Lilly’s Foundayo is reportedly off to a strong start.
The company’s obesity only recently hit the market, and a report from Reuters says that the pill saw 1,390 prescriptions in its first week.1 The data, collected and analyzed by IQVIA, is reportedly based on two days of capture, ending on April 10.

However, rival weight-loss drug provider Novo Nordisk’s Wegovy launched in January of this year and reportedly saw 3,071 prescriptions during its first four days. Both companies are fighting for control of the obesity medication market space.
How are analysts reacting to Foundayo’s launch?
RBC Capital Markets analyst Trung Huynh spoke with Reuters on the two launches and explained that comparing early launch data won’t provide the full picture of which drug is more popular. Instead, he says its important to see how Foundayo compares to the Wegovy pill at about eight-to-ten weeks.
Reuters also reports that shares for Eli Lilly rose 1.6% before the markets opened on Friday, April 17th (the same day this news broke).
Analysts are closely watching the market, as oral versions of the medications are entering alongside the traditional injectables. So far, injectable versions of weight loss medications still lead sales.
Earlier this week, FDA announced that despite Foundayo’s approval, the agency still required post-approval safety studies for the medication. The agency’s approval letter detailed a series of risks that it believed it could not fully characterize based on existing data. These risks include:
- Heart attack
- Strong
- Drug-induced liver injury
- Delayed stomach emptying
FDA also requested 15 years of thyroid cancer risk data, which is consistent with the existing warnings on previous iterations of Wegovy and Zepbound. However, the agency also requires Lilly to establish a registry of children and pregnant women taking the medication to treat obesity to monitor outcomes.
