| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation The Company's unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (SEC) for interim financial information. As permitted under Generally Accepted Accounting Principles in the United States (U.S. GAAP), certain notes and other information have been omitted from the interim unaudited condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the Company's most recent Annual Report on Form 10-K, for the year ended December 31, 2024, filed with the SEC. In management's opinion, the unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company's financial position, results of operations, and cash flows. The results of operations for any interim period are not necessarily indicative of the Company's future quarterly or annual results. The Company, which is primarily located in the U.S., operates in one operating segment.

| Reclassifications | Reclassifications The prior year amounts related to the caption Inventory valuation write-down in the condensed consolidated statements of cash flows has been reclassified to conform to current year presentation. The reclassification did not affect the other condensed consolidated financial statements.
|
| Consolidation | Consolidation The Company's unaudited condensed consolidated financial statements include the accounts of Supernus Pharmaceuticals, Inc. and its wholly owned subsidiaries. These are collectively referred to herein as "Supernus" or "the Company." Supernus Pharmaceuticals, Inc. and each of its subsidiaries are distinct legal entities. All material intercompany transactions and balances have been eliminated in consolidation. The unaudited condensed consolidated financial statements reflect the consolidation of entities in which the Company has a controlling financial interest. In determining whether there is a controlling financial interest, the Company considers if it has a majority of the voting interests of the entity, or if the entity is a variable interest entity (VIE) and if the Company is the primary beneficiary. In determining the primary beneficiary of a VIE, the Company evaluates whether it has both: the power to direct the activities of the VIE that most significantly impact the VIE's economic performance; and the obligation to absorb losses of, or the right to receive benefits from the VIE that could potentially be significant to that VIE. The Company's judgment with respect to its level of influence or control of an entity involves the consideration of various factors, including the form of an ownership interest; representation in the entity's governance; the size of the investment; estimates of future cash flows; the ability to participate in policymaking decisions; and the rights of the other investors to participate in the decision making process, including the right to liquidate the entity, if applicable. If the Company is not the primary beneficiary of the VIE, and an ownership interest is maintained in the entity, the interest is accounted for under the equity or cost methods of accounting, as appropriate. The Company continuously assesses whether it is the primary beneficiary of a VIE as changes to existing relationships or future transactions may affect its conclusions.
|
| Use of Estimates | Use of Estimates The Company bases its estimates on: historical experience; forecasts; information received from its service providers; information from other sources, including public and proprietary sources; and other assumptions that the Company believes are reasonable under the circumstances. Actual results could differ materially from the Company's estimates. The Company periodically evaluates the methodologies employed in making its estimates.
|
| Advertising Expense | Advertising Expense Advertising expense includes the cost of promotional materials and activities, such as printed materials and digital marketing, marketing programs and speaker programs. The cost of the Company's advertising efforts is expensed as incurred.
|
| Insurance Recoveries | Insurance Recoveries The Company has several policies with third-party insurers that provide for the recovery of certain costs incurred by the Company. The Company records its rights to insurance recoveries as a receivables when the respective costs are reimbursable under applicable insurance policies, it is probable that such costs will be reimbursed, and reimbursement can be reasonably estimated. As such, the Company estimates the percentage of costs that will be reimbursed by the insurance provider to determine the proper amount to record for the insurance recovery receivable.
