Indications
Additional Information for all patients Regardless of patient age or weight, higher doses of up to 1 gm four times daily may be required for infections which are chronic or severe. Treatment should continue for at least 2 to 3 days after symptoms have resolved or bacteria have been eradicated. To reduce the possibility of rheumatic fever or glomerulonephritis resulting from infections with haemolytic streptococci, treatment should be continued for at least 10 days. Throughout treatment of chronic urinary tract infections and for several months thereafter, regular bacteriological and clinical monitoring is required. Doses below those recommended above should not be prescribed. Paediatric dosages should not exceed those specified for adults, regardless of severity of infection. It may be necessary to continue Cephradine therapy for several weeks in persistent infections. Patients may be transferred from intramuscular/intravenous Cephradine therapy to oral treatment at the same dosage level.
Pharmacology
Cephradine is a semisynthetic broad spectrum bactericidal antibiotic, it is active against infections caused by both gram-positive and gram-negative microorganisms. Both penicillinase producing and nonproducing staphylococci are sensitive to Cephradine. The main site of action of Cephradine is the cell wall of bacteria. Cell wall of sensitive organism contains peptidoglycan. Cephradine inhibits cross-linking process and as a result cell wall with many pores are formed, thus lysis of bacteria occur due to external osmotic pressure.
Dosage Administration
-Adults:Children:Elderly: The normal adult dose is appropriate. Patients with impaired renal or hepatic function should be monitored during treatment.-
Contraindications
Limited essentially to gastro-intestinal disturbances and on occasions to hypersensitivity phenomena.

Skin reactions have occasionally been reported. Rare- Glossitis, heartburn, dizziness, tightness in the chest, nausea, vomiting, diarrhoea, abdominal pain, vaginitis, candida overgrowth.

Side Effects
Although animal studies have not demonstrated any teratogenicity, safety in pregnancy has not been established. Cephradine is excreted in breast milk and should be used with caution in lactating mothers. Since the medicine may cause dizziness, patients should be cautioned about operating hazardous machinery, including automobiles.
Pregnancy And Lactation
Prolonged use of an anti-infective may result in the development of superinfection due to the emergence of resistant organisms. Cephradine should be administered with care to patients hypersensitive to penicillins because of the risk of cross-sensitivity between beta-lactam antibiotics. Cephalosporin antibiotics may cause a positive result in Coombs� testing. When Coombs testing is performed on neonates whose mothers received cephalosporins prior to labour, it should be noted that a positive result may be due to the drug. Cephradine may cause a false positive urine glucose result when Benedict�s or Fehling�s solutions or tablets such as Clinitest are used in the testing. This does not occur with enzyme-based tests (e.g. Clinistix, Diastix). Dosage adjustment is necessary in renal impairment. This product contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
