Equity [Abstract]
Stockholders' Equity/(Deficit)	Stockholders' Equity/(Deficit) In connection with the 2016 Merger and the retrospective application of the recapitalization of the Company, the par value of each share of common stock of Valeritas Holdings, Inc. of $0.001 and the authorized 300,000,000 shares of common stock and 10,000,000 shares of blank check preferred stock of Valeritas Holdings, Inc. became the capital structure of the Company. Concurrently with the closing of the 2016 Merger, and as a condition to the 2016 Merger, the Company closed a private placement offering (the "Private Placement") of approximately 0.6 million shares of common stock of Valeritas Holdings at a purchase price of $40.00 per share, for proceeds of approximately $24.0 million, net of financing costs. Existing investors of the Company invested $20.0 million of the Private Placement. The pre-2016 Merger stockholders of the Company retained an aggregate of 125,000 shares of common stock. During the three months ended March 31, 2017, the Company closed a public offering of 5,250,000 shares of common stock of Valeritas Holdings at a purchase price of $10.00 per share, for proceeds of approximately $48.8 million, net of financing costs. Existing investors of the Company invested $40.0 million in the public offering. On March 23, 2017, $25.0 million and $2.5 million of the Term Loan and WCAS Note, respectively, were converted to preferred shares. CRG and WCAS received 2,500,000 and 250,000 preferred shares, respectively. At the time of the debt restructuring, $0.1 million of remaining debt issuance costs was extinguished and recorded against equity as the lender is also a shareholder of the Company. The Company capitalized a de minimis amount of debt issuance costs in connection with the conversion. Preferred Stock In February 2017, the Company’s Board of Directors approved a proposal for a reverse stock split in any ratio up to 1-for-10 of the Company’s common stock and an increase in the number of shares of preferred stock the Company is authorized to issue to 50,000,000. On March 8, 2017, the Company’s stockholders approved, and the Company’s board of directors subsequently adopted, an eight-to-one reverse stock split of the Company’s common stock and the increase in the amount of shares of preferred stock the Company is authorized to issue. All share and per share numbers in these financial statements have been retrospectively adjusted to reflect the reverse stock split. Shares of preferred stock may be issued from time to time in one or more series, each of which will have such distinctive designation or title as shall be determined by our Board of Directors prior to the issuance of any shares thereof. Preferred stock will have such voting powers, full or limited, or no voting powers, and such preferences and relative, participating, optional or other special rights and such qualifications, limitations or restrictions thereof, as shall be stated in such resolution or resolutions providing for the issue of such class or series of preferred stock as may be adopted from time to time by the Board of Directors prior to the issuance of any shares thereof. The number of authorized shares of preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of all the then outstanding shares of our capital stock entitled to vote generally in the election of the directors, voting together as a single class, without a separate vote of the holders of the preferred stock, or any series thereof, unless a vote of any such holders is required pursuant to any preferred stock designation. On February 14, 2017, the Company entered into an agreement with CRG and WCAS to convert a total of $27.5 million of the outstanding principal amount of the Company's debt, including the Term Loan, into shares of Series A Convertible Preferred Stock at the public offering price. The shares of Series A Preferred Stock will be convertible at the option of the holder at any time into shares of the Company's common stock at a conversion rate determined by dividing the Series A Original Issue Price by the Series A Conversion Price (both as to be defined in the Certificate of Designation) in effect at the time of conversion. This formula initially results in a one-to-one conversion ratio. The Series A Conversion Price is subject to adjustment for stock splits and the like subsequent to the date of issuance of the Series A Preferred Stock. On or after January 1, 2021, at the Company's option, if the Company has achieved an average market capitalization of at least $300 million for the Company's most recent fiscal quarter, the Company may elect to automatically convert all of the outstanding shares of Series A Preferred Stock into shares of the Company's common stock. The holders of shares of Series A Preferred Stock are entitled to receive annual dividends at a rate of $8 per every $100 of Series A Preferred Stock, payable either in cash or in shares of the Company's common stock, at each holder’s election; provided, that to the extent any holder elects to receive cash dividends, such dividends shall accrue from day to day and be payable only upon a Deemed Liquidation Event (as defined in the Certificate of Designation). The shares of Series A Preferred Stock will have no voting rights. The Company has the right to redeem all or less than all of the Series A Preferred Stock, at any time, at a price equal to the Series A Conversion Price, as adjusted, plus any accrued but unpaid dividends. In the event of a Deemed Liquidation Event the holders of Series A Preferred Stock are eligible to receive the greater of (i) $27.5 million, plus accrued but unpaid dividends or (ii) what they would have received as a holder of common stock had they converted their shares of Series A Preferred Stock into shares of the Company's common stock immediately prior to the Deemed Liquidation Event. To the extent permitted under Delaware law, the holders of shares of Series A Preferred Stock have the right to prevent us from liquidating, dissolving, amending our governing documents in a manner that affects the rights of the Series A Preferred Stock, authorizing shares of capital stock on parity or senior to the Series A Preferred Stock, or issuing any shares of Series A Preferred Stock to any individual, entity or person other than CRG or WCAS.
