Methylene Blue Capsule (Each)

Methylene Blue Capsules are a pharmaceutical preparation used for specific medical conditions such as methemoglobinemia, where the blood’s ability to carry oxygen is impaired. Additionally, it is sometimes used as a diagnostic agent or in certain research and therapeutic applications due to its unique chemical properties. The capsules are taken orally and are prescribed under strict medical supervision, as the compound affects redox reactions and blood oxygen transport.

Methylene blue works by acting as an electron carrier in the body’s enzymatic reactions. In cases like methemoglobinemia, it helps reduce methemoglobin (a form of hemoglobin that cannot bind oxygen) back to functional hemoglobin, improving oxygen transport. It also possesses antioxidant properties, helping to neutralize harmful reactive oxygen species. Furthermore, methylene blue can influence cellular energy pathways and enzyme functions, making it useful in select therapeutic settings.

This medication should not be used by individuals with known sensitivity to methylene blue or related compounds. It is contraindicated in patients with severe kidney or liver impairment, G6PD deficiency, or certain types of serotonin-related disorders. Caution is advised for those taking antidepressants, as it may increase the risk of serotonin syndrome. The capsules should only be used under medical supervision, and the patient’s overall health and underlying conditions must be carefully evaluated before starting treatment.

Common side effects include nausea, headache, dizziness, and a harmless bluish or greenish tint to urine or skin. Some people may experience gastrointestinal discomfort or mild flushing. Rare but serious side effects include allergic reactions, confusion, or difficulty breathing. In patients with serotonin-related issues, excessive use may cause agitation or rapid heart rate. Monitoring is essential to avoid complications, and any unusual symptoms should be promptly reported to a healthcare provider.

The effects of methylene blue on pregnancy and breastfeeding are not fully known, and its use is generally discouraged unless deemed absolutely necessary by a physician. Exposure during pregnancy may pose risks to fetal development, while the potential for transfer through breast milk raises concerns for newborn health. Women who are pregnant, planning pregnancy, or nursing should consult their healthcare provider before using this medication.

Store this medication at 68°F to 77°F (20°C to 25°C) and away from heat, moisture and light. Keep all medicine out of the reach of children. Throw away any unused medicine after the beyond use date. Do not flush unused medications or pour down a sink or drain.
