Reviews for Lantus

Anonymous December 23, 2020

For Diabetes, Type 1: “I have been a Type 1 diabetic for 45 years. I have been using Lantus with Humalog for probably over a decade. At one point, I switched to Levemir, due to insurance. It worked well, even just once a day. Then, insurance switched and so did my coverage; it was back to Lantus. Most recently, my doctor wanted to try me on Tresiba, which claims to last up to 42 hours and have better blood sugar control. However, after many issues with trying to get the right dose, along with many highs and lows, I decided to go back to Lantus. I am trying to take it in the morning at 6am, rather at 9pm when I used to previously, as I would always run low in the middle of the night; it was peaking like 6 hours or so after injection. It's only been a few days, so far, so good. I'll stick to Lantus- morning or evening!”

For Diabetes, Type 2: “My sugars were out of control and I didn't know it because I had stopped checking. When I did it was 523 and my A1C was 13. My doctor was concerned and told me to start taking Lantus at a dose of 20 units per day. Then he switched it almost immediately to 30 units. After taking it a week, he upped it again to 35 units a day because my fasting sugars were still in the 180-190 range. My only side effect was that my vision became blurry - which frankly scared me! When I saw the eye doctor she told me my vision had significantly improved from one year ago!! I was very surprised and thankful to be ok. That's the only side effect I can attribute to the Lantus.”

Frequently asked questions

fullofsugar January 31, 2012

For Diabetes, Type 2: “My doctor prescribed lantus at an increase of two units every three days until my fasting sugars are at 120 or below. After two months my readings still range between 250 and 315. I started at 20 units and am now up to 50. It probably is lowering my blood sugar to some degree, but not significantly. I need something more effective. At this rate I'll be up to 80 units daily or more to reach my goal and will suffer side effects from such a high dose. I feel hungry all the time since using this and I've gained weight. ”

For Diabetes, Type 2: “People who have higher incomes on medicare and who take 2 insulins plus more than 10 other medications including additional tier 3 meds for life do not fit into any supported categories. I reached the donut hole April 19 when my monthly medicine payments were $45 for each tier 3 medicine. Now one lantus is $173 for 20 days, novalog is about the same plus a additional 250 or more for other meds. I worked hard all my life to get a decent social security and now have stopped taking my lantus because I cannot afford $173 for every 20 days. ”

For Diabetes, Type 2: “I have been a diabetic for 20 years now. I am on metformin 1000mg two times a day. I have also been on Lantus for the same time. A Doctor can tell you what to take but it may not be right. I was told to take 65 units at bedtime, but if I was sick or did not eat much that day I could bottom out in the AM. What I'm trying to say is you will have to find the right dose for you by checking your blood sugar on a regular basis.If your blood sugar was 350 at bedtime my lantus dose would be 82. I seldom take the same dose every night and I am staying in the good A1C range 22 for a 435 range will not work for me either. It's tough but you must keep a log to see what dose you gave yourself the last time and adjust it from there. Love you guy's.”

For Diabetes, Type 2: “Oral meds did not bring down the A1c nor the fasting blood sugars which stayed in the 140s and kept climbing. . I have now been on Lantus for 6 months, titrated dose every Saturday increasing dose by 4 units per week until my fasting blood sugars are averaging 100, A1c is in normal rang now. Have not had any hypoglycemia bouts which happened with the oral meds. I give this insulin a two thumbs up.”

Altaira September 26, 2010

For Diabetes, Type 1: “Lantus has been a miracle for me. Prior to using it, my blood sugars were completely out of control. My numbers were so high at times, they wouldn't even register. I did everything my doctor told me to with no success. When I was taking R and N insulin, I'd have extreme highs and lows with my blood sugars. There simply was no regulation. Lantus so far has leveled out my blood sugar levels. I take it in conjunction with Humalog. Between the two, most of the spikes I've experiences have stopped. Although with the Humalog, I do have to be careful with hypoglycemic events. The combination of the two insulins is the only thing that's ever helped me. And I've been on everything you can imagine. It looks like I'll finally control my diabetes.”

For Diabetes, Type 1: “I have diabetes Type 1 with insulin resistance. Works well. I use 200u/day, 100 AM, 100 PM. It can burn quite a bit when injected, this is because Lantus is fairly acidic with a pH of around 4. When the low pH hits the higher pH of the body, it forms microscopic crystals that are absorbed slowly. This precipitating action that causes the burn as well as makes Lantus a long-acting insulin. It helps me to inject the 100 units in 2-3 sites so less goes in per site. Also be sure to leave the needle in for 15-30 seconds to avoid leakage. I'm a chemist by trade.”

For Diabetes, Type 2: “Have been using Lantus for 3 weeks. Injecting 15-20 units per day and have not experienced a substantial reduction in glucose readings. Am upping dose to 24 units/day. Also have been taking 2.5g of Metformin with insulin shots. When my glucose goes above 300, I need to take 4mg of Glimepiride to knock it down. ”

For Diabetes, Type 2: “Lantus is my first treatment with insulin. I am presently at 22 units once a day and my numbers are much lower than before when just on metformin and glimepiride. I do not have to use glimeperide now. I do not have the terrible lows as before and my highs are a lot less. I feel better, in general but I have gained some weight.”

For Diabetes, Type 2: “Lantus does nothing for me except cause weight gain, debilitating lower back pain and spasms, sinusitis, chronic drippy nose that is beyond annoying, gastro issues, headache, heart palpitations and anxiety. It also increases my fasting glucose by a solid 4 points. If this sounds like fun to you, have at it. I've tried this insulin more than once and the side effects come faster and harder every time I play "try this" with another doctor. It's sibling, the concentrated "Toujeo" is even worse. It really concerns me the comments some people make here about insulin and diabetes in general. The lack of education about meds, diabetes and insulin is astounding. You absolutely can combine Lantus with short-acting insulin like Humalog or Novalog through the day, so ignore that review below. I also am baffled by the people who thinks they can leave Lantus out of the fridge for 2 months and not have it turn milky on them. Read the insert, people!”

For Diabetes, Type 2: “Used to inject Novolin N twice a day (50 units mornings and at bedtime) and R throughout the day. Much harder to control blood glucose and it allowed me to cheat by eating that cake and increase amounts of injections. I use Lantus now once a day. So much easier. Still trying to adjust amounts (last night blood glucose was 43). Supplement with 5 units of NovoLog before each meal. Insulin spike lasts only one hour.”

For Diabetes, Type 2: “Diabetes, Type 1 with insulin resistance. I use Lantus and rapid acting Novolog together along with diet and exercise to adjust my blood sugars and get my A1C's where I want them. I know where I feel my best, for me its 100 -120 and my doctor says they work for him too. When I was 1st diagnosed 3 years ago they said I was Type 2 but later found I really was an misdiagnosed Type 1. Not that it really makes a difference as long as its controlled, which mine is with Lantus and Novolog. Neither of which are covered by my insurance. Luckily I found a clinic that only charges $5 per box. I need 1 box plus 1 pen of Lantus and 2 boxes of Novolog per month sometimes more so I keep 4 boxes in the fridge.”

For Diabetes, Type 2: “I have been on Lantus for over 3 weeks and I feel I HAVE less control of my sugar levels. I take 22 units at bedtime, and it isnt lowering my levels like it should. Per doctor, I cannot take regular insulin with it as the Lantus is a 24 hr dose. So if my level spikes to sway 435, I can't take a shot of regular insulin to bring it down, I have to ride it out till bedtime when I can take another does of Lantus. I would rather take regular insulin every 6 hrs than do the Lantus, as It gives me more control of the dose I need for my sugar levels.”

For Diabetes, Type 2: “I have only been on Lantus , Hospital put me on it after bypass surgery and I quit p diabetes pills on my own. I was taking 30 u, then doctor increased it to 40 u. But as I am now 85 I don't watch diet like I use too, so can't blame Lantus, I also am one that can't function with fasting BS at below 100 and do better at 140. My side effects are mostly the belly fat, always hungry, Also tired more than usual, but I blame that on blood pressure pills as well. My A1C has never been below 8 in years they started the A1C check,. But here I am at 85, still have legs eye site and kidney functions, My last blood work everything met spec except AIC, Edema in feet has started to increase but that is to be expected with circulation slowing down .”

For Diabetes, Type 1: “This drug works very well. My A1C is consistently in the 5.0-5.3 range with no highs or lows. (taking Humalog as well) The other long-acting drugs just don't work as well. For example, when I was on Basaglar (for a few weeks due to insurance change) I had unexpected highs and lows. It just didn't provide the same level of regular control that Lantus does. I have a continuous monitor and keep a close eye on my levels, so I'm convinced that Lantus works much better for me.”

For Diabetes, Type 2: “I used to take Lantus while pregnant, back when Lantus came in bottles and you used syringes. I loved how I felt well on Lantus. My dr. prefers I take oral meds, so I took pills for many years. Now I must stop Actos and Invokana to stop bone density loss, so my dr. just prescribed the new pen. I am excited to feel better soon. I have too much fatigue unless I take 45 mg Actos or insulin. All pills drive down my Ha1c, but having energy is important to my quality of life.”

For Diabetes, Type 1: “I have been on Lantus about 7 weeks now, I was previously on Levemir which worked Perfect for me. I knew when it peaked and was on a very regular schedule. I switched to Lantus because of cost, my insurance supplement charges $152.57 for one vial I need 2 a month, vs Lantus will be covered at $42.00 for one vial but But IS IS HORRIBLE. I have lows almost every single night - to 36, 40, 42, 46 which is driving me crazy. I feel awful !!! I have changed dosage from original 58 units with Levemir to same with Lantus and what a nightmare. So been adjusting since down to 48-50 and STILL having lows in the middle of the night. I was told by my doctor to take it at night so that's what I do at 12:30 pm since I am a night person. But STILL have Lows. This is a NIGHTMARE. This Lantus is going to be the end of me. I have got to somehow fit the cost of Levemir back in my budget $270. a month if I get 2 vials at once. What a NIGHTMARE..”
