Prescription fills for weight loss drugs more than doubled in 2024 despite limited insurance coverage and high costs, according to GoodRx. Zepbound prescriptions surged over 300 in its first year, while Wegovy fills grew by more than 100. Less than 14 of commercial insurance plans offer unrestricted coverage for these drugs. Patients often face out-of-pocket costs exceeding $2,500 annually, even with insurance. Medicare currently excludes weight loss drugs unless prescribed for other conditions. A Biden-proposed rule could expand access and increase costs, pending Trump's approval.
