Stinging Eyes After Using Rogaine Foam

Dr. Rassman,

I recently started using Rogaine foam. I applied it at around 7pm and went to bed around 1 am. I wanted to be sure i didnt react negatively. I was fine until after i went to bed. Around 6 am i woke up with stinging and tearing up in both my eyes. I had to go to the bathroom and rinse out my eyes for about a minute. They were all red and puffy too. It seems like it might have been an allergic reaction, but is there also the possibility that some of the foam residue got onto my pillow and i rubbed my eyes into it during the night?(Because i applied a lot and all over my head). Also, after washing out my eyes i was fine. Have you heard of this before?

Minoxidil can be irritating and if you did get any into your eyes, what you are reporting is logical. If it should happen, be sure to wash out your eyes, under a shower with the water pouring into your eyes from hitting your forehead.
