A study from Nova SBE finds 51.85% of respondents said they had self-medicated at some point, with higher rates among young people, those with more education and people without a family doctor (médico de família). Researchers warn self-medication is commonly used for mental-health issues and can be risky for people with chronic conditions if not discussed with a clinician. Those relying on regular prescriptions should ensure continuity with a registered family doctor and bring medication lists to appointments.
