Learn how to reduce your Mar-Cof CG costs in 2026. Compare GoodRx coupons, insurance coverage, and discount options for this codeine-guaifenesin cough syrup.

Mar-Cof CG is generally an affordable medication, but the cost can vary significantly depending on whether you use insurance, a discount coupon, or pay cash at full retail price. Here's how to make sure you're paying the least possible for this prescription cough syrup in 2026.

What Does Mar-Cof CG Cost Without Insurance?

The average retail (cash) price for Mar-Cof CG is approximately $22 for a 16 fl oz (473 mL) bottle. This is the price you'd pay at most pharmacies without any coupon, discount program, or insurance. Prices can vary by pharmacy location, so it's worth comparing.

How to Use GoodRx to Save on Mar-Cof CG

GoodRx is one of the most effective tools for reducing the cost of Mar-Cof CG. According to GoodRx pricing data from July 2026, a GoodRx coupon can bring the price down to as low as $11.66 — a savings of about 47% off the average retail price of $22.04.

To use a GoodRx coupon:

  1. Go to GoodRx.com or open the GoodRx app
  2. Search for "Mar-Cof CG" or "codeine guaifenesin"
  3. Enter your zip code to compare prices at pharmacies near you
  4. Select the coupon for the cheapest pharmacy and show it at the counter

Important: GoodRx coupons typically cannot be used alongside insurance benefits. Compare both prices and choose whichever is lower.

SingleCare and Other Discount Programs

SingleCare is another popular discount program that often provides competitive pricing on generic medications including codeine/guaifenesin products. Like GoodRx, SingleCare is free to use and provides a coupon you show at the pharmacy counter.

Other discount tools worth comparing include RxSaver, Blink Health, and NeedyMeds. Prices vary between programs and between pharmacies, so it pays to compare a few options before filling.

Does Insurance Cover Mar-Cof CG?

Most commercial insurance plans cover Mar-Cof CG or its generic equivalent. As a Schedule V medication with a relatively low cost, it typically lands on Tier 1 or Tier 2 of most formularies — meaning your copay should be low, typically $0–$20.

Medicare Part D plans also generally cover codeine/guaifenesin. Check your plan's formulary to confirm coverage and see your specific tier and copay. If you have a high-deductible plan, a GoodRx coupon may actually be less expensive than using your insurance before you've met your deductible.

Does Mar-Cof CG Have a Manufacturer Savings Program?

As of 2026, Marnel Pharmaceuticals (the manufacturer of Mar-Cof CG) does not appear to offer a dedicated patient assistance program or manufacturer coupon for this product. However, given the drug's already low retail price (around $22 retail, and as low as $11 with coupons), the availability of third-party discount programs like GoodRx generally makes separate manufacturer assistance less necessary.

Save More by Asking for the Generic

The single biggest savings strategy for most patients is simply requesting the generic version: codeine phosphate/guaifenesin oral solution 7.5 mg/225 mg per 5 mL. Generic codeine/guaifenesin is therapeutically equivalent to Mar-Cof CG and is often even less expensive. With a GoodRx coupon on the generic, prices at some pharmacies can be as low as $9–$12 for a 16 oz bottle.

What to Do If You Still Can't Afford Mar-Cof CG

If cost is a major barrier, consider discussing these alternatives with your doctor:

  • Guaifenesin (Mucinex generic): OTC, available at most pharmacies for $6–$12 for 20 extended-release tablets
  • Dextromethorphan (Delsym): OTC, $8–$15 for 12-hour extended-release formula, no prescription needed
  • Benzonatate generic: Prescription required, but $10–$15 generic at most pharmacies with GoodRx

Cost Summary: Your Mar-Cof CG Savings Options at a Glance

  • Retail (no coupon/insurance): ~$22 for 16 oz bottle
  • With GoodRx coupon: As low as ~$11.66 (47% savings)
  • With insurance: Typically $0–$20 copay depending on your plan
  • Generic + GoodRx: Potentially as low as $9–$12 depending on pharmacy

Once you've identified the best price, finding a pharmacy that has it in stock is the next step. medfinder can help you quickly locate the pharmacy near you that has Mar-Cof CG available.
