About Merithyl Injection Dispopack 1 ml

Merithyl Injection Dispopack 1 ml belongs to the class of vitamins primarily used to treat peripheral neuropathies and megaloblastic anaemia caused by vitamin B12 deficiency. Megaloblastic anaemia is a condition in which the red blood cells are abnormally large. Peripheral neuropathy causes damage to the nerves located outside the spinal cord and brain.

Merithyl Injection Dispopack 1 ml contains Methylcobalamin, a form of vitamin B12, which protects the nerves from damage and promotes blood cell production. It regulates body functions, such as cell multiplication, blood formation, and protein synthesis.

In some cases, Merithyl Injection Dispopack 1 ml may cause side effects such as pain, itching, swelling or redness at the injection site, nausea, vomiting, diarrhoea, and headache. Most of these side effects do not require medical attention and resolve gradually over time. However, you are advised to talk to your doctor if the side effects persist or worsen.

Let your doctor know if you are allergic to methylcobalamin, or any other medications. Inform your doctor if you are pregnant, planning a pregnancy, or are breastfeeding. Keep your doctor informed about your present and past medical history and ongoing medicines to rule out any side effects.
