Rosacea and Metronidazole

I was just prescribed Metronidazole cream for my acne rosacea. After paying money for the cream, I read the ingredients list and saw that it has benzyl alcohol in it.

Most every website offering info on Rosacea urges people to stay away from benzyl alcohol because it worsens your condition.

If this is true, and the consensus seems to say that it is, should I not use Metronidazole?
