Hypersensitivity.

Hepatic disease, biliary obstruction, ingestion of alcohol, pregnancy and lactation.

GI disturbances; hypersensitivity.
Potentially Fatal: Stevens-Johnson syndrome.

Probenecid may increase the serum concentrations of sulbactam.

Sulbactam, a penicillanic acid sulfone with β-lactamase inhibitory properties has weak antibacterial activity, but is an irreversible inhibitor of many plasmid-mediated and some chromosomal β-lactamases. It has a similar spectrum of β-lactamase inhibition to clavulanic acid, although it is less potent. It enhances the activity of penicillins and cephalosporins. It is usually given with ampicillin to increase the antimicrobial spectrum; may also be used with cefoperazone.
Absorption: Poorly absorbed from the GI tract.
Distribution: Distributed into breast milk. Protein binding: 38%.
Excretion: Half-life elimination: 1-1.3 hr. About 75-85% is excreted unchanged in the urine within 8 hr.

Intravenous: Sterile powder for inj: Store below 20°C.
