Generic Name: Cefadroxil

  • What is Cefadroxil?

    Cefadroxil, a cephalosporin antibiotic, is used in the treatment of nose, throat, urinary tract, and skin infections that are caused by certain bacteria.

  • What is the most important information I should know about Cefadroxil?

    If you are allergic to either penicillin or cephalosporin antibiotics in any form, consult your doctor before taking cefadroxil. An allergy to either type of medication may signal an allergy to cefadroxil; if a reaction occurs, it could be extremely severe. If you take the drug and experience hives, difficulty breathing, or swelling of the face or throat, seek medical attention immediately.

    Diarrhea is a common problem caused by antibiotics and usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, people can develop watery and bloody stools (with or without stomach cramps and fever) even as late as 2 or more months after having taken the last dose of the antibiotic. If this occurs, contact your doctor as soon as possible.

  • Who should not take Cefadroxil?

    If you are sensitive to or have ever had an allergic reaction to a cephalosporin antibiotic, you should not take cefadroxil.

  • What should I tell my doctor before I take the first dose of Cefadroxil?

    Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with this drug. Also, talk to your doctor about your complete medical history, especially if you have kidney problems or a history of gastrointestinal disease, particularly inflammation of the bowel (colitis).

  • How should I take Cefadroxil?

    Take this medication exactly as prescribed. It is important that you finish all of it to obtain the maximum benefit. Your doctor will only prescribe cefadroxil to treat a bacterial infection; it will not cure a viral infection, such as the common cold. It's important to take the full dosage schedule of cefadroxil, even if you're feeling better in a few days. Not completing the full dosage schedule may decrease the drug's effectiveness and increase the chances that the bacteria may become resistant to cefadroxil and similar antibiotics.

    Cefadroxil may be taken with or without food. If the drug upsets your stomach, taking it with meals may help relieve the problem. Shake the liquid suspension thoroughly before each use.

    No significant interactions have been reported with cefadroxil at this time. However, always tell your doctor about any medicines you take, including over-the-counter drugs, vitamins, and herbal supplements.

  • What are the possible side effects of Cefadroxil?

    Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking this drug.

  • Can I receive Cefadroxil if I am pregnant or breastfeeding?

    The effects of cefadroxil during pregnancy and breastfeeding are unknown. Tell your doctor immediately if you are pregnant, plan to become pregnant, or are breastfeeding.

  • What should I do if I miss a dose of Cefadroxil?
