Just wondering how other pharmacists answer these common questions and if you can share yours- just trying to see if I can improve my responses. 1 How to prevent reoccuring yeast infections? Do you ever recommend probiotics? I know it's fungal but have read some articles stating probiotics have potential. 2 Difference between probiotics available? Which one to take? 3 How to help with ringing in the ear? 4 How are Zarbee products for children? 5 How to dispose of old/expired medications? (Have heard of pharmacists recommending to put them in a ziploc bag full of coffee grinds then throw in the trash, but do not understand why this should be recommended) 6 Can coupon (non-manufacturer like goodrx) be used on controls? Thanks for any insight.
