If you are pregnant, planning to become pregnant, nursing a baby, allergic to butterbur, or have liver disease, you should not use Preventa Migraine.Preventa Migraine may interfere with Doxorubicin, a medication used for the treatment of certain cancers, so please consult with your doctor prior to taking Preventa Migraine to see if it is right for you. If you are taking Tetracycline, an antibiotic, you should take Preventa Migraine at a different time during the day from when you take the Tetracycline because Vitamin B (an ingredient in Preventa Migraine) could decrease effectiveness when taken together.

Not all Butterbur remedies are the same and not all of them are safe. The Butterbur plant in its un-purified powder form contains natural pyrrolizidin alkaloids (PAs) which may cause liver damage or liver cancer. Preventa Migraine is PA free, we use Butterbur Root with the PA's removed from the extract via non-chemical ion exchange, which removes nothing from the extract except the PAs and 2 to 3% of its minerals, ensuring the highest quality product with less than 1 ppm of PAs. Preventa Migraine is also manufactured in our GMP certified facility located in the United States.
Riboflavin is generally considered safe, even at high doses. Riboflavin is water soluble meaning that the body does not store it and expels it via urine, often causing a bright yellow color.
