Prospectus Supplement No. 1

                              Antares Pharma, Inc.

                        3,555,556 Shares of Common Stock

         This prospectus supplement supplements the prospectus dated October 10,
2002 of Antares Pharma, Inc. relating to the sale by certain of our shareholders
(including their pledgees, donees, assignees, transferees, successors and others
who later hold any of the shareholders' interests) of the shares of our common
stock issuable upon conversion of our 10% Secured Convertible Debentures. You
should read this prospectus supplement in conjunction with the prospectus, and
this prospectus supplement is qualified by reference to the prospectus, except
to the extent that the information in this prospectus supplement supercedes the
information contained in the prospectus.

                                  RECENT EVENTS

         On February 7, 2003, we completed a restructuring of our outstanding
10% Secured Convertible Debentures. As part of this restructuring, Xmark Fund,
LP and Xmark Fund, Ltd. loaned us $621,024.92, which we used to repurchase the
aggregate outstanding principal amount of such debentures previously sold to AJW
Partners, LLC, AJW Offshore, Ltd., AJW Qualified Partners, LLC and OTATO Limited
Partnership, including accrued interest and a repurchase premium. As a result,
the 10% debentures previously issued to each of the AJW entities and OTATO no
longer remain outstanding.

         Additionally, in exchange for the surrender by Xmark Fund, LP, Xmark
Fund, Ltd. and SDS Merchant Fund, LP of their 10% debentures, we also issued to
each of them our Amended and Restated 8% Senior Secured Convertible Debentures
in the aggregate principal amount of $992,230.37. The 8% debentures contain
substantially the same terms as the 10% debentures, except that they include a
fixed conversion price of $.50 per share and accrue interest at a rate of 8% per
annum. As a result of our repurchase and exchange of the 10% debentures and our
issuance of the 8% debentures, we are amending the Selling Shareholder
information in the prospectus.

         We also issued 8% Senior Secured Convertible Debentures to the Xmark
funds in exchange for the cancellation by the funds of the promissory note we
issued to them in connection with the money they loaned us to repurchase the 10%
debentures referred to above. These debentures contain identical terms to the 8%
debentures referred to above. Finally, in connection with these transactions, we
issued warrants to purchase an aggregate of 2,932,500 shares of our common stock
to the Xmark funds and SDS. We intend to separately register the shares of our
common stock issuable upon conversion of the new 8% debentures and exercise of
the warrants.

         We previously registered for resale an aggregate of 3,555,556 shares of
our common stock issuable upon conversion of the 10% debentures. Prior to the
restructuring transaction discussed above, the holders of the debentures
converted a portion of the principal amount thereof into 1,646,116 shares of our
common stock, of which 1,574,305 shares were sold pursuant to the prospectus.
Thus, the number of registered shares remaining for resale under the original
prospectus is 1,981,251.

         The information contained in the prospectus under the heading, "Selling
Shareholders," is hereby amended as follows:



                              SELLING SHAREHOLDERS

         The information contained in the prospectus under the heading, "Certain

               CERTAIN INFORMATION ABOUT THE SELLING SHAREHOLDERS

         The number of shares set forth in the table for the selling
shareholders represents the number of shares of our common stock issuable upon
conversion of the 8% debentures, assuming a $.50 per share conversion price. In
addition, the actual number of shares of common stock offered in this prospectus
supplement, and included in the registration statement of which the prospectus
was originally a part, includes such additional number of shares of common stock
as may be issued or issuable upon conversion of the 8% debentures by reason of
any stock split, stock dividend or similar transaction involving the common
stock, in accordance with Rule 416 under the Securities Act of 1933, as amended.


         Under the terms of the 8% debentures, the 8% debentures are convertible
by any holder only to the extent that the number of shares of common stock
issuable pursuant to such securities, together with the number of shares of
common stock owned by such holder and its affiliates (but not including shares
of common stock underlying unconverted shares of debentures) would not exceed
9.99% of the then outstanding common stock as determined in accordance with
Section 13(d) of the Exchange Act.

         Investing in the shares of common stock involves risks that are
described in the "Risk Factors" section beginning on page 2 of the prospectus.

         Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of these securities or determined if this
prospectus supplement is truthful or complete. Any representation to the
contrary is a criminal offense.
