Severe nausea and headaches.
I absolutely hated this product. My dermatologist prescribed me it for my severe acne, and I wish he didn't! It made me severely nauseous, to the point where I couldn't eat for days. I generally felt ill 24/7 and had severe headaches and dizziness. I could barely function throughout the day and noticed no change in my acne whatsoever. Having to run out of a supermarket and a workplace to vomit isn't fun at all! I wouldn't recommend this product at all! And if you're on it, I hope you have better luck than me!
