For people who take insulin therapy , staying on top of multiple day-by-day injections and perplex the dose right can be an overwhelming task . Insulin penitentiary can make diabetes management easier , and they are getting easier to use and “ smarter ” by the day . Here ’s a guide to their exercise and how their design is advance .
How Insulin Injection Methods Compare
Insulin injectionsare taken by multitude with diabetes whose consistence do n’t make insulin , do n’t make enough of it , or do n’t react effectively to the insulin they are making , harmonize toMedlinePlus . They are typically ego - administered , up to several times a day , using a phonograph needle , syringe , and vial ; a playpen ; or a computerized heart , mention theCleveland Clinic . On average , hoi polloi with type 1 diabetes each injected 62 units of insulin daily in 2016 and expend $ 5,705 annually on insulin , according to theHealth Care Cost Institute ( HCCI ) .
For many people , the least - expensive way to take insulin is using a acerate leaf , syringe , and vial , because these supply are most likely to be address under Medicare , state Medicaid plan , and individual indemnity than other injection method , accord to astudy published inEuropean Endocrinology . But syringe delivery is also the most awful and difficult method , with a higher risk of dose errors and hypoglycemia ( down in the mouth blood simoleons ) sequence than other method .
citizenry who habituate pumps have insulin delivered to them 24 hours a solar day in a fashion that mime the body ’s own way of releasing insulin . Yet pump pitch can be expensive — be as much as $ 4,500 for the twist without insurance policy , an additional $ 1,500 per year in supplies , according to anarticle published inTheAmerican Journal of Managed Care .
With insulin pen , a cartridge of insulin is stop within the playpen ( it may be prefilled or need to be put in ) , the dosage is dialed on the pen , and then insulin is injected beneath the skin through a phonograph needle . To get the full dose , the pen needle should be “ primed ” with each manipulation , the boss of the penitentiary must be push all the way in and held at the injection site for 6–10 mo before the needle is pulled out . ( TheCleveland Clinic provides detailed instructionson how to inject yourself properly with a pen . )
According toGoodRx , penitentiary containing 300 social unit of insulin can cost between $ 72 and $ 254 per pen , though what you ’ll ultimately give count on the insulin you ’re using . In world-wide , playpen users tend to spend more than syringe drug user , but that can be in part because they are more likely to use high-priced parallel ( synthetic ) insulins and to shoot more units of insulin per day , notice the aforesaid study inEuropean Endocrinology .

The Benefits of Using an Insulin Pen to Manage Diabetes
“ Insulin playpen can make dispense insulin enormously well-situated for a sort of reasons , ” saysAndrew S. Bzowyckyj , PharmD , CDCES , a chemist and an associate professor at Pacific University School of Pharmacy in Hillsboro , Oregon .
“ First , there is no want for complex maneuvering to draw the insulin out of a ampule . In addition , the net venereal disease to be lot is a pot easier to see with a pen because of the relatively turgid numbers have in the dose window , rather than consider check mark marking on a syringe . Lastly , many of the new insulin formulations are now uncommitted in unequalled concentrations , which are unsafe to mete out with a traditional syringe because of the need for additional calculation to administer the correct dose . Not everyone favor to apply an insulin pen , but those who do discover it well-heeled and much more convenient to apply than the traditional vial and syringe . ” People who interpose insulin also find pens to be less painful , more convenient , and easygoing to use than syringes , according to areview in theJournal of Diabetes Science and Technology .
Yet as it digest , a slim majority of the 7.4 million people who inject insulin in the United States opt for vials and pandean pipe , harmonize to anarticle published inDiabetes Care . HCCI report that ampule made up 53 percent of insulin usage in 2016 , followed by prefilled insulin playpen at 46 percent . cartridge that go with reusable pens represent less than 1 percent of insulin used annually . Astudy published in theJournal of Clinical Medicineestimated that 350,000 people use pumps in the United States . By comparison , in Europe playpen make up about 80 percent of insulin custom , accord to areview published in theInternational Journal of Pharmaceutical Investigation .
Despite the high monetary value upfront , penitentiary injections may save people more money than syringes . Astudyof low - income Medicaid recipients with type 2 diabetes showed low overall healthcare costs for those who switched from syrinx to insulin penitentiary because overall health care avail usage was low-pitched . The survey authors hypothecate that more exact dosing ( and therefore good profligate glucose control ) may have been among the reasonableness why .
How Pens Work to Store and Administer Insulin
playpen can hold 300 to 900 units of insulin , depending on the equipment and the insulin absorption . The standard concentration is 100 units per milliliter ( mL ) of insulin , known as U-100 , though higher concentrations exist , such as U-200 , U-300 , and U-500 , according to areview published inTherapeutics and Clinical Risk Management . Typically a pen will obligate 3 mL of insulin .
The insulin is delivered through needles that range from 4 to 12.7 millimeters in distance , and thickness ( gage ) that can range from 29 ( slurred ) to 33 ( thinner ) , according to a consumer template released by the magazineDiabetes Forecast . A thicker phonograph needle is capable of giving a loony toons of insulin more rapidly , while a thinner needle is less painful to practice .
Types of Insulin Pens
They come in three discrete data format .
Disposable Insulin Pens
These come with prefilled insulin cartridge . The entire penitentiary is discarded after all the insulin has been used . Here are some good example of disposable insulin pens and their damage estimates per GoodRx :
Reusable Insulin Pens
These come with replaceable cartridges and are meant to last year .
For example , aNovoPen 4uses 3 mL Penfill cartridges of Novo Nordisk insulins , such as 300 unit of fast - acting NovoLog insulin aspart per magazine ( $ 130 per cartridge , or $ 0.47 per social unit , according to GoodRx ) . The pen can be purchased online , and the ship’s company say it is designed to last up to five age .
‘Smart’ or ‘Connected’Insulin Pens
Generally , recyclable pens are capable to record and transmit datum wirelessly and are often paired with a mobile app or a uninterrupted glucose varan ( CGM ) . Functions vary by pen , but the most integrated smart pens log glucose degree , carbohydrate intake , and the number of insulin doses administered , says Dr. Bzowyckyj .
“ Many of these insulin pen sync with an app via Bluetooth technology to help log a lot of these important elements of a mortal ’s care plan , ” says Bzowyckyj . “ Many fourth dimension , I hear patients say they may not think back if they dispense their insulin dose before a meal for a variety show of reasons , which then stresses them out because they do not need to double dose and risk hypoglycemia [ low rakehell lolly ] . Not only can insulin playpen technology assist document battery-acid administered , but it can also assist patients settle the secure STD to administer by factoring in variable star such as predict sugar intake , active insulin sentence , and current and goal glucose horizontal surface . ”
The apps may also track additional health data , such as patient weighting and steps or strong-arm action , either by syncing with a fitness tracker or when the substance abuser manually logs in the information , Bzowyckyj add up .
“ My affected role love fresh penitentiary , ” saysDiana Isaacs , PharmD , CDCES , a clinical apothecary’s shop specializer at the Cleveland Clinic Diabetes Center in Ohio who is a interpreter for theAssociation of Diabetes Care and Education Specialists . “ For any patient role of mine who takes mealtime insulin and favor not to apply an insulin ticker , this is a gravid option and one that I boost . ”
Tips for Using Insulin Pens Safely
Insulin pens that are in use can be refrigerate or kept at room temperature ( between 56 grade F and 80 degree F ) and discarded after the manufacturing business - list number of days has elapsed , harmonise toGoodRx . Often that is 28 to 30 mean solar day , but check the educational activity to be sure .
fresh pens can be proceed refrigerated ( at a temperature of 36 degree F to 46 degrees F ) and then warmed to room temperature when you are quick to use them . Once they are outside the fridge , the expiry day of the month no longer go for .
Keep in mind that cartridges and prefilled playpen only check one type of insulin . Two separate injections must be given with dissimilar insulin pens if one is using two type of insulin . And you should never apportion an insulin pen , warns theCenters for Disease Control and Prevention . Also , never use a syringe to recall insulin from a pen or magazine , which can lead to dosing errors when the playpen is used again , advises theNHS .
Recent Developments in Insulin Pen Technology
We require Bzowyckyj , Dr. Isaacs , andJoshua D. Miller , MD , the aesculapian director of diabetes guardianship for Stony Brook Medicine , about the a la mode developments in insulin pen engineering . Among the answers they divvy up were :
Here ’s a confining flavour at these ontogeny .
NewerConcentrated Insulins
“ We ’ve see tremendous improvements in using pens to drug concentrated insulin , ” says Miller , who is the medical director of diabetes attention at Stony Brook Medicine in Stony Brook , New York . “ The pharmaceutic industry has generate better at packaging those insulins in a dependable way to be able to drug the amount of insulin that the patient needs . ”
Patients who command higher doses of insulin than the traditional U-100 concentration because they have obesity or have insulin opposition only had U-500 insulin to turn to until recently . U-500 insulin also was previously only usable as a vial ; now it ’s uncommitted as a pen , further facilitating dose calculation . “ At five times the concentration of traditional insulin , it ’s very dangerous in an inappropriate amount and without accurate dosing , ” he explains .
accord to the aforementioned followup inTherapeutics and Clinical Risk Management , newer pens on the market within the last few years hold back varying concentrations of long - lasting ( basal ) insulin , such as aTresiba FlexTouchpen with 3 mL of U-200 insulin degludec ( $ 248 per playpen , or $ 0.41 per whole ) ; or aToujeo Max SoloStarpen with 3 mL of U-300 insulin glargine ( $ 315 per playpen , or $ 0.35 per building block ) — prices all agree to GoodRx . “ As a consequence of the wider handiness of some of the concentrated long - go insulin , like U-200 , affected role are able-bodied to absorb the insulin in a much more predictable way , and theirbasal insulinrequirements are satisfy more reasonably , accurately , and effectively , ” says Miller .
Administering Partial Units
The power to give half - whole venereal disease is another exciting ontogenesis , according to Bzowyckyj . Those who are especially raw to insulin ( such as children and seniors , according to areview published in theJournal of Diabetes Science and Technology ) and who utilize gloomy amounts may be more prone to dosing wrongdoing . Half - unit of measurement functionality , such as that usable in theHumalog Junior KwikPen($129 per pen , or $ 0.34 per social unit according to GoodRx ) and theNovoPen Echo , make it easy to fork out just the correct amount of insulin .
Memory Functions
“ For me , the most exciting fresh growth is the dose memory board functionality , which keeps track of the doses and time of insulin Cupid’s itch that a person self - administered recently , ” Bzowyckyj continues . “ Oftentimes , it is easy for mass to block whether or not they deal their medicament , especially with how hectic our lives can get . With traditional tablets and capsule , citizenry can just turn back their pillbox to see if today ’s space is empty , but alas , that is not an option with insulin . The dose computer memory feature article is a not bad style to forbid a somebody from double dosing their insulin . ”
Among the smart playpen with retentiveness functionality is theNovoPen Echo 5.Its half - increment dosing uses 3 mL Penfill magazine of Novo Nordisk insulin , such as 300 units of tight - acting NovoLog insulin aspart per cartridge ( $ 130 per pickup , or $ 0.47 per unit , according toGoodRx ) . The pen can cost as picayune as about $ 37 in some pharmacies but may be more expensive depending on your chemist’s , according toWellRx .
Another example is Companion Medical’sInPen , which is compatible with Humalog and Novolog U-100 3 mL insulin cartridges . Prices depart by pharmacy , but theInPen for Humalogand the Novolog version can also be around $ 37 .
Dose Calculator
Isaacs ’s patients utilize the InPen , which she prefers to the NovoPen Echo 5 . “ presently , the Novo Echo has a drug recorder but lacks the other advanced features of the InPen , ” suppose Isaacs . For instance , with the InPen , “ There is a dosing computer embedded in it , which makes calculation much wanton , ” she says . “ The calculator makes it much easier to sum the insulin needed for a given amount of sugar and a certain glucose storey . It also may take off active insulin from a previous dosage that is still working in the trunk through an sophisticated computation . ” That last function is one that Miller points out as being especially utile for debar dosing errors .
CGM Integration
Isaacs is excited about upcoming ontogeny that will give up dosing information from smart pen to be shared with continuous glucose monitors ( CGMs ) , such as a Freestyle Libre , Medtronic Guardian , and Dexcom G6 . The CGMs use a sensor telegram infix under the skin and a small , portable transmitter to send data point to a receiver or smart gadget 24 hours a day . They are typically used by people with type 1 diabetes and are particularly useful for those who are at risk for hypoglycemia and either don’trecognize the signsor experience them overnight , according to theNational Institute of Diabetes and Digestive and Kidney Diseases , though doctors are seeing more masses with type 2 diabetes who are starting to employ CGMs .
Last twelvemonth it wasannouncedthat Medtronic devices would integrate with succeeding Novo Nordisk sassy insulin pens beginning in 2020 , and the Freestyle Libre would desegregate with future insulin smart pen by Novo Nordisk and Sanofi ( maker of the Lantus Solostar insulin glargine pen ) . antecedently it was annunciate that the Dexcom G6 would desegregate with upcoming Novo Nordisk smart insulin pens .
Despite all these developments , many insulin user are n’t even aware that fresh pens exist , according to Isaacs . Miller does n’t see grow knowingness necessarily translate into wider adoption of fresh pen at all . or else , he prognosticate that over time those insulin users who are concerned in technical improvement are more likely to move over to pump therapy rather than smart pen . “ The patients I have who do n’t want to go on a pump say me that they desire to remain on a [ traditional ] pen because the pens are bare . They are easier to use and they do n’t have to believe about numbers and data . They just dial the dosage , they take it , and they are done . ”
He also sees affordability as another barrier to wider adoption . “ Outside of rebate program and coupons , ship’s company certification and the like , I have not heard of robust indemnity coverage from the manage - care and insurance companies to cover electronic pens over the cost of a traditional insulin pen . ”
In 2019,Companion Medical foretell a programto ensure that InPen user with commercial-grade insurance will pay no more than $ 99 annually for the gadget , which is project to last a year .
How to Pick an Insulin Pen With Your Doctor’s Help
So , which selection is good for you ? Isaacs suggests askingyour health care teamthe following question to determine the good fit :
Insurance coverage will likely labor your choice , says Bzowyckyj . If you have multiple choice , believe dexterity ( some pen are spring - loaded while others require the ability to stretch your thumb to administer the dose ) , whether you ’ll need to administer partial doses , and whether you prefer a disposable playpen or a reusable penitentiary that has disposable magazine , he say . “ Not everyone prefers to use an insulin pen , but those who do ascertain it easier and much more convenient to use than the traditional vial and syringe , ” he says .
