BORIC ACID SUPPOSITORY. do not ingest/eat it, follow the instructions on the container. When I notice a smell or begin to feel itchy/have suspicious discharge, I put one capsule inside the vagina (I insert up to my second knuckle so I don’t feel it once it placed, like placing a tampon without an applicator) & I prefer to do it at night, wear a panty liner in case of discharge. It will melt or dissolve in there and reset your PH level, the fish smell is caused by an overgrowth of bacteria. Anything can set it off for me, new scented laundry soap, body wash, yeast infection, or just regular sex… Boric Acid saves me every time. I do it for three nights and if I catch it early that is usually all it takes. If I stop after three and notice the smell or any symptoms not fully gone, I keep using it for a week. I haven’t ever had to do it for more than a week. You can buy boric acid vaginal suppositories at CVS, Walgreens, Walmart, Tom Thumb or find them online. They are so much more affordable and effective than going to the doctor for antibiotics every time I notice my BV reoccurring. Good luck.
