For some people, wearing-off can begin within one to two years of starting levodopa therapy; for others, levodopa may remain effective for five years or more. Everyone’s experience of Parkinson’s is different, so the wearing-off symptoms you notice are individual to you.
What are the problems of L-DOPA?
Patients treated with L-Dopa for more than five years had a greater neurological deficit score than patients who had not received L-Dopa. Besides a more severe course, these patients also exhibited significantly more dyskinesias and on-off-phenomena.
How is L-DOPA absorbed?
Levodopa is absorbed from the small intestine by the active transport mechanism for large neutral amino acids. A similar transport system transfers levodopa across the blood–brain barrier. Levodopa is extensively decarboxylated to dopamine in peripheral tissues such as the gut wall, liver and kidney.
How do you store L-DOPA?
L-DOPA is supplied as a crystalline solid. L-DOPA is sparingly soluble in water. We do not recommend storing the aqueous solution for more than one day. L-DOPA is a metabolic precursor of dopamine that is capable of crossing the blood brain barrier.
Does L-DOPA make you sleep?

Five decades after its introduction, L-DOPA is still the most effective and widely used drug to alleviate the symptoms of PD (4). In recent years, deep brain stimulation (DBS) has become a standard evidence-based therapy for severe movement disorders such as PD (5), tremor (6) and dystonia (7).
Is L-dopa safe long-term?
It provides the greatest antiparkinsonian benefit with the fewest adverse effects in the short term. However, long-term use of levodopa is associated with the development of fluctuations and dyskinesias. Once fluctuations and dyskinesias become problematic, they are difficult to resolve.
What foods are high in L-DOPA?
Broad beans (also called Velvet Beans) are a specific type of bean that has been found to be high in L-DOPA and support dopamine production. Yogurt, kefir, sauerkraut, and other fermented foods are rich in health-promoting bacteria called probiotics.
