How It Works

Cefprozil is a cephalosporin antibiotic. It works by preventing the growth of bacteria that cause infections.

Indications

Cefprozil is used to treat various infections caused by bacteria, including respiratory tract infections, skin infections, ear infections, and tonsil infections.

Contraindications

Cefprozil should not be used by individuals with a history of allergy to cefprozil or other cephalosporin antibiotics.

Side Effects

• Some people may experience nausea, vomiting, diarrhea, stomach pain, or dizziness. If these symptoms persist or worsen, it's important to inform your doctor right away.

• If you experience any severe side effects, such as persistent nausea or vomiting, unusual tiredness or weakness, yellowing of the skin or eyes, stomach pain, dark urine, signs of kidney issues (such as changes in urine volume), symptoms of infection (such as persistent sore throat or fever), easy bruising, or changes in mood (such as confusion), tell your doctor immediately.

• Cefprozil may also cause severe intestinal irritation due to a bacteria called Clostridium difficile. This condition can occur during treatment or even weeks to months after stopping the medication. Seek medical advice if you experience persistent diarrhea, abdominal cramps, or blood or mucus in your stool.

• Prolonged or repeated use of cefprozil may lead to oral or genital yeast infections. If you notice white patches in your mouth or unusual vaginal discharge, or if you experience other symptoms of a yeast infection, consult your doctor.

• This medication may reduce the effectiveness of live bacterial vaccines, such as the typhoid vaccine. Inform your healthcare provider that you are taking cefprozil before getting any immunizations.

• Older patients may be more sensitive to the side effects of cefprozil and require closer monitoring during treatment. Similarly, children may be more prone to side effects, especially skin rashes, and should also be monitored more closely.

• This medication may enhance the effects and side effects of anticoagulants (blood-thinning medications).

• Cefprozil may reduce the effectiveness of live vaccines, such as the typhoid vaccine.
