Vivelle vs. Estrace [posted 8/10/98]
Question: I use Vivelle .75 and natural progesterone cream (10% compounded). The
Vivelle and all the other estradiol patches cause what looks like
chemical burns on my skin with severe itching. Also, after complete hyst
this summer it looks as though I need something stronger. If I switch
to estrace (since it is estradiol) will I be nauseous from it? I once was
given a 2 mg prescription in perimenopause and got a severe migraine and nausea. Now I
realize this was an overdose. Also, I have been advised that .5 mg estrace
can be used sublingually, not swallowed to spare the liver. What are your
opinions? However, should I be on another form of estrogen entirely since I
now have no ovaries?
Answer: In general, I am a strong advocate of estrogen replacement for women unless there is a strong history of cancer of the breast. The dermal estrogens probably have less liver toxicity. I would favor them – especially if you have had migraines with estrogen since the serum levels are touted as lower. There is a new drug coming out that is a “designer” estrogen. Expensive, but without the risk of breast cancer. What the effect will be on migraines and liver toxicity remains to be seen.
Switching from Premarin to Estrace [posted 7/23/98]
Question: I’m a very sensitive (physically) person and it took me one year to get
settled into premarin and now my husband’s insurance company switched
switched me to estrace. Will I have to endure another year of
adjusting, with upset stomach and bowels?
Answer: Well, hard to know. I have patients who clearly need one brand and many who don’t seem to vary much with different brands or delivery systems. Can’t tell you off hand why, but you’ll need to see for yourself.
Estrace – Adverse Reactions to [posted 7/17/98]
Question: I was prescribed Estrace and I got very sick,
felt like I was going to pass out and had trouble breathing. After
further blood test, at my insistence,
they came back normal. Since I was taking the estrace for about 1 week, I have
this crushing feeling on the left side of my chest. Could taking this drug when I did not need to cause any damage? Other medications
that I take are Wellbutrin, xanax, and moduretic(for fluid retention).
Answer: Certainly would be uncommon/rare/unusual for estrace. The only way to tell is by stopping the
drug. If the problem abates, restart the drug and see if it returns. If so discontinue the drug.
Estrace
Question: I have been taking 1 mg of Estrace for the past 3 months. Recently, I have noticed substantial hair loss. Is this a side effect of this drug?
Answer: Estrace(estradiol) is basically an estrogen replacement drug. All estrogens are metabolized
through fat and other glandular tissue into testosterone. The testosterone is the hormone
responsible for hair loss. However, without the estrace base, the levels will be low. Many
women have hair loss in a “male pattern”. This represents the loss of hair present on the genes
they inherited from their parents. Their male children will usually present with earlier hair
loss than average. Rogaine is usually very helpful in these women although it is expensive and
necessary on a lifetime basis. However, your hair loss will continue as long as you are on
the estrace.
