Possible Interactions with: Tyrosine
If you are currently being treated with any of the following medications, you should not use tyrosine supplements without first talking to your health care provider.
Monoamine Oxidase Inhibitors (MAOIs) -- Tyrosine may cause a severe increase in blood pressure in people taking the antidepressant medications known as MAOIs. This rapid increase in blood pressure (also called "hypertensive crisis") can lead to a heart attack or stroke. For this reason, people taking MAOIs should avoid foods and supplements containing tyrosine. MAOIs include:
- Isocarboxazid (Marplan)
- Phenelzine (Nardil)
- Tranylcypromine (Parnate)
Thyroid hormone -- Tyrosine is a precursor to thyroid hormone, so it might raise levels too high when taken with synthetic thyroid hormones.
Levodopa(L-dopa) -- No one should take tyrosine at the same time as levodopa, a medication used to treat Parkinson's disease because levodopa may interfere with the absorption of tyrosine.
