Lil Wayne is taking seizure medication following his mid-air medical emergency last month -- when he suffered seizure-like episodes on two back-to-back flights -- so says the rapper.
Weezy was giving an interview with MTV when the room got hot, and he said, "Please let them know that I have an air unit, but because of the sound, they don't want the air on, so it's super hot in here ... I don't want y'all to think I'm on nothing, man. I'm on seizure medicine. That's all."
TMZ broke the story ... Wayne's also been given orders by his doctors to stay off airplanes for the foreseeable future.
