For penicillin allergic people, aztreonam or a quinolone with metronidazole may be used. In cases of severe inflammation, shock, or if the person has higher risk for general anesthesia (required for cholecystectomy), an interventional radiologist may insert a percutaneous drainage catheter into the gallbladder ('percutaneous cholecystostomy tube') and treat the person with antibiotics until the acute inflammation resolves. A cholecystectomy may then be warranted if the person's condition improves. Homeopathic approaches to treating cholecystitis have not been validated by evidence and should not be used in
