Tazid Injection, Im/iv Injection

Tazid is a semisynthetic, broad-spectrum, beta-lactam antibiotic for parenteral administration. Tazid is bactericidal in action exerting its effect by inhibition of enzymes responsible for cell-wall synthesis. A wide range of gram-negative organisms is susceptible to ceftazidime in vitro, including strains resistant to gentamicin and other aminoglycosides. In addition, ceftazidime has been shown to be active against gram-positive organisms. It is highly stable to most clinically important beta-lactamases, plasmid or chromosomal, which are produced by both gram-negative and gram-positive organisms and, consequently, is active against many strains resistant to ampicillin and other cephalosporins.


Sidobac Injection is used for the treatment of patients with infections caused by susceptible strains of the designated organisms in the following diseases:

Lower Respiratory Tract Infections, including pneumonia, caused by Pseudomonas aeruginosa and other Pseudomonas spp., Haemophilus influenzae, including ampicillin-resistant strains; Klebsiella spp.; Enterobacter spp.; Proteus mirabilis; Escherichia coli; Serratia spp.; Citrobacter spp.; Streptococcus pneumoniae; and Staphylococcus aureus (methicillin susceptible strains).

Skin and Skin Structure Infections caused by Pseudomonas aeruginosa; Klebsiella spp.; Escherichia coli; Proteus spp., including Proteus mirabilis and indole-positive Proteus, Enterobacter spp.; Serratia spp.; Staphylococcus aureus (methicillin susceptible strains); and Streptococcus pyogenes (group A beta-hemolytic streptococci).

Ceftazidime Structure


Tazid dosage

Dosage: 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.

Recommended Dosage Schedule

Uncomplicated urinary tract infections: 250 mg IV or IM Q 12h

Bone and joint infections: 2 grams IV Q 12h

Complicated urinary tract infections: 500 mg IV or IM Q 8-12h

Uncomplicated pneumonia; mild skin and skin structure infections: 500 mg -1 gram IV or IM Q 8h

Serious gynecologic and intra-abdominal infections: 2 grams IV Q 8h

Meningitis: 2 grams IV Q 8h

Very Severe life threatening infections, especially in immunocompromised patients: 2 grams IV Q 8h

Lung infections caused by Pseudomonas spp. In patients with cystic fibrosis with normal renal function: 30-50 mg/kg IV to a maximum of 6 grams per day Q 8h

Neonates (0 - 2 months): 25-60 mg/kg/day IV Q 12h

Infants & Children (2 months - 12 years): 30-100 mg/kg/day IV to a maximum of 6 grams per day Q 8-12h.

Impaired Hepatic Function: No adjustment in dosage is required for patients with hepatic dysfunction.

Impaired Renal Function: In patients with impaired renal function (glomerular filtration rate [GFR]<50 mL/min) it is recommended that the dosage of Tazid be reduced to compensate for its slower excretion. In patients with suspected renal insufficiency, an initial loading dose of 1 gram of Tazid may be given.


Recommended Maintenance Dosages of Tazid in renal insufficiency:

Creatinine clearance 50-31 mL/min: 1 gram Q12h

Creatinine clearance 30-16 mL/min: 1 gram Q24h

Creatinine clearance 15-6 mL/min: 500 mg Q24h

Creatinine clearance <5 mL/min: 500 mg Q48h

Administration: Sidobac 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, Sidobac should be constituted with the supplied Sterile Water for Injection.

Single-dose vial Administration Amount of WFI to be added: 

  • 250 mg IM in 1.5 ml
  • 250 mg IV in 5 ml
  • 500 mg IM in 1.5 ml
  • 500 mg IV in 5 ml
  • 1 gm IM in 3 ml
  • 1 gm IV in 10 ml

Step 1: Add recommended volume of solvent slowly. Remove the syringe needle.

Step 2: Gently shake the vial to dissolve the powder. Carbon dioxide is released & a clear solution will be obtained.

Step 3: Now insert the needle in the free space of the reconstituted vial & withdraw the pressurized air from the free space.

Step 4: Finally withdraw the solution from the vial by syringe

Side Effects

The most common side-effects are local reactions following IV injection and allergic and gastrointestinal reactions. Hypersensitivity reactions are pruritus, rash, and fever. Angioedema and anaphylaxis have been reported very rarely. Gastrointestinal symptoms are diarrhea, nausea, vomiting, and abdominal pain. Central nervous system reactions included headache, dizziness, and paresthesia.


The total daily dosage should be reduced when Tazid is administered to patients with renal insufficiency. Ceftazidine should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis.


Increased nephrotoxicity has been reported following concomitant administration of Cephalosporins and aminoglycoside antibiotics.

Food Interaction

No interactions found.

Volume of Distribution

Tazid has a volume of distribution of 15-20 L.

Half Life

Tazid has an elimination half-life of 1.5-2.8 hours in healthy subjects. As ceftazidime is primarily renally excreted, its half-life is significantly prolonged in patients with renal impairment. In patients with creatinine clearance < 12 mL/min, the half-life is prolonged to between 14 and 30 hours.


The mean renal clearance of ceftazidime in healthy subjects ranges from 72 to 141 mL/min while the calculated plasma clearance is approximately 115 mL/min.

Pregnancy & Breastfeeding use

Pregnancy: No adequate and well controlled studies in pregnant women have been conducted with Tazid. Because animal reproduction studies are not always predictive of human response this drug should be used during pregnancy only if clearly needed.

Lactation: Tazid 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.


Tazid is contraindicated in patients with known hypersensitivity to cephalosporin antibiotics.

Acute Overdose

Tazid overdosage has occurred in patients with renal failure. Reactions have included seizure activity, encephalopathy, asterixis, neuromuscular excitability, and coma. Patients who receive an acute overdosage should be carefully observed and given supportive treatment.

Storage Condition

Store below 25° C, protected from light and moisture. Reconstituted solutions are stable for up to 24 h if stored between 2°-8° C
