Rofolin® is the active form of folic acid. It acts as an antidote in poisoning caused by various agents, including methanol and methotrexate, and is also used as a biochemical modulator to enhance the efficacy of certain chemotherapeutic agents.

  • Toxicity due to folic acid antagonists (e.g., methotrexate and pyrimethamine)
  • Enhancement of the therapeutic effect of 5-fluorouracil in cancer treatment
  • Megaloblastic anemia due to folate deficiency
  • Adjunct treatment in methanol poisoning
  • Various malignancies, including cancers of the bladder, biliary tract, esophagus, stomach, pancreas, colon, rectum, and leukemia
  • Prevention of graft-versus-host disease (GVHD)
  • Tubal ectopic pregnancy
  • Gestational trophoblastic neoplasia

Lyophilized powder containing 100 mg and 200 mg calcium folinate for preparation of an injectable solution

To prepare the solution, add 10 mL of sterile water for injection to the vial containing the lyophilized powder and gently swirl until complete dissolution. The resulting solution is clear to slightly yellow and contains 10 mg folinic acid per mL.

For intravenous infusion, Rofolin® may be diluted with the following solutions:

  • Hypersensitivity to calcium folinate or any of the excipients
  • Pernicious anemia and other anemias caused by vitamin B12 deficiency
  • Intrathecal administration is contraindicated

If signs of hypersensitivity reactions occur—such as redness, swelling, skin rash, blisters, urticaria, pruritus, wheezing, chest or throat tightness, difficulty breathing, swallowing or speaking, unusual hoarseness, or swelling of the mouth, face, lips, tongue, or throat—seek immediate medical attention.

Concomitant use with 5-fluorouracil in elderly patients may increase toxicity. Patients experiencing severe intestinal disorders, diarrhea, or dehydration should contact their physician.

Use during pregnancy should be based on a physician’s judgment, weighing the potential benefits to the mother against possible risks to the fetus.

Use during breastfeeding should be carried out under medical supervision.
