Redheads need more sedation than other hair colors?

I read a study online that said redheads need more anesthesia, novacaine, and sedatives than those with other hair colors.  I have found this to be true at the dentist.  They always need to give me more novacaine than other people.

In March, I had a colonoscopy where my doctor gave me a large amount of sedative, however, I woke up several times during the procedure.  Each time they gave me more sedative.  Finally, after waking up again, my doctor said she couldn't give me anymore and I would just have to be awake for the procedure.

Today, I had a follow-up colonoscopy based on some findings of the last one.  I told the nurses what had occurred last time, and how I definitely wanted enough to sleep through the whole thing.

Once the nurses got my records and saw the dosage I was given last time, they couldn't believe 1.  that I could have been given so much and 2.  That I was still awake.

I told them the theory I had read online, but none of the nurses had ever heard of it.  Thankfully, today they gave me the extra large dose at once, so I did go to sleep instantly and didn't wake up.

So, my question is if you are a redhead, have you found that have needed more novacaine at the dentist, or more sedation during a colonoscopy (or other procedures)?

I was born a red head but my hair changed to brown and now I dye it back to red so I don't know if this would still apply to me but yes, I have to usually have twice the amount of novacaine and sedation because I metabolize them to quickly. I don't know if it's because I'm a red head (never heard of this theory) or the fact that I have a fast metabolism.

Wanna hear something funny?  This is also seeming to be true with Horses... Horses such as Red roans for example, seem to need more sedation than regular brown or white, black horses, etc.. even Palomino's too... At least this is according to my equine dentist...

 

  I'm sure that it's not the case for every reddish horse, but that seems to be more the case for horses that have the red gene than for horses that dont.

Interesting. I get more sedative for a c-scope and am still awake. But I think it's because I want to be. Regarding pain meds, or other stuff, I don't seem to need more.

Oops...I'm not a natural redhead, but it does run in the family...maybe that doesn't count.

Still intresting stuff, however.

I think redheads have worse luck when it comes to health...I saw or read somewhere that there's a condition where people can be overweight from a very young age, and it strikes reddish/very blond people disproportionately. So it doesn't surprise me to hear that redheads would need more sedation, too.

Thanks for posting those articles Seconder.  I actually had to go to the dentist today (yesterday...colonoscopy...today...dentist...I am knocking out all of my dr.'s appts this week.    Just like in that study (in one of those articles) I, too, fear the dentist and have had several bad experiences.  I have to go next Wednesday for some major work, so I asked my dentist if he had heard of the study...and he had!  He promised they wouldn't get started until I was completely numb.

I am going to print out those two articles for his office

OK, next question.....how many of you readheads are left-handed?
