If you cannot tolerate Madopark, you could try Sinemet (carbidopa/levodopa) as your main medication, possibly in combination with entacapone (Stalevo/Sastravi).
Intolerance to, for example, Madopark may be temporary, and genuine intolerance (allergy or other cause) is extremely rare. During the initial phase of treatment with an L-dopa preparation, you can add 10 mg of domperidone, which can counteract, for example, nausea and gastrointestinal reactions during the early stages of L-dopa treatment; you can usually continue without this after 1–2 weeks of treatment. /Håkan Widner
