Hi. I ve gone through your query and I can understand your anxiety. Most reported causes for vaginal itching & dryness could be yeast infection, low estrogen levels in the vaginal area or Lichen Sclerosis (due to testosterone deficiency). From your history, I understood that you are already on medication for yeast infection. The most common side effect of monistat itself are itching, peeling,dry skin, vaginal burning or irritation after insertion of tablet. So in your case it could be due to monistat or low estrogen levels. I advice you to, stop monistat & use topical estrogen, lubricants & also to maintain personal hygiene. Hope I have answered your query. Let me know if I can assist you further. Take care. Regards, Dr. Yogapriya V, General and family physician.
