Let's take a minute to talk about your medication. This is cefadroxil. It treats infections caused by bacteria. It cannot treat infections caused by viruses, like the common cold. Cefadroxil is a type of antibiotic called a 'cephalosporin'. It is similar to penicillin. You should tell your doctor if you are allergic to penicillin or other antibiotics. You should take cefadroxil exactly how your doctor tells you to. You should separate the doses with even intervals of time. It is important to not miss doses. Cefadroxil is available as a capsule, tablet and liquid. If you take the liquid, be sure to shake the bottle well before each dose. You should measure each dose with a measuring spoon or dosing syringe, and never a household spoon. Also, remember to store the liquid in the refrigerator, and throw it away when the label says to. Most people tolerate cefadroxil well. Mild stomach upset or nausea could occur. Some people take each dose with food to reduce the chance of stomach upset. This medicine could cause a yeast infection, like a diaper rash or a vaginal infection. If these happen, you should obtain treatment. Diarrhea could occur, too. Let the doctor know right away if diarrhea lasts for more than 2 days, or if it is has blood in it. You should call your doctor right away if you notice any unusual changes to your body. This includes itching, a rash, or swelling of the face, mouth or throat. For best results with cefadroxil, you should finish the full course of therapy. Otherwise, the infection could return and become hard to treat. Also, tell your doctor if the infection does not improve in a few days, or if it gets worse instead of better.
