Sources: 4. Developments: 2. Health experts and medical professionals are warning against the dangers of self-medication, particularly when driven by social media influencers or unverified digital content. Experts note that platforms like TikTok often lack professional evaluation of an individual’s clinical history, which can lead to improper dosages, incorrect administration, or dangerous drug interactions. Specific concerns have been raised regarding the online marketing of vitamins and minerals, such as berberine, magnesium, and myo-inositol, as treatments for insulin resistance. In Brazil, Anvisa regulates these products, noting that any substance claiming to cure or prevent disease is legally classified as a medication requiring official registration. Medical professionals emphasize that self-medication can create a false impression of recovery while failing to address underlying causes. Risks include adverse reactions from prolonged analgesic use, such as kidney problems, and intoxication caused by increasing doses to accelerate effects. Experts stress that internet information and artificial intelligence cannot replace professional medical consultations. ## Timeline ### 2026-10-20: Health risks associated with self-medication Medical experts warn against the risks of self-medication, including adverse reactions, drug interactions, and delayed diagnoses caused by improper dosing or repeating old treatments. 2 sources. https://clstr.news/cluster/health-risks-associated-with-self-medication-1 ### 2026-10-13: Health experts warn against self-medication via social media Experts warn against self-medication and the use of supplements to treat conditions like insulin resistance based on social media influencer recommendations. 2 sources. https://clstr.news/cluster/health-experts-warn-against-self-medication-via-social-media --- Cite as: Health risks of self-medication in Brazil.
