Don’t let the high cost of brand short-acting insulin disrupt your treatment. We help eligible patients access Humulin R (Regular human insulin) for as little as $69.95 per month through the manufacturer’s Patient Assistance Program.
The Humulin R Prescription Assistance Program is a manufacturer-sponsored initiative that provides Humulin R at little or no medication cost to qualifying patients based on income and insurance status. The program is designed for diabetes patients who are uninsured or underinsured.
Navigating the program on your own means dealing with eligibility verification, prescriber coordination, prior-authorization documentation (where insurance requires it), and renewal deadlines.
AffordMyPrescriptions eliminates that burden. For a flat $69.95 per month, our Patient Advocates handle every step of your enrollment, from initial application through ongoing refill coordination and annual re-certification — so you focus on your diabetes management, not paperwork.

The Patient Assistance Program is free to apply for and provides Humulin R at little or no medication cost if approved. But the process involves detailed applications, prescriber coordination, and ongoing renewal management. Our $69.95/month service covers full advocacy. Note: Humulin R can be purchased OTC at most pharmacies, and Walmart’s ReliOn brand of regular human insulin is significantly cheaper at ~$25/vial — for many patients, ReliOn or the federal $35/month Medicare cap is the better path.

Humulin R (Regular human insulin) is a short-acting mealtime insulin used to improve glycemic control in adults and pediatric patients with type 1 or type 2 diabetes. It is also used for treating diabetic ketoacidosis (DKA) and hyperkalemia in hospital settings, and is the basis for the more concentrated Humulin R U-500 (500 units/mL) used for patients with severe insulin resistance.
How Humulin R Works:
Humulin R is regular human insulin created through recombinant DNA technology to match the insulin naturally produced by the pancreas. It typically begins working within 30 minutes, reaches its peak effect at 2–4 hours, and lasts for about 6–8 hours. While newer analogs act faster, Humulin R remains a staple in diabetes care due to its long track record, affordability, and over-the-counter availability in most states.
Form and use:
This medication is administered via subcutaneous injection and is available in standard 100 units/mL vials and KwikPens, as well as a concentrated U-500 version for severe insulin resistance. To ensure the insulin begins working when food is digested, it should generally be taken 30 minutes before a meal. Dosage is always individualized based on a patient’s specific metabolic needs and blood-glucose monitoring results.
Generic availability:
While there is no “generic” in the traditional sense, lower-cost human insulins are widely accessible, such as Walmart’s ReliOn brand which is significantly cheaper. The manufacturer also provides an authorized lower-cost version of the medication. Patients may also consider rapid-acting analogs like Humalog or Novolog, though these options are typically more expensive and offer a faster onset of action.
Warnings:
The most significant risk is hypoglycemia, which can be severe or life-threatening if blood sugar levels drop too low. Other side effects include weight gain, fluid retention, and low potassium levels. Specialized care is required for the concentrated U-500 version to avoid dosing errors, and patients should always rotate their injection sites to prevent the development of lipodystrophy.
Humulin R can be purchased over-the-counter for approximately $150–$200 per vial. Walmart’s ReliOn Regular brand is significantly cheaper at ~$25/vial. Through AffordMyPrescriptions, qualifying uninsured patients receive Humulin R at no medication cost — our $69.95 monthly fee covers full advocacy and program management.
Yes. Humulin R (and Humulin N) is available over-the-counter at most pharmacies in most U.S. states, although a prescription is recommended for proper dosing guidance. Note that this OTC availability does NOT extend to insulin analogs (lispro/Humalog, aspart/Novolog, etc.), which require a prescription.
Humulin R is short-acting Regular human insulin used as mealtime coverage (peaks at 2–4 hours, lasts 6–8 hours). Humulin N is intermediate-acting NPH human insulin used as basal coverage (lasts 12–18 hours). Both are human insulins (not analogs) and are available OTC, but they serve different roles in a diabetes regimen.
Humulin R U-500 is a 5x concentrated version of regular human insulin (500 units/mL instead of 100 units/mL). It’s used for patients with severe insulin resistance who require more than 200 units per day. U-500 has a longer duration of action than U-100 (peak at 4–8 hours, duration up to 24 hours) and is used by prescription only — it requires extra care because of dosing-error risk if confused with U-100.
Yes. Walmart’s ReliOn Regular (~$25/vial) is the same regular human insulin at a fraction of the brand price. The federal $35/month Medicare Part D insulin cap and many state laws cap commercial insurance copays at $35/month. The manufacturer also offers an authorized lower-cost version. We mention this directly because for many patients, ReliOn or the $35/month cap is the better path.
Unopened Humulin R vials and pens should be stored in the refrigerator until the expiration date. Once in use, vials and pens can be kept at room temperature (below 86°F/30°C) for up to 31 days. Do not freeze, and do not expose to direct sunlight or heat. Humulin R is a clear solution and does not need to be resuspended (unlike NPH-containing insulins).
If your initial application is denied, we explore alternative savings paths on your behalf — including switching to Walmart ReliOn Regular (~$25/vial), the manufacturer’s authorized lower-cost version, the federal/state insulin price caps, or asking your prescriber whether a rapid-acting insulin analog (with its own assistance program) would be a better fit. If we cannot find a path, you will not be charged our service fee.
If you are struggling with the high cost of Humulin R, our team may be able to help you access assistance programs designed to make brand short-acting human insulin affordable — or guide you to the much cheaper ReliOn or authorized lower-cost paths if they fit your situation.
