2 sources · 19 Apr 2026 · Share coverage ·

Anvisa will discuss on April 29 a proposed regulation to govern the manipulation of GLP-1 medications, known as weight loss pens. The measure is part of an action plan announced on April 6 to control the market for these medications.

GLP-1 medications, known as weight-loss pens, include substances like semaglutide, tirzepatide and liraglutide and can currently only be acquired with retained medical prescriptions. The popularization of these medications has expanded the illegal market, including unauthorized compounded versions, raising concerns about health risks to the population.
