Reviews for Novolog

Anonymous · August 5, 2011

For Diabetes, Type 2 "After trying several insulin types of medicines which caused severe itching, I was put on Novolog 70/30. At first there were no side effects, then dizziness started to occur and its getting worse, my ankles are starting to swell and I am putting on weight. I'm at my wits end. Novolog is very convenient to use, but unfortunately now I have to go back to doctor and start a new medication and go through trial and error with a new medication which can also be very costly."

Painful · Taken for 1 to 6 months · July 6, 2021

For Diabetes, Type 2 "On bolus regimen (rapid + long acting) since early 2021 and developed painful neuropathy in thighs/legs that is worsening to the point of insomnia. The sharp pains sensations feel like sewing needles. Doctor didn't know the cause, and want to test thyroid which was negative when hospitalized for DKA. It is always best to read package insert from the manufacturer because it contains more detail. I learned all insulin products reduce potassium levels (low K can cause muscle cramps, burning, even death) and rapid glycemic control is "associated with" transitory eye refractive disorder, worsening retinopathy and "acute painful peripheral neuropathy". This has another name: Treatment-Induced Diabetic Neuropathy. I believe PN becomes chronic once it starts as long as you're using Novolog."

For Diabetes, Type 2 "I put on A LOT of weight with this novolog insulin. No diet changes, but gained 60 lbs in a year. I was taking 15 units 3x a day. I kept hearing "hang in there". "give it time to adjust to your body." So now, my blood sugars are worse thanks to the extra weight, thanks to Novolg flex pen. I also experienced not urinating enough, & ankle swelling. Probably because this stuff won't let you urinate. Did it lower my blood sugar? Of course! It's insulin. But at the cost of putting on 60 lbs? Not worth it. I finally stopped it even though my idiot doctor disagreed. Yeah, Doc, I'll keep taking it until I can't fit out of my door way. Ridiculous! I worked hard to lose 60 lbs."

For Diabetes, Type 1 "Novolog works very well and very fast (3-5) hours in lowering sugar levels but for those w/out insurance be wary Novolog is very expensive, espicially when you have to couple the insulin w/ another slow-acting, such as Lantus. Together these are very effective however."

For Diabetes, Type 1 "This insulin is terrible. My boyfriend almost died today because he took the normal amount of insulin and it was too much for his body and his sugar dropped to 26. When your sugar is that low it can cause fatal symptoms including passing out, disorientation, memory loss, seizures and even death. My boyfriend ending up an hour away in the middle of nowhere and he was lost. He was passed out and almost died it was lucky his parents found him. SWITCH brands this insulin is too strong and has too many side effects. My bf got lucky today maybe he won’t next time...."

For Diabetes, Type 2 "Have used Novolog for 9-10 years. I has reasonably helped with controlling my glucose but has caused considerable weight gain. My units are determined by the carbohydrate count per meal - that has been adjusted from a ratio of 10 to a ratio of 7 per unit. A new endocrinologist has suggested Januvia but the side effects sound horrendous. The other 5 oral medications I've tried over a period of years did nothing positive and actually caused too many gastrointestinal problems. Will decide in 3 months, at next appointment."

For Diabetes, Type 2 "I take a combination of Novolog R and N. It has worked just as well as the High dollar medications that I had taken in the past. I was taking some high dollar medications and always ran through my insurance coverage after 6 months. After moving back to Kansas from Missouri my specialist here changed me to the Novolog regimen which is all out of pocket but cheaper than 6 month of out of coverage for the high dollar medication."

For Diabetes, Type 1 "I was put on Novolog when I was diagnosed with Type 1 and have loved it ever since. I've never had any negative side effects and when coupled with the Omnipod it is phenomenal for me. It is important to note however that every person's body is different. My doctor recently had me try Humalog to which I had multiple negative side effects. This does not mean one is better than the other, just that for my own body the Novolog happens to be what it accepts and works with best. You should always tell your doctor how ANY medication makes you feel if you experience negative side effects. For me, the Novolog is a gods send and I love it :)"

For Diabetes, Type 2 "I assume the Novolog insulin is doing what it is designed to do, my complaint is with the delivery pen!!! It gets stuck and will not plunge thereby leaving the insulin unusable. Humalog has a better pen!!!!!"

For Diabetes, Type 2 "Been on Novolog a month, also using Basaglar 30 units a day and Metformin ER. A1c too high at 9.1 so doctor told me I needed to try short acting insulin. Costs is high one pen as $107 I pay $325 for 5 Basaglar pens. Seems like this disease is making drug companies wealthy. I do see improvement when using the Novolog when I take it at big meal when carb intake higher. Has improved fasting levels. But the cost will prevent me from sticking with it. Insurance pays some I hope but I went off Lantus because of costs. I think Lantus worked better then Basaglar but that's just my own observation and experience. I've tried Januvia, Starlix, Victoza, and none really work consistently even being on a low carb diet. Besides the insulin is affecting my weight in a negative way which can't be good for insulin resistance. After awhile the injected insulin probably also become resistant to cell intake. So then you take more and more. Yeah a expensive band aid for a disease that fights back."

For Diabetes, Type 1 "Any fast acting pen that fails to act even one time is a total loss. This Novolog pen fails to inject sometimes. So I rate it 1/10. What happens is: you put the flex pen on and click it into place, and then whatever amount you dial does NOT infuse after injection. So even though it works well when it works, not working even once when you absolutely need it makes it a terrible device."

For Diabetes, Type 2 "I use both Novolog and a slow acting insulin. At first Novolog worked pretty well after meals but then I started to see a delay and a continued spike after two hours. I have seen improvement in fasting BGL but I have also gained back some weight I had lost just on the slow insulin. Using fast acting insulin is more frustrating because it adds in more monitoring on BGL and you risk injecting too much causing low blood sugars. I just think your best trying to avoid using insulin as long as you can because it is sort of a grind to start using insulin."

Truth2021 · Taken for 10 years or more · September 14, 2021

For Diabetes, Type 1 "I was diagnosed with diabetes in 1994. Began using Novolog. It worked great. Years later, my insurance told me I could no longer use Novolog, it was "premium". I would have to pay 2x as much for it. They told me I had to use Humalog to get the same Rx co-pay. Aren't ins. companies great (for themselves)? I used Humalog for years and it worked well. Lately, in the last two years, my blood sugars (BS) went thru the roof and I had no idea why. On a guess, I doubled my Humalog and my BS came back down. Now, using twice as much each dose, my BS are ok. Recently, I had a chance to use Novolog again. Great!!! No double dose and it starts working 20 minutes faster than Humalog. Lily will no longer be conning me with their prices. I am no longer using their ineffective and overpriced junk. Thanks Novolog. It is good to use an insulin that works."

For Diabetes, Type 1 "The insulin works but they leak and come apart inside and are HORRIBLE inaccurate because they leak and get air in them be very careful I rarely use them because of problems. A syringe is way more accurate because they don't fall apart get air in them like the other cheap ones"

For Diabetes, Type 1 "Hello, Novolog has worked for me so far. It does increase my appetite though. I got a sample from my doctor's office to begin. I then went to the pharmacy to fill my prescription and found that it costs over $500.00. I did find a discount RX card on Novonordisk´s website, but it states that you, "may pay as little as $25.00." I read the fine print and it states, "reimbursement $100 per prescription." Has anyone here ever used it? I had to find a card so I could afford my Lantus as well. I would just like to know what to expect. If it's $25.00 or only up to $100 per rx of what they cover. I'm newly diagnosed, and I would appreciate any help."

For Diabetes, Type 2 "Started on Novolog because Lantus alone didn't keep A1C low enough. it is effective and I have had to rely on it more as my insurance switched me to Basaglar which is less effective than Lantus. Being on two insulins does cause weight gain which only decreases insulin sensitivity. Sort of a losing battle to use more insulin and gain more weight. But that's what happens."

For Diabetes, Type 2 "From day 2- diarrhea Heartbeat weird Blood sugar - not much change Maybe down a little Stomach jumpy Dosage- as per blood sugar at mealtimes The pen is like shoving a serrated needle in that sticks. Not smooth or painless. My long acting pen from tresiba is very smooth in comparison. Age-69 Female Not sure of next step, due to the above mentioned sides, hopefully will discuss discontinuing with my diabetic team members, have never met the Endocrinologist…only CRNPs, PA, Nurses, Office Staff. The endo. office still charges bill for a specialist office visit. My opinion, until I am seen by the Specialist, no specialist charge."
