If you experience any of the following symptoms when taking leucovorin, call your doctor immediately:

an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives)
vomiting, diarrhea, or mouth sores
seizures
fainting
 

No other side effects have been reported from the use of leucovorin alone. Side effects are usually caused by the patient's chemotherapy, not by leucovorin.
