BTD Forums  /  Supp Right For Your Type  /  Quercetin and prescribed medication question
Posted by: eva b., Friday, May 29, 2009, 7:45am
Dr D suggested, on another thread, that Quercetin supplementation might be helpful with some of the hypersensitivity/allergy symptoms  I have been experiencing - particularly with my eyes since getting shingles.

I've done some research on the subject, and read that quercetin interacts with a number of prescription drugs, and that I should check with my primary care doc before taking it.  

I am seeing him today, and will ask, but suspect that he is not going to be very well informed on the subject so wonder what thoughts some of the more knowledgeable members of the forum might have.

I am currently taking diazepam and a codeine/paracetamol combination tablet, all prescribed by GP, (gradually reducing doseage) in connection with the shingles pain, as well as diclofenac (an NSAID).

I wonder, is it safe for me to take the quercetin, or would it adversely interact with my current medication?

I recently had a whole bank of blood tests with a rheumatologist, and wonder if perhaps I should wait to ask him for advice?

any input welcome!

if I remember well, it doesn't interact with prescribed meds; but I'd be careful with diclophenac and paracetamol as being an O !!! (pray)
diazepam.... take care in not getting dependent from such a product... :-/
would merely go for aminoacids here, if possible....(smile)

why are diclofenac and paracetamol a problem for type O???
I've seen no references to this anywhere...

I am currently reducing my intake of codeine as my eye doc thinks it may be contributing to the dryness - if I can't take the other 2, what pain relief options are left to me?

I'm starting to feel really worried now ??)

As long as you are weaning off do not worry, sometimes we need these things. Shingles is terribly painful.
I would certainly not be afraid to take quercetin in a low dose to start.


Drug and Food Interactions:
Do not take Quercetin without talking to your doctor first if you are taking:


Cyclosporine (Neoral(R), Sandimmune(R), Sandimmune IV(R), Sangcya(R))
Digoxin (Lanoxin(R))
Certain medicines used to treat infection (ciprofloxacin (Cipro(R)), gatafloxacin (Tequin(R)), levofloxacin (Levaquin(R)), norfloxacin (Noroxin(R)), ofloxacin (Floxin(R)), sparfloxacin (Zagam(R)), trovafloxacin (Trovan(R)))

we were taught that both might create bleedings especialle in O's... :-/
a product made out of ..ou how is that spelled in english...mothersworth or similiar in german Mutterkorn might be ok against pains; dito orthomolecular amounts of calcium, phenylalanine,
B-complex,Vit.C,E,Selen,Mg,l'arginin,tryptophane, for example.

It depends for what kind of pain it is about....sometimes enzyme may be also fine,dito some other antioxidants...also alpha-lipoic acid is a fine thing.

You mustn't feel worried, it may cause...m a y.... it mustn't as usual;
but we, the health practioners just do prefer to work with natural stuffs, instead of chemical bombs with side effects. 8)

thanks, Andrea, what would you call a low dose?

Why not start with once a day. Why not have a look at the health protocols here on the website and see what fits you?

Why did you got the shingles in the first place? Some underlying condition? :-/ Licorice gel? to kill the source?

Someone will know more then me. :)

thanks, Tomatilla, I seem to do OK with NSAIDs (specially since the BTD sorted out my digestive problems 6 years ago! :)) and am careful to always take with food.

As far as other herbs and enzymes are concerned, I have to be very careful because I know from a benzo forum I belong to that they have been known to cause people problems when they are withdrawing from benzodiazepines.... :(

At the moment, I find myself in a real chemical quandary, all of it caused by wrongly diagnosed and wrongly treated eye shingles in the first place... >:(

SOmetimes I would like to strangle the doctors (and there were many of them) who contributed to my current state of health...or rather absence of it.

Anyway, I am remaining ultra-compliant with the BTD now, and hoping this will help the overall situation.

Have you looked at the Genotype diet? or the protocols ;)

I have, and I'm pretty sure I am a Hunter.  However, on an earlier thread where I was wondering which diet should I follow, Dr D said follow the BTD O secretor...

I note there are lots of similarities (I have the book) in allowed foods, but with more avoids on the hunter diet.  

Why do you ask?  do you think it's something I should try?

I would work on the protocols first they are limited to a few weeks.

I just wanted to make sure you were on the right diet. Looks like you are, :).

Dr D
cAMP is depressed in low immune function states.
For example, Herpes Zoster (shingles) is often helped with
injections of adenosine monophosphate, vitamin C and the herb Coleus
forskolin, all of which raise cAMP.

sorry if I'm being thick...but I'm not sure what you mean by "protocols"?
does this refer to the genotype or BTD?

I've been on the BTD for several years (with recent lazy lapses in the last few months, now being strictly rectified) so I'm assuming the protocols refer to the genotype diet...but can't find any reference in the book.

sorry, Andrea, I missed this earlier post, hence did not answer your question.  I'm not sure how I got the shingles in the first place - my partner had it on his face, but obviously we were very careful to avoid ANY kind of contact...and were also told by doctors that it's not contagious.... ??)

The eye specialists didn't figure out that THAT was my problem until it was too late and there was already scarring to the cornea...too late to treat, and pointless.  So I now have irregular astygmatism in one eye and have to wear glasses all the time.  

That alone I wouldn't mind - but the whole experience has left me with chronic eye problems (burning dryness, chemical sensitivity and meibomian gland dysfunction) which are very hard to live with.

That's the reason I decided to go back to being really strict  with the BTD....hope springs eternal!

Andrea, I thought it was only grapefruit extracts which were interacting with your mentioned stuffs....ouch , sorry eva b I failed here ... :B :P ;) :D....but if you'd ready to go against your treatments, so far have an eye for a good naturopath ;) .....perhaps for long terms a better choice ??).... ;) ;D

preserving what eye function is left would be the goal using phytonutrients.
