The makers of Theraflu -- the medicine, not the track -- don't think Kanye West and DJ Khaled's song is very G.O.O.D. In fact, the company is downright miffed at Yeezy for using their name in the track and as the title of 'Theraflu.'

TMZ reports that the makers of the cold medicine didn't outright say they would sue the 34-year-old rapper, but that they're not happy. "We in no way endorse or approve of the references or use of the image and likeness of Theraflu in this manner," the creators of the cough medicine told the site. "Theraflu is an over-the-counter product used to help relieve cold and flu symptoms that millions of consumers rely on."

On one hand, they've just gotten a bunch of free PR. On the other, we could see how they may not want what's supposed to make people feel better associated with a track dedicated to haters ... especially without clearance.

This isn't the first time this week that Yeezy's upset someone over potential copyright issues. West is currently being sued for $500,000 by Robert “Bobby” Poindexter of R&B group the Persuaders. Poindexter claims that West sampled his track ‘Trying Girls Out’ for his 2006 remix of ‘Girls Girls Girls' without permission.

Sounds like maybe West has been too distracted by a certain lady in his life to pay much mind to his paperwork!
