Learning about the Solostar Pen

Hi, meldoy! I so wisdh I had seen your question 15 months ago, and I do hope you did get this answer in that time, but if not, here goes!

What your vials and pens say is that the CONCENTRATION of the insulin is 100 UNITS PER 1 CC (which is the same as a mL, milliliter) The VOLUME contained in the vial is 10cc, which is 1000 UNITS, and the pens all contain 3cc which is 300 UNITS. You can see that a vial has a bit more than the contents of 3 pens in it.  ALL insulin sold in the US is 100 UNITS per cc, and all is the human insulin analog produced by recombinant DNA technology. We can thank the brilliant researchers--and the volunteers in the clinical trials--at UCSF for this advance. Not all GMO's are monsters!

I doubt that any pharmacy could even obtain animal-source insulin anymore, or legally provide it to you. When I was a kid, animal-source insulin was available in U-40 (40 UNITS per cc) and U-80 (80 UNITS per cc) and on special order to Lilly  U-500 (500 UNITS per cc), used for people who were extrememly resistant, or for pregnant women whose insulin requirements had skyrocketed ( I was taking 180 units at a time, 3 times a day!)

I do like the pens because it is so easy to just dial the dose, and to carry them arounds

Hi, folks! I have just noticed this forum: sorry it took me so long! A comment about the Solostar pen: yours is the only positive comment I have heard about it! I have used just abour every device and pen there is (except the MediJector, which might not be on the market anymore) in the 46 years I have been on insulin, and found the Solostar to be a real pain in the !@#$%&*! I did use Lantus for about 7 years, until my body apparently stoppped absorbing it, and then switched to Levemir in FlexPens (which are much easier to schlep around). I had to start using a pump (something I was actually trying to avoid, because of the expense and inconvenience) because NO long-acting insulin was providing the activity my body needs. I am getting a much better response, and using less insulin total, by using only the short-acting insulin --most similar to what our bodies actually produce when the beta cells are working-- in the continuous infusion pump. That's MY exsperience: is there anyone else who has been an insulin junkie for a L-O-N-G time who has noticed this happen? Also, I'd really like to know whether ANYONE has done any research or data collection on how menopause affects Type 1 diabetes! When I was a kid, diabetic girls weren't expected to live to become menopausal grandmas, but here I am!  My suggestion for seniors who are  worried about Medicare coverage: find the best Medicare Advantage plan--which is probably an HMO, if there is one in your home area--and speak to a medical social worker to make sure you are qualified for a Chronic Conditions Management plan or similar that emphasizes preventive care. The lack of access to medical care is shameful! I know: I could not get health insurance--even  the group plan from my employer--because of my "pre-existing condition" and had to get so sick I couldn't work anymore. THEN I could get public insurance, but only after I had exhausted whatever savings and resources I had (including having to sell my car).  Those who decry "Obamacare" should have to live with insulin-dependent diabetes!

HI Mike and everyone.

I did try the solostar pen. Loved it. I kept it cool (in my hot kitchen) by putting it in a little container and put a cold keeper in it. Not on it, but nearby and it brought the temp in the kitchen down to a normal degree so I could leave this on my kitchen table. What a nifty thing. Did it until there was no more and went to a new pen. I still had a vial of the Lantus in my fridge so I'm on that now. My doctor gave me some samples of the Levimir pen. I read where that pen lasts for 42 days (how come that's 42 days and Lantus is 28 days). Doesn't matter because at 16 units it's just like Lantus. That's what my doctor told me. He said 'it's a newer version and does what Lantus does".  I said fine.

I watch my blood sugar very carefully and I'd like to share with you what I have discovered. I had been eating a perfect diet (no cheating) and had good results. But a friend gave me a Vitamix and every night I make banana chocolate ice cream (using frozen bananas, some cocoa powder, some ice and some Fifty50 sweetner and a dash of skim milk. Well, you have never tasted anything so delicious in my life. and my blood sugar readings went down. Must be the bananas or the cocoa powder or whatever but everything improved once I started making stuff in the Vitamix. I make soup, I make ice cream. I make wheat grass smoothies. I'm not too big on frut so for me, it's just a banana every night and yesterday my fasting bc was 79.  Can you believe this. My post prandials are about 126.  So whatever I'm doing must be working. I do not eat anything out of a package. I sprout my foods, I use REAL food and now I Vitamix. What a god send.  

Anyone else here have a Vitamix?

I know it has been quite a while since anyone has posted on this subject, but thought I would add my information anyway.

The website for Lantus information says that you can keep the opened Lantus at room temp or in the refrigerator. I find that it burns less or not at all, when I keep it in the refrigerator and use it right from there. I do it all the time.

It also helps me to not make a mistake and pick up my Novlog pen and take it for the Lantus (which I did once!).

Hi there.  Thanks for all the information.  I'm not going to be using this pen until September 1st. It's too hot to keep a pen on my kitchen table. I have insulin (vials) to use until then.


And thanks for the heads up about taking it out two hours before using it for the first time. Didn't know that. You saved me from burning.

Hello Melody,


Well, this is my first post...Don't know if I can help or not as I just started takeing insulin and started out useing Lantus SoloStar.

I was told to keep un-opened pens in the refrigerator till two (2) hours before useing....(trust me on that as it burns BIG TIME if you don't) you can then use it up in 28days.... The pen has 300 units of U-100 insulin (3 cc) I use 35units per shot and some days wind up takeing two shots as 35 doesn't go into 300 very even..So every 8 1/2 days I use one pen and open a new pen to finnish my dose...... You with your 16units will use up the one pen in 18 days and on the 19th day use the left over 12 units plus add 4 more units from a new pen....(don't forget to take it out two hours before useing)

I will say that I'm on my second month of insulin so don't take my word but do listen to your DR. and if you don't understand before you leave his/her office ask again....I'm 63 and I use a tape recorder just in case I don't hear him correctly....

Also, my bride of 29 years made me a "Pen Quilt" to keep my open pen in while inside my "Man Bag" also when on the road it keeps my un-opened pens cool.  I haven't taken a trip on the airlines yet so will need to find out just what that will entail keeping the un-opened pens at the right temp...

Hope this helps...Take care and stay safe...

Hi All

I've been using Lantus for 7 years with no problems. I use the vial and the syringe. I take 16 units before bedtime and this works fine. Because my friend uses Lantus, and she uses the Solostar Pen, she gave me one and she wanted me to learn how to use it. I want to wait until the heat wave is over in NY because I have read that once you take it out of the fridge, you can keep it out (if the room temperature is normal). Right now, it's over 90 in my apartment so it's not normal, right?

So right now, as I have been doing for 7 years, I am still using the vial and the syringe.

So here's my confusing question.  Both the vial and the pen say it has 100 units.  I've been starting a new vial on the 1st of the month. With no problems. Even though some months have 31 days, I've been doing this.

If I have been using 16 units every day and you times that by 28 days, that's a lot of units. So How can one vial or the pen, have 100 units?

I remember once asking my doctor (when, in the beginning I was taking a lot more insulin), I remember saying "one of these little vials has 100 units??" and he explained it to me but I forgot what he said.  I know that one vial is good for one month and it has enough insulin for my needs.

I'll probably start the solostar pen around September. It will be cooler in my apartment by that time. So once I dial the pen to 16 and I take the shot, then every night before I go to bed I just put a new needle tip on it, dial it to 16 and that's it, right?  Will one Solostar pen last for one month. I tried to do the math in my head but 16 times 28 adds up to much more than 100 units. 

See my confusion?

If someone can please clear this up for me, I'd appreciate it.

Thanks much
