When you’re managing ongoing health conditions like diabetes, high blood pressure, or high cholesterol, those monthly pharmacy runs can add up in both time and money. Here’s a simple change that could cut your prescription costs and reduce those trips by two-thirds: switching to 90-day supplies.

This isn’t just about convenience (though never running out of your medication on a busy Tuesday is pretty wonderful). It’s about real savings that can make a meaningful difference in your monthly budget, especially when you’re taking multiple medications.

How 90-Day Prescriptions Save You Money

The math is straightforward: instead of paying three separate copays throughout the year for the same medication, you typically pay just two copays for a 90-day supply. With many insurance plans, you get a 90-day supply delivered to your door for the cost of a 60-day supply, often less.

Here’s What the Savings Look Like:

• If your monthly copay is $20, you’d normally pay $240 per year for that medication

• With a 90-day supply, you might pay $35 for three months’ worth. That’s $140 per year

• Annual savings: $100 per medication

Multiply that across several medications, and you’re looking at hundreds of dollars in savings each year.

Two Ways to Get Your 90-Day Supply

You’ve got options for how to receive your longer prescription supplies, and both offer significant benefits.

Mail-Order Pharmacy

Most insurance plans offer mail-order pharmacy services through providers like Express Scripts or your plan’s designated mail pharmacy. Here’s what to expect:

• Delivery timeline: Usually 7-10 business days for your first order, then you can set up automatic refills

• Cost advantage: Often the lowest copay option available through your plan

• Convenience: Medications arrive at your door with no delivery fees

• Best for: Maintenance medications you take regularly

Retail 90-Day Programs

Major pharmacy chains now offer 90-day supplies in-store, often called “Retail-90” programs:

• Walgreens 90-day refills: Available at all locations with potential copay savings

• CVS Pharmacy: Offers 90-day supplies at retail locations, especially for plan members

• Local pharmacies: Many independent pharmacies also participate in retail 90-day programs

The retail option gives you face-to-face interaction with pharmacists and immediate pickup while still offering most of the cost benefits.

Medicare Members Get Extra Benefits in 2025

If you have Medicare Part D coverage, 2025 brings significant improvements. The biggest change in 2025 is a new $2,000 cap on annual out-of-pocket prescription drug expenses, which will help an estimated 3.2 million people in Medicare prescription drug plans save money on their covered medications this year.

Additionally, people with Medicare Part D can choose to spread out their out-of-pocket prescription drug costs throughout the calendar year, allowing for more predictable, lower monthly costs instead of paying all at once at the pharmacy.

Which Medications Work Best for 90-Day Supplies

Not all prescriptions are good candidates for extended supplies. The 90-day strategy works best for:

Ideal Candidates:

• Blood pressure medications

• Diabetes medications and supplies

• Cholesterol medications (statins)

• Thyroid medications

• Antidepressants

• Heart medications

• Arthritis medications

Not Suitable For:

• Antibiotics or other short-term treatments

• Pain medications (controlled substances often have restrictions)

• Medications you’re just starting (in case you need dosage adjustments)

• Medications that expire quickly

Getting Started: Simple Steps

Making the switch is easier than you might think:

For Mail-Order:

1. Contact your insurance plan to confirm mail-order benefits
2. Ask your doctor to write a new prescription for a 90-day supply with refills
3. Have your doctor send the prescription directly to your plan’s mail-order pharmacy
4. Set up automatic refills to ensure you never run out

For Retail 90-Day:

1. Ask your pharmacist if your plan covers 90-day supplies at their location
2. Request your doctor write a 90-day prescription
3. Transfer your prescription to a participating retail pharmacy if needed

Smart Tips for Success

Start with one medication: If you take multiple prescriptions, try the 90-day approach with one medication first to see how it works for your routine.

Time it right: Order refills when you have about a two-week supply remaining to avoid running out.

Keep a backup plan: Know which nearby pharmacies can fill your prescriptions in case of delivery delays or emergencies.

Track your savings: Keep receipts to see how much you’re actually saving. It can be quite motivating!

The Bottom Line

A study from the American Journal of Managed Care shows an automated 90-day supply of a maintenance drug leads to higher adherence and less waste than 30-day supplies. You’re not just saving money. You’re setting yourself up for better health outcomes by making it easier to stay consistent with your medications.

Whether you choose mail-order delivery or retail pickup, switching to 90-day supplies for your maintenance medications is one of the simplest ways to reduce both your pharmacy costs and the mental load of constantly refilling prescriptions. Your wallet and your health will thank you for it.
