Report of Independent Registered Public

To the Shareholders and Board of Directors

of Dr. Reddy's Laboratories Limited

Results of Review of Interim Financial

We have reviewed the accompanying condensed

consolidated statement of financial position of Dr. Reddy's Laboratories Limited and subsidiaries (the Company) as of September

30, 2021, the related condensed consolidated interim income statements and statements of comprehensive income for the three and

six-month periods ended September 30, 2021 and 2020, the statements of changes in equity and cash flows for the six-month periods

ended September 30, 2021 and 2020, and the related notes (collectively referred to as the "condensed consolidated interim

financial statements"). Based on our reviews, we are not aware of any material modifications that should be made to the condensed

consolidated interim financial statements for them to be in conformity with International Accounting Standard (IAS) 34, Interim

Financial Reporting as issued by the International Accounting Standards Board.

We have previously audited, in accordance

with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statement of financial

position of the Company as of March 31, 2021, the related consolidated income statements, statements of comprehensive income, shareholders'

equity and cash flows for the year then ended, and the related notes and schedules (not presented herein); and in our report dated

June 30, 2021, we expressed an unqualified audit opinion on those consolidated financial statements. In our opinion, the information

set forth in the accompanying condensed consolidated balance sheet as of March 31, 2021, is fairly stated, in all material respects,

in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

These financial statements are the responsibility

of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with

respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the SEC

and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial statements

consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting

matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective

of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such
