Dihexa requires particularly careful clinician oversight because robust human safety studies are lacking. Its activity around HGF/c-Met growth-factor signaling is biologically significant, and the long-term implications of manipulating that pathway in healthy people are not well defined. Your clinician will review cancer history, neurologic conditions, medications, pregnancy status, and the reason for seeking treatment before considering Dihexa. Patients should report new headaches, neurologic symptoms, mood or sleep changes, gastrointestinal symptoms, or other unexpected effects.
