Essential Thrombocythemia: Looking for information and support

On June 6 my platelets were at 721, and when I started the hydroxyurea on June 20 they had climbed to 891. (I thought that was quite a jump in 2 weeks time) So I am anxious to hear what they are now after a week on the medication. I had my blood test yesterday, and haven't heard from anyone....I'm assuming that to mean that no change in my dosage is warranted, but I may call tomorrow to find out for sure.

I have been living with ET - CALR for a year. HU and daily Aspirin. 500 for 5 days 1000 for two days. Dr. wants me below 300 for platelet count. I started at over 800. I finally got below 300 a year later. Only side effects of HU I’ve experienced is sensitivity to the Sun. 70 sunscreen seems to do the trick and hanging out in the shade. I’m 67 and active. I’m concerned about my immune system being compromised especially with Covid becoming endemic. Still wear a mask and avoid indoor gatherings. I feel isolated at times due to this.

Sounds like your doctors are doing all the right things. At the beginning I also had frequent blood tests to see if HU was doing the job. I also take a baby aspirin. Finally after many ups and downs, I'm on 1,000mg HU and baby aspirin. First year was toughest, my gut didn't like HU, but now it got use to it. My platelets are in normal range and holding.

Similar situation—the drug warnings are enough to scare anyone! I rescheduled a meeting w/Doctor (not LP) who took one hour to explain my diagnosis and prognosis. this really helped me to better understand the Rx options. He did cut the dose in half (LP prescribed 500mg Hydroxyurea daily) so I take 500mg every other day for one month then test to see if it is sufficient for a reduction. I too do not like meds, but better than stroke or heart attack! 😳 BUT, if I die tomorrow I’ve had a great life. I am now focused on my bucket list and trying to keep a sense of humor about it all! 😊 🙏🏼 Best, Jan

I am 71 yo female, reasonably active, recently diagnosed with Jak2, with platelets rising to 750 over 3years. Prescribed 81mg aspirin every day and 500mg Hydroxyurea every other day for a month then test. Goal is slow to 500 range to minimize side affects. I was pretty shocked to read of side effects. Dr explained Rx has to share all side effects—even for high dosages; hopefully I will not experience any side effects at such low dosage. I live Hawai’i so hard to avoid the sun —esp when I worship the sun! Hope this helps. With Aloha, Jan

Hello @kapow and @winmil99. Welcome to Mayo Connect! I thought I’d include both of you in this reply since each of you just recently joined the forum with a new diagnosis of Essential Thrombocythemia.

ET can develop slowly and often people don’t require any medication or treatment initially. However, having too many platelets can cause strokes and other serious issues. So your hematologist will help you decided the best plan of treatment to avoid health risks.
Often the first line of treatment can be a simple daily aspirin to keep the blood thinner. But for some people the risk can be greater and aspirin alone won’t be enough to keep the platelets from sticking together and forming clots.

If the proliferation of cells becomes too high, that’s when medications such as Hydroxurea or other treatments come into play by helping the body to produce fewer cells to keep the balance in check.

The internet is full of rabbit holes that can lead us to anxiety producing sites! Most of it won’t even relate to you so it’s best to steer clear. But, since knowledge is power, I’m posting a few credible informative sites for you to read about your newly diagnosed blood condition.

We have several members who also share this blood condition where the body makes too many platelets. So you’ve come to the right place to meet up with members @eileen11108, @getti @kto1452 @mortysdad @nohrt4me @dwlowrance @paulhayne and many others.

The 3 of us are very close to the same age. I recently turned 69 and just celebrated my 4th ReBirthday from a bone marrow transplant. I had AML, a very aggressive from of leukemia. To that point I only had Vitamin D in my medicine cabinet and loathed taking any medications! I lived a very ‘clean and healthy’ life but still got a blood cancer. So I can understand any reluctance to take meds. But sometimes they are necessary to restore our health and to keep us active. We start from a new benchmark and go forward. ☺️

@winmil99, your platelet level is 543 and your Hematologist would like you to take HU, @kapow, what was your level when you started the Hydroxurea?

I am about to turn 70..active healthy woman . Vegetarian x 50 years. Run, kayak, and practice yoga x 50 yr. Routine blood work reveals plt trending up x 2 yr now..430- 602 now at 543..I was referred to hematologist who told me my diagnosis is prob ET. ..blood smear reveals JAC2 pos. But BCR/ABLI MRNA neg.. will ge getting bone marrow test soon…My Dr wants me on asa daily and now wants me on Hydroxyurea …I do not want to take that drug..It just bothers me to take a chemo…are my plts high enough to be warranting that drug?Is it the JAC2 pos diagnosis that needs the drug? Just starting to read about it. ..any info is helpful. Thanks , cathy

Hi everyone. I am a 68 year old woman, physically active with controlled asthma. I just recently had a small stroke caused by a blood clot in my carotid artery. I have had surgery to remove the clot, and have been able to return to my life with no lingering after effects from the stroke. (My whole right side had gone numb, and I was unable to walk, but it all has returned to normal) But as a result of this they finally looked more closely at my bloodwork, and discovered that my platelets have been elevated for the past 4 or 5 years. A genetic test was done on my blood and I was told I have Essential Thrombocythemia. But they took a bone marrow biopsy and aspiration the day that I was told. Those results are not back yet. I am asking for help in knowing what questions to ask of my Haematoligist. (She has started me on 500 mg of Hydroxyurea which I have been taking for a week with no siginficant side effects and I am having blood tested weekly right now.)

Bueno saber! Tomo aspirineta también.

Hola, soy CALR también, tomo hidroxiurea desde hace 9 años. Actualmente tengo 40 años.
Tomo 1 gr 6 veces x semana y 1,5 gr el día restante. Además una aspirineta diaria.
Sin efectos secundarios x ahora, salvo el cansancio.
