Note: The following summaries include only those safety-related sections that have been modified, and therefore do not contain all the information needed for safe and effective prescribing. Contact the manufacturer for the complete labeling/package insert.
NB: Comparison made to 1997 Physicians' Desk Reference (PDR) if drug's labeling included in the PDR.
Drug Interactions: Terfenadine: Deletion of "Definitive interaction studies at higher doses of Diflucan have not been conducted. The use of fluconazole in patients concurrently taking drugs metabolized by the cytochrome P450 system (i.e., terfenadine, cisapride and astemizole) may be associated with elevations in serum levels of these other drugs. In the absence of definitive information at higher doses of fluconazole, the coadministration of Diflucan and such agents should be carefully monitored."
Addition of "Another study at a 400 mg and 800 mg daily dose of fluconazole demonstrated that Diflucan taken in doses of 400 mg per day or greater significantly increases plasma levels of terfenadine when taken concomitantly. The combined use of fluconazole at doses of 400 mg or greater with terfenadine is contraindicated. (See CONTRAINDICATIONS, DRUG INTERACTION STUDIES.)"
Cisapride and Astemizole (new subsection): "There have been reports of cardiac events including torsade de pointes in patients to whom fluconazole and cisapride were coadministered. The use of fluconazole in patients concurrently taking cisapride, astemizole or other drugs metabolized by the cytochrome P450 system may be associated with elevations in serum levels of these drugs. In the absence of definitive information, caution should be used when coadministering fluconazole. Patients should be carefully monitored."

Statement added "Lansoprazole has also been shown to have no clinically significant interaction with amoxicillin."
Statement deleted "Coadministration of lansoprazole with sucralfate delayed absorption and reduced lansoprazole bioavailability by approximately 30%."
Statement added "In a single-dose crossover study comparing lansoprazole 30 mg and omeprazole 20 mg, each administered alone and concomitantly with sucralfate 1 gram, absorption of the proton pump inhibitors was delayed and their bioavailability was reduced by 17% and 16%, respectively, when administered concomitantly with sucralfate."
In the following sentence, the word "lansoprazole" is replaced with proton pump inhibitors to read "Therefore, proton pump inhibitors should be taken at least 30 minutes prior to sucralfate."
The safety and effectiveness of Unasyn have not been established for pediatric patients for intra-abdominal infections.
Sentence deleted: "Currently, no anaphylactic reactions have been reported with the use of Zoladex."
