Important drug interactions
Rants and Screeds
I am proud to say that in 15 years I have yet to find a reason to give this antibiotic. E-mail me if you have found an indication.
Beta-lactamse inhibitor combinations are problematic with some gram negative rods, depending on the strain and the type of beta-lactamase. Clavulanate can be antagotistic for ticarcillin (PubMed) and other beta lactam antibiotics (PubMed). This is less of a problem with tazobactam, maybe occuring 1% of the time (PubMed).
Treatment of choice
Got me. Costs too much, too much resistance, better alternatives. I have used Ticarcillin/clavulanate as a marker that the prescriber knows little if anything about the rational use of antibiotics. I believe that it is both 100% sensitive and specific. It has indications for Arthritis, Cellulitis, Cystic fibrosis, Diverticulosis/itis, Empyema, Endometritis, eye infections, gynecologic infections, Intra abdominal infections, Neutropenic fever, Osteomyelitis, Pneumonia, Sepsis, Sinusitis, surgical prophylaxis, UTI.
