| Possible Interactions
with: Phenylalanine |
|
|
If you are currently being treated with any of the following medications, you
should not use phenylalanine without first talking to your healthcare
provider.
Antidepressant Medications, Monoamine Oxidase Inhibitors
(MAOIs)
Phenylalanine may cause a severe increase in blood pressure
in people taking MAOIs (such as phenelzine, tranylcypromine, pargyline, and
selegiline). This severe increase in blood pressure (also called
"hypertensive crisis") can lead to a heart attack or stroke. For this reason,
individuals taking MAOIs should avoid foods and supplements containing
phenylalanine.
Baclofen
The absorption of baclofen, a medication used to
relieve muscle spasms, may be reduced by phenylalanine. Therefore, it is best to
avoid taking this medication with a meal, especially one that is high in protein
content, or with phenylalanine supplements.
Levodopa
A few case reports suggest that phenylalanine may
reduce the effectiveness of levodopa, a medication used to treat Parkinson's
disease. Some researchers speculate that phenylalanine may interfere with the
absorption of this medication. Therefore, phenylalanine should not be taken at
the same time as levodopa. |
