<p>The usual adult dosage is 1 gram administered intravenously or intramuscularly every 8 to 12 hours. The dosage and route should be determined by the susceptibility of the causative organisms, the severity of infection and the condition, and renal function of the patient.<br />
<br />
Ceftazidime is to be used by the parenteral route, the dosage depending upon the severity, sensitivity &amp; type of infections and the age, weight &amp; renal function of the patient.<br />
<br />
<strong>Adults</strong>: The adult dosage range for ceftazidime is 1 to 6 gm per day 8 or 12 hourly (IM/IV) in the majority of infections, 1 gm 8 hourly or 2 gm 12 hourly should be given.</p>

<ul>
	<li><strong>In urinary tract infections and many less serious infections</strong>: 500 mg or 1 gm 12 hourly is usually adequate.</li>
	<li><strong>In severe infections, especially immunocompromised patients, including those with neutropenia</strong>: 2 gm 8 or 12 hourly should be administered. When used as a prophylactic agent in prostatic surgery 1 gm should be given at the induction of anesthesia. A second dose should be considered at the time of catheter removal.</li>
</ul>

<p><strong>Elderly</strong>: In view of the reduced clearance of Ceftazidime in acutely ill elderly patients, the daily dosage should not normally exceed 3 gm, especially in those over 80 years of age.</p>

<ul>
	<li><strong>Cystic fibrosis</strong>: In fibrocystic adults with normal renal function who have pseudomonal lung infections, high doses of 100 to 150 mg/kg/day as three divided doses should be used.</li>
</ul>

<p><strong>Infants and Children</strong>: The usual dosage range for children aged over two months is 30 to 100 mg/kg/day, given as two or three divided doses. Doses up to 150 mg/kg/day (maximum 6 gm daily) in three divided doses may be given to infected immunocompromised or fibrocystic children or children with meningitis.<br />
<br />
<strong>Neonates and Children up to 2 months of age</strong>: The usual dosage range is 25 to 60 mg/kg/day as two divided doses.</p>

<p><strong>Administration</strong></p>

<p>Ceftazidime may be given intravenously or by deep IM injection into a large muscle mass such as the upper outer quadrant of the gluteus maximus or lateral proof of the thigh. Intra-arterial administration should be avoided. For IV/IM administration, Ceftazidime should be reconstituted with the supplied Sterile Water for Injection.</p>
