What do I do if I take too much folic acid?

If someone takes too much folic acid, emergency medical attention is important. You may also contact the local poison control office (1-800-222-1222). Symptoms include:
  • Nausea
  • Gas
  • Rash
  • Sleep problems
  • Irritability
  • Bitter taste

Folic acid is water soluble (dissolves in water), so excess amounts are removed in urine. Chronic high doses may cause problems for people taking anticonvulsants; high levels may lead to seizures.
