Accounting Policies [Abstract]
Basis of Presentation	Basis of PresentationOur unaudited Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. 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 U.S. GAAP for complete financial statements. The unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2022.
Principles of consolidation	In the opinion of management, all adjustments considered necessary for a fair presentation of the unaudited Condensed Consolidated Financial Statements have been included and include our accounts and accounts of all majority-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation. Some amounts in this report may not add due to rounding.
Segment Reporting	Segment Reporting Our reporting and operating segments are as follows: •Consumer Self-Care Americas ("CSCA") comprises our consumer self-care business in the U.S. and Canada. CSCA previously included our Latin American businesses until they were disposed on March 9, 2022. •Consumer Self-Care International ("CSCI") comprises our consumer self-care business outside of the U.S. and Canada, primarily in Europe and Australia. We previously had an Rx segment which was comprised of our generic prescription pharmaceuticals business in the U.S., and other pharmaceuticals and diagnostic business in Israel, which have been divested. Following the divestiture, there were no substantial assets or operations left in this segment. The Rx segment was reported as Discontinued Operations in 2021, and is presented as such for all periods in this report (refer to Note 4). Our segments reflect the way in which our chief operating decision maker, who is our CEO, makes operating decisions, allocates resources and manages the growth and profitability of the Company.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions We translate our non-U.S. dollar-denominated operations’ assets and liabilities into U.S. dollars at current rates of exchange as of the balance sheet date and income and expense items at the average exchange rate for the reporting period. Translation adjustments resulting from exchange rate fluctuations are recorded in the cumulative translation account, a component of Accumulated other comprehensive income (loss) ("AOCI"). Gains or losses from foreign currency transactions are included in Other (income) expense, net.
