Item 1.    Security and Issuer.

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

     This Amendment No. 1 is filed by Elan Corporation, plc, an Irish public
limited company ("Elan"), and Elan's direct wholly-owned subsidiary, Elan
International Services, Ltd., a Bermuda exempted company ("EIS"), and relates to
the common stock, par value $.01 per share (the "Common Stock"), of Iomed, Inc.,
a Delaware corporation ("Issuer"). This Amendment No. 1 amends the Schedule 13D
with the Securities and Exchange Commission (the "Commission") on May 19, 1998
(the "Schedule 13D"). The name and address of the principal executive offices of
the Issuer is Iomed, Inc., 3385 West 1820 South, Salt Lake City, Utah 84104.

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 and EIS, in respect of Common Stock
beneficially owned directly by EIS.

     Elan's principal place of business is Lincoln House, Lincoln Place, Dublin
2, Ireland. Elan is a worldwide biopharmaceutical company. EIS's principal place
of business is 102 St. James Court, Flatts, Smiths, FL 04 Bermuda. EIS is an
investment holding company.

     Schedule A to this Schedule 13D sets forth the (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 or place of organization of
each executive officer, director and controlling person of Elan and EIS.

     During the last five years, neither Elan, EIS nor any 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:

     Concurrent with the closing of the IPO ( as defined below), EIS acquired an
aggregate of 2,100,192 shares stock of the Issuer, consisting of 1,206,391
shares of common stock, no par value (the "Common Stock"), and 893,801 shares of
Series D Non-Voting Convertible Preferred Stock, for aggregate consideration of
$15,751,438.41, which was provided by EIS's general corporate funds.

Item 4. Purpose of Transaction.

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



                                  Page 4 of 10


     In connection with a licensing and financing transaction consummated on
April 14, 1997, the Issuer issued promissory notes, in the original principal
amounts of $10,000,000 and $5,000,000 (respectively, the "A Note" and the "B
Note"; collectively, the "Notes") to Elan International Management, Ltd.
("EIM"). Under the terms of a note purchase agreement by and among the Issuer,
EIS and EIM (the "NPA"), pursuant to which the Notes were issued and sold, upon
consummation of an initial public offering of Common Stock of the Issuer (an
"IPO"), the Issuer was to repay the all principal and accrued interest on the
Notes in full, and EIS was to subscribe for an amount of shares of Common Stock
equal to the quotient obtained by dividing (i) the sum of principal and accrued
interest on the Notes (i.e., $15,751,438.41) by (ii) the IPO price of Common
Stock.

     Pursuant to an amendment to the NPA dated April 24, 1998 (the "Amendment"),
the Issuer repaid all outstanding principal and interest on the Notes, and EIS
subscribed for 1,206,391 shares of Common Stock and 893,801 shares of a newly
created series of non-voting, convertible preferred stock.

     In addition, pursuant to the terms of the NPA, EIS received a five-year
warrant to purchase Common Stock (the "Warrant"), which permitted EIS to
purchase (post a reverse stock split) up to 104,167 shares at an exercise price
of $21.60 per share. The Warrant has expired in accordance with its terms.

     The Issuer has granted certain demand and piggyback registration rights in
respect of the Common Stock owned by EIS, including the Common Stock issuable
upon conversion of the Series D Preferred Stock..

     The NPA provides that, for so long as EIS and its affiliates are the
beneficial owners of at least 10% of the Common Stock on a fully diluted basis
(including the Common Stock issuable upon conversion of the Series D Preferred
Stock but not upon exercise of options), the Issuer shall use its best efforts
to cause EIS to designate one member of the Issuer's Board of Directors.

     EIS intends to sell shares of the Common Stock from time to time in open
market transactions, subject to market conditions any restrictions, including
volume restrictions, imposed under applicable securities laws. EIS expects to
evaluate its investment in the Issuer on an ongoing basis and EIS may determine
to change its investment intent with respect to the Issuer at any time in the
future. In determining from time to time whether to sell or to retain its
holdings of securities of the Issuer, EIS will take into consideration such
factors as it deems relevant, including the market price of the Common Stock,
conditions in the securities markets generally, the Issuer's financial
condition, business and prospects and general economic conditions. Subject to
any restrictions imposed under applicable securities law, EIS reserves the right
to dispose of all or a portion of its holdings of securities of the Issuer in
public or private transactions and/or to enter into privately negotiated
derivative transactions with institutional counterparties to hedge the market
risk of some or all of its positions in the securities of the Issuer. Any such
transaction may be effected at any time or from time to time.

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 June 25, 2004, Elan (indirectly through its ownership of EIS) and
EIS each beneficially own 1,862,492 shares of Common Stock (including 893,801
shares issuable upon conversion of the Series D Preferred Stock), representing
24.9% of the outstanding shares of Common Stock (based on 6,575,794 shares of
Common Stock outstanding as of April 30, 2004 as reported in the Issuer's Form
10-Q for the quarterly period ended March 31, 2004).



                                  Page 5 of 10


     (b) As of June 25, 2004, Elan (indirectly through its ownership of EIS) and
