Item 1.   Security and Issuer.

     Item 1 is amended to read in its entirety as follows:

     "This Statement  covers a total of 18,533,099  shares of Common Stock,  par
value $.01 per share (the "Common Stock"),  of Halsey Drug Co., Inc., a New York
corporation  (the  "Company").  As of July 17,  1998 the  Reporting  Persons (as
defined in Item 2 hereof) hold (i) 5% Convertible  Senior Secured Debentures due
March 15, 2003, of the Company in the aggregate  principal amount of $21,334,616
(the  "Debentures"),  which as of such date are convertible into an aggregate of
14,223,078  shares  of  Common  Stock,  (ii)  warrants  for the  purchase  of an
aggregate of 2,155,011  shares of Common Stock at an initial  purchase  price of
$1.50 per share (the "$1.50 Warrants") and (iii) warrants for the purchase of an
aggregate of 2,155,011  shares of Common Stock at an initial  purchase  price of
$2.375 per share (the "$2.375  Warrants" and together  with the $1.50  Warrants,
the   "Warrants").   The   Debentures  and  Warrants  are  referred  to  herein,
collectively, as the "Securities."

     The  Company's  principal  executive  offices are  located at 1827  Pacific
Street, Brooklyn, New York 11233."


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

     Item 3 is amended to read in its entirety as follows:

     "The funds for the  acquisition of the  Securities  were allocated from the
working  capital of the  Reporting  Persons and were not  obtained by means of a
loan or other borrowing arrangement.

     The Securities  were acquired by the Reporting  Persons at a purchase price
equal to the principal amount of Debentures  comprising a part of the Securities
which were purchased.  The purchase prices paid by each of Galen, Galen Intl and
GEF  on  March  10,  1998  for  the  Securities  purchased  on  such  date  were
$15,423,195, $1,709,167 and $67,638, respectively, and were all paid in cash.

     In June, 1998 the Reporting Persons made additional purchases of Securities
for cash  pursuant to the option  granted to them under the  Purchase  Agreement
described  in Item 4 hereof to  purchase  additional  Securities.  The  purchase
prices for the additional  Securities  purchased by Galen, Galen Intl and GEF in
June, 1998 were $3,754,809, $363,369 and $16,438, respectively.

     In July 1998 Galen  International sold to Galen and GEF for a cash purchase
price  (a)   Debentures  in  the   principal   amounts  of  $196,809  and  $745,
respectively,  (b) $1.50  Warrants  to  purchase  19,880 and 75 shares of Common
Stock,  respectively and (c) $2.375 Warrants to purchase 19,880 and 75 shares of
Common Stock, respectively."


Item 4.   Purpose of Transaction.

     Item 4 is amended to read in its entirety as follows:

     "The Company,  the Reporting Persons and certain other persons entered into
a Debenture  and  Warrant  Purchase  Agreement,  dated as of March 10, 1998 (the
"Purchase  Agreement")  providing for the purchase by the Reporting  Persons and
other persons  (collectively,  the  "Investors")  of an aggregate of $20,800,000
principal  amount of  Debentures,  $1.50  Warrants to purchase an  aggregate  of
2,101,010 shares of Common Stock and $2.375 Warrants to purchase an aggregate of
2,101,010 shares of Common

                                        5





Stock and the issuance and delivery to the Investors of  instruments  evidencing
the  Debentures  and  Warrants.  The  Debentures  were at the  time of  issuance
convertible  into Common Stock at the rate of one share of Common Stock for each
$1.50  principal  amount of Debentures  (an  aggregate of  13,866,666  shares of
Common Stock for the Debentures issued to all Investors and 11,466,667 shares of
Common Stock for the  Debentures  issued to the  Reporting  Persons).  The $1.50
Warrants and $2.375 Warrants issued to the Reporting Persons are exercisable for
a period of seven years commencing on the issue date thereof.

     In June 1998,  the Reporting  Persons and certain  other persons  exercised
their  options  under the  Purchase  Agreement  to  purchase  a rata  portion of
additional  Securities  having an aggregate  purchase price of $5,000,000 on the
same terms and  conditions as set forth in the Purchase  Agreement.  Pursuant to
such  option  exercise,  the  Reporting  Persons  purchased  Debentures  in  the
aggregate  principal amount of $4,134,616  (which Debentures were at the time of
issuance  convertible into an aggregate of 2,756,411 shares of Common Stock) and
$1.50  Warrants to purchase an aggregate  of 417,637  shares of Common Stock and
$2.375 Warrants to purchase an aggregate of 417,637 of Common Stock.

     The conversion  rates of the Debentures  into Common Stock and the exercise
prices of the Warrants and the number of shares of Common  Stock  issuable  upon
conversion or exercise  thereof are subject to adjustment to protect the holders
thereof against dilution. In addition,  the conversion rates and exercise prices
of such  Securities  are  subject  to a  downward  adjustment  in the  event the
liabilities of the Company and its  subsidiaries  as of February 28, 1998 exceed
$27,640,000.

     Pursuant to the Purchase Agreement,  the Purchasers  designated two persons
to become directors of the Company and such persons were elected as directors on
March 10, 1998.  The  Purchasers  also had the right to designate an  additional
person to be a member of the Board of Directors commencing with the first Annual
Meeting of  Shareholders  of the  Company  to be held  after the  closing of the
Purchase  Agreement,  which the Company agreed in the Purchase Agreement to hold
on or prior to June 30, 1998 (the "Next Shareholders Meeting").

     The Company also agreed in the  Purchase  Agreement to present for approval
by  shareholders  at the Next  Shareholders  Meeting,  proposals  to  amend  the
Company's  Certificate  of  Incorporation  to increase the number of  authorized
shares of Common Stock from 20,000,000 to 40,000,000  Shares and to provide that
the  Debentures  shall have the right to vote as part of a single class with all
holders  of Common  Stock of the  Company  on all  matters  with the  holders of
Debentures  to have such number of votes as shall equal the number of votes they
would have had they converted the entire  principal  amount of their  Debentures
into Common Stock immediately prior to the record date relating to such vote.

     The Next  Shareholders  Meeting was duly held on June 30, 1998. At the Next
Shareholders  Meeting, a designee of the Purchasers was elected as a director of
the Company and the proposals to amend the Certificate of  Incorporation  of the
Company were approved by the shareholders.

     Pursuant to the Purchase  Agreement each Investor,  including the Reporting
Persons,  has  been  given  a  right  of  first  refusal,   subject  to  certain
limitations,  to purchase additional equity securities of the Company (including
convertible  debt  securities)  offered for sale by the  Company.  Such right is
exercisable  on a pro rata basis among all  Investors  and certain other persons
holding other convertible debentures of the Company.

     Each  of  the  Reporting  Persons  acquired  its  Securities  as  long-term
investments. Except as set forth herein, none of the Reporting Persons presently
intends to acquire additional securities of the

                                        6






Company.  However,  if any Reporting Person believes that further  investment in
the Company is attractive,  whether because of the market price of the Company's
securities or otherwise, such Reporting Person may acquire additional securities
of the Company.  Similarly,  any Reporting Person, subject to applicable law and
depending  upon market and other  factors,  may from time to time  determine  to
dispose some or all of the Securities.

     Except as set forth herein, the Reporting Persons have no present intention
to  engage  or  cause  the  Company  to  engage  in any of the  transactions  or
activities  specified in  paragraphs  (a) through (j) of Item 4 of Schedule 13D.
However,  each  Reporting  Person  reserves the right,  either  individually  or
together with other persons, to act in respect of its interest in the Company in
accordance with its best judgment in light of the circumstances existing at that
time."


Item 5.   Interest in Securities of the Issuer.

     Item 5 is amended to read in its entirety as follows:

     "(a) Each  Reporting  Person owns or has the right to acquire the number of
Securities shown opposite its name:
