Consumers may face increased scrutiny of supplement purchases and potential restrictions on over-the-counter products during cancer treatment. Could increase healthcare costs through mandatory consultations and reduce out-of-pocket supplement spending. May improve treatment outcomes and reduce adverse events, benefiting patient outcomes long-term.
Potential regulatory tightening on supplement labeling and drug interaction warnings. May drive stricter pharmaceutical interaction databases and healthcare provider protocols. Could lead to enhanced patient education requirements and standardized disclosure forms in oncology practices. Possible increased oversight of supplement marketing claims.
