Humulin R Humulin N

A: No, you cannot skip even part of your insulin.

Get some R now.

Q: Can I get Humulin N and Humulin R at a pharmacy in the Philippines?

A: I know that in the states you can at least get R insulin over the counter (Every state it seems except PA—Stupid commonwealth…) I would recommend finding a pharmacy or doctor over there and either calling, or emailing. You could probably find a hospital’s email contact pretty easily online. I’m betting that your question for Yahoo Answers is simply too specific to merit any good answers… Good Luck!

Q: I need documentatio and the answer to at what temperature humulin n are r freeze at. ?
I have been keeping the vials in their box and putting in a fridge to go lunch sak next to an ice pack and some believe the insulin will freeze that what. I haven’t been able to find written documentation to say eactly what point the insulin freezes

A: insulin freezes at 32 degrees Farenheit, it should not go below 38 degrees.

Q: difference between humulin n and novolin n?
my boyfriend has been a diabetic since seven years old. He has always used humulin n and r insulin injetctions up until the last month. He has had been changed to novolin n and r, and feels his body is not reacting in a positive way to the change. I need to know if there are any differences between the two insulins that can cause his body to react to any changes in the insulin.

A: My understanding is that they are essentially identical and that little to no changes should be required. Is there a reason he’s still on novolin as opposed to the newer insulins Humalog or Novolog? They are much faster-acting and effective than the older insulins. Much closer to how human insulin works. Have him ask his doc about it. It’s more expensive, but most insurances cover it well now.

Q: what are some alternatives to mixing insulin?
What are some alternatives if a patient is unable to mix their morning insulin? (Type 1) Patient is taking Humulin N 15, Humulin R 5 in morning and Humulin N 7 in evening.

A: N is awful. Get a new doctor.

Seriously, there are so many better options. I did 16 years on N when there were no other options available. Now there are choices. A pump, Lantus, Levimir. Talk to the doctor, or get a new one.

Q: Why do I have to put air into the bottles when mixing insuline (Humilin-R and N)?
I have a 11 yr young Lab who is diagnosed as a diabetic. I could put this question on the dog ‘page’ but thought to have more input here?

I now have to give her mixed shots (Humulin-R and N) in the 70/30 rate, since neither the R nor the N by itself get her glucose down. Her levels keep between 350 and 500 for several weeks now so, according to the vet, giving mixed shots might do the trick. I have been reading up on how to draw ‘from clear to cloudy’ and how to do the ’steps’: put cloudy bottle on table, pull plunger down to let X units of air in seringe equal to amount of cloudy insulin needed without touching the insuling, push air into cloudy insulin bottle, do the same for the clear insuline, then turn clear insuline bottle upside down and pull out needed units and then take the needed units form the cloudy insuline.

My question is that I don’t really get why I have to inject air into the bottles first? What is the purpose of that?
I have to add that with the Humilin-R her glucose level drops from say 394 to 88 or even under and it doesn’t really work too long (done the glucose-curve several times), the Humilin-N keeps her level around 350 and up to a whopping 500, therefore we want to try the mixed shots. Not that it that makes any difference for the question, but maybe people have some general advice for me concerning using mixed insuline?

A: Injection of air into the insulin bottle in the amount of units that you are preparing to give helps to ensure that the right amount of insulin is then easily withdrawn without bubbles, as it creates air pressure in the vial when you tip it upside down to withdraw the insulin.

Q: Any Docs or Nurses know the answer to this insulin question?
It’s been a while since I’ve been back in the profession and going back. Obviously, one of these questions is wrong on this open book test. Anyone know and why your answer is right so I will be aware in the future?

Which is an incorrect order for insulin?

A. 5 units Humulin R subcutaneously now.
B. 10 units Humulin R subcutaneously every AM.
C. 30 units Humulin N subcutaneously every AM.
D. 60 units Humulin R subcutaneously now.
I think you’re right MS3. Your answer was my first impression and now that I recall, a sliding scale doesn’t even allow 60 units! If someone needed that much insulin they probably need to be on an IV drip cause their blood glucose would be well over 350 minimum. Its been 2 years since Ive been out of nursing and going back. It will all come back to me. Thanks for your help!

A: Many type 2’s take 60+ units at a time.

When I was pregnant I was taking over 300+ units a day.

So you see, it is not unheard of.

Q: when switching from nph insulin to 1 a day lantus is there apecial way to do it and we re a little nervous abo
my husband has been on insulin shots for 13 years, humulin n and humulin r new dr. put him on lantus one shot at bedtime and Avandamet2mg/1000 2 x daily. little nervous about change over. he works contruction and burns alot of carbs all day . guess we just need some more direction than we were given

A: A combination of Lantus and Avandamet may give him more consistent blood sugars during the day.

I’d suggest that he do finger sticks fairly often during the first few days at work, to see where the sugar is running. Just in case, have him carry some glucose tablets. Then, let his doctor know the readings.

As you know, consistently “normal” blood sugars help prevent/minimize the consequences of diabetes.

Good luck.

Q: Mixing two types of Insulin, Need Help. Please!?
Hi all,

I am Type-1 Diabetic patient and recently I have started using Insulin. First, I was prescribed Humulin 70/30 but my blood sugar was not adjusted.
I was then prescribed with Humulin R and Humulin N to be mixed together. I notices that Insulin R was working better than N.

Now I want to ask another question.

Are there any patients that are mixing Humalog/Lispro with Insulin R or Just using Humalog/Lispro alone. Can I control my sugar better with these two or single alone?

My readings are either in 250mg/dl+ or as low as 50mg/dl. I want to stabelize my blood glucose level

Please help me out! There is no specific diabetic guidance centers in my country, My only hope are you people with experience.

I am 22yrs old.


A: What? There are no specific diabetic guidance centers in America? You’ve either got to be joking, or you’re not aware of where they’re situated.

First of all, Humalog/Lispro is what’s termed a bolus (fast-acting) insulin, which is taken at times of eating. This would not give adequate cover unless you were using a pump. (With a pump, insulin is infused continually over any 24-hour period so there’s no need for a longer-acting insulin.)

Humulin R has a period of action that lasts anywhere from 4 to 12 hours, so it may not be providing you with a long enough duration of operation to act as a normal basal rate of insulin would. (The basal rate is equivalent to the tiny amounts that a healthy pancreas would be offering to the system over any 24-hour period.)

You’re obviously being prescribed your insulin from a doctor somewhere, so I’d advise you to go back to that doctor and explain the sorts of blood sugar levels you’re getting. (I’m sure you already realise that blood sugar levels of 50 mg/dL are too low, and you, undoubtedly, need to take remedial action to prevent you slipping further into hypoglycemia.)

Put simply then, having been diagnosed as type 1, you will, unless you’re using a pump, need to have a combination of two insulins … the longer acting one to act as a basal dose, and the shorter acting one to act as a bolus dose.

I wish you the very best of luck in getting your doctor to review your medication.

I hope you have a long, happy, healthy, and trouble-free future.

Q: Can you sell Insulin you no longer use?
My husband was given a new prescription and is no longer using his humulin N & R. We have over 10 boxes that are sealed and haven’t been touched so i was wondering if it was allowed to sell them or just throw them out and waste 200$+ worth ….We contacted the pharmacy in wich he bought them but they told us they could not be reinboursed :(

A: It’s against the law to sell someone a prescription drug unless you have some sort of license to do so. You could ask your church or even a clinic about donating them.

Q: I am confused about insulin pens.?
I would like to switch to using an insulin pen, preferably one that uses the BD Ultra Fine III Short Pen Needles (or equivalent). I want a fast-acting insulin. What I am really confused about is the difference between Humulin N and Humulin R, mainly the difference in how quickly they work. I would prefer to stick with Lilly, as they make my other pen, Byetta, and would likely use the same type of pen needle.
I have discussed this with my doctor, she just wasn’t sure which types of insulin are available in a pen. She agreed with me on using fast-acting, and it will only be used as a back-up to the Byetta. This is just a matter of finding the type of insulin we are looking for in a pen. So far, the Humalog sounds about right.

A: R is short for regular. It is equivalent to the insulin that comes from the pancreas. It starts working in 30-45 minutes, peaks at about 1-2 hours, and lasts for about 4-6 hours.

N is short for NPH. It is regular insulin suspended in a special solution to make it absorb more slowly. It peaks in about 4-5 hours, and lasts for about 8 hours. This is used for basal insulin, usually 2 times a day. It’s absorption can be very irregular leading to wide swings in sugar.

Humalog, also made by Lily, is human insulin with 2 of the amino acids switched. It starts working in 15-20 minutes, peaks in about 1 hour, and lasts for about 3-5 hours.

Lantus is a long acting, “peakless” insulin that you could take once a day for basal insulin.

Q: Need more help with this Medication test question?
Which is an INCORRECT order for insulin?

A. 5 units Humulin R subcutaneoulsy now
B. 10 units Humulin R subcutaneously every AM
C. 30 units Humulin N subcutaneoulsy every AM
D. 60 units Humulin R subcutaneoulsy now

A: B seems OK, you could give regular insulin every morning with breakfast for example, although it’s not written QAC…. but 60 units is a LOT of regular insulin and wouldn’t usually be given all at once like that, even if someone was in DKA, they’d be put on a drip instead. I think D is the wrong order.

Q: when using Humalog what do i do if i want to have a snack?
I have been using Humulin R and N Insulin for 15 years and just started using Humilog and Lantis insulin today. The Humulin stays longer in your system so having a snack is not a problem. I was thinking that if Humilog works in 15 min. and then leaves your system in about 1-2 hours what happens if I want to have a snack? Do i have to take another shot to eat a piece of friut in the afternoon?

A: Glad you’re using the more modern insulins…you will notice a big improvement in your BG’s by not having that “peaking” action of the old insulins. Whether you take an injection for a snack depends on the amount of carb. For me, anything over 5g of carb needs insulin to handle it. So for a piece of fruit, yes you’ll need to bolus for that.

Q: Insulin brand difference?
For a year now I have been using Humulin N (cloudy) and Humilin R (clear) mixed in into one syringe. Yesterday I surprising ran out of N, and since it was really short notice I couldnt get any more shipped to me from my prescriber right away. So I went to a local pharmacy and they gave me Novolin N. I used to use Novolin back in the day, but with Novolin R. Now I need to know if its okay to use Novolin N and Humulin R mixed together until I get more Humulin N. Like is there any difference between the two brands besides just brand names? All I know is when looking at the new bottle of Novolin N and an old empty bottle of Humilin N, they both say “NPH, human insulin (rDNA origin), isophane suspension” somewhere on the bottle. Although that makes them seem like the exact same thing, I need to be sure that they will work the same.
If anyone can help me thank you so much!

A: Chemically, there is no difference between the two. When used properly, both will give you excellent results.

But you should call the pharmacy (or your doctor) to see if maybe the DOSE needs to be differnet, due to different concentrations if drug uin the bottle.

In the mean time, keep a CLOSE watch on your blood sugar levels! Don;t let them get too high or too low.

Q: 2 questions about Insulin for Diabetics?
1) A diabetes poster that I am studying says Regular insulin (Humulin R, Novolin R) and intermediate acting insuline (Humulin N, Novolin N) are OTC (Over the Counter). Could this be a typo???
I thought all insulins are obtained by Rx (prescriptions) here in the United States of America.

2) The poster also goes on to say that the usual daily dose of insulin for Type 1 DM is calculated as: 0.7-2.5 unit/kg/day
But I thought I learned in school the daily dose of insulin for Type 1 DM is: 0.5-0.6 unit/kg/day.
HOWEVER, for Type 2 DM, it is: 0.7-2.5 unit/kg/day
So, which is right?

Someone please get back at me. Thank u!

A: I have to have prescriptions for all of my insulin. And as far as dosage, every person’s disease is different. How much insulin a person has to take depends on their personal needs. I know people with type 2 that take 100 units of Levimir every night and day time insulin that is adjusted by what and how much they eat. Others that I know take only 20 units a night and none during the day. So, I think the poster is all messed up.
