SAMe may interfere with how your Parkinsons medication is processed — effects are unpredictable.
SAMe is involved in catechol-O-methyltransferase (COMT) pathway and dopamine metabolism. May affect levodopa metabolism unpredictably.
Discuss SAMe use with your neurologist before starting. Monitor for changes in Parkinsons symptom control.
Take Levodopa as prescribed. SAMe can be taken with a meal, spaced 1-2 hours from the medication. Always inform your prescriber and pharmacist about all supplements — even "natural" products can affect drug metabolism, absorption, and efficacy.
Concurrent COMT inhibitors, unstable Parkinsons symptoms
Changes in motor symptoms, dyskinesia, wearing-off
Inform neurologist about SAMe supplementation.
