Health experts warn against self-medication via social media

Health experts and regulatory guidelines are warning against the risks of self-medication driven by recommendations from social media influencers. Pharmacist Paulo Arrais notes that digital content on platforms like TikTok often lacks professional evaluation of an individual's clinical history, pre-existing conditions, and specific needs, which can lead to improper dosage, incorrect administration, or dangerous drug interactions.

Specific concerns have been raised regarding the use of vitamins and minerals, such as berberine, magnesium, and myo-inositol, which are being marketed online as treatments for insulin resistance. Experts emphasize that dietary supplements are intended to complement the diet of healthy individuals and are not substitutes for medical treatment. In Brazil, Anvisa regulates these products, and any substance claiming to cure, prevent, or alleviate symptoms of a disease is legally classified as a medication and requires official registration.

Using internet information or artificial intelligence to determine medical treatments is discouraged as these tools cannot replace a professional medical consultation. Risks include adverse effects from prolonged use of analgesics, such as kidney problems, and rebound effects from frequent painkiller use.
