cefadroxil FDA prescribing information indications warnings
Cefadroxil 500 mg is a prescription oral antibiotic in the first-generation cephalosporin group. It treats certain bacterial infections, not viral illnesses such as colds or flu.
Common uses, when the bacteria are susceptible:
- Throat infection / tonsillitis caused by group A Streptococcus
- Skin and soft-tissue infections such as cellulitis, impetigo, or infected wounds caused by staphylococci or streptococci
- Urinary tract infections (UTIs) caused by certain bacteria, including E. coli, Proteus mirabilis, and Klebsiella species
It works best against many gram-positive bacteria such as streptococci and methicillin-sensitive staphylococci. It does not reliably treat MRSA or every UTI, so culture results and local resistance matter. The official cefadroxil prescribing information lists UTI, skin infections, and streptococcal pharyngitis/tonsillitis as indications.
Important safety points
- Do not take it if you have had a serious allergy to cefadroxil or another cephalosporin. Tell the prescriber about any penicillin allergy.
- Kidney disease may require a dose adjustment.
- Common adverse effects: nausea, stomach upset, loose stools, rash.
- Seek urgent help for facial/lip swelling, breathing difficulty, severe rash, or severe/watery or bloody diarrhea.
- Take it exactly as prescribed and finish the course unless your clinician tells you to stop. Do not use leftover antibiotics or share them.
The 500 mg strength is the amount in each tablet/capsule. The correct frequency and duration depend on the infection, age, kidney function, and prescription.
