     This Amendment No. 1 amends the Schedule 13D filed by Elan International
Services, Ltd., a Bermuda exempted company, with the Securities and Exchange
Commission on February 4, 1998 (the "Schedule 13D") relating to the Common
Stock, par value $.001 per share, of DOR BioPharma, Inc., a Delaware
corporation.

Item 1.  Security and Issuer.

     Item 1 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     The title of the class of securities to which this Schedule 13D relates is
the Common Stock, par value $.001 per share (the "Common Stock"), of DOR
BioPharma, Inc., a Delaware corporation (the "Issuer"). The name and address of
the principal executive offices of the Issuer is DOR BioPharma, Inc., 28101
Ballard Drive, Suite F, Lake Forest, Illinois 60045.

Item 2.  Identity and Background.

     Item 2 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     This Schedule 13D is filed by Elan International Services, Ltd., a Bermuda
exempted company ("EIS"), and Elan Pharmaceutical Investments, Ltd., a Bermuda
exempted company ("EPIL"). EPIL is a wholly owned subsidiary of EIS. EIS is a
wholly owned subsidiary of Elan Corporation, plc, an Irish public limited
company ("Elan").

     Schedule A to this Schedule 13D sets forth (1) with respect to each of
Elan, EIS and EPIL, (a) its name, (b) the state or other place of its
organization, (c) its principal business, (d) the address of its principal
business and (e) the address of its principal office and (2) with respect to
each executive officer and director of Elan, EIS and EPIL, his or her (a) name,
(b) residence or business address, (c) present principal occupation or
employment and the name, principal business and address of any corporation or
other organization in which such employment is conducted and (d) citizenship.

     During the last five years, none of Elan, EIS, EPIL or any other person
identified on Schedule A to this Schedule 13D: (i) has been convicted in a
criminal proceeding (excluding traffic violations or similar misdemeanors); or
(ii) was a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction, as a result of which proceeding it was or is subject to
a judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, United States federal or state securities
laws, or finding any violation with respect to such laws.

Item 3.  Source and Amount of Funds or Other Consideration

     Item 3 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     Pursuant to a securities purchase agreement dated January 21, 1998 between
EIS and the Issuer (the "First Securities Purchase Agreement"), EIS acquired (a)
307,692 shares of Common Stock, (b) 80,100 shares of Series B Convertible
Preferred Stock of the Issuer (the "Series B Preferred Stock") and (c) a warrant
to purchase up to 230,770 shares of Common Stock at an exercise price of $10.00
per share (the "Warrant") for aggregate consideration of $10,010,000, which was
provided by working capital of EIS. The Series B Preferred Stock accrues
cumulative pay-in-kind dividends at an annual rate of 8.0%, payable annually,
and is convertible into Common Stock at a conversion price of $7.38 per share.
As of May 22, 2002, the Series B Convertible Preferred Stock was convertible
into 1,516,404 shares of Common Stock.

     Pursuant to a securities purchase agreement dated October 21, 1998 between
EIS and the Issuer (the "Second Securities Purchase Agreement"), EIS acquired
84,105 shares of Series C Exchangeable Convertible Stock of the Issuer (the
"Series C Preferred Stock") for aggregate consideration of $8,410,500. The
Series C Preferred Stock accrues cumulative pay-in-kind dividends at an annual
rate of 7.0%, payable annually. The



                                  Page 4 of 15



Series C Preferred Stock is exchangeable for an additional 30.1% ownership
interest in Newco II (as defined in Item 4) or, alternatively, it is convertible
into Common Stock at a conversion price of $8.86 per share. As of May 22, 2002,
the Series C Exchangeable Convertible Preferred Stock was convertible into
1,211,043 shares of Common Stock. EIS also acquired a convertible promissory
note of the Issuer having a maximum aggregate principal amount of $4.806 million
(the "Convertible Note"). Disbursements under the Convertible Note accrue
cumulative pay-in-kind interest at an annual rate of 7.0%, compounded
semi-annually, and are convertible into Common Stock at a conversion price of
$5.70 per share. As of May 22, 2002, no disbursements had been made under the
Convertible Note (and no disbursements may be made under the Convertible Note
after December 31, 2001).

     In June 1999, EIS transferred to EPIL its right, title and interest to its
shares of Common Stock, Series B Preferred Stock and Series C Preferred Stock
and the Warrant.

Item 4. Purpose of Transaction.

     Item 4 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     In connection with the transactions described in the first paragraph of
Item 3, the Issuer and EIS established a new joint venture company ("Newco I"),
initially owned 80.1% by the Issuer and 19.9% by EIS. Newco I was initially
capitalized with $10,000,000, of which $8,010,000 was provided by the Issuer and
$1,990,000 was provided by EIS. Newco I was established principally for the
exclusive research, development and commercialization of oral and mucosal
prophylactic and therapeutic vaccines.

     In connection with the transactions described in the second paragraph of
Item 3, the Issuer and EIS agreed to establish a new joint venture company
("Newco II"), initially owned 80.1% by the Issuer and 19.9% by EIS. Newco II was
initially capitalized with $10,500,000, of which $8,410,500,000 was provided by
the Issuer and $2,089,500 was provided by EIS. Newco II was established
principally for the exclusive research, development and commercialization of
products using Elan's Medipad(TM) delivery system for two drugs in undisclosed
fields.

     Elan and EIS are currently in discussions with the Issuer with respect to
terminating the joint ventures relating to Newco I and Newco II. Any such
termination could involve one or more of the following: (a) the acquisition by
Elan, EIS or EPIL of additional securities of the Issuer, or the disposition of
securities of the Issuer; (b) an extraordinary corporate transaction such as a
merger, reorganization or liquidation, involving the Issuer or any of its
subsidiaries; (c) a sale or transfer of a material amount of assets of the
Issuer or any of its subsidiaries; (d) a change in the present board of
directors or management of the Issuer; (e) a material change in the present
capitalization of the Issuer; (f) other material changes in the Issuer's
business or corporate structure; and/or (g) changes in the Issuer's charter.

     On May 23, 2002, EPIL appointed Steve H. Kanzer as proxy for EPIL, with
full powers of substitution, to represent EPIL and to vote on behalf of EPIL all
shares of Common Stock and Series B Preferred Stock that EPIL is entitled to
vote at the Annual Meeting of Stockholders of the Issuer to be held at 10:00
A.M. on May 23, 2002, and any adjournments or postponements thereof (the "Annual
Meeting"), in the following manner: (1) with regard to the nomination and
election of directors, to vote such shares for the nominees named therein; (2)
to vote such shares in the proxy's discretion upon matters (i) incident to the
conduct of the Annual Meeting, including any adjournments or postponements
thereof or (ii) incident or appurtenant to or reasonably related to the election
of directors at the Annual Meeting; and (3) to vote for the ratification of the
independent auditors named therein. The purpose of the proxy, in part, is to
effect a change in the board of directors of the Issuer.

     Except as set forth in this Item 4 or elsewhere in this Schedule 13D, none
of Elan, EIS or EPIL has a plan or proposal which relates to or would result in:

     (a)  The acquisition by any person of additional securities of the Issuer,
          or the disposition of securities of the Issuer;

                                  Page 5 of 15


     (b)  An extraordinary corporate transaction such as a merger,
          reorganization or liquidation, involving the Issuer or any of its
          subsidiaries;

     (c)  A sale or transfer of a material amount of assets of the Issuer or any
          of its subsidiaries;

     (d)  Any change in the present board of directors or management of the
          Issuer, including any plans or proposals to change the number of or
          term of directors or to fill any existing vacancies on the board;

     (e)  Any material change in the present capitalization or dividend policy
          of the Issuer;

     (f)  Any other material change in the Issuer's business or corporate
          structure;

     (g)  Changes in the Issuer's charter, bylaws or instruments corresponding
          thereto or other actions which may impede the acquisition of control
          of the Issuer by any person;

     (h)  Causing a class of securities of the Issuer to be delisted from a
          national securities exchange or cease to be authorized to be quoted in
          an inter-dealer quotation system of a registered national securities
          association;

     (i)  A class of equity securities of the Issuer becoming eligible for
          termination of registration pursuant to Section 12(g)(4) of the Act;
          or

     (j)  Any action similar to any of those enumerated above.

Item 5.  Interest in Securities of Issuer.

     Item 5 of the Schedule 13D is hereby amended and restated in its entirety
as follows:

     (a) As of May 22, 2002, EIS (indirectly through its ownership of EPIL) and
EPIL each beneficially owned 3,222,809 shares of Common Stock (including (a)

upon conversion of the Series B Convertible Preferred Stock, (b) 230,770 shares
of Common Stock issuable upon exercise of the Warrant and (c) 1,211,043 shares
of Common Stock issuable upon conversion of the Series C Convertible Preferred
Stock).

     (c) None.
