Sostari operates as a marketplace platform that connects patients with independently licensed healthcare providers who deliver medical care through the Sostari Patient Portal. Sostari does not directly dispense medication or provide medical services; all clinical decisions are solely made by independent providers. Payment does not guarantee that a prescription will be issued or that medication will be dispensed. Any prescriptions provided are based solely on the professional judgment of the healthcare provider.‍The information on this website is for general informational purposes only and is not intended as a substitute for personalized medical advice, diagnosis, or treatment. Always consult your licensed healthcare provider regarding any medical concerns. This platform serves as an advertisement for healthcare services, not for any specific prescription medications.
