Anyone else find the side effects of Hydrea 500MG frightening?

Posted by eddb @eddb, Oct 1, 2023

I was diagnosed with having a blood cancer that looks and acts a lot like Polycythemia Vera (PV) about 6 years ago. I’ve been rolling along ok with (mostly monthly) phlebotomies, until a year or so ago. At that point my white blood cells and (most importantly) my platelet levels started to increase. The doc did a 2nd bone marrow extraction but I STILL tested negative for PV. After a CT scan and other tests were done to rule out any possible hidden bodily infections, my doc prescribed Hydrea 500 MG. I filled the script about a week and a half ago…and it is still sitting in a bag on my counter, unopened. I got seriously freaked out when I researched the drug and found all those nasty side effects associated with the drug.

Now, I’m sitting here knowing that my platelet count as of 3 days ago was 987 (over twice the normal level limit) and that I could throw a blood clot at anytime. I was holding off taking the drug, to get an appointment with a hematologist/oncologist for a 2nd opinion, but that appointment isn’t for another 10 days - I’m a nervous wreck! I do not want to take the chance with hydrea but I don’t want to clot. I don’t even have a real diagnosis other than suspicion of bone marrow cancer or the beginning stages of it….

I’d be curious to hear about what others have experienced while on this drug. Much appreciated!

@jbcl thanks for your compassionate reply. May I ask what your platelet count was when you started on the 500mg of Hydroxyurea ? Has your dose been lowered now that your platelet count is back in the normal range?

My dose has not been lowered...possibly because I am 72, my doctor feels I am at greater risk.
My highest platelet numbers were 536, now they are around 230.
I know some people take the 500 mg 3 times a week, but I take it every day. I am blessed because I have had no negative side effects and many people can tolerate it well. Apparently children with sickle cell anemia take it without any issues .
Again...if I may suggest, pray about it, and do what you and your doctor feel is best.

I know this diagnosis can be surprising and very scary. I was diagnosed at age 71 with no symptoms except a climbing platelet count.
After consulting with a hematologist/oncologist, and hearing the possibility of blood clots and stroke, he diagnosed daily baby aspirin and 500 mg hydroxyurea. I continue to feel no symptoms, but after 6 months, my platelet count has dropped into the normal range.
Do research, and read the comments on this website, which are very helpful and comforting.
Only you can decide what is right for you. May God guide you in your decision.

Hello, I just joined the Support Group today. I was diagnosed with ET yesterday. I tested positive for the JAK 2 gene. My platelets counts are in the upper 500s. I am 61, but am otherwise healthy with no risk factors. Do you think I need to go on Hydroxyurea or can I try a more natural treatment?

@nohrt4me my daughter is a nurse who doesn’t want me to jump into anything with so many possible side effects, without looking at different options. Are platelet counts in the upper 500s super dangerous? What were your counts when you started treatment? What have been your side effects over the years? Thanks for responding to me!

nohrt4me makes a great point.

Ask your daughter how many patients she knows with ET.

Then ask your oncologist the same question.

Please remember, you're among friends here.

You must find your own way forward, but you are not alone.

@cetzler I have had no side effects except constipation and very mild hair thinning. The hair thinning reversed after a few years. This is not "I have bald spots!" thinning in my case. I was having severe fatigue before starting HU. I felt better after I started it.

Other people have nausea, insomnia, or diarrhea. My doc prescribed Compazine (anti nausea) for me with HU, but I never needed it.

Starting HU as soon as it is warranted and at lowest possible dose, increasing only to whatever keeps you in stable is what most docs do, and this gives patients time to acclimate. If you wait to start HU and let platelets run high, a doc may start you on a higher HU dose, which you may not tolerate well.

Any platelets over 450 can be "dangerous" depending on mutation type, age, and clot history. Yr doc should be able to give you Vegas odds on developing a clot if you don't take HU vs if you do. There is statistical research that shows people on HU have fewer clots and live a normal lifespan.

My dad also had ET. No one knew it until he had a leg clot. He had to go on coumadin, which threw him in the hospital a couple times for internal bleeding.

I get why your daughter is nervous about HU. It has a scary "black box" warning. The big question is whether YOU feel nervous about it and whether you think your daughter has more experience and knowledge than the doc who wants to prescribe it.

There are alternatives to HU--anagrelide and Besremi. Besremi is usually rejected by insurance for ET patients because it is super expensive. But if you are rich or have great insurance, you could ask yr doc about that.

Fwiw, I have family that gave me a hard time about my treatment. But it's not their body, and I am glad I chose the options I did.

@cetzler Welcome to the club no one wants to be in!

What "natural treatment"? I've had ET x 18 years, and there isn't a supplement or diet that addresses out-of-control platelets caused by a genetic mutation, though I've seen claims for everything from CBD oil to cinnamon to personalized IV infusions.

Some people right after diagnosis do feel they need to at least try an alternative treatment before they agree to HU. If that's what you decide to do, it's a good idea to let yr doctor know that's your plan so that you can be monitored appropriately.

Your oncologist will assess your need for hydroxyurea based on age, mutation type, and clot history. Docs may also look at your family history for types of strokes, heart attacks, and clots.

Doc will prob also recommend a daily baby aspirin, which reduces clot risk.

You *can* benefit by a heart healthy diet and appropriate exercise that will reduce over all stroke risks. Get a handle on weight, hypertension, and cholesterol if you need to.

Hello cetzler. An ET diagnosis is shocking. Who even knew you could have too many platelets? You must have a million questions.

I'm so glad you've found this forum. You can learn so much here. Best of all, you'll meet people who have lived strong with ET for decades!

But to make a treatment decision, you must rely on your oncologist. Ideally, she or he specializes in MPNs. If not, you may wish to seek a second opinion. ET is so weird that many doctors don't understand it at all.

With ET, a genetic mutation disrupts blood cell production. No food or supplement can undo that mutation.

Expect to be confused as you learn more. But you will find a way forward!!

two month ago started on 500mg 3 days a week, the first dose i have vascular effects, and nearly went out of the floor, called dr office seemed to dismiss, and said continue with it.... than they raised me to 1 per day more problems, and my platelets of 1 million went up not down, so they upped again 2 more pills total of 4500mg per week.. Now i'm high risk, as i have multi other medical issues that were under control that hydrox . I have a tummy wrap for a hernia repair, i can't throw up, so i get all this foam and dull pain in the wrap area.. i had grout symptoms so bad i couldn't walk for a week again my complaints went unheard,, I am getting a second opinion on Tue from Fred Hutch in Seattle, as the Big Private Cancer clinic in puyallup, has failed me, they don't follow threw, i haven't had a blood test since they upped my meds, have had to call EMT's twice due to foaming and dull pain in chest, as you are at high risk for heart attack and its hard to tell the differance when it stops you in your tracks and doesn't ease up, goes up your neck to ears the dull pain.. i'm almost to the point of just using my am and pm asprin and putting this in Gods hands, as to me the quality is better than sitting inside. But i don't want to have a stroke and be a burden to my family, as i only have a couple of sisters.. So we need more research and better meds for this disease.. it been a low priority not many new break throughs in 30 years, there are a few trials going on.. but i can't do them...

@ladyplumber7 Hello. Sorry you’re feeling so miserable and concerned. I have taken 1000mg of HU daily for over 5 years. There are side effects, mostly fatigue, that I attribute mostly to the HU but, at almost 79, some of those side effects I know are just from getting old.
There day I had the bloodwork done that let to PV diagnosis, I had some terrible pain in my knee and that was gout that was also found that same day.
I take allopurinol for the gout and, for the most part, have had very little to complain about.
I agree that you need a really good GP who can tie all your health issues together and help you decide the best meds and course of action for you.
I work on the theory that “God helps those that help themselves” so don’t give up. You just need to find a provider that listens to you, treats the whole person and makes up a program that actually helps.
Also, I know that diet and exercise can be critical to your overall wellbeing when you’re on HU.
Please, if you can, let us know how it goes with that second opinion,
