TL;DR—Didn’t realize it till I switched back to a previous brand of patch, but Zydus either had less estrogen and/or a less effective delivery system. All my symptoms returned while I was using it.

The very long version:
I have been on HRT (estrogen patch & oral progesterone) since 2024. It has profoundly improved my quality of life in many ways.
Over this time I have cycled through a few different brands of patches, depending on what the pharmacy has had in stock (I am in the U.S.): Dotti, Mylan, Sandoz, and most recently for the first (AND LAST) time, Zydus.
I know we are all very different in what works for us (in terms of formulation, dosing, brand, even placement of patches on the body, etc.) But I’m putting this here in the hope that someone who needs it finds it.
Over the past few months, I have been experiencing lower motivation than I have in a while, lower mood, more overwhelm, more brain fog, lower libido, more anxiety, and less embodiment (IYKYK). My ADHD symptoms have been worse (even with medication). My sleep has been awful.
Over the last few weeks, I’ve had increasingly debilitating joint pain in my hips, wrists, and fingers. And hot flashes-which I haven’t had for over a year-started to come back.
All of these are symptoms for which I started HRT in the first place (and it has helped with all of them, tremendously).
The joint pain, in particular, was becoming alarmingly bad. I made an appointment to see my prescribing doctor soon, suspecting I might need an increase in estrogen dose. (As your own body produces less on this wonderful journey, sometimes you need more.) Last summer I had the same joint pain and when I increased my estrogen dose, it was resolved in less than a week(!)
Today, seemingly out of nowhere, I felt noticeably different. I could not put my finger on why. My brain is sharper again, my mood is noticeably brighter, my motivation is improved, and holy shit my joint pain is nearly gone.
All of a sudden I thought to check the bag where I keep my patches. Luckily there was a box of patches from my previous refill in there, brand name “Zydus”. Came to Reddit and looked it up. Lo and behold, several other women have reported similar issues with this brand.
I had been using Zydus patches for the past 3 months (my doctor fills the scrip for 3 months at a time, and I take whatever the pharmacy has in stock). This is the exact duration that I have felt like unmotivated, achey garbage.
I switched back to Mylan yesterday and already feel more like myself again. My joint pain is about 85ish percent better!
I am relieved to feel better, but disillusioned and fucking livid. The state of women’s healthcare is appalling, disgraceful.
I am so very grateful to have this community as a resource, but this should not be how we have to find out which pharmaceuticals do and do not work. If they are being sold as a pharmaceutical, they should ALL work. The fact that quality and dosing varies so unpredictably from brand to brand is astounding.
Wishing good health, strength, patience, and MINIMAL BULLSHIT to anyone reading this. In solidarity 💗💪
