Why is it prescribed?
Cefadroxil is used to treat infections caused by various bacteria. This material will be limited to the treatment of respiratory tract infections (e.g. pneumonia).
Along with its needed effects, cefadroxil may cause some unwanted or undesirable effects. Generally, cefadroxil is well tolerated and many people will not experience unwanted effects. The frequency and severity of these effects is dependant on many factors including dose, duration of therapy and individual susceptibility. Possible unwanted effects include:
- stomach ache
- allergic reaction (hives, itching, rash, difficulty breathing)
- secondary fungal infection (yeast infection)
- itching in genital and vaginal areas
Cefadroxil is an antibiotic medication that kills various bacteria. It works by inhibiting the synthesis of one of the building blocks needed for the bacteria to make its cell wall. This results in a cell wall that is defective and more likely to rupture. The effectiveness of cefadroxil depends on factors such as dose, concentration in the blood as well as other body fluids and tissue, and the susceptibility of the bacteria. Cefadroxil does not kill all types of bacteria, but only those that have a sensitivity to this antibiotic. Infections caused by bacteria that are not sensitive to cefadroxil will not show improvement after taking this medication.
Taking the antibiotic repeatedly or for prolonged periods may result in bacterial or fungal overgrowth which can lead to a second infection. When this occurs, the cefadroxil may need to be stopped and another antibiotic prescribed to treat the new infection.
Diarrhea often develops while taking cefadroxil. This is sometimes caused by an overgrowth of bacteria in the gut that are not killed by the antibiotic. In severe cases, this may be life threatening and would require treatment with other antibiotics. In mild cases, symptoms disappear shortly after the drug is discontinued.
There is some evidence to show that people who are allergic to penicillin may also be allergic to cefadroxil and vice versa. Be sure to inform your doctor and pharmacist of any antibiotic allergy or suspected allergy that you may have had in the past. Use is not recommended in the following situations:
allergy to cephalosporins (e.g. cephalexin)
Caution is recommended in the following situations:
- kidney disease
- allergy to penicillin
- stomach or intestinal disease (e.g. colitis)
- prolonged, repeated therapy
False positive direct Coombs' tests (test used in detecting a type of blood disorder) may be caused by cefadroxil.
Cefadroxil may give false urine test results for glucose.
Use in pregnancy: Cefadroxil is considered safe to use if pregnant. Consult your doctor or pharmacist before use.
Use while breastfeeding: Cefadroxil does appear in breast-milk but is considered safe if breastfeeding. Consult your doctor or pharmacist before you take this medication while breastfeeding.
