Blood thinners
Postby triangle » Sat Mar 03, 2012 2:03 pm
The vascular surgeon has put me on blood thinners for two months - 75mg of clopidogrel (seriously, who comes up with these ridiculous names??). Since then I feel I have lost some of my fitness. I struggle a bit where i had not previously and I am unable, for example, to put out the same power in threshold intervals that I was managing routinely up until the day before the surgery. The difference is not huge but enough that i feel I have lost some top end power and stamina. This is contrary to my secret hope that I was only one stent away from turning pro Anyway, anyone know if perhaps the blood thinners are giving me some grief or am i just making excuses? I only have just under six weeks of them left so it's not that big a deal but i am curious ...

LOL! Good to know that I don't need help to be crap. Thank yousogood wrote:You are making excuses. Placebo effect as far as clopidogrel is concerned. Clopidogrel is an anti-platelet agent, similar to aspirin.

Aha! I take mine first thing in the morning. That must be it .. taking them at wrong time .. experience drop in sustainable power whilst on bicycle. No doubt a common and well documented problem I feel better now.foo on patrol wrote:For what it is worth.......

Go to the web site and have a look at the general programe for Thursday. It had something to do with diet and eating different types of food!

A friend fractured his pelvis in a crash (wet manhole cover) not long ago - he was put on thinners for several months and forbidden to ride while he was taking them.

The surgeon told me to wait 48 to 72 hours and then get back on the bike. He just warned me not to cut myself shavingRonK wrote:So, your doctor has no objection to your cycling while using blood thinners?

I had daily blood tests for about 10 days so they could get the dosage just right and apart from just being extra careful not to bumble into things like lawn movers and whipper snippers I didn't have any trouble. Razor cuts and other little dings did take longer to stop bleeding but the doc dismissed any reports of bleeding to death after falling off the bike as being 'rubbish'.
Hope it all works out well for you.

There are "blood thinners" and "blood thinners", and different levels of "thinning". In general, a fall or fracture whilst on blood thinner will make the bruise/blood clot worse, but it's not a specific contraindication for exercises. So adjust one's risk level accordingly. Along this scale, one will need to take more care whilst on warfarin as it's only used in situations where "serious thinning" is needed. Pelvic fracture is also a special condition and there's good justification for a major risk reduction.RonK wrote:So, your doctor has no objection to your cycling while using blood thinners?

i was on clexane for a couple of weeks after a clot and i wasn't permitted to do anything strenuous for a short while - i believe this had more to do with not provoking the clot into dislodging and allowing it to be gradually reabsorbed into the blood stream.

Yup - none of that advice was based on science...jules21 wrote:i thought the risk of riding while taking blood thinners was of more severe haemmoraging in a crash?

Five common "blood thinners" are used.
Heparin (Clexane\Fragmin...) is given by injection and lasts about 12hrs. It's the primary treatment of clotting (DVTs) or preventing them (around the time of surgery).
Aspirin which has no significant effect on blood loss and a minor but important effect on preventing clots in arteries (heart).
Warfarin which is a tablet which alters blood clotting by starving your body of a vitamin necessary to make clotting factors.
Pradaxa is a new tablet which has a similar effect to warfarin but is easier to monitor and at this stage, considered as safe as warfarin.
Clopidogrel is a tablet that paralyses platelet initiated clotting. It's used for preventing stents in arteriers (carotids, heart, kidneys) blocking.
Of these, low-dose Clexane will not increase bleeding, but a standard dose will increase bleeding, usually not dangerously. If the dose is a "therapeutic" one or incorrect it can be life-threatening.
Taking warfarin and exercising is mostly studied in older patients and is considered safe. Safe for the demographic is probably pulling a shopping trolley, not MTBing.
Pradaxa - probably too early to tell.
Clopidogrel - about half the people taking it will have marked increase in bleeding time (time to clot). Otherwise there is no change in clotting.
And there endeth the lesson....
So it's mostly safe.

That's a reasonable understanding of the risks involved. With it comes with increased risk and severity of bruising and haematoma formation when enclosed. Excess bleeding when there's open wound.jules21 wrote:i thought the risk of riding while taking blood thinners was of more severe haemmoraging in a crash?
