Lantus SoloStar Reviews

For Diabetes, Type 2 "When I realized I was diabetic, I was very ill. My vision went blurry, my tongue was bleeding, sores would form and not heal on my arms, so thirsty, urinating every 15 mins, etc. I have Type 2 diabetes and went on to Lantus as soon as the hospital released me. This is the best and safest way to keep your blood sugar levels normal. I have had control of my diabetes for 7 months now, and it is so easy. Had to see an endocrinologist today, and he tried to put me on Byetta, and I told him no way will you change me from my Lantus SoloStar, as it never makes me feel bad and always makes me feel good and in control. Lantus is really great."


For Diabetes, Type 2 "Lantus has been amazing for me. I struggled for so long with high blood sugar numbers, and Lantus has changed that for me. I actually have normal numbers now! Lantus SoloStar is so easy to use and completely painless! It's been incredible. Just one injection lasts all day long. Also, Lantus doesn't peak, so no low blood sugars here! I recommend Lantus and give it a ten rating. I can't stress enough how amazed I am at how well this product works! I was struggling with my blood sugar being high for so long, and nothing seemed to be working! I tried pills, other insulins, and still I was high! After taking Lantus, my blood sugar level was actually normal! It continues to stay normal now. I was so surprised at first, I even double-checked my meter!"


For Diabetes, Type 2 "It seems equal to other insulin products with the exception of the delivery system. The pen they use is junk. I'll go further, it is hazardous. The more I use it the more pens I find that jam up. Their little rubber part gets deformed and stops going down. When it stops you apply more pressure and the needle wiggles and actually tears your skin. Sometimes when you pull the pen out it will release and squirt the insulin out into the air. The problem has been ongoing across numerous pens and numerous lots. It is a design flaw or manufacturing defect."


For Diabetes, Type 2 "Insulin works fine just have trouble with pen. Always pain and pen jammed once. I use another brand of pen with no problems. Went over how to use video. I thought I was doing something wrong. But was not. Don't know why I get pain from this."


For Diabetes, Type 2 "I am new to having to use insulin, and I hate injections. While this lantus works well to control my blood sugar, twice now, the pen has lock up with 30 units of insulin remaining. Forcing me to open a new pen and inject myself a second time to complete the prescribed dosage, this along with the loss now of 60 units of medication is very annoying."


For Diabetes, Type 2 "I have been using the Lantus Solostar for about a month now. The pen is very easy for me to use. At first I had trouble just using one hand, so now after I insert the needle, I hold the pen in my left hand and depress the plunger with my right hand. This gives me more control over the entire process and with no pain."


For Diabetes, Type 2 "Lantus is great, but am going to try Levemir as their delivery system looks better. Lanus Solostar is fine for strong, large handed people, but if you have arthritis or are older, it is a chore to deliver - its too hard to push and too big to stretch your hand to insure it doesn't slip."


For Diabetes, Type 2 "I have been on Lantus for a few years now. I love it, the ease in administration of the Solostar and of the cartridge pen is wonderful. I have never had a problem with it and when using it my sugars remain in good control and I feel wonderful."


For Diabetes, Type 2 "Lantus works very well. The pen itself is awful. It jams all the time. Then you have to get a new pen and inject yourself again. That mean you have to use a new needle also. These needles and pens are very expensive. You can't use the all of this insulin that you have paid for."


For Diabetes, Type 2 "I wanted to put this out there because it may be helpful to other Lantus Solar users. I have a lot of arthritis in my hands and was having a difficult time getting the needle off after using. It helps to squeeze the plastic top but I didn’t have the strength to do this. I now hold and squeeze it with a nut cracker and then turn the vial counter clockwise. It works every time. I hope this is helpful."


For Diabetes, Type 2 "The problem is not with the medication, the problem is with the design of the pen itself. The pen often jams. This is a problem when it happens during the injection. Sometimes it won't budge and the entire pen must be thrown out. Other times it will continue delivering the insulin if you apply a lot of pressure on the purple button at the tip. This happened to me and caused the needle to scratch the tissue under my skin. Within 2 days I was in the emergency room and then spent four days in the hospital trying to get this infection under control. Surgery was considered, but finally IV antibiotics over 5 days helped and I was released to continue medicating at home. The problem I believe is with the 'gear' mechanism that they use for delivery inside the pen. Each click of the gear is a nanosecond pause and opportunity for the pen to jam. I have seen other insulin manufacturers use a 'spiral' instead of a gear which propels the insulin fluidly and safely. Try Tresiba instead."


For Diabetes, Type 2 "I have been using Lantus La SoloStar for more than 5 years with excellent results. I inject 80 units before bedtime. While the medicine certainly does its job and keeps my sugars in check, I have to agree with the fact that using the plunger mechanism is a nuisance quite frequently. I have large hands so the small hand complaint is not my issue -- it's a matter of the amount of force required to push the plunger to make it operate that's the problem. It would be appreciated if the manufacturer would take peoples complaints into consideration and redesign the plunger system. I have used other such pens in the past in an effort to help control my sugars and their plungers were nowhere near as difficult as the Lantus."


For Diabetes, Type 2 "I find it takes much more pressure to administer the insulin than it should. Also, I'm concerned that I'm not getting the proper dose because there seems to be a puddle of insulin on my skin after dosing. I've used the Tresiba pen and it was great - but my insurance won't cover anything but the Lantus pen."


For Diabetes, Type 2 "I've been using this for a month now and it seems to be helping with the blood sugars. However I find the pen hard to use. I have small hands and the pen is to wide for me to grip easily and the plunger even harder to push down to inject. I hate needles so this is ideal way for me but something slimmer and easier to push would help. At 56 iu now it's virtually impossible to avoid pain with the injection."


For Diabetes, Type 2 "I have been taking Lantus for about 10 years and like it. I have always been getting it in the vials and using the BD needles (1/2 inch). This 3-month supply came in the pens due to a screwed up order from the doctor's office. The pens are complete garbage. with "Ease of use" a ZERO. To set the dose, you rotate the end-cap to the desired amount. As my dose is 100 per day, the pen only goes to 80. Therefore I must dial up 2 50 unit doses. The needle are so thin and too short. Administering requires FORCEFULLY pressing the end cap button making the dial unwind back to 0 each time. Excessive pressure is required, while trying to hold the 1/4 inch needle in at the same time always results in bent needles and often breaking needles. Whoever designed this piece of rubbish should be forced to use it daily. If you have a choice, never use the pens and stick to the standard needles!"


For Diabetes, Type 2 "I have liked using Lantus Solostar until this last pen. I am concerned I am not getting the correct dosage as I too experience the puddling/leakage and sometimes it weeps from the site. Using same needles wonder if it is a defective pen or if it is malfunctioning."


For Diabetes, Type 2 "These pens are garbage! I use mostly products from Novo Nordisk who have the pen design to perfection. Lantus solostar pens are like some one uneducated tried to copy and failed miserably. The insulin its self works well enough, the delivery method is laughable. It needs a serious redesign, one with users in mind."


For Diabetes, Type 2 "I'm here just to say that I wish other makers of FlexPens would do as well as those who designed the Lantus SoloStar ones. I'm surprised to see the negative comments and must assume that they've since made changes! I use two others, Humalog and Ozempic, and the Lantus SoloStar is significantly better. The insulin itself works well for me."


For Diabetes, Type 2 "I was on Lantus Solostar Pens for nine months. what bugged me was dose I was taking never matched the dose lines on the pen, also there was always at least 10 - 15 units left in pen that could not come out. My co-pay was $340.00 for 5 pens. I got up to needing 70 units a day, one pen equaled 4 days. I solved that by going to vials and syringes. Still taking Lantus, it is only insulin I have been on so not sure it is best for me."


For Diabetes, Type 2 "This medicine seemed to work well for a short period of time for a friend as well as myself. Now I find that if I increase my dosage drastically or decrease my dosage drastically (over 20 units) it will help get my blood sugar where I need them, according to my doctor."


For Diabetes, Type 2 ""Insulin works fine just have trouble with pen. Always pain and pen jammed twice. Needle tip bends due to unwanted pressure need to puts on the injecting switch. " Novelog pen is easy to use. Already reported this problem to the company in July 2017 and returned the defective pen to the company. It happened again""


For Diabetes, Type 2 "I want to say my doctors had me on this for about 8 to 9 months but I hadn’t been taking it regularly with my glimepiride and metformin. So the doctor put me on a shot of Trulicity once a week, along with 22 units daily of the Lantus SoloSTAR. Along with the Metformin & the glimepiride. And although it’s my fault for the numbers to be running and the 160 to 170 range, the numbers are way better than they used to be and they’re really little to no spikes whatsoever unless I’m not exercising or I’m eating poorly"


For Diabetes, Type 2 "Been taking Lantus for just over a month has anyone else suffered from mouth and throat sores? Feels like a pill caught in your throat and cold sores inside your lip and on the side of your tongue very painful when you're trying to eat hopefully I can see the doctor that prescribed this tomorrow as I unable to eat for 3 days now"


For Diabetes, Type 2 "Lantus SoloStar Pen is easy to use - I get very few "hypos". My levels are more stable. I feel wonderful since using this. I have now been on Lantus for 12 months."


For Diabetes, Type 2 "I totally love it! The best medicine that they have ever ever come out with for diabetes type 2!"
