	KNOW ALL BY THESE PRESENTS, that the undersigned hereby constitutes and
appoints Edward M. Kaye MD, Sandesh Mahatme, and David Tyronne Howton, and their
respective successors, and each of them her true and lawful attorney-in-fact and
agent with full power of substitution, signing singly, for her and in her name,
place and stead, in any and all capacities, to:

1.	prepare, execute in the undersigned's name and on the undersigned's behalf,
and submit to the U.S. Securities and Exchange Commission (the "SEC") a Form ID,
including amendments thereto, and any other documents necessary or appropriate
to obtain codes and passwords enabling the undersigned to make electronic

Securities Exchange Act of 1934 (as amended, the "Exchange Act") or any rule or
regulation of the SEC;

2.	complete and execute for and on behalf of the undersigned, in the
undersigned's capacity as an officer and/or director of Sarepta Therapeutics,
Inc. (the "Company") and/or 10% holder of the Company's capital stock, Forms 3,
4, 5 and Form ID, any other forms, and any amendments thereto in accordance with
Section 16(a) of the Exchange Act and the rules and regulations thereunder;

3.	do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete and execute any such Form 3, 4, 5 or
Form ID, or any other forms,  complete and execute any amendment or amendments
thereto, and timely file such form with the SEC and any stock exchange or
similar authority; and

4.	take any other action of any type whatsoever in connection with the foregoing
which, in the opinion of such attorney-in-fact, may be of benefit to, in the
best interest of, or legally required by, the undersigned, it being understood
that the documents executed by such attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and
shall contain such terms and conditions as such attorney-in-fact may approve in
such attorney-in-fact's discretion.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or
revocation, hereby ratifying and confirming all that such attorney-in-fact, or
such attorney-in-fact's substitute or substitutes, shall lawfully do or cause to
be done by virtue of this power of attorney and the rights and powers herein
granted.  The undersigned acknowledges that the foregoing attorneys-in-fact, in
serving in such capacity at the request of the undersigned, are
not assuming, nor is the Company assuming, any of the undersigned's
responsibilities to comply with Section 16 of the Exchange Act.

The undersigned agrees that each such attorney-in-fact herein may rely entirely
on information furnished orally or in writing by the undersigned to such
attorney-in-fact.  The undersigned also agrees to indemnify and hold harmless
the Company and each such attorney-in-fact against any losses, claims, damages
or liabilities (or actions in these respects) that arise out of or are
based upon any untrue statements or omission of necessary facts in the
information provided by the undersigned to such attorney-in fact for purposes of
executing, acknowledging, delivering or filing Forms 3, 4 or 5, Form ID or any
other form (including amendments thereto) and agrees to reimburse the Company
and such attorney-in-fact for any legal or other expenses reasonably incurred
in connection with investigating or defending against any such loss, claim,
damage, liability or action.

This Power of Attorney supersedes any power of attorney previously executed by
the undersigned regarding the purposes outlined in the first paragraph hereof
("Prior Powers of Attorney"), and the authority of the attorneys-in-fact named
in any Prior Powers of Attorney is hereby revoked.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier (a) revoked by the undersigned in a signed writing delivered to
the foregoing attorneys-in-fact or (b) superseded by a new power of attorney
regarding the purposes outlined in the first paragraph hereof dated as of a
later date.

	IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this _17_ day of March, 2017.
