Conversion to humulin

I would be interested in hearing about peoples’ experience in converting
from beef/pork insulin to humulin.  Any complications?

Thanks,

    I switched from NPH to Humulin N about a year ago and have noticed no
    difference whatsoever.

    I was only on beef/pork for about 6 to 8 months after I was diagnosed
    eight years ago.  When I switched, I had no problems but my doctor told me
    that *some* people have more difficulty detecting an oncoming reaction
    after switching.

    The problem lies in how brittle a diabetic is.  A brittle diabetic is
    one who is quite sensitive to getting their level of insulin activity
    to just the right level (+ or – 2%).  These are typically the most
    "insulin dependent" of diabetics.  On the other hand, there are many
    so-called Type II diabetics who do in fact take insulin who are
    quite insensitive to the actual amount of insulin they take, often being
    able to vary their dosage by as much as 50%.

    Now one of the oustanding features of "humulin" is that it tends
    to go off with a bang in the first half of its lifespan, and then
    steadily retreat in the second half.  For a less than brittle diabetic,
    this presents no problem.  But for those who are really brittle (and
    these are only a single-digit percent of diabetics), this variation in
    insulin activity knocks them for a loop.  Their blood sugar levels,
    when they try to use human insulin, can never stabilize.  Such patients
    find that animal-derived insulin is much more even in its onset and
    duration of insulin activity.  These people would be well advised to
    stick with what they are using.  How does a person know if they are
    a "brittle" diabetic?  By the fact that the adjustment of their
    insulin dose is critical.  Too much gives them hypoglycemia, too little
    will plunge them into ketoacidosis.  These people should not pay any
    attention to the fact that more "stable" diabetics can do well on
    human insulin.  "What’s great for the Russian is death for the
    German", as the saying goes.  Not everything in medicine is right
    for everyone either.

    Joe,

    Are you a Type I or II?

    Dave, Dave, put that soap box away, Joe Esak was just answering a question
    and he was very kind to do so.

    Alright let me put the soap box back in the corner.

    Leon, I’ve expounded on that letter I sent you.

    When Leon asked his question about differences it was with regard to his
    Type I wife, who has been diabetic for 27 years.

    The issue for conversion from animal to human insulin is important for
    type I diabetics and their basal insulin dose. I tried converting from
    pork NPH to humulin NPH. There is a world of difference between them.

    Human NPH has a peak at 6 hours wheras pork NPH has a peak at 8 hours.
    More of the Human NPH is in the blood stream sooner than 6 hours,
    which gives an increased tendency for lows, if you take it for nighttime
    basal control at 10 PM. The natural low point being at 3 AM. Most of my
    basal control human NPH was used before 4 AM, but I NEED the insulin
    between 4-8 AM. This is just the time the human NPH drops from its peak.
    Pork NPH hits its peak at 6 AM eight hours after my 10 PM dose and right
    in the middle of my peak insulin basal needs aka dawn phenomenom.
    YMMV (Your Mileage May Vary) I’m neither a doctor nor
    the town bum (c’mon Dave you’ve been accused) ah to dream……

    I don’t feel the human NPH lasts the 20-21 hours that pork NPH lasts.

    Why manufacturers are allowed to say that it is NPH or Ultralente is beyond
    me. They are different drugs, when you run tests on Type I diabetics without
    any insulin resistance. Testing Type II diabetics for the efficacy of the two
    drugs is not relevant to a Type I population. Type II more commonly have
    insulin resistance problems, where the Human insulin will always work
    better to treat the patient.

    For Pre meal boluses I always use Humulin Regular and I’m waiting for
    Lyso-Pro to gain approval.

    The scene with Ultralente is more varied, I’ve never tried converting to
    Human Ultralente. I was on pork Ultralente for the nine years I was in
    the DCCT. My DCCT nurse Mary Larkin, says human Ultralente has a definite
    peak and only lasts 36 hours though the pork Ultralente is flat with a very
    slight peak and last 48-60 hours.

    One of the later posts said only "brittle diabetics" will notice a difference.
    Neither I or my doctor would qualify me as "brittle" in any way shape or
    form. I have a fearsome dawn phenomenon where I’ll tie/adjust my 10 PM
    basal dose vigourously to the days exercise itensity/duration. I could take
    the beef/pork NPH as an alternative to Pork NPH, but I’ve never beleived
    in changing something just for the sake of change.

    Well… sort of.  I switched about four years ago and I’ve heard from others
    that my experience was not unique.  What happened is that it became very
    difficult for me to realize that I was low.  A few times I had no idea that I
    was low until I was starting to pass out.  After a few months I guess I
    readjusted and either became more aware of my lows or whatever had suppressed
    the symptoms disappeared.  I don’t know which.  Anyway, I know of at least two
    other teen Type I diabetics that this happened to.  (For info: I’m 20 now and
    have had Type I for 13 years.)

    Either your nurse got her numbers crossed up, or you have failed to
    remember them correctly :-) .

    Human Ultralente is specified as lasting "up to 24 hours", but experienced
    users report that it isn’t active past 20 hours.

    As for animal Ultralente, the timing specs are only "up to 36 hours".  It
    has never been known to last anything like the 48-60 hours you state.
    (I have used this form of insulin for most of my past 30 years of diabetes.)

    >One of the later posts said only "brittle diabetics" will notice a difference.
    >Neither I or my doctor would qualify me as "brittle" in any way shape or

    I don’t remember stating that "only" brittle diabetics have problems
    with "bug" insulin.  What I meant is that brittle diabetics should
    be advised of the inherent difficulties that "bug" insulin will give
    them.

    Why does everyone keep chanting "Multiple Injections… Better Control",
    when if you use an insulin mixture elaborated to give smooth insulin
    activity for an entire day and well into the next to overlap smoothly the
    startup of the next day’s injection, you can avoid all this nonsense
    like "dawn phenomenon"?  I take an animal insulin that I have to buy
    and import from abroad that runs so smoothly, I scarcely know it’s there.
    Yet my bg’s run in what I consider very acceptable levels (below 130 mg/dl).
    And please don’t tell me that I’m some kind of exceptional case.  When
    I take the slop (bug insulin) that you people are forced to take, I
    practically die (bg’s running from 50 to 500 and back every day).

    You’re just being taken in by the insulin companies (Lilly and Novo) who
    are determined to sell you an inferior product.  Years ago, both of these
    companies used to make and sell here what I now have to get from far
    away.  Their insulin, when they made it correctly, worked just as good.
    The profit motive propels them in their quest to get everyone over onto
    this horribly inferior product, "bug" insulin.  Bug insulin wasn’t supposed
    to turn out like it did… it just happened that way by unforeseen
    circumstances.  As for the DCCT, all that it showed was that tighter control
    yields fewer complications.  (People who believed otherwise before the
    DCCT were just kidding themselves.)  The DCCT did NOT prove that
    multiple daily injections were incontrovertibly necessary to obtain tight
    control.  But once insulin was no longer available in the USA that would
    run for an entire day cycle of a person’s life, that is why it became
    necessary for multiple injections, not for good control per se.  Bug
    insulin simply could never be made to last enough past 24 hours.  Then
    in 1985, Lilly and Novo made the daring move to cut the action of the
    animal insulins NPH and Lente down from almost 30 hours to barely 24 so
    that the animal insulins would no longer be advantageous over the greatly
    shorter "bug" insulins.  They did this so that they could get more people
    to use the "bug" insulins so that they could recoup their development costs
    on this new product (cost: more than a billion US dollars).  Also, the
    actual production cost of "bug" insulin is much less than for animal
    insulin, which does need several purification steps.

    So much for the "bug" insulin conspiracy.  It is real, and yet so many
    diabetics and their doctors have been totally taken in by it.

    Yes, I’ve had lots of complications.  I was on the Beef Ultra Lente for
    several years, had the best contol ever (I’ve been diabetic for 36years –
    type1) .  Now that I have to take the humulin u.l., I have been having
    terrible insulin reactions.  Awhile ago when I was walking into a store,
    my eyes could only see a light with darker colors on the perimieter.  This
    would last about 30 sec. , go away, and come back again.  I was low, had
    something to eat, and it went away.  I’ve also been low and not even known
    it.  My bl. sug. would go to about 43 before I realized I was low.  I am
    currently trying to get people to call NovoNordisk and Eli Lilly to "bring
    back the beef".  I hope I can reach enough people to make it happen as it
    did in Great Brittain.

    Mickey,

    I agree 100% with you on mixing various insulins to gain excellent
    control.  There is no need for taking multiple injections to gain "tight
    control," if everyone would just use an animal-based Ultralente.  It is
    the secret.  My 9-year-old daughter has had Type 1 diabetes since 20
    months.  Contrary to the drug companies’ recommendations, we have been
    mixing Humulin R, Humulin N, and Novo-Nordisk Beef Ultralente in the SAME
    syringe for years, and it works beautifully.  The Beef Ultralente works as
    a wonderful baseline insulin and we adjust the other  two according to her
    meals and schedule.  Her doctors are amazed at the results.  Her A1C is
    always between 4.5 and 5.6%.  Her last one was 5.5%.  She eats pretty much
    what she wants to.  And, most importantly, she has NEVER had a
    middle-of-the-night reaction.

    She takes just 2 shots a day:   basically, 4-1/2 Humulin R and 9-1/2
    Humulin N
    in the morning before breakfast, and 5 Humulin R, 2-1/2 Humulin N, and 10
    Beef Ultralente before supper.  (There is no need to split up the
    Ultralente, since there is no peak).  I will put her blood sugar control
    up against anyone else’s.

    Now, I am really scared about not being able to get the Beef Ultralente
    anymore.  I have stockpiled about 8 bottles in the refrigerator which
    should last until this summer.  Then, we will just have to experiment.  My
    friends’ children who have tried the Humulin Ultralente didn’t have the
    same results.  I think it acts like a glorified NPH — it still peaks, it
    has a much shorter onset, and does not act as long.

    You have an interesting theory on the "drug company conspiracy."  I
    wouldn’t doubt it.  It is definitely not to their economic advantage to
    continue marketing the animal insulins.  Do you think there is a
    distributor in the U.S. that could get FDA approval to distribute the
    animal insulin from that company in England or elsewhere?  Please keep me
    informed.  I think you have my address.

    Thanks.

    Several years ago I was on Beef ultralente — three shots, with one
    big ultralente shot in the morning.  I found (and later my doctor
    verified [too late]) that ultra DOES peak if you give enough of it.
    And since it’s ultra, the peaks last a really really long time (I
    remember having low blood sugar for a couple of hours regardless of
    what and how much I ate!).  I fixed this problem by re-distributing
    the ultra into two shots and that seemed to do the trick, even though
    it’s so long acting (and they work on top of each other).  My
    understanding is that it’s not a problem until you give too much of
    it, and then, *pow*.  In any case, probably not a problem for your
    daughter, but something you (and she) should probably know.

    It is interesting, but I’ve changed over to Humulin b/c I had some
    pretty bad night (and day) reactions with beef and beef-pork.  With
    humulin I have had *no* night-time reactions where I didn’t wake up
    and I can function much better at a much lower blood sugar level.  The
    downside (for me) is that I have a much harder time diagnosing when I
    actually get low.  I don’t think that I would ever go back to
    beef-pork, even with the longer acting ultralente…  (as a side note,
    I stay in pretty good control; avg. blodd sugar around 100-120).

    That’s easy,  In fact it is rapidly becomming the only company in the world
    producing animal insulin (Which is why I have their address on disk)

    You might want to make sure that the keeps this address as they are now

    You got that stright. Some can not take animal, Others nothing but

    Some like nice short quotes to remind you what they are talking about

     you can find one with the same calibration code (i.e. the 3 letter & digit
    code found on the strip insert such as "23d") that will do.  The sticks
    contain no more information than that 3-letter code.
