<p>Potential interactions between Pimecrolimus Cream, 1% and other drugs, including immunizations, have not been systematically evaluated. Due to low blood levels of pimecrolimus detected in some patients after topical application, systemic drug interactions are not expected, but cannot be ruled out. The concomitant administration of known CYP3A family of inhibitors in patients with widespread and/or erythrodermic disease should be done with caution. Some examples of such drugs are&nbsp;erythromycin, itraconazole, ketoconazole, fluconazole, calcium channel blockers and cimetidine.</p>
