How Employers Can Prepare for the Rising Impact of GLP-1 Medications

 

GLP-1s Are Already Driving Employer Pharmacy Spend

Everyone is talking about GLP-1 medications—but most conversations are missing the bigger picture.

In 2025, employers are already seeing 10–15% of total pharmacy spend tied to GLP-1 drugs.

Even more surprising? Most employer health plans aren’t broadly covering GLP-1s for weight loss.

That means GLP-1 pharmacy spend is rising before full adoption has even begun—making this less of a trend and more of a preview.

Why GLP-1 Demand Is Accelerating in Employer Health Plans

Originally developed to treat type 2 diabetes, GLP-1 medications are rapidly expanding in both clinical use and popularity.

Several factors are driving increased demand across employer health plans:

  • Expanded FDA-approved indications

  • Increased awareness and employee demand

  • The anticipated introduction of oral GLP-1 options, reducing barriers to entry

As a result, GLP-1 medications are moving closer to becoming a standard component of employer health plans.

The Risk of Waiting: GLP-1 Costs Are Rising Faster Than Expected

Many employers are still evaluating whether to address GLP-1 coverage—but waiting comes with risk.

While some manufacturers have indicated potential price reductions, those decreases are unlikely to offset the larger issue:

Utilization is expected to grow significantly.

This creates a challenging dynamic for employer health plans:

  • Higher demand

  • High cost per prescription

  • Limited existing controls

Without a proactive strategy, GLP-1 costs in employer health plans may increase quickly and unpredictably.

How Employers Are Managing GLP-1 Costs Today

Forward-thinking employers aren’t waiting for GLP-1 medications to fully hit their plans—they’re taking action now to manage future impact.

Alternative Sourcing Strategies for GLP-1 Medications

Not all access points are priced equally. Evaluating alternative sourcing strategies can help employers reduce the cost of GLP-1 medications.

Working with PBMs on GLP-1 Strategy

Employers should work closely with pharmacy benefit managers (PBMs) and carriers to understand:

  • Coverage approach

  • Clinical management strategies

  • Cost containment measures

A clearly defined PBM GLP-1 strategy is becoming essential, and you’ll need a strong Pharmacy Benefit Manager contract to match.

Planning for Long-Term GLP-1 Utilization

GLP-1 medications are not a short-term trend. Employers need a sustainable, long-term strategy that accounts for continued growth in utilization and demand.

Are GLP-1 Medications Becoming a Standard Formulary Drug?

The question is no longer whether GLP-1 medications will impact employer health plans—it’s how quickly they become part of the mainstream formulary.

As access expands and utilization increases, many plans will be forced to address:

  • Coverage decisions

  • Cost management strategies

  • Employee expectations

Employers who prepare early will have significantly more control than those reacting later.

What Employers Should Do Next to Prepare for GLP-1 Growth

To stay ahead of rising GLP-1 costs, employers should:

  • Evaluate alternative sourcing strategies

  • Pressure PBMs and carriers for a defined GLP-1 approach

  • Build a long-term plan for managing utilization

Taking action now can help reduce financial risk and create a more sustainable pharmacy benefits strategy.
