I am a new user of estrogen patches - I started a once-weekly patch three weeks ago.
I have a theory about these patches from a pharmacologic standpoint.
I don't think these patches (at least the once-weekly ones) do what they say with regards to maintaining a steady dosage. Like - at all. I know that in any medication regimen, it's going to be difficult to establish a truly levelized therapy - but I do think that these estrogen patches may be fudging some of the number more than other types of transdermal medications.
For the first ~24hrs after I apply a new patch, I have a varying number of symptoms, but I am noticing a pattern after my third patch. I apply my new patches on a Friday evening, and I spend the entirety of Friday night and Saturday with VERY sore, stiff legs. I hobble around the house like an old lady. I also notice throughout the course of Saturday and Sunday, my vaginal dryness/VA and mood also show very marked improvement. On Friday nights after applying the new patch, I actually almost feel a bit high.
I acknowledge that HRT seems to be complicated by the fact that the placebo-effect is quite high with it as well, but I am definitely NOT imagining the sore leg thing.
I have also noticed that - throughout the week - it's almost like my body will "hit" a new reservoir of estrogen in the patch and I start feeling pretty good again.
It's really weird but......personally, I don't see how these patches can maintain a steady dosage. Especially the older generic types that don't have the funding behind them of the big drug companies to innovate new delivery systems.
Thoughts?
