As the UK and European OTC (over-the-counter) pharmaceutical markets continue to grow—projected to reach over £5 billion in the UK alone by 2025 1—brands face a paradox: more opportunity, but also more complexity. From shifting consumer expectations to digital disruption and regulatory evolution, the landscape is anything but static.

For agencies and marketers, this is a moment to step up—not just as creative partners, but as strategic navigators. Here are four of the most pressing challenges shaping the OTC space today, and how agencies can help brands not just survive, but thrive.

1. Wellness is the New Battleground

OTC brands are no longer just competing with each other—they’re up against wellness apps, beauty supplements, and functional foods. Consumers increasingly view health through a lifestyle lens, seeking products that align with their values around prevention, sustainability, and self-care.

“The consumer doesn’t want to be ‘treated’—they want to be empowered,” says a recent report from Global Market Insights 2.

Agency POV: Help brands reposition OTC products as part of a broader wellness ecosystem. This means:

  • Building emotive brand narratives that go beyond efficacy.
  • Partnering with influencers and wellness communities.
  • Designing campaigns that speak to prevention, not just symptom relief.

2.Digital-First, Trust-Last

Consumers are increasingly self-diagnosing and self-treating—over 55% of EU consumers now turn to online sources before making OTC decisions 2. But with this comes a trust gap. Misinformation is rampant, and pharma brands often struggle to cut through with credible, engaging content.

Agency POV: Agencies must help brands become trusted digital educators:

  • Create SEO-rich, medically accurate content that answers real consumer questions.
  • Use social listening to identify emerging concerns and respond in real time.
  • Develop platform-native creative for TikTok, Instagram, and YouTube that balances compliance with creativity.

3.Rx-to-OTC Switches: A Strategic Inflection Point

The trend of switching prescription drugs to OTC status is accelerating, driven by both consumer demand and regulatory shifts. In the UK, the government has actively encouraged this by reclassifying several medicines from prescription-only to pharmacy or general sales list 1.

Agency POV: Agencies can support brands through these transitions by:

  • Crafting educational campaigns that demystify the switch for consumers.
  • Ensuring regulatory-compliant messaging across all touchpoints.
  • Building integrated launch strategies that span HCPs, pharmacists, and consumers.

ECommerce is the New Pharmacy Aisle

While traditional pharmacies remain important, online sales are expected to account for over 30% of OTC revenue in the coming years 2. Consumers expect seamless, informative, and personalized digital shopping experiences.

Agency POV: Agencies can help brands win online by:

  • Optimising product content and imagery for e-retailers and DTC platforms.
  • Using data-driven personalization to improve conversion.
  • Integrating loyalty programs and digital coupons to drive repeat purchases.

Conclusion: From Creative to Crucial

The OTC space is no longer just about shelf appeal—it’s about strategic agility, consumer empathy, and digital fluency. Agencies that understand the nuances of this evolving landscape can become indispensable partners to pharma brands navigating the shift.

For pharma marketers, the message is clear: the rules have changed. And for agencies, the opportunity has never been greater to lead the way.
