How Vulcan Injection works
Methylene blue acts as a reducing agent to reduce methemoglobin to hemoglobin. It is reduced to leucomethylene blue in the red blood cells of our body, by combining with a chemical nicotinamide adenine dinucleotide phosphate (NADPH), in the presence of an enzyme called NADPH reductase. Leucomethylene blue reduces methemoglobin to hemoglobin and restores the oxygen carrying capacity of hemoglobin. This helps in the treatment of Methemoglobinemia.

FAQs
What is Vulcan 10mg Injection used for?
Vulcan 10mg Injection is used to treat acquired methemoglobinemia (when blood cannot carry oxygen well), helping restore normal oxygen levels in the body in adults and children.
Who should not receive Vulcan 10mg Injection?
People with G6PD deficiency (a red blood cell enzyme problem) must not receive Vulcan 10mg Injection because it can cause severe hemolytic anemia (breakdown of red blood cells). Also, anyone with a severe allergy to methylene blue or similar dyes should not receive it.
Why is there a serious warning with Vulcan 10mg Injection and antidepressants or some pain medicines?
Vulcan 10mg Injection can dangerously raise serotonin (a brain chemical) when used with serotonergic drugs such as SSRIs/SNRIs (many antidepressants), MAOIs, linezolid, some opioids, or dextromethorphan (cough medicine). This can lead to serotonin syndrome (agitation, fever, fast heartbeat, stiff muscles), which is life‑threatening.
What are emergency warning signs after receiving Vulcan 10mg Injection?
After receiving Vulcan 10mg Injection, get help right away if you develop a severe allergic reaction (swelling, trouble breathing, hives), signs of serotonin syndrome (confusion, high fever, shaking, stiff muscles, diarrhea), chest pain, seizures, or signs of anemia (extreme tiredness, pale skin, yellow eyes/skin, dark urine).
Can Vulcan 10mg Injection affect oxygen monitors?
Yes. Vulcan 10mg Injection can make pulse oximeters (finger oxygen clips) read low by mistake. Doctors may use blood tests instead to check oxygen levels after the injection.
I have kidney or liver problems. Does that change anything about Vulcan 10mg Injection?
Kidney or liver problems can make Vulcan 10mg Injection stay longer in your body, so doctors may use fewer doses and monitor you longer for side effects.
What if the first dose of Vulcan 10mg Injection does not fix the problem?
If methemoglobinemia does not improve after two doses of Vulcan 10mg Injection, doctors will consider other treatments instead of giving more methylene blue.
Can Vulcan 10mg Injection change lab tests or cause staining?
