I looked up "timed release technology" in the Wikipedia. I'm guessing
from what I read there, and this is only a guess, that the timed release
technology is in the pellets, not in the capsule. However it looks like
it's possible that it could be in the capsule.
I then decided to look at the drug label, so I went to
http://dailymed.nlm.nih.gov
and entered "effexor" in the search box.
The labels mentioned "extended release" but I didn't see anything at all
about how the timing was done. I was surprised however to find that the
drug is sold as an anti-depressant. Searching for "hot flushes" (or
flashes), the main thing I found was that the drug can be prescribed for
panic attacks, and that one of the side effects of panic attacks can be
chills or hot flushes. Hot flushes were also observed at a very
slightly increased rate (3% of effexor patients vs. 2% of placebo patients.)
I wonder if this is being prescribed for you "off label".
So I then searched Google for (effexor "androgen deprivation therapy").
I came up with this interesting web page:
http://www.prostate-cancer.org/pcricms/node/197
There I found this:
"6. The antidepressant venlafaxine (Effexor-XR®) at a dose of 12.5 to
37.5 mg can be very effective at reducing hot flushes.13 If men also
have symptoms of depression while on a TIP, venlafaxine should be
considered as the first choice of medication for severe hot flushes."
According to that, your 37.5 mg dose is the maximum that should be
prescribed and your 75 mg dose was double the maximum. Note the "6" at
the beginning of the paragraph. This was only one of seven different
prevention and treatment strategies mentioned for hot flushes.
I suggest calling the doctor and asking for a 12 mg dose.
