IQVIA prescription data is the standard read on US retail-pharmacy peptide volumes. Coverage on this site has leaned on IQVIA for launch-tracker data — the Foundayo (orforglipron) launch tracker stepped from 3,707 (Week 2) to 5,612 (Week 3) to 7,335 (Week 4) prescriptions in successive May client notes from Citi — and for ongoing GLP-1 share movements between branded and oral formulations. The May 8 Citi note also pegged Wegovy at 440,410 prescriptions in the week ending May 1 with oral semaglutide accounting for 33% of all Novo obesity referrals. Earlier in Q1, IQVIA showed Wegovy pill at 721,000 cumulative US prescriptions — about 450,000 of those on the cheapest 1.5 mg starter dose at $149/month, the central data point in the Reuters May 5 'price war test' framing.
Where IQVIA data falls short: it doesn't capture the compounded-peptide channel through 503A pharmacies and telehealth platforms, which has been a meaningful share of the post-shortage peptide economy. NovoCare's direct-to-consumer pharmacy and Lilly's LillyDirect also sit outside the standard retail pull, and Foundayo's Week 3 channel mix was 45% LillyDirect / 35% telehealth / 20% retail.

IQVIA's weekly prescription tracker for Foundayo (orforglipron) hit approximately 17,000 prescriptions for the week ending May 15, 2026, per Citi's Friday client note — Lilly's first above-15,000 weekly print since the April 6 launch. The week-by-week trajectory: 1,390 (Week 1), 3,707 (Week 2), 5,612 (Week 3), 7,335 (Week 4), 10,248 (Week 5), and ~17,000 in the new print. Novo Nordisk's Wegovy pill recorded roughly 142,000 prescriptions in the same week — the trajectory gap is narrowing as Foundayo's PBM coverage activates at the largest US plans but still remains 8.3x the Foundayo volume. Citi maintains $146M Foundayo Q2 revenue and $1.6B 2026 full-year estimates; the IQVIA print supports the trajectory. Lilly's late-May TV-advertising launch may amplify the next leg of Foundayo growth heading into mid-June.
Cumulative US Wegovy pill prescriptions, as disclosed in Novo Nordisk CEO Maziar Doustdar's May 14 commentary (>1M) and EVP Larsen's May 18 commentary on CNBC (>2M), continued to trend upward through the Memorial-Day-week lead-in. Weekly Wegovy pill volume of approximately 142,000 for the week ending May 15 — slightly above the prior week's 137,000 after the brief mid-May decline — suggests cumulative US prescriptions are now in the 2.1-2.15M range. The Wegovy pill launch (January 5, 2026) trajectory continues to outpace the comparable Wegovy injectable launch (June 2021), positioning Novo for the projected H2 2026 EU launches in UK, Germany, and Denmark. The Wegovy HD (7.2 mg injectable) CHMP positive opinion announced May 22 adds the high-dose franchise to the EU portfolio.
Fierce Pharma's Oral GLP-1 Tracker reported the first weekly decline in Wegovy pill prescriptions since the January 5, 2026 launch: scripts dropped from ~143,000 to ~137,000 in the week ending May 8. Total Wegovy (injectable + pill) scripts climbed 1.3% w/w to ~446,000, taking obesity GLP-1 market share to 40.5%. Eli Lilly's Foundayo posted Week 5 IQVIA prescriptions of 10,248, up 40% w/w from Week 4's 7,335 — the steepest weekly growth in the launch series, attributed to mid-May commercial access activation at two of the three largest US PBMs. The cumulative US Wegovy pill user count crossed 1 million per Novo CEO Doustdar's May 14 commentary; the Wegovy injectable continues to be the largest US GLP-1 single-product line. The Wegovy pill plateau and Foundayo acceleration narrow the trajectory gap that has defined the oral-GLP-1 race since April.
Even with the first weekly Wegovy pill prescription decline since launch (~143K to ~137K week-ending May 8), the total Wegovy franchise (injectable + pill) climbed 1.3% week-over-week to approximately 446,000 prescriptions per the Fierce Pharma IQVIA tracker. Market share in the US obesity GLP-1 segment ticked up 0.1 percentage points to 40.5%. The injectable Wegovy 2.4 mg and Wegovy HD 7.2 mg formulations remain Novo's commercial anchor; the pill is the growth narrative. The 1.3% w/w injectable Wegovy growth aligns with Novo's H2 2026 international expansion plans and the EU approval expected before year-end. The data also confirms Zepbound (tirzepatide for obesity) continues to grow share faster than Wegovy on an absolute volume basis — the head-to-head dynamic that Cantor Fitzgerald and Barclays both cited in their May 5 LLY price target raises.
Citi's Friday May 15 client note reported Foundayo (orforglipron) hit 10,248 US prescriptions in the week ending May 8 per IQVIA — the first 40% week-over-week jump in the launch series. Week-by-week trajectory: 1,390 (Week 1), 3,707 (Week 2), 5,612 (Week 3), 7,335 (Week 4), 10,248 (Week 5). The acceleration aligns with mid-May commercial access activation at two of the three largest US PBMs that Lilly flagged on the April 30 Q1 call. Citi maintained $146M Q2 revenue and $1.6B full-year 2026 estimates. The Wegovy pill remains ahead — Novo CEO Doustdar's May 14 commentary confirmed >1M cumulative US users since the January 5 launch — but the gap is narrowing as Foundayo's PBM coverage comes online and telehealth volume (~35% of total per Lilly executives, not captured in retail-only IQVIA data) layers on top.
Eli Lilly executives' Q1 commentary clarified the Foundayo launch-channel mix: roughly 45% via LillyDirect (the company's direct-to-patient pharmacy), 35% via telehealth platforms not captured in retail-only IQVIA data, and 20% via traditional retail pharmacy fills. The split helps explain the apparent gap between Citi's IQVIA-reported 10,248 Week 5 prescriptions and the 20,000+ patient count Lilly disclosed on the April 30 Q1 call. The pattern suggests Foundayo is being adopted preferentially through digitally-enabled care channels — Hims & Hers, LifeMD, JoinFound, and other telehealth platforms with weight-management Rx infrastructure — rather than primary-care prescribing. The mix is structurally similar to the Wegovy pill launch but with a higher telehealth share. The implication for the next 90 days: PBM coverage expansion (mid-May) and brand-name TV advertising (launching late May per the Q1 commentary) will drive most of the next leg of growth.
The next Foundayo IQVIA prescription tracker update is expected from Citi mid-week May 18-20, covering the week ending May 8. Week 4 hit 7,335 prescriptions per the May 8 Citi note with Lilly executives citing 20,000 total patients (~35% via telehealth not captured in the retail-only IQVIA data). Citi's projected $146M Q2 revenue and $1.6B full-year 2026 estimate continue to anchor the analyst consensus. Lilly executives have asked analysts for 8-12 weeks of data before reading commercial trajectory through pharmacy-fill noise; the Week 5 reading is the first post-PBM-coverage-expansion data point as the two largest US PBMs went live with Foundayo coverage mid-May. The Wegovy pill remains roughly 60-70x ahead on weekly volume (>440K in the week ending May 1 per Novo's Q1 commentary).
In its fourth commercial week (April 27–May 1), Eli Lilly's Foundayo (orforglipron) recorded 7,335 prescriptions per IQVIA, Citi told clients May 8, calling the early launch 'off to a solid start' and modeling $146M in Q2 revenue and $1.6B for full-year 2026. Citi flagged that IQVIA captures retail and partial telehealth data but likely understates Lilly Direct and the 12+ telehealth firms representing roughly 35% of launch volume; Lilly executives have cited 20,000 patients now on Foundayo. For comparison, Citi's same note pegged Wegovy pill at 440,410 prescriptions in the week ending May 1, with oral semaglutide accounting for 33% of all Novo obesity referrals.
Novo Nordisk reported Q1 2026 results May 6: net sales of DKK 96.82B (+24% YoY) and operating profit of DKK 59.62B (+54%). The Wegovy pill drove the print with DKK 2.26B (~$354M) in Q1 sales — almost double the DKK 1.16B analyst consensus — on roughly 1.3 million Q1 prescriptions and more than 2 million cumulative US prescriptions since the January 5 launch. Injectable Wegovy sales rose 12% YoY to DKK 18.2B. Ozempic sales fell 8% YoY but came in above expectations. The company tightened full-year guidance to a 4–12% sales-and-operating-profit decline at constant exchange rates, narrower than the prior 5–13% range. NVO US-listed shares rose roughly 6% on the print.
Reuters reported May 5 that Novo Nordisk's Wegovy pill posted roughly 721,000 US prescriptions in Q1 per IQVIA, beating analyst expectations on volume but raising margin questions: about 450,000 of those scripts were for the cheapest 1.5 mg starter dose at $149/month. Lilly's Foundayo approval in early April closed Novo's window as the only oral obesity pill, and Wegovy injection prices have fallen rapidly amid intensifying competition. The Danish company's market value has shed more than $400 billion from its 2024 peak. Wednesday's Q1 print (May 6, 7:30 CEST) is the test: investors are watching whether Novo holds February's guidance of a 5–13% sales and operating-profit decline at constant exchange rates, and whether direct-to-consumer NovoCare and the WW Med+ + GoodRx channels can offset price pressure.
IQVIA data cited by Deutsche Bank analysts and Pharmaphorum showed Novo Nordisk's Wegovy pill at roughly 113,354 prescriptions in its most recent reported week, up from 105,366 the week prior. That puts Novo's January-launched oral semaglutide more than 20× ahead of Lilly's Foundayo Week 3 reading of 5,612, and the gap is from US retail-channel data alone — NovoCare Pharmacy direct-to-consumer volumes are additional. Lilly executives have asked analysts to wait 8–12 weeks for a clearer read, but the early Foundayo-versus-Wegovy-pill comparison continues to favor Novo on raw volume.
Fierce Pharma's Oral GLP-1 Tracker reported May 1 that Eli Lilly's Foundayo (orforglipron) reached 5,612 prescriptions in the week ending April 24 — its third full commercial week — up roughly 51% from Week 2's 3,707 scripts but still behind the Wegovy pill's comparable third-week run. RBC and other analysts continue to caution that 8–12 weeks of data are needed to read commercial trajectory through pharmacy-fill noise. On the Q1 earnings call, Lilly USA's Ilya Yuffa said roughly 20,000 patients are now on the drug for obesity or overweight, calling the early launch 'encouraging.'
Eli Lilly shares fell April 24 after the latest weekly prescription data for Foundayo showed 3,707 scripts for the week ending April 17 — behind analyst expectations. For comparison, Novo's Wegovy pill reached 18,410 prescriptions in its second week after a January launch. RBC Capital Markets analyst Trung Huynh said early comparisons should be viewed cautiously but acknowledged the uptake is 'likely to be received negatively.' Fierce Pharma launched a weekly Oral GLP-1 Tracker to follow Foundayo and Wegovy pill head-to-head.
IQVIA tracking data reported April 21 showed Eli Lilly's newly-launched oral GLP-1 Foundayo (orforglipron) drew 1,390 prescriptions in its first full week (April 6-10), roughly 45% of the 3,071 Wegovy pill scripts in Novo Nordisk's launch week in January. Analyst consensus requires Foundayo to hit about 5.4 million prescriptions from April-December to generate $1.7 billion in 2026 revenue — a target that looks challenging at the current trajectory.
