How a Global Pharmaceutical Company Decoded the Patient Voice Across 8+ Platforms with Merciv
AI-powered consumer intelligence revealed not just what patients were saying about their acne treatment journey — but the exact language, metaphors, and emotional frameworks they used to describe it. For the first time, four departments could hear the patient voice at scale.

The challenge
Millions of patients were talking — and nobody was listening
The company's dermatology portfolio included both over-the-counter and prescription acne treatments serving millions of patients. Those patients were actively sharing their treatment experiences — on Reddit threads, TikTok videos, Instagram comments, WebMD reviews, and half a dozen medical forums. The raw signal was there. The infrastructure to capture it was not.
The team had never been able to aggregate consumer verbatims from across these fragmented platforms into a single, analyzable dataset. Social listening tools captured volume and basic sentiment, but couldn't parse the difference between a 16-year-old describing their own treatment journey and a parent purchasing product on their child's behalf. Those are fundamentally different consumers with different decision drivers, different language, and different emotional responses — yet they were being treated as a single audience.
Even if aggregation had been possible, the team lacked a system to analyze unstructured patient language at the granularity required for meaningful insight. Traditional survey research could ask patients what they thought. It couldn't reveal how they actually spoke about their experiences in their own words, unprompted, in natural conversation. That distinction — between reported attitudes and authentic language — was the gap separating adequate marketing from resonant marketing.
The solution
AI-powered aggregation, aspect-based sentiment, and semiotic analysis
Merciv deployed its Research capability in two phases, each building on the last.
Phase 1: Large-scale verbatim aggregation and segmentation
Merciv aggregated thousands of real patient verbatims from across Reddit, Instagram, TikTok, WebMD, and multiple medical review forums — over eight platforms in total. The platform didn't just collect mentions; it categorized each verbatim into two distinct consumer segments: patient voice (individuals describing their own treatment experiences) and parent-of-patient voice (adults purchasing and evaluating treatments on behalf of their children).
This segmentation was critical. A parent describing their teenager's acne journey uses different language, has different concerns, and responds to different marketing messages than the teenager themselves. No prior research effort had separated these audiences at this scale.
Phase 2: Aspect-based sentiment analysis
With the dataset aggregated and segmented, Merciv ran aspect-based sentiment analysis across the full corpus. Rather than returning a single positive/negative score per mention, the platform extracted sentiment at the level of individual treatment attributes — efficacy, side effects, application experience, packaging, price, and speed of results. The team could now see that patients rated a product's efficacy positively but expressed frustration with texture, or that parents valued speed of visible results above all other attributes.
Phase 3: Semiotic study — the language patients actually use
The most distinctive output — and the level of research the team had never been able to access before — was a full semiotic study of patient language. This analysis went beyond what patients were saying to examine how they said it: the metaphors, emotional frameworks, and narrative structures patients used to describe their treatment journeys.
The findings were striking. Patients using over-the-counter acne treatments described their experience as a battle — language of personal agency, manageable conflict, and incremental progress. Patients on the most intensive prescription treatments used entirely different language: they described it as a nuclear war being waged on their face — language of extreme intervention, collateral damage, and high stakes.
These aren't just colorful anecdotes. They are distinct semiotic codes that dictate how each patient segment receives marketing messages, evaluates product claims, and processes treatment expectations. A campaign using “gentle daily defense” language would resonate with OTC patients but feel dismissive to prescription patients living in a “nuclear war” narrative frame.
The results
First-ever AI-powered semiotic study adopted by four departments
First-ever AI-powered semiotic study of real patient language across 8+ platforms, adopted by 4 departments.
- Thousands of patient verbatims aggregated from 8+ platforms into a single analyzable dataset
- 2 distinct consumer segments identified and separated: patient voice vs. parent-of-patient voice
- Aspect-level sentiment mapping across efficacy, side effects, application experience, price, and speed of results
- Semiotic codes identified for each treatment tier, revealing the metaphorical frameworks patients use to process their experiences
- 4 departments activated: Insights, Innovation, Research, and Marketing now use these findings to calibrate messaging, product development, and campaign targeting
The research outputs directly informed how the brand speaks to its patients — from campaign copy and media targeting to product innovation briefs and label language. The marketing team recalibrated campaign messaging to match the semiotic codes of each treatment tier. The innovation team used aspect-level sentiment data to prioritize product development. The insights team established a repeatable methodology for ongoing patient voice monitoring.
“We’d never been able to see our patients this clearly. It’s one thing to know what they think of our products. It’s another to understand the language they use to describe what they’re going through. That changed how we go to market.”

Key takeaway
The next frontier of pharma consumer research is linguistic, not just attitudinal
Traditional pharma consumer research asks patients to rate their experience on a scale. It captures attitudes. What it misses is the deeper layer — the language, metaphors, and narrative structures that reveal how patients emotionally process their treatment journeys. That linguistic layer is where marketing resonance lives.
As the FDA loosens restrictions on direct-to-consumer pharmaceutical marketing and patients increasingly turn to social media and online forums to share treatment experiences, the brands that can hear and decode the authentic patient voice — at scale — will build the deepest relationships with their consumers. The semiotic approach demonstrated here isn't a one-off study. It's a new layer of patient understanding that compounds over time.
