Item 1. Security and Issuer.

     This statement on Schedule 13D relates to the Common Stock, par value $0.01
per share ("Sicor Common Stock"), of Sicor Inc., a Delaware corporation
("Sicor"), and is being filed pursuant to Rule 13d-1 under the Securities
Exchange Act of 1933, as amended (the "Exchange Act"). The principal executive
offices of Sicor are located at 19 Hughes, Irvine, California 92618.

Item 2. Identity and Background.

     This statement is filed on behalf of Teva Pharmaceutical Industries
Limited, an Israeli corporation ("Teva"). The address of the principal business
and principal office of Teva is 5 Basel Street, P.O. Box 3190, Petach Tikva
49131, Israel. The principal business of Teva is developing, manufacturing and
marketing generic and innovative human pharmaceuticals and active pharmaceutical
ingredients.

     The names, residence or business address, citizenships and present
principal occupations or employment of the executive officers and directors of
Teva are set forth in Annex A hereto.

     During the last five years, neither Teva nor, to the best knowledge of
Teva, any person named in Annex A, has been (i) convicted in a criminal
proceeding (excluding traffic violations or similar misdemeanors) or (ii) a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment,
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or finding any
violations with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

     Sicor, Teva and Silicon Acquisition Sub, Inc., a Delaware corporation and a
wholly owned subsidiary of Teva ("Merger Sub"), have entered into an Agreement
and Plan of Merger, dated as of October 31, 2003 (the "Merger Agreement"),
providing for the merger of Merger Sub with and into Sicor (the "Merger"), with
Sicor surviving the Merger as a wholly owned subsidiary of Teva. Pursuant to the
Merger Agreement, each share of Sicor Common Stock will be exchanged in the
Merger for the right to


                                    3 of 12




receive $16.50 in cash and 0.1906 ordinary shares, par value NIS 0.10 per share,
of Teva, which will trade in the United States in the form of American
Depositary Shares evidenced by American Depositary Receipts, plus cash in lieu
of fractional shares, subject to adjustment as provided in the Merger Agreement.
It is currently expected that the cash consideration paid by Teva to the holders
of Sicor Common Stock pursuant to the Merger Agreement will be financed by Teva
through available working capital and other available sources of liquidity which
may include bank loans.

     Concurrently with the execution and delivery of the Merger Agreement, Teva
entered into a Stockholders Agreement, dated as of October 31, 2003 (the
"Stockholders Agreement"), with those stockholders of Sicor listed therein (the
"Sicor Stockholders"). Pursuant to the Stockholders Agreement, the Sicor
Stockholders have agreed that until the termination of the Stockholders
Agreement, the Sicor Stockholders will vote or cause to be voted the shares of
Sicor Common Stock over which the Sicor Stockholders have voting power in favor
of the approval and adoption of the Merger Agreement and the Merger (as more
fully described in Item 6).

     The descriptions of the Merger Agreement and the Stockholders Agreement
contained in this Schedule 13D are qualified in their entirety by reference to
such agreements, which are incorporated by reference as Exhibits 1 and 2 hereto,
respectively.

Item 4. Purpose of Transaction.

     The Sicor Stockholders agreed to enter into the Stockholders Agreement to
induce Teva, Merger Sub and Sicor to enter into the Merger Agreement and to
consummate the transactions contemplated by the Merger Agreement, including
without limitation the Merger.

     Other than pursuant to the Merger Agreement as described above, neither
Teva nor, to the best knowledge of Teva, any person listed in Annex A hereto,
has any plans or proposals which relate to or would result in: (a) the
acquisition by any person of additional securities of Sicor, or the disposition
of securities of Sicor; (b) an extraordinary corporate transaction, such as a
merger, reorganization or liquidation, involving Sicor


                                    4 of 12




or any of its subsidiaries; (c) a sale or transfer of a material amount of
assets of Sicor or any of its subsidiaries; (d) any change in the present Board
of Directors or management of Sicor, including any plans or proposals to change
the number 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
Sicor; (f) any other material change in Sicor's business or corporate structure;
(g) changes in Sicor's charter, By-Laws or instruments corresponding thereto or
other actions which may impede the acquisition of control of Sicor by any
person; (h) causing a class of securities of Sicor to be delisted from a
national securities exchange or to 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 Sicor becoming eligible for termination of
registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any action
similar to any of those enumerated above (although the Teva reserves the right
to develop such plans).

Item 5. Interest in Securities of the Issuer.

(a) and (b). As of October 31, 2003, 22,373,114 shares of Sicor Common Stock,
including 437,406 shares subject to warrants or options that are exercisable
within 60 days of October 31, 2003, were subject to the Stockholders Agreement,
the "Stockholders Agreement Shares"). The Stockholders Agreement Shares
represent approximately 18.7% of the issued and outstanding shares of Sicor
Common Stock as of October 31, 2003, as represented by Sicor in the Merger
Agreement. By virtue of the Stockholders Agreement, Teva may be deemed to share
with the Sicor Stockholders the power to vote or direct the voting of the
Stockholders Agreement Shares. However, Teva is not entitled to any other rights
as a stockholder of Sicor as to the Stockholders Agreement Shares, and does not
have any right to dispose or direct the disposition of the Stockholders
Agreement Shares, except for the restrictions described in Item 6.

     Pursuant to Rule 13d-4 under the Exchange Act, Teva hereby states that this
Schedule 13D shall not be deemed an admission that Teva is, for the purposes of
Section 13(d) of the Exchange Act, the beneficial owner of any equity securities
of Sicor, and Teva expressly disclaims beneficial ownership of the Stockholders
Agreement Shares.


                                    5 of 12




     To the best knowledge of Teva, no shares of Sicor Common Stock are
beneficially owned by any of the persons named in Annex A.

(c). Neither Teva, nor, to the best knowledge of Teva, any person named in Annex
A, has effected any transaction in Sicor Common Stock during the past 60 days.

(d) and (e). Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
        Securities of the Issuer.

     Pursuant to the Stockholders Agreement, and subject to the terms and
conditions contained therein, each Sicor Stockholder has agreed that prior to
the termination of the Stockholders Agreement, at any meeting of the
stockholders of Sicor called to vote upon the Merger Agreement, the Merger or
any other transactions (the "Transactions") contemplated by the Stockholders
Agreement and the Merger Agreement, or at any adjournment or postponement
thereof, or in any other circumstances upon which a vote, consent, adoption or
other approval (including by written consent solicitation) with respect to the
Merger Agreement, the Merger or any other Transactions is sought, such Sicor
Stockholder will vote (or cause to be voted) all of the Stockholder Agreement
Shares of such Sicor Stockholder and any other Subject Shares (as defined in the
Stockholders Agreement) then owned of record and beneficially by such Sicor
Stockholder in favor of the adoption of the Merger Agreement and the approval of
the terms thereof and of the Merger and each of the other Transactions.

     Pursuant to the Stockholders Agreement, and subject to the terms and
conditions contained therein, each Sicor Stockholder has also agreed that prior
to the termination of the Stockholders Agreement, at any meeting of the
stockholders of the Sicor or at any adjournment or postponement thereof or in
any other circumstances upon which a vote, consent, adoption or other approval
is sought, such Sicor Stockholder shall vote (or cause to be voted) all of the
Stockholder Agreement Shares of such Sicor Stockholder and any other Subject
Shares then owned of record and beneficially by such Sicor Stockholder against,
and


                                    6 of 12




shall not consent in writing to (and shall cause not to be consented in writing
to), any of the following (or any agreement to enter into, effect, facilitate or
support any of the following): (i) any Acquisition Proposal (as defined in the
Stockholders Agreement) or transaction or occurrence that if proposed and
offered to Sicor or its stockholders (or any of them) would constitute an
Acquisition Proposal or (ii) any amendment of Sicor's certificate of
incorporation, Sicor's by-laws or the Sicor Stockholder Rights Plan (as defined
in the Stockholders Agreement) or other proposal, action or transaction
involving Sicor or any of its stockholders, which amendment or other proposal,
action or transaction would reasonably be expected to prevent or materially
impede or delay the consummation of the Merger or the other Transactions or
change in any manner the voting rights of the Sicor Common Stock.

     Furthermore, except as provided for in the Stockholders Agreement, each
Sicor Stockholder, pursuant to the Stockholders Agreement, and subject to the
terms and conditions contained there, has irrevocably granted to and appointed
certain designees of Teva such Sicor Stockholder's proxy and attorney-in-fact
(with full power of substitution), for and in the name, place and stead of such
Stockholder, to vote all of such Sicor Stockholder's Subject Shares (owned of
record) in accordance with the provisions described above.

     Also pursuant to the Stockholders Agreement, and subject to the terms and
conditions contained therein, each Sicor Stockholder has agreed that until the
termination of the Stockholders Agreement, except for the Stockholders
Agreement, such Sicor Stockholder shall not (i) sell, transfer, pledge, assign
or otherwise dispose of (including by gift) (collectively, "Transfer") or enter
into any contract, option or other arrangement (including any profit sharing
arrangement) with respect to the Transfer of, or the creation or offer of any
derivative security in respect of, any Subject Shares or Share Acquisition
Rights (as defined in the Stockholders Agreement), to or with any person other
than pursuant to the Merger or (ii) enter into any voting arrangement, whether
by proxy, voting agreement or otherwise, with respect to any Subject Shares or
Share Acquisition Rights, and shall not commit or agree to take any of the
foregoing actions.


                                    7 of 12




     Except as referred to above, there are no contracts, arrangements,
understandings or relationships among the persons named in Item 2 or between
such persons and any other person with respect to any securities of Sicor.
