It Has Become Cheaper to Lose Weight

Finding out that GLP-1 drugs can help reduce weight has been life changing for many and could stem the social costs of being overweight. Recently, prices have fallen dramatically. I asked ChatGPT to for some summary data for Wegovy & Zepbound which I plot below. 

Competition matters. Initially, Wegovy was the effective monopolist selling at a list price of $1,349. In November 2023. Zepbound was approved and entered at just over $1,000 but dropped its price to ~$500 in Spring 2024. Wegovy may have sold at discount by Fall 2024, but it's direct-to-consumer price did not fall to ~$500 until Jan 2025.

It will be interesting to see if similar adjustments occur over the next few years as at least three new entrants are expected..
