Is Methylene Blue Safe? an In-Depth Look at Daily Use Risks, Side Effects, Long-Term Safety, and Who Should Avoid It
Reading Time: 27 minutes. Methylene blue has a well-established safety profile at therapeutic doses of 0.5-2 mg/kg, with FDA approval for the treatment of methemoglobinemia since 2016. Safety depends critically on dosage thresholds, as toxicity emerges above 7 mg/kg, causing hemolytic crisis and cardiovascular complications. Individuals with G6PD deficiency face heightened hemolytic risks even at…

Does Methylene Blue Affect Blood Pressure Levels?
Reading Time: 13 minutes. Methylene blue exhibits significant effects on blood pressure through multiple mechanisms. The drug primarily acts by inhibiting guanylate cyclase, reducing cGMP levels and nitric oxide release, leading to Vasoconstriction and increased vascular tone. Administration typically induces a rapid elevation in mean arterial pressure within 30-60 seconds, with effects normalising in 90…

Methylene Blue and Mental Health: From Anxiety and Depression to Neurodegeneration and Recovery Research
Reading Time: 22 minutes. Methylene blue exhibits psychiatric potential through the inhibition of monoamine oxidase A at nanomolar concentrations and the enhancement of mitochondrial complex activity. Randomised controlled trials establish efficacy for residual depressive symptoms in bipolar disorder, with ideal dosing at 15 mg daily producing significant improvements in depression and anxiety measures without manic…

Exploring Fungal Links to Brain Health and Innovative Treatments
Reading Time: 7 minutes. Recent research demonstrates compelling links between fungal exposure and neurodegenerative conditions, with myconazole emerging as a promising dual-function treatment. Studies show that this antifungal compound reduces hippocampal neuroinflammation and improves memory retention in mouse models. The connection involves complex interactions between mitochondrial function, cytokine responses, and neural health. With brain disorders affecting…

Methylene Blue and Huntington’s Disease: What Research Reveals
Reading Time: 9 minutes. Research shows that methylene blue disrupts huntingtin protein aggregates that cause Huntington’s disease by interfering with hydrogen-bonding networks and β-sheet formation. Studies demonstrate it effectively blocks aggregate formation in cell cultures, extends lifespan in Drosophila models, and delays symptom onset in R6/2 mice when treatment begins early. The compound also enhances…

Is Long-Term Methylene Blue Use Safe? Contraindications, Daily Dosing Risks, and What Research Really Shows
Reading Time: 21 minutes. Long-term methylene blue use appears safe at therapeutic doses of 0.5-2 mg/kg body weight, with typical protocols using 10-30 mg daily for neurological benefits. Research indicates doses exceeding 5 mg/kg approach toxic territory, causing cardiovascular, gastrointestinal, and haematological complications. The compound exhibits a narrow therapeutic window, where low doses enhance mitochondrial…

How to Use Methylene Blue Safely: Dosage by Weight, Risk Factors, and the Blu Brain Calculator
Reading Time: 16 minutes. Methylene blue is a redox-active antidote for methemoglobinemia dosed by weight. Typical dosing is 1 mg/kg IV over 5–30 minutes, diluted in 5% dextrose; avoid sodium chloride. Do not exceed 5 mg/kg/day or 7 mg/kg cumulative (stricter: ≤4 mg/kg for aniline/dapsone). In paediatrics, standard doses are 0.3–1 mg/kg with a single…

Methylene Blue for Anxiety and Mood Disorders: Evidence and Limitations
Reading Time: 11 minutes. Methylene blue shows promise for anxiety through its mitochondrial-enhancing effects, particularly improving fear extinction in claustrophobia trials at 260 mg doses. You’ll find evidence suggesting enhanced memory consolidation and ATP production in neural circuits, though research remains limited by inconsistent dosing protocols and variable patient responses. It’s contraindicated if you’re taking…
