How Leucowel Injection works

Leucowel Injection helps protect healthy cells from the side effects of methotrexate, a strong medicine used in cancer and other conditions. Methotrexate can block the action of folic acid, which is essential for cell growth. Leucowel Injection works by supplying the body with a form of folic acid, allowing healthy cells to recover and continue functioning normally without affecting methotrexate's action on diseased cells.

Frequently asked questions

What is Leucowel Injection used for?

Leucowel Injection is used to prevent harmful effects of methotrexate (cancer chemotherapy medication) when methotrexate is used to treat certain types of cancer. Leucowel Injection is also used to treat people who have accidentally received an overdose of methotrexate or similar medications. It is also used for the treatment of megaloblastic anemia due to folic acid deficiency and when oral therapy is not feasible.

What is megaloblastic anemia?

Anemia is a blood disorder in which the number of red blood cells (RBCs) that carry oxygen is lower than usual. As a result, your tissues and organs don’t get enough oxygen. Megaloblastic anemia is a form of anemia characterized by very large red blood cells and a decrease in the number of those cells. Usually, megaloblastic anemia is due to vitamin B12 or folic acid deficiency. How long does it take for Leucowel Injection to work?

How long does it take for Leucowel Injection to work?

Leucowel Injection starts acting on the body within 5 minutes of administration. However, this might vary with respect to dosage, the patient receiving the drug, and response to treatment.

What are some of the laboratory tests conducted before or during the treatment with Leucowel Injection?

Your doctor will prescribe blood tests to check your levels of serum methotrexate concentration (in case of methotrexate chemotherapy or overdose) to determine the optimal dose and duration of treatment with Leucowel Injection. You will also be prescribed a complete blood count to monitor the number of red blood cells (in case of megaloblastic anemia). Along with this, your calcium levels will also be monitored in order to prevent hypercalcemia (excess calcium) since Leucowel Injection contains calcium.

What measures should be taken to ensure the prompt excretion of methotrexate during treatment with Leucowel Injection?

Maintenance of urine output above 2,500 mL/24hr in adults by increasing oral or intravenous fluids 12 hours before and for 36 hours after the end of methotrexate infusion. To monitor alkalinization of urine (this enhances drug excretion) so that the urinary pH is greater than 7.0 before methotrexate infusion. Foods, drinks, and drugs that may increase urinary acidity should be avoided during the therapy. Finally, blood methotrexate concentration should be measured at least 24, 48, and 72 hours after the initiation of the methotrexate infusion.
