LETROZOLE SIDE EFFECTS; PLEASE HELP

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Tinkabell

 

You have specified a rather unusual regimen for taking Letrozole. Do you mind my asking, is this an approach advised by your Oncologist or BCN, or is it something you have arrived at yourself?

 

It is very important to take medications in the manner we are advised, or they might not be effective at all. Different drugs will have different doses to allow for differences in their chemical nature. Some medications need more packing in the tablet than others, so will be administered at what appears to be a higher dose. It doesn't mean that a drug given at a higher dose is going to be more powerful or have worse side effects than one at a lower dose. You might find it helpful to ask your pharmacist about this - I'm sure they can put your mind at rest. 

 

The half-life of a drug is the time required for the concentration or amount of drug in the body to be reduced by one half. It doesn't mean there is enough in your system to skip doses, in fact it is very unwise to do this unless advised by the doctor supervising you. (Forgive me if you are acting on your Onc's advice.) For some drugs to be effective, it is important to maintain a particular level in your system.

 

You do need professional, expert advice on this. Your problems with Anastrozole could relate, at least in part, to the effects of oestrogen depletion and not purely to the drug itself. Perhaps a specialised pharmacist could help you with this.

 

All the best

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Hello everyone,

I am starting on letrozole this week after stopping anastrozole  (Arimidex) after six months because of evil side effects.  I am going to take it every other day for two weeks, then I will take it two days then miss a day for two weeks and so on.  

I did   this with anastrozole but I could not  manage 1mg a day of it.  All the side effects kicked in big time after two months of slight s/e's. Really awful time.  

 

Letrozole has a "half-life" of two days, meaning I can safely miss a dose because there is enough in my system from the day before.  According to the little booklet the breast nurse gave me, letrozole can diminish or even shrink existing tumours.  

 

I am worried about the dose being 2.5 mg whereas anastrozole was only 1 mg.  Can anyone help me on this please?   Is it a more powerful drug which can turn out to be worse than the anastrozole (anasty tablet).

Hello Pippi

Going back to your first question, I agree with Loolarch and Sandra49.  Most people are drawn to a web-site like this once things have started to go wrong, so the comments are bound to be more negative.  You are unusual in thinking ahead and looking for the pros and cons.

I took Letrozole for about two and half years before I realised I was in trouble.  During that time, I was regularly asked how I was getting on with Letrozole and I thought I was OK.  It is difficult to tell the side effects of the drug from the effects of the menopause.  I was 69 when I started on Letrozole, so way past the menopause.  I only gradually realised that I was getting more cramps in different places and feeling in more of a fog than before. Was this menopause? was this ageing? 

Two things made me question the drug. I developed glaucoma and was worried there could be a connection with the Letrozole. The cancer specialist went through the assessment tool with me. The connection with eye problems is possibly not really there.  Also, it seems the preventative effect of Letrozole is highest in the early years and decreases as time goes on. 

The other factor which un-nerved me was that I began to lose weight without really trying.  You might have thought I would welcome this, but after a few weeks and a few kilos, I got scared. I have put back some weight now I have stopped the Letrozole.  I think I have lost muscle mass, but sadly not the fat.  I continue to take the alendronic acid and combined vitamin D/calcium to prevent against incipient osteoporosis. I still get annual mammograms.

This forum has been very useful.  It has put my feelings about the side effects into perspective. It is all very individual.  However, the drug is a very powerful one, and I would have benefitted from more explanation on how to cope with its effects from the beginning. I signed consent forms for surgery and radiotherapy, but nothing similar for the drug regime.

Pippi - I wish you the best in your treatment. It is good to hear what others have to say, but ultimately the decisions have to be your own.  Good luck.

Hi pippi1969
No I take VitD & Calcium to counter the effects of Letrozole. So for bone strength etc. Feeling fine on Letrozole though, just took time to decide which time of the day was best to take the different tablets.
Take care xx

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Did you mean you take VitD and Calcium to prevent nausea from the Letrozole??

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Hi, I've been taking Leyrozole for over 6 weeks and am fine. I take it just before I go to bed. Still wake up with hot flushes a couple of times but no other side effects so far. I also take VitD after breakfast and Calcium after evening meal, as they can make you feel nauseous. Good luck xx

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Hi pippi
It seems to be best taken in the evening, with food, which prevents the nausea.

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Thanks

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Hi Loolarch yes never thought that. The people who do alright won't post on here as they feel ok and it is usually when people have problems that they post here for support.
Will start mine tomorrow 😊

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Hi Pippi, it is all individual i think. I have never had nausea with letrozole. I take it every evening with my tea. The bone pain is my weakness i think as i had it through chemo too. I dont have hot flushes either. Dint be put off just give it a good go xc

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Hi Pippi

 

I've been on Letrozole for three months now (two different brands so far, and no difference between them) and side effects have been very little problem. I do get hot flushes but no worse than I experienced during menopause. I think Its likely that people who are having little or no problem are probably not even looking at this forum, let alone posting, so you might get a biased view of the likelihood of problems. 

 

Good luck xx

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Side effects have got a bit better on letrozole.  I also think the impact is very dependent on how far into the menopause that you are.  I think I also suffered horrible symptoms at the beginning because before being diagnosed with breast cancer i had been on HRT for two years.  So the combination of losing HRT and a drug that takes away oestogen was pretty grim.  I did also get bladder infections at the beginning.  Symptoms have got better over time although there is an ongoing impact on my bones and I am do get more sweaty and tired (though tiredness could also be down to the surgery).  As I have mentioned in an earlier post I do not think I will be on Letrozole for 5 years but might be on the drug for 2 years (which I understand is the most productive time).  So you may be lucky and you may not get many symptoms or they may be controllable.  Whether you stay on the drug is a different matter - and that I am sure will depend on your risk factors and the impact of the side effects.

 

All the best.

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Hi I have been prescribed Letrozole today but not started them yet. But reading on here it sounds like this drug is going to give me a or of pain, fatigue and possibly nausea. For me the nausea would be the worse. Is there anybody o here that actually can say that they are managing ok with the side effects or the side effects got a lot better after some time? Bit worried now really...

Re: LETROZOLE SIDE EFFECTS; PLEASE HELP

Ive only been on letrozole for 3 weeks but I'm already taking carbimazole for overactive thyroid. This has the same side effects so now I'm getting double se. I'm hoping it will settle down like the carb did (been on these 10months)

I try to go for a short walk each day and drink plenty of water. I'm also using muscle rub on knees, calfs and ankles and toes this helps. I take 2 naproxen before bed too, it's manageable but when I get new prescription from docs I'm asking for Accord brand as the hospital have me Crescent.

I've already asked the pharmacy if they can supply it and theve made a note on my record.

I'm almost 61 and thought I'd got past all the hot flushes etc but theve kicked in again. Got a mini fan to use again. Also if my joints get cold that makes them worse or if I'm not very active. I sit and craft a lot but the walks help .

Just hoping things settle down eventually. Going for my planning session on the 2nd Oct for radiotherapy. All done for xmas and feeling better,
Fingers crossed.
