Interactions for Vitamin B6 (Pyridoxine)
Possible Interactions with
Vitamin B6 (Pyridoxine)
Overview
Anti-tuberculosis medications such as isoniazid (INH) and cycloserine (used
for resistant forms of tuberculosis) reduce the levels of vitamin B6
in the blood. For this reason, it is recommended that you take vitamin
B6 if you are taking these medications and that your doctor closely
monitor you for signs of vitamin B6 deficiency.
Additionally, vitamin B6 reduces the therapeutic effect of
levodopa, a medication used to treat Parkinson's disease.
Penicillamine (used in the treatment of Wilson's disease and rheumatoid
arthritis) decreases levels of vitamin B6 and may render this vitamin
ineffective.
Long-term use of birth control medications may decrease blood levels of
vitamin B6.
Vitamin B6 diminishes the effectiveness of hydralazine, a
medication used for the treatment of high blood pressure.
Monoamine oxidase inhibitors, medications such as phenelzine and
tranylcypromine that are used to treat depression, may reduce blood levels of
vitamin B6.
