do not use mirvaso

PLEASE DO NOT USE THIS CREAM. I had some redness on one side of my face, so my dermatologist prescribed Mirvaso, not mentioning the possible side effects. I applied a small amount on my entire face and the redness was completely gone in 30 minutes, I was so happy to see that this is working for me, 3 hours later, my face was burning and looked completely red, way worse than it was originally. I did my research on Mirvaso and was shocked by all the negative reviews on this product. I only used it once and 2 days later my face is still red and flushing. I hope one time wasn't enough to ruin my face. I don't even understand how Mirvaso is FDA approved when 90% of the reviews are negative.
