Subsequent Event [Line Items]            
Rights offering description         Each right will entitle the holder to purchase, at the holder’s election and subject to availability, at a subscription price of $1,000 per unit, one unit consisting of (i) a 6.500% Exchangeable Notes, to be issued by Iterum Bermuda in the original principal amount of $1,000, fully and unconditionally guaranteed on an unsecured senior subordinated basis by the Company, Iterum Therapeutics International Limited, Iterum Therapeutics US Limited and Iterum Therapeutics US Holding Limited (collectively, the Guarantors), and (ii) 50 Limited Recourse RLNs, to be issued by Iterum Bermuda, fully and unconditionally guaranteed on an unsecured senior subordinated basis by the Guarantors. The Company will only accept subscription rights for up to 8,400 units for a total purchase price of $8.4 million, which amount is approximately equal to the maximum aggregate principal amount of additional notes that may be issued under the indentures pursuant to which the Exchangeable Notes and RLNs will be issued. The Company anticipates that the subscription period for the planned rights offering will begin on or about August 11, 2020, or as soon as practicable thereafter, and continue for a period of at least 20 calendar days. A registration statement relating to the planned rights offering has been filed with the SEC but has not yet become effective. The planned rights offering will be made pursuant to such registration statement and a prospectus to be filed with the SEC prior to the commencement of the planned rights offering. The expected timing of the planned rights offering is subject to change. The Company may not receive all or any of the $8.4 million it will be seeking to raise in the planned rights offering. The Company reserves the right to cancel or terminate the planned rights offering at any time.
