Leucovorin Side Effects and Adverse Reactions
Like all medications, Leucovorin can cause side effects. Some are more common than others. If you experience any severe side effects, contact your healthcare provider immediately.
Common Side Effects: Nausea, vomiting, diarrhea, fatigue
Less Common Side Effects: Allergic reactions (rash, itching, swelling), mouth sores
Rare but Serious Side Effects: Severe allergic reactions, difficulty breathing, chest pain
Contraindications
A contraindication is a specific situation where a drug should not be used because it may be harmful to the patient. If you have any of the following conditions or factors, you should not take Leucovorin. Always consult with your healthcare provider before starting any new medication, and if you are unsure, you can schedule a telemedicine appointment with one of our providers.
Pernicious anemia or other megaloblastic anemias due to vitamin B12 deficiency: Leucovorin can mask the symptoms of vitamin B12 deficiency, potentially delaying diagnosis and treatment, which can lead to serious neurological damage.
Known hypersensitivity to Leucovorin: If you have had an allergic reaction to Leucovorin in the past, taking it again could cause a severe allergic response, including rash, difficulty breathing, or anaphylaxis.
Drug to Drug Interactions
Leucovorin can interact with other medications, potentially altering how they work or increasing the risk of side effects. Be sure to inform your healthcare provider about all the medications you are taking, including over-the-counter drugs and supplements. Below are some common medications that may interact with Leucovorin:
Trimethoprim-sulfamethoxazole (Bactrim): This antibiotic is used to treat bacterial infections. Leucovorin may reduce its effectiveness, particularly in treating Pneumocystis jirovecii pneumonia (PJP).
Fluorouracil (Adrucil): Leucovorin is often used with this chemotherapy drug to enhance its effects, but the combination can increase the risk of severe side effects, such as diarrhea and mouth sores.
Phenobarbital (Luminal): This medication is used to control seizures. Leucovorin may reduce its effectiveness, potentially leading to an increased risk of seizures.
Phenytoin (Dilantin): Used to control seizures, phenytoin levels may be reduced when taken with Leucovorin, which could increase the risk of seizures.
Capecitabine (Xeloda): Leucovorin is sometimes used with this chemotherapy drug to enhance its effectiveness, but it can also increase the risk of side effects, such as severe diarrhea and hand-foot syndrome.
Leucovorin in Pregnancy
Is it safe to take Leucovorin when pregnant?
Leucovorin, also known as folinic acid, is generally considered safe during pregnancy, particularly when used to counteract the toxic effects of methotrexate or to enhance the effectiveness of certain chemotherapy drugs. However, as with any medication, it’s important to carefully weigh the potential benefits and risks. Always consult your healthcare provider before taking Leucovorin if you are pregnant. If you have any concerns, you can schedule a telemedicine appointment with one of our providers to discuss your options in more detail.
Leucovorin while Breastfeeding
Is it safe to take Leucovorin while breastfeeding?
Leucovorin is generally considered safe for use while breastfeeding, though there is limited data on its effects on breast milk and the nursing infant. If you are breastfeeding and need to take Leucovorin, it’s essential to consult your healthcare provider to ensure it’s the best choice for both you and your baby. Our telemedicine providers are available to help you make an informed decision based on your specific situation.

Possible Alternatives to Leucovorin
If Leucovorin is not the right treatment for you, or if you’re exploring other options, there are alternative treatments and lifestyle changes that may be beneficial. Always discuss any changes to your treatment plan with your healthcare provider. You can also schedule a telemedicine appointment with one of our providers to explore alternatives tailored to your needs.
Colorectal Cancer
Alternatives to Leucovorin include chemotherapy agents such as oxaliplatin (Eloxatin) or irinotecan (Camptosar). In some cases, targeted therapies like bevacizumab (Avastin) or immunotherapy may be considered. Additionally, lifestyle changes, such as adopting a fiber-rich diet and engaging in regular physical activity, can support overall health during treatment.
Osteosarcoma
Other chemotherapy drugs, such as doxorubicin (Adriamycin) or cisplatin, may be used in place of Leucovorin. Surgery and radiation therapy are also common treatment options. Incorporating a balanced diet and physical therapy into your recovery plan can help improve your quality of life.
Methotrexate Toxicity
If Leucovorin is unavailable, glucarpidase (Voraxaze) may be used to lower methotrexate levels. Monitoring kidney function and staying well-hydrated are crucial steps in preventing toxicity.
Acute Lymphoblastic Leukemia (ALL)
Other chemotherapy drugs, such as vincristine or prednisone, may be used as alternatives. Bone marrow transplants and targeted therapies are also potential options. Maintaining a healthy diet and managing stress can support your overall well-being during treatment.
Non-Hodgkin Lymphoma
Alternatives include rituximab (Rituxan) and chemotherapy regimens like CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone). Regular exercise and a nutritious diet can help boost energy levels and improve overall health during treatment.
Malignant Pleural Mesothelioma
Other treatment options include pemetrexed (Alimta) and cisplatin. Surgery and radiation therapy may also be considered. Quitting smoking and adopting a healthy lifestyle can enhance lung function and overall health.
Breast Cancer
Alternatives to Leucovorin include chemotherapy drugs like paclitaxel (Taxol) or targeted therapies such as trastuzumab (Herceptin). Hormonal therapies may also be part of the treatment plan. Maintaining a healthy weight, exercising regularly, and limiting alcohol intake can help reduce the risk of recurrence.
Head and Neck Cancer
Other treatment options include radiation therapy, surgery, and chemotherapy drugs like cisplatin or carboplatin. Quitting smoking and reducing alcohol consumption are important lifestyle changes that can improve treatment outcomes.
Gastric Cancer
Alternatives include chemotherapy drugs like oxaliplatin or targeted therapies such as trastuzumab (Herceptin). A healthy diet and regular physical activity can support your overall health during treatment.
Testicular Cancer
Other chemotherapy drugs, such as bleomycin, etoposide, and cisplatin (BEP regimen), may be used. Surgery and radiation therapy are also common treatments. Leading a healthy lifestyle, including regular exercise and a balanced diet, can aid in recovery and improve overall well-being.
Recent Updates on Leucovorin Research
Recent research on Leucovorin has focused on its role in enhancing the effectiveness of chemotherapy drugs, particularly in colorectal cancer and other solid tumors. Studies have shown that Leucovorin can improve the efficacy of fluorouracil (5-FU) in treating colorectal cancer, leading to better patient outcomes. Additionally, ongoing research is exploring the potential of Leucovorin in combination with newer targeted therapies and immunotherapies to further improve cancer treatment results.
Researchers are also investigating Leucovorin’s ability to reduce the side effects of methotrexate in patients with autoimmune diseases like rheumatoid arthritis. Early findings suggest that Leucovorin may help alleviate gastrointestinal and liver-related side effects, making methotrexate more tolerable for patients.
As new studies continue to emerge, staying informed about the latest developments in Leucovorin research is important. If you have questions about how these updates may impact your treatment plan, consider scheduling a telemedicine appointment with one of our providers to discuss the latest options available to you.
