Supply problems and insurance complications are making it difficult for people to access and stay on weight-loss medications like Wegovy, according to doctors and patients. Patients face challenges in finding pharmacies with the medication in stock and often have to make long drives to access it. Insurance coverage for these medications is also limited, with some Medicare and Medicaid programs not covering them and private insurers requiring pre-approval or proof of weight loss. However, experts believe that coverage may improve in the future as more employers consider covering obesity medicines.
