                           LIMITED POWER OF ATTORNEY
                      FOR SECTION 16 REPORTING OBLIGATIONS

     Know all by these presents, that the undersigned hereby makes, constitutes

        (1)   execute for and on behalf of the undersigned, in the undersigned's
capacity as a director of Trevi Therapeutics, Inc. (the "Company"), Forms 3, 4,
and 5 (including any amendments thereto) in accordance with Section 16(a) of the
Securities Exchange Act of 1934, as amended, and the rules thereunder (the
"Exchange Act");

        (2)   do and perform any and all acts for and on behalf of the
undersigned which may be necessary or desirable to prepare, complete and execute
any such Form 3, 4, or 5, prepare, complete and execute any amendment or
amendments thereto, and timely deliver and file such form with the United States
Securities and Exchange Commission (the "SEC") and any stock exchange or similar
authority, including without limitation the filing of a Form ID, Update

        (3)   seek or obtain, as the undersigned's representative and on the
undersigned's behalf, information regarding transactions in the Company's
securities from any third party, including brokers, employee benefit plan
administrators and trustees, and the undersigned hereby authorizes any such
person to release any such information to such attorney-in-fact and approves and
ratifies any such release of information; 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

     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

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

failure to comply with such requirements, or (iii) any obligation or liability
of the undersigned for profit disgorgement under Section 16(b) of the Exchange
Act.

     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 revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact.

     IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 7th day of May, 2019.
