Azo yeast pills!

Cassidy
Hi guys! Ok so I've been dealing with a recurring yeast infection for a few months. I've gone to 3 different doctors and what they gave me for it never fully cleared it up!
My grandma gave me a pack of Azo yeast plus pills she kept for situations like this. And they WORKED, AMAZINGLY.
I could believe how fast it cleared up.
But after a month of relief it came back and this time the pills didn't work because they changed the formula!!
I've been trying to find a "dupe" for the old formula but haven't had any luck.
Do you guys have any remedies, homeopathic or OTC medicines that worked for you??
I'd love anyone's help!
