Side effects imatinib

Categories:

Hi all I just got my results on the 15th July for cml and started my 400mg imatinib on the 18th of July the worst side effects are the leg cramps and bone ache like bad growing pains I have been taking magnesium and ibuprofen but no help but just read ibuprofen is bad to take any advice please I have contacted my doctor today and waiting on him getting back to me thanks all I am male and 51 and work in a heavy manual job outside on the railway and hope to get back next week after 4 weeks off work x

Hi sorry to hear you have joined the club none us wanted to be in. We are here however, and we have a condition which unlike 25 years ago, is now very unlikely to be the cause of our death. It is however a serious diagnosis, and you need to give your body and your mind a chance to deal with the impact it has on you.

I was 50 when diagnosed 12 years ago. The bone pain was bad and for me took about 6 weeks for the worst to die down, and 3-4 months to go away completely. Hot bath, hot water bottles etc. helped. The common painkillers are not recommended by the drug companies with imatinib as 1), it can cause stomach issues like ibuprofen does, and 2) is, like paracetomol, metabolised in the liver, and we don't want to over-load that. I have taken both occasionally over the years, and not had any problems, but I try to get by without them.

A few people find the side effects of imatinib so bad they can't deal with them, but most of them do better on some of the other drugs which are available now.

I took 400mg imatinib for 10 years, then reduced to 200mg for a year, and am still producing good test results 8 months after stopping taking the pills. There have been trials which show that people who were in remission (I won't go into the test result details of what that means now - that can wait) and stop the meds following this track have a 70% chance of staying in what is called Treatment Free Remission (TFR). All those who lost remission got it back when they went back on the pills. Current indications are that the best chance of this working is for those who have been in remission for 3+ years, so it won't happen quickly, but when I was diagnosed I was told I'd be on imatinib for life - the science is always moving on. I was asked to do a talk on my experience at the CML Support Group patient day last year - you can see that on this link. As we were very much the same age at diagnosis and on the same medication I hope it might be useful. 

Just a thought on the job front, assuming you are in UK. The old Disability Discrimination Act gave employers a duty to make reasonable adjustment to  working conditions to address any issues caused by a diagnosis of any form of cancer, which you now have. That duty was like many others rolled into the Equality Act 2010. Especially where the bone pain is very likely to be temporary, it is a reasonable question to ask if they can make any adjustments to what you do for the next few weeks.

Most people find it helps them cope with the condition mentally if they understand it well. There's lots of useful information on the "About CML" and "Patient Info" tabs at the top of the page, but feel free to ask questions on here. Between us there is not a lot we haven't experienced or heard about on CML.

All the best

Hi thanks for the reply us men don't like to show weakness but this has knocked me for 6 as I am normally fit and active i am in Scotland and convinced I can go back to work next week but think I am kidding myself and need to sort my head out as well as my body pain it has been too much to take in and only been 2 weeks since getting my marrow results x

Sorry to hear you are having problems with meds!  

I was diagnosed 12 months ago and was also started on Imatinib 400mg.  I was taken off them due to adverse side effects of which bad joint and bone pain was one of them.  I found that taking curcumin and additional vitamin D helped a lot, didn’t cure it but made it more manageable.  I also suffered with chronic fatigue which was causing problems with work ing (heavy manual job) and training. I had to all but give in as it was causing mental difficulties, severe depression and the like.  Be especially careful if you do start to feel down as it can spiral out of control very quickly! 

Hope you get things sorted! 🤞

 

Hi All,

There is substantial evidence that certain NSAIDs such as ibuprofen interact with imatinib to affect the uptake of imatinib and so it and any gels based on it should be avoided when treating musculo -skeletal issues arising from IM treatment.Research at University of Adelaide and in particular a doctoral thesis undertaken by Jueqiong Wang supervised by Professor Timothy Hughes investigated "Contrasting effects of diclofenac and ibuprofen on active imatinib uptake into leukaemic cells".Subsequent and various journal articles have followed and these may be picked up by googling "nsaids and imatinib." Diclofenac came out as an NSAID that did not impact on IM uptake but current medical opinion is that other than occasional use it should be avoided as it can lead to sudden stomach bleeding;I used to take Arthrotec comprising of diclofenac sodium and misoprostal (protects the stomach) but my GP will not prescribe it to me as it appears on a blacklist.I am allowed Naproxen but not for continuous use.One might be given PPIs alongside diclofenac but some of these interact with imatinib.

I trust that this helps

Thanks all for the replies I was in so much pain last night up to 8 am I was up all night as I could not get comfy anywhere and the bone and muscle pain all over was unbearable when my wife got up she gave me a high strength vitamin d tablet
and 200 mg ibuprofen i also had banana on toast i went to bet at 830 am woke up at 1230 and the difference was unbelievable still stiff legs but very bearable my wife had phoned the hospital to say about my severe pain and anything they can recommend to get a phone call a couple hours later to say tell him to stop taking them and to come in next Monday to try another tablet but all the tablets have the same side effects all I wanted to know was if i can take anything to help the pain not to be told we will just try you on something else as I have only been on these since the 18th July

Hi, I think I've replied to your wife on this subject on a different thread. I have sent her the link to the talk on side effects from last year's patient day. In that talk Sebastian Francis says that if you have what they call grade 3 or 4 side effects the specialists will try you on other drugs. They do NOT all have the same side effects; some of them work in different ways, and there are a number of people who have posted on here over the years about side effects on imatinib who have found for example that nilotinib gave them far fewer issues. This link is Prof Steve O'Brien's talk at last year's patient day about the other drugs - so called second and third line treatments. That might be useful.

I know this is horrible for you and your family right now. It does not mean that there is not a treatment which will give you back a very good quality of life; it may just be that it is going to take a little longer for you to find the right treatment for you it than it did for some people.

All the best

Thanks Alastair its hard from being the big strong man of the house with a heavy manual job on the railway to being a broken man in so much pain since being on the tablets but hopefully they can sort me out thanks again and I watched your talk with the link its good to hear other people's stories x

I'm in Scotland too, I was diagnosed in 2003 and was put on imatinib and went through the same side effects and others, I remember walking and finding it hard, but it did clear eventually, so stick with it.

I was advised to avoid ibuprofen and asprin  by my consultant and paracetamol was ok.

You can get other painkillers on prescription that are alternatives to ibuprofen on prescription, ask your consultant or GP.

I took 2 weeks off work, but with hindsight, I  should have taken longer, but wanted to get back to normality.

What I found helped most was to remain optimistic and not let things get me down and discuss how I'm feeling with my family and friends

Are you able to do a phased return to work and build up days until full time again?

That might help you adjust, good luck.

Cheers Kenny my specialist nurse got in touch today I have been taking ibuprofen and magnesium tablets but she has told me to just take paracetamol or cocodomol but I have an appointment this Monday so I will ask more questions then and hopefully these side effects subside and I can get a wee bit normality back
