Others - Pregnancy & Lactation Pregnancy: No adequate and well controlled studies in pregnant women have been conducted with Ceftazidime. Because animal reproduction studies are not always predictive of human response this drug should be used during pregnancy only if clearly needed. Lactation: Ceftazidime is excreted in human milk in low concentrations. Because many drugs are excreted in human milk and because safety of the component of the injections in nursing infants has not been established, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Precautions & Warnings The total daily dosage should be reduced when Ceftazidime is administered to patients with renal insufficiency. Ceftazidime should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis. Overdose Effects Symptoms: Seizure activity, encephalopathy, asterixis, neuromuscular excitability, coma. Management: Symptomatic and supportive treatment. In the presence of renal insufficiency, haemodialysis or peritoneal dialysis may aid in the removal of the drug from the body.
