Leucovorin is used to prevent harmful effects of methotrexate (Rheumatrex, Trexall; cancer chemotherapy medication) when methotrexate is used to to treat certain types of cancer. Leucovorin is also used to treat people who have accidentally received an overdose of methotrexate or similar medications. Leucovorin is in a class of medications called folic acid analogs. It works by protecting healthy cells from the effects of methotrexate or similar medications while allowing methotrexate to enter and and kill cancer cells.
Leucovorin comes as a tablet to take by mouth. It is usually taken every 6 hours until laboratory tests show it is no longer needed. Sometimes leucovorin is taken on a different schedule, depending on the reason it is needed. Take leucovorin at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take leucovorin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Before taking leucovorin,
Unless your doctor tells you otherwise, continue your normal diet.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Some side effects can be serious. If you experience any of these symptoms, call your doctor immediately:
Leucovorin may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online [at http://www.fda.gov/MedWatch/index.html] or by phone [1-800-332-1088].
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to leucovorin.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
