Introduction About METHYLENE BLUE (VULC) INJECTION
METHYLENE BLUE (VULC) INJECTION contains Methylene Blue which belongs to the group of medicines called Oxidation-Reduction agents. It is used in children and adults to manage acquired methemoglobinemia.
Methemoglobinemia is a blood disorder in which there is excessive production of methaemoglobin which is a form of haemoglobin that has lost the capability to release oxygen effectively to the body tissues. It is characterized by symptoms such as headache, shortness of breath, nausea, pounding heart rate, weakness, lethargy, confusion, loss of consciousness and bluish discoloration of nail beds and skin.
METHYLENE BLUE (VULC) INJECTION is not recommended for use in patients who are allergic to methylene blue or any other thiazine dye. It is also not recommended for use in patients with G6PD (enzyme that helps in optimum functioning of red blood cells) deficiency or deficiency of nicotinamide adenine dinucleotide phosphate (NADPH) reductase.
It should be used with caution in patients with liver and moderate or severe kidney impairment. METHYLENE BLUE (VULC) INJECTION should be used with caution in pregnant women and it is not recommended to be used in breastfeeding women.
METHYLENE BLUE (VULC) INJECTION should be used with caution in newborns and infants (3 months old or younger). Also, it should be used with caution in elderly patients (aged 65 years and above) especially in patients with impaired renal function due to increased risk of side effects.
