The Merilog Patient Assistance Program is free to apply. Our $69.95 per month covers full advocacy. The IRA Medicare Part D insulin cap ($35/month) is a major resource for Medicare beneficiaries. Voluntary manufacturer insulin caps ($35/month) are available for many uninsured/underinsured. Biosimilar insulins offer significant cost savings vs brand.
Complete a simple eligibility form so our team can determine if you may qualify for Merilog assistance.
Our specialists gather documentation, complete applications, and coordinate with your prescriber and the assistance program.
Once approved, your Merilog is delivered through the assistance program while we manage refills and annual renewals.
Many patients try discount cards first. Here’s why the Patient Assistance Program through AffordMyPrescriptions is the better long-term solution for Merilog:
Prices fluctuate — savings aren’t guaranteed month-to-month
Copay accumulators may prevent savings from counting toward your deductible
Coupon cards expire and require constant renewal
Still $50–$150 biosimilar / $300 brand per month even with the best discount
Cannot be used with Medicare, Medicaid, or government insurance
Fixed $69.95/month — never changes regardless of retail price
Medication supplied directly through the assistance program
We manage all paperwork, refills, and annual renewals
Medicare Part D patients accepted
If denied, we explore alternative savings paths on your behalf
Eligibility is generally determined by annual household income and insurance status. Most programs follow guidelines that include limits of up to $40,000 for individuals, $60,000 for couples, and $100,000 for larger families. Because requirements vary by program and household, we encourage you to contact AffordMyPrescriptions directly so we can review your specific situation and determine if you qualify for Merilog assistance.
Merilog is the first FDA-approved insulin aspart biosimilar — a biosimilar to brand NovoLog. Same amino acid sequence, equivalent efficacy and safety, at significantly lower cost. A rapid-acting mealtime (bolus) insulin for diabetes management.
How It Works:
Diabetes management involves matching insulin dosing to physiologic insulin needs. Basal insulin (long-acting) covers overnight and between-meal glucose control; bolus insulin (rapid-acting) covers meals and hyperglycemia correction. Rapid-acting insulin analogs (aspart, lispro, glulisine) have faster onset and shorter duration than regular human insulin — better mimicking physiologic mealtime insulin. Insulin aspart (NovoLog reference product; Merilog biosimilar) has a single amino acid substitution vs human insulin — increasing the dissociation rate for rapid absorption. Onset ~15 minutes, peak ~1–3 hours, duration ~3–5 hours. Take at meal time. Merilog is a biosimilar — same amino acid sequence, equivalent efficacy and safety per FDA. Interchangeable designation allows substitution at pharmacy per state law.
Form and Use:
Merilog SC injection for meals and correction (or via pump). Vials and pens available. Dose based on carbohydrate counting and glucose levels — individualized. Diabetes education for proper insulin administration technique.
Generic Availability:
Merilog is a biosimilar to NovoLog (insulin aspart). Similar insulin biosimilars: Semglee (insulin glargine-yfgn — biosimilar to Lantus), Rezvoglar (biosimilar to Lantus), Basaglar (Lantus follow-on), Admelog (insulin lispro biosimilar to Humalog), Lyumjev (faster-acting lispro — brand). Other rapid-acting insulins: Humalog (lispro — brand), Apidra (glulisine — brand), Fiasp (faster-acting aspart — brand). Long-acting insulins: Lantus (glargine — brand and biosimilars), Toujeo (glargine U-300 — brand), Tresiba (degludec — brand), Basaglar, Semglee, Rezvoglar. Under IRA Medicare Part D insulin is capped at $35/month; voluntary manufacturer caps also exist. American Diabetes Association resources.
Warnings:
Hypoglycemia (the most common insulin adverse effect; educate patients on prevention and treatment — sugar, glucose tablets, glucagon rescue), severe hypoglycemia (unconsciousness, seizure — requires glucagon or emergency care), hypokalemia (insulin drives potassium intracellularly), hypersensitivity reactions (rare — including anaphylaxis), lipodystrophy at injection sites (rotate sites), weight gain (chronic insulin therapy), embryo-fetal considerations (insulin is generally required in diabetic pregnancy — safe with careful glucose monitoring), fluid retention with concomitant thiazolidinediones. Other: injection site reactions. Continuous glucose monitoring or frequent testing is important. Diabetes education is essential.
$50–$150 per vial or pen at pharmacies — significantly cheaper than brand NovoLog (~$300/vial). Under IRA Medicare Part D, insulin is capped at $35/month copay. Voluntary manufacturer insulin caps ($35/month) are available for many uninsured/underinsured.
Merilog is a biosimilar to NovoLog (insulin aspart) — same amino acid sequence, equivalent efficacy and safety per FDA. Merilog is designated interchangeable — it can be substituted at the pharmacy per state law without prescriber re-authorization in most states. Significant cost savings, same clinical use.
Both are insulin aspart products from the same reference. Fiasp is a faster-acting formulation of insulin aspart (contains niacinamide for faster absorption) — brand only. Merilog is a biosimilar to standard NovoLog aspart. Similar clinical use with slight timing differences.
Both are rapid-acting insulin analogs for mealtime bolus dosing, with similar onset, peak, and duration — often interchangeable in practice. Choice depends on brand/biosimilar availability, insurance coverage, and prescriber preference. Insulin lispro biosimilars (Admelog) and Humalog brand are also available.
Same as brand NovoLog: hypoglycemia (most common — educate on prevention and treatment; use continuous glucose monitor or frequent testing), hypokalemia, hypersensitivity (rare), lipodystrophy at injection sites (rotate), weight gain, injection site reactions. Diabetes education is essential.
