I claim, the ornamental design for a medication reminder label, as shown and described.
FIG. 1 is a front perspective view of the medication reminder label;
FIG. 2, shows a bottom plan view thereof;
FIG. 3, shows a front elevation view thereof;
FIG. 4, shows a right side elevation view thereof; and,
FIG. 5, shows a left side elevation view thereof.
The medication reminder label in FIGS. 1-4 is shown with a symbolic break in its length. The appearance of any portion of the article between the break lines forms no part of the claimed design.
