A Toujeo Max SoloStar coupon from Rx.com is a free cash-price discount you can use at the pharmacy counter for insulin glargine U-300 (300 units/mL), the long-acting basal insulin made by Sanofi. The Max SoloStar is the higher-capacity prefilled pen: it holds 900 units, twice the 450 units in the standard Toujeo SoloStar pen. There is no generic version of this insulin, so what you pay can swing a lot from pharmacy to pharmacy. Enter your ZIP code above to see today's price at pharmacies near you, then show the coupon on your phone or a printout when you pick up your pens.
What is Toujeo Max SoloStar and how does it work?
Toujeo Max SoloStar is a prefilled insulin pen containing insulin glargine, a long-acting (basal) human insulin analog. It is FDA-approved to improve blood sugar control in adults and in children 6 years and older with diabetes mellitus, both type 1 and type 2. It is taken once daily, at the same time each day, and works quietly in the background to cover your baseline insulin needs. It is not used to treat diabetic ketoacidosis, which is treated with intravenous rapid-acting or short-acting insulin instead.
The medicine inside the Max SoloStar pen is exactly the same as the medicine in the standard Toujeo SoloStar pen. The only difference is the pen itself. The Max pen holds 900 units instead of 450, and it dials 2 to 160 units per injection in 2-unit steps; the label recommends it for people who need at least 20 units of basal insulin per day. The standard Toujeo SoloStar dials in 1-unit steps and delivers up to 80 units in one injection, which fits smaller or more finely tuned doses. One more practical note on the Max pen: each click of the dial is 2 units, not 1, so always read the dose from the dose window rather than counting clicks. Toujeo is concentrated: at 300 units/mL it is three times as concentrated as U-100 insulins, so the same number of units fits into a smaller volume of liquid.
Manufacturer savings card vs. the Rx.com cash coupon
Two very different discounts get called a "Toujeo coupon," and it helps to know which one applies to you. Sanofi runs an official savings program for Toujeo on its own manufacturer website. Programs like that are generally limited to people with commercial (employer or marketplace) insurance, and they typically exclude anyone covered by Medicare, Medicaid, TRICARE, or other government plans. Eligibility rules, expiration dates, and how much they take off all vary and change over time, so check the terms on the manufacturer's site directly before you count on it.
The Rx.com coupon is a different tool: it is a cash-price discount, not insurance and not a manufacturer program. That means it can be used by people who are uninsured, by people on Medicare or other government coverage who are shut out of the manufacturer card, and by anyone whose manufacturer card was declined or has run out. You can also use it when your plan's deductible has not been met and you are paying full price anyway. Cash prices for the same box of pens differ from one pharmacy to the next, sometimes a lot, so enter your ZIP above to compare what each nearby pharmacy is charging today. Sanofi also operates a patient assistance program for people who meet its income and coverage requirements; if paying for insulin is a hardship, ask your prescriber's office or the manufacturer about applying.
One more option worth asking your pharmacist about: Sanofi also sells this exact insulin as an unbranded "Winthrop" insulin glargine U-300. It is the same product from the same maker under a different label rather than an FDA-approved substitutable generic. It may be priced lower than the brand at some pharmacies and not at others, so compare cash prices on both before you decide.
Is there a generic? How Toujeo compares to other basal insulins
There is no FDA-approved, substitutable generic for Toujeo Max SoloStar. Insulin glargine U-300 is only sold by Sanofi, as branded Toujeo or as the unbranded Winthrop version described above. That is different from U-100 insulin glargine, where interchangeable options do exist.
If cost is the problem, these are the products worth discussing with your prescriber. Do not switch on your own, and never assume the dose carries over:
- Lantus and insulin glargine U-100, the original 100 units/mL version of the same molecule.
- Basaglar and Semglee, other U-100 insulin glargine products. Their cash prices vary by pharmacy, so compare rather than assuming one is cheaper.
- Tresiba (insulin degludec), a different ultra-long-acting basal insulin.
Switching between Toujeo (U-300) and any U-100 glargine is not a 1-for-1 unit swap. Your prescriber will adjust the dose and will want you checking your blood sugar more closely for a while afterward.
Safety, side effects, and handling your pen
Toujeo has no boxed warning. The most common and most serious risk is hypoglycemia (low blood sugar), which can be life-threatening. Your risk goes up with dose changes, skipped meals, alcohol, extra exercise, and when Toujeo is combined with sulfonylureas or other insulins. Other label risks include hypersensitivity reactions including anaphylaxis, low potassium (hypokalemia), which can also be life-threatening, fluid retention and worsening heart failure when insulin is used with thiazolidinediones (TZDs), and injection-site reactions and lipodystrophy, which is why you rotate injection sites. Toujeo should not be used during an episode of low blood sugar or by anyone allergic to insulin glargine.
Two practical safety points matter a great deal with this product. First, because Toujeo is three times more concentrated than U-100 insulin, it must never be drawn out of the pen into a syringe or put into an insulin pump, and it must not be given intravenously; dosing errors that way can be severe. Always dose straight from the pen using the pen's own dial, and do not mix or dilute Toujeo with any other insulin. Second, never share a pen with another person, even if you change the needle, because of the risk of passing along blood-borne infections. Toujeo takes about 5 days to reach steady state, so dose increases should not be made more often than every 3 to 4 days. Store unopened pens in the refrigerator; a pen you are actively using is kept at room temperature and thrown away 56 days after first use, even if insulin is left in it.
