Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergy: Before starting treatment with cefprozil, inform your doctor about any adverse reactions you have had to medications, especially cefprozil, cephalosporins, and penicillins. Some people allergic to penicillin may also be allergic to cephalosporins such as cefprozil. If you have an allergic reaction, contact a doctor.
Antibiotic-associated colitis: Like other antibiotics, this medication may cause a potentially dangerous condition called antibiotic-associated colitis (or pseudomembranous colitis). Symptoms include severe, watery diarrhea that may be bloody. If you notice these symptoms, stop taking cefprozil and contact your doctor as soon as possible.
Bacterial resistance: Misuse of an antibiotic such as cefprozil may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better when you first start taking cefprozil, you need to take all of the medication exactly as prescribed by your doctor to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take cefprozil or other antibiotics to treat a viral infection such as the common cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.
Kidney function: Kidney disease and decreased kidney function may cause this medication to build up in the body, causing side effects. People with kidney disease or reduced kidney function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Overgrowth of organisms: Prolonged or repeated use of cefprozil may result in an overgrowth of bacteria or fungi and organisms that are not killed by the medication. This can cause problems such as yeast infections.
Skin reactions: Rarely, people taking cefprozil experience a severe skin reaction that can be life-threatening. These reactions may start as a skin rash that blisters, sores on the lips, eyes, or covers a large area of the body. It can develop into an exfoliating skin condition, with peeling, shedding, or scaling of the skin. If you experience any of these symptoms, or any other unusual skin reaction of the skin, contact your doctor immediately.
Pregnancy: It is not known if cefprozil is safe for use by pregnant women. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are breast-feeding and are taking cefprozil, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: It is not known if cefprozil is safe for children under 6 months of age.
