6 ways to save money on Invokana
If you’re looking for ways to save on Invokana, here are six options to consider.
1. Use a free GoodRx coupon
A free GoodRx coupon could reduce the cost of 30 tablets of 100 mg Invokana to about $593.07 at certain pharmacies. Many pharmacies accept these coupons, and you can use the GoodRx website or app to find one near you.
Here's how you can save with a GoodRx coupon:

Search for “Invokana.”
Click "Find the lowest prices" to see the best deals at pharmacies in your area.
Select your preferred pharmacy and have the coupon sent to you by text or email, or print it out.
To apply the discount, show the coupon at the pharmacy when you pick up your medication. Or show it when you drop off your prescription to prevent delays.
2. Review your health insurance plan
One of the best ways to save on brand-name medications is typically by using insurance. But in some cases, plans have high deductibles or drop certain medications off of their formulary, meaning they’re no longer covered.
If you have insurance and your plan doesn’t cover Invokana, consider requesting a formulary exception for Invokana. If the exception is denied, ask your prescriber about submitting an appeal. The exact process will depend on your insurer, but it often requires that you work with your prescriber to submit an application or letter of appeal. If you have insurance, call your prescriber’s office and ask how to get this process started.
3. See if you qualify for the Invokana copay savings card
You may be able to use a manufacturer copay saving card for Invokana to reduce your out-of-pocket costs. Through the Janssen CarePath Savings Program, your copay could be reduced to as little as $0 per month. However, the program benefits are capped at $3,000 per calendar year.
