Cefadroxil is a first-generation cephalosporin antibiotic used to treat a wide range of bacterial infections.
Cefadroxil is a member of the first-generation cephalosporin class of antibiotics. It works by stopping certain bacteria from building their cell walls, which leads to the bacteria’s death. In Hong Kong, Cefadroxil is prescribed for a range of common infections and can be found in products such as Duricef and generic Cefadroxil tablets or suspensions.
The two main Cefadroxil-based medicines available locally are Duricef (the branded tablet) and generic Cefadroxil tablets and oral suspensions. Both are supplied in strengths of 250 mg and 500 mg, with the suspension typically offering a 125 mg/5 mL concentration for easier dosing in children. While the branded version carries the Duricef name, the generic forms are marketed simply as Cefadroxil and may be listed on the Hong Kong Hospital Authority formulary. All of these products are oral tablets or liquid preparations approved for outpatient use.
These conditions are typically caused by bacteria that are known to respond to first-generation cephalosporins. Cefadroxil is chosen because it reaches effective levels in the skin, lungs, urinary system and middle ear, helping the body clear the infection more rapidly.
Cefadroxil interferes with the construction of the bacterial cell wall, a structure that keeps the cell intact. Without a proper wall, the bacteria cannot survive and are eliminated by the immune system. The drug begins to act shortly after it is absorbed, so patients often notice improvement in symptoms within a few days of starting therapy.
If any of these serious signs appear, immediate medical attention is recommended.

Cefadroxil tablets should be stored in a cool, dry place away from direct sunlight, while the oral suspension should be kept refrigerated after reconstitution. Treatment courses are usually short, ranging from a few days for uncomplicated infections to up to two weeks for more persistent cases. Always follow the specific instructions that accompany your chosen Cefadroxil medication, as formulations and strengths differ between Duricef and generic products. For detailed usage, dosing, and administration, refer to your specific medication's information.
