Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Change in Accounting Principles [Text Block]	BASIS OF PRESENTATION AND RECENTLY ADOPTED ACCOUNTING STANDARDS Perrigo Company Limited ("PCL" or "the Company") is a private limited company incorporated in Ireland on June 28, 2013, initially under the name Blisfont Limited for the purpose of facilitating the acquisition by Perrigo Company ("Perrigo") of Elan Corporation plc ("Elan") and as of September 28, 2013 PCL directly owns Habsont Limited ("Hasbont"), which wholly owns Leopard Company ("Leopard"), which are described below. The accompanying unaudited condensed consolidated financial statements of PCL have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and other adjustments) considered necessary for a fair presentation have been included. The interim period results are not necessarily indicative of the results to be expected for the full year. In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" ("ASU 2013-02"). Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated Other Comprehensive Income ("AOCI") by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 was effective for the Company in the first quarter of fiscal 2014. The additional disclosures required by this ASU have been included in Note 7. Because this standard only impacts presentation and disclosure requirements, its adoption did not impact the Company's consolidated results of operations or financial condition. In December 2011, the FASB issued ASU 2011-11 “Disclosures about Offsetting Assets and Liabilities” ("ASU 2011-11"), as clarified with ASU 2013-01 “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities” ("ASU 2013-01") issued in January 2013. These common disclosure requirements are intended to help investors and other financial statement users better assess the effect or potential effect of offsetting arrangements on a portfolio’s financial position. They also improve transparency in the reporting of how companies mitigate credit risk, including disclosure of related collateral pledged or received. In addition, ASU 2011-11 facilitates comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. ASU 2011-11 requires entities to disclose both gross and net information about both instruments and transactions eligible for offset in the statement of financial position, and disclose instruments and transactions subject to an agreement similar to a master netting agreement. Both ASU 2011-11 and ASU 2013-01 were effective for the Company in the first quarter of fiscal 2014. Because this standard only impacts presentation and disclosure requirements, its adoption did not impact the Company's consolidated results of operations or financial condition.
