Mucinex partnered with TikTok for a Halloween-themed marketing campaign urging customers to share their costumes on the platform.

The collaboration consisted of Mucinex urging TikTok users to share their before-and-after looks as they dressed up in their Halloween costume. The "Too Sick to be Sick" campaign had TikTok users post videos showing the difference between their "Too Sick" look with a cold and their "So Sick" Halloween look. 

The partnership also included Mucinex utilizing several TikTok influencers to suggest potential styles for their fans, all using the hashtag #toosicktobesick.
