Understanding Insulin and Its Uses
Insulin is a hormone produced by the pancreas that allows your body to use glucose from carbohydrates for energy. For people with diabetes, insulin is essential for controlling blood sugar levels. There are several types of insulin available by prescription that are engineered to provide different durations of action. These help keep blood sugar levels in the normal range between meals and overnight.
The Rise of OTC Insulin
In recent years, an over-the-counter (OTC) insulin product has become available without a prescription at some pharmacies such as Walmart. This older type of insulin differs from modern prescription insulins in a few key ways:
- It's less concentrated than prescription insulin
- It doesn't allow for precise dosing adjustments
- It acts slower and peaks later than newer insulins
While OTC insulin provides an affordable alternative for some, it has limitations to consider.
Who Might Consider Using OTC Insulin?
OTC insulin may be a reasonable option in certain situations, such as:
- You're traveling and forgot your insulin
- You can't afford prescription insulin
- You don't have prescription drug coverage
- You need insulin temporarily until you can see a doctor
However, it's important to understand that OTC insulin differs from modern prescription options. Work closely with your healthcare provider to determine if it's appropriate for your diabetes management needs.
Drawbacks and Dangers of OTC Insulin
While less expensive, OTC insulin has some significant limitations:
- It may peak at an unpredictable time. Newer prescription insulins peak at consistent times.
- It stays active in your body longer. This makes hypoglycemia more likely if not coordinated properly with meals.
- The dosing increments are less precise for matching carbohydrate intake.
- There are no options for long-acting insulin to control baseline blood sugars.
These factors make hypoglycemia, or low blood sugar, more likely with OTC insulin. Symptoms of hypoglycemia include shakiness, nervousness, sweating, irritability, confusion, rapid heartbeat, lightheadedness, hunger, and weakness.
Severe hypoglycemia can lead to unconsciousness, seizures, brain damage, or even death if left untreated. This is a key safety concern when using OTC insulin without medical guidance.
Proper Dosing with OTC Insulin
If you decide to use OTC insulin, be sure to coordinate closely with your doctor on proper dosing. Some general tips include:
- Start with lower doses than your prescription insulin and titrate up slowly
- Take doses 30-60 minutes before meals for faster-acting OTC insulin
- Adjust doses based on ongoing blood sugar monitoring and hypoglycemia symptoms
- Have fast-acting carbohydrates on hand at all times to treat potential low blood sugar
Your doctor can provide guidance on starting doses and dose adjustments to aim for optimal blood sugar control while minimizing hypoglycemia risk.
Storing OTC Insulin Properly
Like prescription insulin, OTC insulin must be stored correctly to maintain efficacy:
- Keep unopened OTC insulin in the refrigerator
- Once opened, OTC insulin can be kept at room temperature below 86°F for up to 1 month
- Do not expose OTC insulin to heat or direct sunlight
- Check expiration dates and discard expired OTC insulin
Proper storage helps ensure OTC insulin effectiveness and predictable action in your body.
Options for Affording Prescription Insulin
While OTC insulin provides an affordable alternative, modern prescription insulins offer key advantages for diabetes management. If prescription insulin costs are a barrier, some options to explore include:
Patient Assistance Programs
Most major insulin manufacturers offer patient assistance programs that provide free or very low cost insulin to qualifying applicants:
- Sanofi Patient Connection - Provides Lantus and other Sanofi insulins
- Novo Nordisk Patient Assistance Program - Provides Novolog and other Novo Nordisk insulins
- AZ&Me Prescription Savings Program - Provides Humulin and other AstraZeneca insulins
- Lilly Cares Foundation Patient Assistance Program - Provides Humalog and other Lilly insulins
These programs have certain income and insurance eligibility requirements. Talk to your diabetes care team about assistance options.
Low-Cost Human Insulins
Some retailers like Walmart offer low-cost options for certain human insulins like Novolin R, Novolin N, and Humulin R. While still prescription medications, these can cost significantly less than analog insulins.
Healthcare Clinics
Community health centers and free healthcare clinics can sometimes provide affordable prescription insulin and diabetes care services for those in need.
Prescription Discounts and Coupons
Apps like GoodRx and websites like needymeds.org provide coupons and discounts for certain prescription medications including some insulin products.
Insurance and Pharmacy Plan Options
If you have health insurance, check your plan's prescription formulary and pricing tiers. You may find options for paying less for preferred or generic insulin products. If you have a high deductible plan, an HSA account can be used tax-free for insulin costs.
Some pharmacies also offer discount generic prescription programs which may include certain insulins for a low monthly fee.
Weighing Your Insulin Options
For people with diabetes, having access to insulin is necessary for maintaining health. Work closely with your healthcare providers to find the insulin options that best fit your treatment plan, lifestyle, and budgetary needs. Be sure to use any insulin as directed, coordinate doses with meals, monitor blood sugar levels routinely, and watch closely for signs of hypoglycemia.
With some effort and advocacy, finding affordable insulin is possible. Don't hesitate to reach out to advocacy groups and your healthcare providers for help navigating the process to find prescription insulin access solutions that work for you.
