Exhibit 99.2

         September 13, 2004, Investor Frequently Asked Questions and Answers

         From time to time, Investor Relations will provide FAQs on various
         topics of interest to investors. The following is a compilation of
         frequently asked questions and answers related to the alliance with
         Bayer.

Q        On September 13, Schering-Plough announced it entered into a strategic
         alliance with Bayer. Is this a merger between Schering-Plough and
         Bayer?

A        No. Schering-Plough and Bayer will remain independent companies. This
         alliance signifies a creative, new approach to industry collaborations
         and is designed to maximize the companies' pharmaceutical resources and
         build value while maintaining each company's own strategic interests.

Q        Why did Schering-Plough enter into a strategic alliance with Bayer?
         What are the general terms of the deal?

A        On Sept. 13, Schering-Plough announced that it has entered into a
         strategic alliance with Bayer involving Bayer's U.S. pharmaceutical
         business and a Zetia collaboration in Japan. This alliance with Bayer
         accomplishes three things for Schering-Plough:

         1) The alliance allows Schering-Plough to leverage and enhance its
         primary care infrastructure in the U.S. and Puerto Rico by increasing
         the number of product offerings to physicians and patients, including
         AVELOX, CIPRO and LEVITRA. In addition, a substantial number of
         high-performing Bayer sales representatives and marketing personnel are
         expected to be integrated into Schering-Plough.

         2) In Japan, the alliance with Bayer gives Schering-Plough a strong
         partner with deep expertise in cardiovascular disease to co-market
         ZETIA, Schering-Plough's novel cholesterol absorption inhibitor, upon
         local approval.

         3) Through the alliance, Schering-Plough will gain additional support
         for promotion of certain oncology products in the U.S. and key European
         markets.

Q        What are the financial terms of the agreement?

A        Under the terms of the strategic alliance, Schering-Plough will record
         U.S. sales of Bayer's primary care products, excluding LEVITRA.
         Schering-Plough will pay a substantial royalty to Bayer based on U.S.
         net sales of these products.

         Schering-Plough will co-promote LEVITRA with GlaxoSmithKline PLC in the
         U.S. Schering-Plough and Bayer will share Bayer's portion of the
         profits on the U.S. sales of LEVITRA.

         In Japan, Zetia profits will be shared by the two companies.



Q        Are there any one-time costs to Schering-Plough?

A        Under the agreement, there will be a business integration and
         transition period during the remainder of 2004. As a result, there may
         be some integration and transition costs, primarily in 2004.

         For Schering-Plough, the transaction is expected to be mildly dilutive
         in 2004, in terms of its impact on earnings per share (EPS). While the
         agreement is principally strategically driven, as such the transaction
         is expected to be mildly accretive after 2004.

Q        What is the likely impact of this strategic alliance on your income
         statement?

A        The terms of the alliance are expected to be effective on October 1,
         2004. Once effective, Schering-Plough will record its share of LEVITRA
         profits as alliance revenue.

         Schering-Plough will record U.S. net sales of Bayer's primary care
         products, excluding LEVITRA.

         Bayer will continue to manufacture these products and Schering-Plough
         will pay a substantial royalty to Bayer (expensed in the "Cost of
         Goods" line) based on U.S. net sales of these primary care products.
         The royalty rate paid to Bayer will decrease as sales exceed
         predetermined levels.

         As a result of the planned integration of a substantial number of
         Bayer's high-performing sales representatives and marketing personnel
         into Schering-Plough, Schering-Plough's "Selling, General &
         Administrative" expense line will reflect the increase in size of its
         primary care sales force.

         For Schering-Plough, the transaction is expected to be mildly dilutive
         in 2004, in terms of its impact on earnings per share (EPS). While the
         agreement is principally strategically driven, as such the transaction
         is expected to be mildly accretive after 2004.




Q        How will Schering-Plough's recent in-licensing of garenoxacin from
         Toyama be affected by this collaboration?

A        The agreement with Bayer potentially restricts Schering-Plough from
         marketing products in the United States that would compete with Bayer's
         quinolone antibiotic AVELOX.

         As previously announced on June 22, 2004, Schering-Plough and Toyama
         Chemical Co. Ltd. entered into a definitive licensing agreement for
         garenoxacin, Toyama's proprietary quinolone antibacterial agent.

         As a result of the agreement with Bayer, Schering-Plough expects it may
         need to sublicense rights to the Toyama product in the United States.
         The company is exploring its options with regard to garenoxacin and
         will continue to fulfill its commitments to Toyama under its
         arrangement, including taking the product through regulatory approval.

Q        How does this collaboration affect Schering-Plough's PDE-5 inhibitor in
         early phase development for the treatment for erectile dysfunction?

A        The agreement with Bayer potentially restricts Schering-Plough from
         marketing products in the United States that would compete with the
         erectile dysfunction product LEVITRA. If approved, Schering-Plough's
         PDE-5 inhibitor would be a direct competitor to LEVITRA.

         As a result of the agreement with Bayer, Schering-Plough expects it may
         need to out license U.S. rights to its PDE-5 inhibitor for the
         treatment of erectile dysfunction.

Q        Why did you choose Bayer as a partner for Zetia in Japan? Does the
         agreement include the development of a combination cholesterol product
         in Japan?

A        In Japan, Bayer is a leading international pharmaceutical company, with
         a well-recognized expertise in cardiovascular therapy. Bayer has
         demonstrated skill and competence in the hyperlipidemia therapeutic
         area and Schering-Plough believes that Bayer will be able to help make
         Zetia a successful first-line monotherapy as well as add-on therapy for
         the treatment of high cholesterol in Japan.

         This alliance does not cover the commercialization of a combination
         product in Japan. Schering-Plough retains those rights exclusively.







Q        What is the status of ZETIA in Japan?

A        Following a filing in the fourth quarter of 2003, Zetia is under
         regulatory review in Japan.

Q        Will Bayer share in the profits/revenues of the Schering-Plough
         oncology products that they will promote in the U.S. and key European
         markets?

A        No. Schering-Plough will continue to book all sales and profits from
         its oncology products.
