Uses
Uses of cefadroxil
The Food and Drug Administration (FDA) approves prescription drugs such as cefadroxil for certain conditions. Approved uses for cefadroxil are described below.
Use for bacterial infections
Doctors may prescribe cefadroxil oral capsule, oral tablet, or oral suspension (a type of liquid mixture) for treating certain bacterial infections. It’s used for this purpose in adults and certain children. It’s usually prescribed as a short-term treatment.
Cefadroxil is used to treat infections caused by bacteria, including:
- infections of the skin
- infections of the throat and/or tonsils
- urinary tract infection (UTI)
With bacterial infections, bacteria grow and multiply in your body. Symptoms of the infection will vary depending on where the infection is located. For example, a tonsil infection can cause pain with swallowing. A UTI can cause pain or burning with urination or a frequent need to urinate. Cefadroxil can help clear bacterial infections.
FAQ
Common questions about cefadroxil
Below you’ll find answers to a few commonly asked questions about cefadroxil.
What brand names are available for cefadroxil?
Currently, there aren’t any brand-name drugs available for cefadroxil. Cefadroxil is a generic version of the brand-name drugs, Duricef and Ultracef. But these drugs are no longer on the market.
A generic medication is an identical copy of the active drug in a brand-name medication. An active drug is the ingredient that makes a medication work. Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less compared to brand-name drugs.
To find out more about this, talk with your doctor or pharmacist.
Is cefadroxil similar to Keflex or amoxicillin?
Yes, cefadroxil is similar to Keflex (cephalexin). Both of these drugs are a type of antibiotic called cephalosporin. They have similar uses, side effects, and warnings.
Cefadroxil is also similar to amoxicillin, but they aren’t in the same group of drugs. Amoxicillin is a penicillin antibiotic. Penicillin antibiotics are closely related to cephalosporin antibiotics. They often treat the same kinds of bacterial infections and have similar side effects. In addition, having an allergy to one group of drugs increases the risk of developing an allergy to the other group.
You can learn more about how cefadroxil compares with other antibiotics by talking with your doctor or pharmacist.
How does cefadroxil work? And how long does it take to start working?
Cefadroxil works by killing bacteria that are causing an infection. This helps your body get rid of the infection.
Cefadroxil will start working as soon as you take it. But it can take some time for your symptoms to go away. It’s important to keep taking cefadroxil, even when you start to feel better. Completing the full course of cefadroxil as prescribed will help stop the infection from coming back. Infections that come back are often harder to treat.
If you’d like to know more about this, talk with your doctor or pharmacist.
