Description of Business	1. Description of Business Antares Pharma, Inc. (“Antares” or the “Company”) is an emerging, specialty pharmaceutical company focusing on the development and commercialization of self-administered parenteral pharmaceutical products and technologies. The Company has numerous partnership arrangements with several industry leading pharmaceutical companies, as well as multiple internal product development programs. The Company develops and manufactures, for itself and with its partners, novel, pressure-assisted injector devices, with and without needles, which allow patients to self-inject drugs. It makes a reusable, needle-free spring action injection device which is marketed through its partners for use with human growth hormone (hGH). The Company has also developed variations of the needle-free injector by adding a small shielded needle to a pre-filled, single-use disposable injector, called the Vibex ® In February 2014, the Company launched its product OTREXUP™ (methotrexate) injection, which is the first subcutaneous methotrexate for once weekly self-administration with an easy-to-use, single dose, disposable auto injector approved by the U.S. Food and Drug Administration (“FDA”). OTREXUP™ is indicated for adults with severe active rheumatoid arthritis (“RA”), children with active polyarticular juvenile idiopathic arthritis and adults with severe recalcitrant psoriasis (“psoriasis”). To date, Antares has received FDA approval for dosage strengths of 7.5 mg, 10 mg, 15 mg, 20 mg and 25 mg of OTREXUP™. The Company has other products at various stages of development and approval. Antares is developing Vibex ® ® ® The Company has formed significant strategic alliances with several leading pharmaceutical companies, including Teva Pharmaceutical Industries, Ltd. (“Teva”), Ferring Pharmaceuticals Inc. and Ferring B.V. (together “Ferring”), and JCR Pharmaceuticals Co., Ltd. (“JCR”).

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. for interim financial information and with the instructions to Form 10-Q and Article 10 of the Securities and Exchange Commission’s Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the U.S. for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The accompanying consolidated financial statements and notes thereto should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. Operating results for the three and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. Certain prior year amounts have been reclassified in the consolidated financial statements to conform to the current year presentation. These reclassifications were made to present selling, general and administrative expenses in one line in the consolidated statements of operations. In prior years, sales and marketing expenses and general and administrative expenses were presented in separate lines. These reclassifications had no effect on previously reported net income or total operating expenses. Investments All short-term and long-term investments are U.S. Treasury bills or U.S. Treasury notes that are classified as held-to-maturity because of the Company’s positive intent and ability to hold the securities to maturity. The securities are carried at their amortized cost and the fair value of all securities is determined by quoted market prices. At June 30, 2015 and December 31, 2014, the Company’s short-term investments had a carrying value of $6,001,895 and $6,002,438, respectively. As of June 30, 2015, the Company had long-term investments with a carrying value of $9,016,818, and held no long-term investments as of December 31, 2014. The carrying value of the Company’s short-term and long-term investments as of June 30, 2015 and December 31, 2014, approximated fair value. Inventories Inventories are stated at the lower of cost or market. Cost is determined on a first-in, first-out basis. Certain components of the Company’s products are provided by a limited number of vendors, and the Company’s production, assembly, warehousing and distribution operations are outsourced to third-parties where substantially all of the Company’s inventory is located. Disruption of supply from key vendors or third-party suppliers may have a material adverse impact on the Company’s operations. The Company provides reserves for potentially excess, dated or obsolete inventories based on an analysis of inventory on hand compared to forecasts of future sales. Inventories consist of the following: June 30, December 31, 2015 2014 Inventories: Raw material $ 388,499 $ 461,396 Work in process 3,243,499 3,896,837 Finished goods 1,833,570 1,501,691 $ 5,465,568 $ 5,859,924 Capitalized Patent Costs The Company capitalizes external legal patent defense costs and costs for pursuing patent infringements when it determines that a successful outcome is probable and will lead to an increase in the value of the patent. The capitalized costs are amortized over the remaining life of the related patent. If changes in the anticipated outcome were to occur that reduce the likelihood of a successful outcome of the entire action to less than probable, the capitalized costs would be charged to expense in the period in which the change is determined. As of June 30, 2015 and December 31, 2014, approximately $1,800,000 in external legal patent defense costs were capitalized within patent rights, net. Product Revenue In February 2014, the Company began detailing OTREXUP™ to health care professionals in the U.S. and began shipping to wholesale pharmaceutical distributors, subject to rights of return within a period beginning six months prior to, and ending 12 months following, product expiration. Given the limited sales history of OTREXUP™, the Company currently cannot reliably estimate expected returns of the product at the time of shipment. Accordingly, recognition of revenue is deferred on product shipments of OTREXUP™ until the right of return no longer exists, which occurs at the earlier of the time OTREXUP™ units are dispensed through patient prescriptions or expiration of the right of return. Units dispensed are generally not subject to return, except in the rare cases where the product malfunctions or the product is damaged in transit. Patient prescriptions dispensed are estimated using third-party market prescription data. These third-party sources poll pharmacies, hospitals, mail order and other retail outlets for OTREXUP™ prescriptions and project this sample on a national level. If patient prescriptions dispensed for a given period are underestimated or overestimated, adjustments to revenue may be necessary in future periods. The Company recognized $3,346,094 and $6,350,403 in OTREXUP™ product revenue for the three and six months ended June 30, 2015, respectively, as compared to $1,671,470 and $1,884,315 for the three and six months ended June 30, 2014, which is presented net of product allowances for estimated wholesaler discounts, prompt pay discounts, chargebacks, rebates and patient discount programs. The Company had deferred revenue balances of $986,517 and $1,061,947 at June 30, 2015 and December 31, 2014, respectively, for OTREXUP™ product shipments, which is net of product sales allowances. The Company will continue to recognize revenue upon the earlier to occur of prescription units dispensed or expiration of the right of return until it can reliably estimate product returns, at which time the Company will record a one-time increase in net revenue related to the recognition of revenue previously deferred. In addition, the costs of manufacturing OTREXUP™ associated with the deferred revenue are recorded as deferred costs, which are included in inventory, until such time as the related deferred revenue is recognized. Product Sales Allowances The Company recognizes product sales allowances as a reduction of product sales in the same period the related revenue is recognized. Product sales allowances are based on amounts owed or to be claimed on the related sales. These estimates take into consideration the terms of our agreements with customers and third-party payors and the levels of inventory within the distribution channels that may result in future rebates or discounts taken. In certain cases, such as patient support programs, the Company recognizes the cost of patient discounts as a reduction of revenue based on estimated utilization. If actual future results vary, it may be necessary to adjust these estimates, which could have an effect on product revenue in the period of adjustment. Product sales allowances include: Wholesaler Distribution Fees Prompt Pay Discounts Chargebacks Rebates Patient Discount Programs

Equity [Abstract]
Stockholders' Equity	4. Stockholders’ Equity On May 11, 2015, the Company completed an underwritten offering of 23,000,000 shares of its common stock at a price to the public of $2.00 per share. The Company received net proceeds of approximately $42.8 million after deducting underwriting discounts, commissions and offering expenses paid by the Company. The Company intends to use the net proceeds from the offering for general corporate purposes including business development, in-licensing and acquisitions. The Company’s 2008 Equity Compensation Plan (the “Plan”) allows for grants in the form of incentive stock options, nonqualified stock options, stock units, stock awards, stock appreciation rights, and other stock-based awards. All of the Company’s officers, directors, employees, consultants and advisors are eligible to receive grants under the Plan. The maximum number of shares authorized for issuance under the Plan is 21,000,000 and the maximum number of shares of stock that may be granted to any one participant during a calendar year is 1,000,000 shares. Options to purchase shares of common stock are granted at exercise prices not less than 100% of fair market value on the dates of grant. The term of each option is ten years and the options typically vest in quarterly installments over a three-year period. As of June 30, 2015, the Plan had 365,599 shares available for grant. Stock Options A summary of stock option activity under the Plan as of June 30, 2015, and the changes during the six months then ended is as follows: Number of Shares Weighted Weighted Average Aggregate Outstanding at December 31, 2014 7,245,485 2.25 Granted 2,801,510 2.23 Exercised — — — Cancelled/Forfeited (170,754 ) 3.19 Outstanding at June 30, 2015 9,876,241 2.22 7.2 2,818,000 Exercisable at June 30, 2015 5,657,117 2.04 5.4 2,818,000 The per share weighted average fair values of all options granted during the first half of 2015 and 2014 were estimated as $1.10 and $3.08, respectively, on the date of grant using the Black-Scholes option pricing model based on the assumptions noted in the table below. Expected volatilities are based on the historical volatility of the Company’s stock price. The weighted average expected life is based on both historical and anticipated employee behavior. June 30, 2015 2014 Risk-free interest rate 1.3 % 1.7 % Annualized volatility 53.8 % 62.0 % Weighted average expected life, in years 6.0 6.0 Expected dividend yield 0.0 % 0.0 % There were no stock option exercises in the first six months of 2015. In the first six months of 2014, 699,678 stock options with a weighted average exercise price of $1.24 were exercised which generated proceeds of $870,726 to the Company. Total recognized compensation expense for stock options was $1,411,005 and $807,727 for the first six months of 2015 and 2014, respectively and totaled $770,214 and $447,831 for the three month periods ended June 30, 2015 and 2014, respectively. As of June 30, 2015, there was $4,557,345 of total unrecognized compensation cost related to nonvested outstanding stock options that is expected to be recognized over a weighted average period of approximately 2.16 years. Long Term Incentive Program (LTIP) The Company’s Board of Directors has approved a long term incentive program (“LTIP”) for the benefit of the Company’s senior executives. Pursuant to the LTIP, the Company’s senior executives have been awarded stock options, restricted stock units (“RSU”) and performance stock units (“PSU”) with targeted values based on values granted by the Company’s peer group. The stock options have a ten-year term, have an exercise price equal to the closing price of the Company’s common stock on the date of grant, vest in quarterly installments over three years, were otherwise granted on the same standard terms and conditions as other stock options granted pursuant to the Plan and are included in the stock options table above. The RSUs vest in three equal annual installments. The PSU awards made to the senior executives vest and convert into shares of the Company’s common stock based on the Company’s attainment of certain performance goals over a performance period of three years. The performance stock unit awards and restricted stock unit awards granted under the long term incentive program are summarized in the following table: Performance Stock Units Restricted Stock Number of Weighted Number of Weighted Outstanding at December 31, 2014 463,542 3.08 231,124 3.07 Granted 664,391 2.09 664,391 2.18 Vested — (80,781 ) 3.11 Forfeited/Expired (40,453 ) 3.09 (13,485 ) 3.09 Outstanding at June 30, 2015 1,087,480 2.59 801,249 2.33 In 2015 and 2014, the LTIP awards include PSUs that will be earned based on the Company’s total shareholder return (“TSR”) as compared to the Nasdaq Biotechnology Index (“NBI”) at the end of the performance period, which performance period is January 1, 2014 to December 31, 2016 for the 2014 award and January 1, 2015 to December 31, 2017 for the 2015 award. Depending on the outcome of the performance goal, a recipient may ultimately earn a number of shares greater or less than their target number of shares granted, ranging from 0% to 150% of the PSUs granted. The fair values of the TSR PSUs granted in May 2015 and 2014 was determined using a Monte Carlo simulation and utilized the following inputs and assumptions: 2015 2014 Closing stock price on grant date $ 2.18 $ 3.09 Performance period starting price $ 2.57 $ 4.08 Term of award (in years) 2.59 2.59 Volatility 60.45 % 50.87 % Risk-free interest rate 0.83 % 0.61 % Expected dividend yield 0.00 % 0.00 % Fair value per TSR PSU $ 1.71 $ 2.64 The performance period starting price is measured as the average closing price over the last 20 trading days prior to the performance period start. The Monte Carlo simulation model also assumed correlations of returns of the prices of the Company’s common stock and the common stocks of the NBI companies and stock price volatilities of the NBI companies. The fair value of the target number of shares that can be earned under the TSR PSUs is being recognized as compensation expense over the performance period. Total compensation expense recognized in connection with PSU awards totaled $62,638 in the first six months of 2015. The Company recognized a net expense reduction of $47,955 in the first six months of 2014 due to the forfeiture of PSU awards in connection with the departure of the former CEO. Compensation expense recognized in the first six months of 2015 and 2014 in connection with the RSUs was $177,275 and $100,752, respectively. Shares issued in connection with PSU and RSU awards that vested in the first half of 2015 and 2014 were net-share settled such that the Company withheld shares with a value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The total shares withheld to satisfy tax obligations were 29,914 and 38,768 in the six months ended June 30, 2015 and 2014, respectively, and were based on the fair value of the shares on their vesting date as determined by the Company’s closing stock price. Total payments for the employees’ tax obligations to the taxing authorities were $67,924 and $154,397 in the six months ended June 30, 2015 and 2014, respectively, and are reflected as a financing activity within the consolidated statements of cash flows. These net-share settlements had the effect of share repurchases by the Company as they reduced the number of shares that would have otherwise been issued as a result of the vesting and did not represent an expense to the Company. Warrants In the first six months of 2014, the Company received proceeds of $545,000 from the exercise of 545,000 warrants. There were no warrants outstanding at June 30, 2015 or December 31, 2014. Stock Awards At times, the Company makes discretionary grants of its common stock to members of management and other employees in lieu of cash bonus awards or in recognition of special achievements. There were no discretionary grants of common stock in the first six months of 2015. In the first six months of 2014, there were 150,000 shares of common stock granted to members of executive management as bonus compensation for achievements in 2013. In addition to the shares granted to members of management and employees, at times directors receive a portion of their annual compensation in shares of Company common stock. In 2015 and 2014, no shares were granted to the directors, as all directors’ compensation was paid in cash and stock options. Expense is recognized on a straight line basis over the one-year period in which the compensation is earned. Expense recognized in connection with shares granted to directors in 2013 was $163,456 and $343,073 for the three and six month periods ended June 30, 2014, respectively.

Net Loss Per Share	5. Net Loss Per Share Basic loss per common share is computed by dividing net loss applicable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted loss per common share reflects the potential dilution from the exercise or conversion of securities into common stock. Potentially dilutive stock options and warrants excluded from dilutive loss per share because their effect was anti-dilutive totaled 9,876,241 and 8,853,417 at June 30, 2015 and 2014, respectively.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings	7. Legal Proceedings In the first quarter of 2014, medac Pharma, Inc. (“Medac Pharma”) announced that it submitted a New Drug Application (“NDA”) to the FDA for an auto-pen containing methotrexate. On February 28, 2014, Antares filed a complaint against Medac Pharma and medac GmbH, the parent company of Medac Pharma, (medac GmbH, together with Medac Pharma, “Medac”) in the U.S. District Court for the District of Delaware, alleging infringement of two of the Company’s patents for technology regarding an auto injector and an auto injector containing methotrexate. On March 14, 2014, Antares filed a motion for preliminary injunction seeking to enjoin Medac from selling its methotrexate auto-pen product if and when such product is approved for sale in the United States, pending the final resolution of the litigation. On April 18, 2014 an amended complaint was filed asserting four Antares patents, and the motion for preliminary injunction was updated. On July 10, 2014, the District Court denied Antares’ motion for preliminary injunction. Antares filed an appeal of the denial of the motion for preliminary injunction with the U.S. Court of Appeals for the Federal Circuit, and in February 2015, that motion was denied. In 2014, a total of approximately $1,800,000 in legal costs in connection with this suit was capitalized. On March 7, 2014, Medac filed suit against Antares, LEO Pharma, Inc. and its parent company, LEO Pharma A/S (LEO Pharma, Inc. together with LEO Pharma A/S, the “LEO Entities”) in the U.S. District Court for the District of New Jersey, alleging that Antares and the LEO Entities infringe Medac Pharma’s U.S. Patent 8,664,231 (the “231 patent”) that was issued by the U.S. Patent and Trademark Office on March 4, 2014. Under the terms of the promotion and license agreement between the Company and the LEO Entities, the Company agreed to indemnify the LEO Entities from claims that OTREXUP™ infringes the intellectual property rights of any third party. On July 1, 2014, Antares filed a petition with the Patent Trial and Appeal Board (the “PTAB”) of the U.S. Patent and Trademark Office seeking an inter partes review of the 231 patent, and in January 2015, the PTAB decided to institute review of the 231 patent. Legal costs in connection with this suit and the inter partes review were expensed as incurred. In April 2015, Antares, Medac and the LEO Entites entered into a settlement agreement pursuant to which all of the proceedings related to Antares’ and Medac’s respective patents mentioned above and the proceeding pending before the Technical Board of Appeal of the European Patent Office were dismissed. The settlement agreement also provides for a royalty-free cross-license under the patents-named in-the proceedings and their families allowing the manufacture and sale of OTREXUP™ (methotrexate) injection and RASUVO™ in and for the U.S. As a result, the $1,800,000 million of capitalized legal patent defense costs will continue to be amortized over the estimated useful life of the patents.

Accounting Policies [Abstract]
Investments	Investments All short-term and long-term investments are U.S. Treasury bills or U.S. Treasury notes that are classified as held-to-maturity because of the Company’s positive intent and ability to hold the securities to maturity. The securities are carried at their amortized cost and the fair value of all securities is determined by quoted market prices. At June 30, 2015 and December 31, 2014, the Company’s short-term investments had a carrying value of $6,001,895 and $6,002,438, respectively. As of June 30, 2015, the Company had long-term investments with a carrying value of $9,016,818, and held no long-term investments as of December 31, 2014. The carrying value of the Company’s short-term and long-term investments as of June 30, 2015 and December 31, 2014, approximated fair value.
Inventories	Inventories Inventories are stated at the lower of cost or market. Cost is determined on a first-in, first-out basis. Certain components of the Company’s products are provided by a limited number of vendors, and the Company’s production, assembly, warehousing and distribution operations are outsourced to third-parties where substantially all of the Company’s inventory is located. Disruption of supply from key vendors or third-party suppliers may have a material adverse impact on the Company’s operations. The Company provides reserves for potentially excess, dated or obsolete inventories based on an analysis of inventory on hand compared to forecasts of future sales. Inventories consist of the following: June 30, December 31, 2015 2014 Inventories: Raw material $ 388,499 $ 461,396 Work in process 3,243,499 3,896,837 Finished goods 1,833,570 1,501,691 $ 5,465,568 $ 5,859,924
Capitalized Patent Costs	Capitalized Patent Costs The Company capitalizes external legal patent defense costs and costs for pursuing patent infringements when it determines that a successful outcome is probable and will lead to an increase in the value of the patent. The capitalized costs are amortized over the remaining life of the related patent. If changes in the anticipated outcome were to occur that reduce the likelihood of a successful outcome of the entire action to less than probable, the capitalized costs would be charged to expense in the period in which the change is determined. As of June 30, 2015 and December 31, 2014, approximately $1,800,000 in external legal patent defense costs were capitalized within patent rights, net.
Product Revenue	Product Revenue In February 2014, the Company began detailing OTREXUP™ to health care professionals in the U.S. and began shipping to wholesale pharmaceutical distributors, subject to rights of return within a period beginning six months prior to, and ending 12 months following, product expiration. Given the limited sales history of OTREXUP™, the Company currently cannot reliably estimate expected returns of the product at the time of shipment. Accordingly, recognition of revenue is deferred on product shipments of OTREXUP™ until the right of return no longer exists, which occurs at the earlier of the time OTREXUP™ units are dispensed through patient prescriptions or expiration of the right of return. Units dispensed are generally not subject to return, except in the rare cases where the product malfunctions or the product is damaged in transit. Patient prescriptions dispensed are estimated using third-party market prescription data. These third-party sources poll pharmacies, hospitals, mail order and other retail outlets for OTREXUP™ prescriptions and project this sample on a national level. If patient prescriptions dispensed for a given period are underestimated or overestimated, adjustments to revenue may be necessary in future periods. The Company recognized $3,346,094 and $6,350,403 in OTREXUP™ product revenue for the three and six months ended June 30, 2015, respectively, as compared to $1,671,470 and $1,884,315 for the three and six months ended June 30, 2014, which is presented net of product allowances for estimated wholesaler discounts, prompt pay discounts, chargebacks, rebates and patient discount programs. The Company had deferred revenue balances of $986,517 and $1,061,947 at June 30, 2015 and December 31, 2014, respectively, for OTREXUP™ product shipments, which is net of product sales allowances. The Company will continue to recognize revenue upon the earlier to occur of prescription units dispensed or expiration of the right of return until it can reliably estimate product returns, at which time the Company will record a one-time increase in net revenue related to the recognition of revenue previously deferred. In addition, the costs of manufacturing OTREXUP™ associated with the deferred revenue are recorded as deferred costs, which are included in inventory, until such time as the related deferred revenue is recognized.
Product Sales Allowances	Product Sales Allowances The Company recognizes product sales allowances as a reduction of product sales in the same period the related revenue is recognized. Product sales allowances are based on amounts owed or to be claimed on the related sales. These estimates take into consideration the terms of our agreements with customers and third-party payors and the levels of inventory within the distribution channels that may result in future rebates or discounts taken. In certain cases, such as patient support programs, the Company recognizes the cost of patient discounts as a reduction of revenue based on estimated utilization. If actual future results vary, it may be necessary to adjust these estimates, which could have an effect on product revenue in the period of adjustment. Product sales allowances include: Wholesaler Distribution Fees Prompt Pay Discounts Chargebacks Rebates Patient Discount Programs
