Q: What is the difference between Humalog and Humalog 75/25?
I know that Humalog 75/25 is a mix. time delay or something, but what is the difference with just Humalog? can it be taken in the same way as the Mix? Does it need to be mixed with something in order to take?

A: Humalog 75/25 means that 75% of the mixture is long-acting insulin (same insulin except it has protamine added to make it act over an extended period of time), and 25% is short-acting.
Mixtures like this help keep tighter control of blood sugars because it sort of covers all bases – the quick coverage for your next meal (if you take it right before you eat) and the longer, steadier coverage to last all day.

Q: Where can I get cheaper Humalog insulin?
I have been a diabetic for over 12 years now and recently my doctor started me on Humalog insulin which has worked pretty good so far BUT, it is very expensive. I have insurance but even with my insurance I pay about $150.00 every three weeks for two viles. It adds up and I need this to live so I am wondering if anyone knows of any coupons or has any advice as to where I can get this insulin for a less expensive price. Thanks!

A: They might have it here, though I am not sure

Its were i get my test strips.

Q: What happens to humalog insulin when it goes past its expiration date?
I assume it would just stop working, or are there other effects? Like instead of working right away it works on a delay?

A: Your right it just loses its effectiveness. Never use it because it can be harmful. I have had juvenile diabetes since i was 4 and once i accidentally gave expired insulin, i ended up in the hospital.
Just throw it away before it comes too close to expiration date and don’t leave it in the sun either.

Q: What is the difference between Humulin and Humalog?
Are these two types of insulin very different?

A: Both of the above are incorrect. Here is a more comprehensive chart of insulin types:

RAPID ACTING: (3 times/day)

Regular Insulin
Humulin R
Novolin R

MEDIUM ACTING: (2 times/day)
NPH Insulin
Humulin N or L
Novolin N or L

LONG ACTING: (once a day)

Along with these there are a variety of premixed insulin types available. These premixes include a rapid/short acting insulin along with a medium/long acting one.

NPH & Regular:
Novolin 70/30
Humuiln 70/30
Humulin 50/50

Lispro-Lispro Protamine:
Humalog Mix 75/25

Aspart-Aspart Protamine:
Novolog Mix 70/30


Therefore, the differences between Humalog and Humulin are many. Humalog is a rapid acting insulin. Humulin can be either rapid or medium depending upon whether it is R or N. Humalog is dosed three times a day with meals. Humulin N is usually dosed twice a day or maybe once a day if newly diagnosed.

Overall, insulin dosing is very complex and can become quite complicated. It is important to follow the schedule that was set by the doctor.

Q: Are you a type 1 Diabetic using Humalog penfill? How do you find it?
I am currently taking Toronto regular insulin for the last 20yrs.My Dr. reccommended Humalog for better control and change.

A: I always just got mine at the pharmacy.

Q: Exactly what is a 3ml Pen for Humalog 75/25? How would I find out how many units is in each Pen?
I am looking for a way to find out how many uses is in 1 Humalog 75/25 Pen 3ml.

A: 100 units per every 1ml -millileter same as CC -cubic centimeter

so you have 300 units there of an insulin mix

Talk to your doctor about how many units per use and how many for correction of high blood sugar. Don’t worry, it should get easier with time…

Q: How exactly does Humalog work?
I have been on Humilin 70/30 but my uncle passed away recently and my aunt gave me his insulin pens which are Humalog. What’s the difference? I’m thinking it works right away, is this correct?

A: Do you use a Humulin or a Humilin?
Let me suppose you use humulin. Humulin 70/30 is made by eli-lilly, it is a mixed insulin with Humulin N 70%+Humulin R 30%.

The major different is an action.
Humalog is also made by eli-lilly but it is a rapid acting insulin. It has onset <02.5~0.5 hour, peak 0.5~2.5hour, effective duaraion 2~4hour.
R is a short acting insullin. It has onset <0.5~1h(hour), peak 2~3h, effective duration 3~6h.
N is a intermediate acting insulin. It has oneset 2~4h, peak 4~10h, effective duration 4~16h.

If you want to use humalog, you have to use it with humulin N or for an additional shot when you are hyperglycemia only.

If you need more help or if you want to change your prescription, ask your doctor.

Q: What’s the difference between humalog insulin and humalog lispro insulin?

A: lispro is short acting insulin i.e its effect is for 6-8 hours only then another dose is required…whereas normal human insulin is intermediate acting , works for 12 hours.

Q: How much does a vial (10ml) of humalog insulin cost in india?
Also whats the specific name of insulin syringe to be used?

A: nike9,
Might I suggest thsat you research your answers at this link

Hope this helps

Q: What happens if i mix Humalog and Lantus together?
I have always been told that mixing the two is bad, but i can find anything one what it does to your body. Could some one please help me find this out? Thanks:)

A: generally, if you mix two insulins with different action times, you alter the respective time of each, causing one or both to peak early and might result in a hypoglycemic episode.

Q: What happens if you use the same needle to inject Humalog and Lantus but at different injection sites?

A: You could easily contaminate both bottles causing the wrong dosage of the correct insulin. Also a needle dulls very quickly and hurts more if you use the same needle twice. In an emergency it is better to have the insulin instead of going without but I do not suggest making a habit of using the same needle more than once.

Q: How much does humalog and lantus cost?
i’m 20 and have had type one diabetes for 10 years. I’m wondering how much insulin would cost with out insurance because I might possibly be without it soon! So i wanted to know if anybody knew how much lantus and humalog would cost without ins. I have perscriptions for it right now..but my ins. is done at the end of March…

A: I have never purchased the humalog but I know that lantus is about $100 at our Walmart.

Q: Do I use the right dose of Lantus and Humalog insulins?
I am a case of IDDM i intected 55 unit mixtard 30/70 two times per day. Now I shiftted to Lantus and HUMALOG. I inject 28 unit Lantus AT BED TIME AND APROX 5 UNIT HUMALOG AFTER BREAKFAST 8-10 UNIT HUMALOG AFTER LUNCH AND DINNER .Do I USE THE RIGHT DOSE? MY BS IS IN normal range.Have you any recomendation for me?

A: The best advice I ever got about this was that your blood sugar in the morning should be the same as it was before you went to bed, because this means that your background dose (lantus) is right. You should ask your dr about carb counting or dafne courses if you have type 1 diabetes as these can help you to get your control better and mean that you have heaps more freedom about what and when to eat. But if your blood sugars are ok then that’s a pretty good sign your dose is right for you. I now use a pump but you’re on almost exactly the same as what I took when I was on lantus/humalog. Remember everyone needs different amounts of insulin depending on their metabolism, diet, level of exercise etc. – it’s really a case of trial and error to find out what’s right for you, but if you’re blood sugars are good and you’re not feeling ill (esp. if you’re not feeling like you’ve been hit by a bus in the mornings as this means you could be hypo during the night and might need to reduce your lantus dose) then don’t worry – you’re doing better than most! Hope that helps – good luck xx

Q: Difference between Novolog and Humalog insulin?
I know that they are both “fast acting” in oppose to regular and NPH insulin. But is there any differences between the two and how they break down carbs, effective ness etc?

A: Like Regular, Humalog and Novolog are used to cover meals and snacks. Most meals raise the blood sugar for only 2 to 3 hours afterwards. Once injected, Regular insulin takes 30 minutes to begin working, peaks between 2 and 4 hours and hangs on for 6 to 8 hours, long after the meal stopped raising the blood sugar. Humalog and Novolog, on the other hand, begin working in about 10 minutes, peaks at one to one and a half hours and are gone in about three and a half to four hours.

Many people who’ve tried these faster insulins report that their control is improved and that they feel better. The great advantage of fast insulins are that they match the “action time” for most meals. You can take them as you begin eating, rather than the 30 to 45 minutes prior to eating required of Regular. No longer do you need to accurately anticipate when you (or your young child with diabetes) will begin eating. In addition, Humalog and Novolog leave your body faster so you don’t have residual insulin causing low blood sugars in the late afternoon or, even worse, in the middle of the night.

For most meals, fast insulins will be lowering the blood sugar at the same time the food is raising it. The rise in the blood sugar seen in the couple of hours after eating is much lower, especially with Novolog, and by the end of three hours the blood sugar is often back to its starting point.

With Humalog or Novolog, you’re better equipped to prevent spiking blood sugar between meals, while avoiding the lows that result from the combined buildup of Regular and long-acting insulins. The new Lantus insulin is an excellent choice when using these fast insulins to cover meals. The clearly defined action times for the fast insulins makes it easier to correctly adjust meal doses.

Humalog and Novolog are also excellent insulins to use to lower high blood sugars. Their faster action means that less time is spent at high blood sugar levels, and there will be less residual insulin triggering low blood sugars later.

Humalog is produced by Lilly and was first released in the U.S. in 1996, while Novolog is made by Novo Nordisk and was released in 2001. Both insulins offer quicker action time than the original “short-acting” Regular insulin, which first became available in 1921. However, users also report significant differences in activity between each of the three insulins. Let’s first look at these differences.

couple of major differences are being reported by users between Novolog and Humalog. Especially among pumpers who switch from Humalog to Novolog, reports have surfaced that Novolog appears to be both stronger and quicker than Humalog, and doses have to be cut in order to prevent hypoglycemia. Dose reductions are often in the 10% range, and it may be wise to reduce doses right away to prevent unwanted lows. If, instead, blood sugars rise, doses can always be raised again.

Novolog also starts working faster than Humalog. Although no direct comparison of Novolog and Humalog has been reported, one research study found that in normal individuals, Novolog reaches peak activity at 52 minutes, compared to 145 minutes (2 hours and 25 minutes) for Regular insulin. Humalog peaks at about 75 minutes (Eur J Clin Pharmacol 1999 May;55(3):199-203). Both pumpers and injectors may note lower post-meal readings due to the faster onset of action.

The clearly defined action times of the fast insulin makes it easier to troubleshoot problems. For information on how to determine the number of carbs covered by each unit, see the 500 Rule in the Pocket Pancreas. Humalog and Novolog are also excellent for lowering high blood sugars with less time spent at high blood sugar levels, and less residual insulin left to trigger low blood sugars later. For information on how to safely lower highs, see the 1800 Rule, also in the Pocket Pancreas.
