Cefprozil

Cefprozil or Cefzil, bacteria-fighting drug in a group known as cephalosporin antibiotics. It is commonly used to treat mild or moderate infections of the throat, ear, and respiratory tract, including strep throat, pneumonia, tonsillitis (swollen and inflamed tonsils), and bronchitis (inflammation of the bronchi, the air passages that connect the windpipe to the lungs), as well as skin infections. Cefprozil works by interfering with the invading bacteria’s ability to multiply in the body.

Cefprozil must be prescribed by a doctor. It is available in tablet and liquid form, which are both taken orally. The typical dosage for adults and children over age 12 is 500 mg per day, taken in one or two doses. The dose for children under age 12 is determined by body weight and the infection being treated.

Cefprozil works fastest when taken on an empty stomach, but it may be taken with food if it causes stomach upset. Effectiveness is usually seen after three to five days, but to avoid a recurrence of infection, the entire course of medication should be taken. However, prolonged use of this drug is not recommended, as it may lead to a secondary infection.

Patients with diabetes should be aware that cefprozil may affect the accuracy of urine glucose-monitoring tests. Patients with kidney disorders or with colitis or other gastrointestinal problems should use this drug with caution. Its safety for use during pregnancy has not been determined, and nursing mothers should be aware that this drug may appear in breast milk.

Nausea is this drug’s most common side effect. Less common side effects include diarrhea, hives, genital itching, skin rash (including diaper rash), abdominal pain, insomnia, dizziness, confusion, headache, nervousness, drowsiness, vomiting, and yellowing of the eyes and skin.

A severe allergic reaction to cefprozil may occur in patients who are sensitive to both cephalosporin antibiotics and penicillin. This drug may interact adversely with other antibiotics, certain diuretics (medications that increase urination), diarrhea medications, and oral contraceptives
