Treats many types of bacterial infections and has generally few side effects
Taken once or twice a day, compared to some other antibiotics that are taken more often
Can be taken with or without food
Is an affordable generic medication and comes in different forms: tablet, capsule, and suspension
May not be a good option if you have colitis or other digestive tract problems
Not recommended to be used for the cold or flu (since these are viral illnesses)
If you're allergic to penicillins or other cephalosporin antibiotics, you might not be able to take this medication.
May have to adjust your dose if you have severe kidney problems
Finish all of the medication your provider gives you, even if you start to feel better. Stopping it early can cause the bacteria to develop resistance.
You may have diarrhea or an upset stomach when taking this medication, but it should get better soon after finishing the course. Taking cefadroxil with food or a daily probiotic may help with these symptoms. If the diarrhea gets worse, tell your provider.
If you have kidney disease, you may need a lower dose than usual to avoid build-up of the medication. Your provider or pharmacist will determine the right dose for you based on your kidney labs.
Store the suspension in the fridge and shake well before using. Discard the bottle after 14 days or after you have completed the total number of days that the provider prescribed. Using old, expired antibiotics can lead to antibiotic resistance and development of other infections.
Tell your provider or get medical help right away if you get a rash, itchy skin, trouble breathing, or swelling of your face or throat.
Cefadroxil can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: History of allergy to penicillin or other cephalosporin antibiotics
If you've had an allergic reaction from taking penicillin-type or cephalosporin antibiotics, such as trouble breathing or swelling of your face and throat, let your provider know before taking this medication. Cefadroxil may not be right for you and your provider may prescribe another antibiotic. If you experience those allergic reactions after starting on cefadroxil, seek medical attention immediately.
Risk factors: Taking cefadroxil for a long time | Recent use of other antibiotics
In rare cases, taking antibiotics like cefadroxil can increase your chance of getting a serious bacterial infection that causes severe diarrhea. This can happen up to two months after you finish taking antibiotics. If you develop severe diarrhea with watery stools after you finish the medication, talk to your provider.
Risk factors: History of kidney problems | Age 65 and older
Your body removes cefadroxil through the kidneys. If your kidneys are not working properly, you are more likely to have a build-up of cefadroxil in your body which can lead to other problems. Your provider or pharmacist will determine the right dose for you based on your kidney labs.
Risk factors: Taking cefadroxil for a non-bacterial infection
You should only take cefadroxil for bacterial infections. Using cefadroxil or other antibiotics when they are not necessary can lead to drug-resistant bacteria, which are much harder to treat.
Risk factors: Taking cefadroxil for too long
Since cefadroxil doesn't kill all bacteria, some bacteria may survive, multiply, and cause a new infection known as a "superinfection". If you develop a new fever, or get sicker while taking cefadroxil, or you find that you're not feeling better after you're done with the medication, talk to your provider right away.
