Have the Ivermentic lotion from Walgreens. Have questions.

I’ve seen a lot of people using the Walgreens ivermectin for rosacea relief. So I got some. Along with my regular rosacea symptoms right now I’m dealing with a constant burning and itching to my skins, despite all the moisturizers I’ve tried. With the dry burning, it seems little bumps are popping up. I’d like to try the ivermectin but was wondering if it will help or make the itching/burning worse. Any advice is highly appreciated! TIA.
