotics. The most common causes for this are when patients do not complete the prescribed course in full, allowing antibiotics to recover from treatment; and when using antibiotics for non-bacterial infections such as cold and flu.

Persons who are allergic to penicillin should take cefadroxil with caution. Although it is not a penicillin, cross-sensitivity - meaning that you may also be allergic to this drug - may occur.

How does cefadroxil work?

Cefadroxil weakens the bacterial cell wall and allows water to enter the cell, causing cells to burst.
