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

Insulin aspart "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 3 times 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 the Novolog FlexPen. I also experienced not urinating enough and 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 doorway. Ridiculous! I worked hard to lose 60 lbs."

Insulin aspart "On a 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 pain sensations feel like sewing needles. The doctor didn't know the cause and wants to test the thyroid, which was negative when hospitalized for DKA. It is always best to read the 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."

Insulin aspart "Started Novolog on Friday. Amazing blood sugar control. However, by Monday I was in the ER with chest pains and shortness of breath. The hospital said this medicine caused it. Then I looked on their site and it says it right on the side effect list. Will never take it again!!!!"

Insulin aspart "Have used Novolog for 9-10 years. It 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 the next appointment."

Insulin aspart "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 months of out of coverage for the high dollar medication."

Insulin aspart "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."

Insulin aspart "Been on Novolog for a month, also using Basaglar, 30 units a day, and Metformin ER. A1c too high at 9.1, so the doctor told me I needed to try short-acting insulin. Cost is high, one pen is $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 a big meal when carb intake is 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 than 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 a while, the injected insulin probably also becomes resistant to cell intake. So then you take more and more. Yeah, an expensive band-aid for a disease that fights back."

Insulin aspart "Been on Novolog about three years now. Take it at meals, mostly lunch and dinner. Also take Basaglar, too. Biggest complaint with Novolog is slow reaction time, which allows my carbs to raise BGL too high. If I take more, it just drops me too low later. Much more difficult to judge dosing, given that I am type 2 and my own insulin works some days better than others. I have basically accepted the spikes, as my fasting level overnight is good. Personally, I think if the Basaglar worked better, it would help balance out my numbers better."

Insulin aspart "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. I have never met the endocrinologist…only CRNPs, PAs, nurses, office staff. The endo. office still charges a bill for a specialist office visit. My opinion, until I am seen by the specialist, no specialist charge."

Insulin aspart "I have had type 2 for over 15 years. I controlled it well with diet for a while, but then moved to a long-acting insulin for better control and finally added fast-acting Novolog for meal control. I concur that the slow-acting never caused much weight gain, but the Novolog has contributed to more weight control challenges. Not completely blaming Novolog because I think my diabetes has progressed over time in causing more metabolism issues as well. My issue more with Novolog is that it really has a slower effect on reducing blood glucose than claimed. I do not find it works that quickly and in fact seems to provide little help in reducing early spikes. It does have a better effect if I significantly reduce my carb intake for dinner, but my slow-acting insulin does well controlling this without Novolog. I take Novolog to specifically handle carb intake at my bigger daily meals, but it does not seem to be that effective. The itching definitely is more so with Novolog than with Basaglar alone."

Insulin aspart "Type 2 diabetic 30 years, and have heart problems, attacks/stents (14 pills each day & Tresiba daily, Trulicity weekly & Novolog 3 times daily). Have taken Novolog a few months now, and it has not done anything as well as Humalog. I am frustrated and do not trust my doctors & pharmacy folks much anymore."

Insulin aspart "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 you're best trying to avoid using insulin as long as you can because it is sort of a grind to start using insulin."

Insulin aspart "I was forced to switch to this from Humalog when I changed insurance companies, and so far, I've had a terrible experience with this product. It says it's short term, yet I've been told to take it way before eating, unlike my previous Humalog, which was right before eating. So far, in my experience, it's more like mid-term insulin that takes far too long to begin to work, and then when it finally does, it takes six hours or more before it wears off. This has caused me numerous low blood sugar events, some of which have woken me in the night with a blood sugar read of 47. Really scary. Unfortunately, I was told by one doctor, that's what your insurance pays for, so get used to it. I understand the insurance companies want to make money and all, but they're allowed to dictate what medications I can and can't take. Answer: YES! I'm going to see my doctor in a couple of days and will be discussing this with her in the hopes of being able to go back to Humalog."

Will be speaking to my endocrinologist regarding these unwanted side effects. Have only seen the doctor one time in 6 months, otherwise, dealing with a nurse practitioner."
