IV Therapy Popularity Sparks Health Concerns Amidst Lack of Scientific Evidence

The trend of "soroterapia," or intravenous (IV) therapy, promoted for wellness, longevity, and aesthetics, is facing scrutiny from medical experts. Influencer Virginia Fonseca recently shared her positive experience with the procedure on social media, reigniting a debate about its widespread commercialization. Clinics across Brazil offer these "wellness cocktails" intravenously, claiming benefits like increased energy, boosted immunity, anti-aging effects, weight loss acceleration, and improved physical performance. However, specialists warn that many of these claims lack scientific backing and can expose patients to unnecessary risks.

Endocrinologist Lizanka Marinheiro from IFF/Fiocruz explains that direct IV administration bypasses normal gastrointestinal absorption, leading to immediate circulation of substances. While this can be effective for specific medical needs, it also means that excessive doses, incompatibilities, or adverse reactions can occur more rapidly. Nutrologist Sandra Fernandes highlights the critical distinction between medically indicated IV therapy for conditions like dehydration or malabsorption and its use as a general wellness product without individual assessment or proven necessity. Experts largely agree that healthy individuals with balanced diets gain little from IV vitamin infusions, as the body efficiently absorbs nutrients orally. Reported improvements are often attributed to hydration, rest during the procedure, placebo effects, or natural symptom regression, rather than the IV infusion itself.

While IV therapy is a vital medical tool for patients with malabsorption syndromes, severe malnutrition, or specific deficiencies, its routine use for general health promotion is questioned. The procedure carries risks including infection, vein inflammation, allergic reactions, dizziness, blood pressure fluctuations, cardiac rhythm disturbances, and potential kidney or liver strain. A marketing manager, Soraia Dias, recounted a personal experience of dizziness and near-fainting after a 10-minute session, requiring emergency room observation and hydration, underscoring the potential for adverse reactions even in seemingly simple cases.
