Lodosyn is a prescription medication used in combination with levodopa to treat symptoms of Parkinson's disease, such as shakiness, stiffness, or tremors. It contains the active ingredient carbidopa. When taken alone, Carbidopa does not influence these symptoms. Parkinson's disease is believed to be caused by a deficiency of the naturally occurring substance dopamine in the brain.
Carbidopa works by preventing the breakdown of levodopa in the bloodstream before it can reach the brain, allowing more of it to reach the brain and be converted into dopamine. This can help to improve Parkinson's symptoms. Carbidopa can also reduce the occurrence of some of levodopa's side effects, such as nausea and vomiting.
Use and Dosage
Carbidopa comes as a tablet medication that is taken orally with or without food, as directed by your doctor. Your doctor may direct you to take the tablet at the same time as one, some, or all your levodopa/carbidopa doses, carefully follow their instructions. Your dosage will be based on your medical condition and how you respond to the treatment.
The recommended dosage of carbidopa tablet may vary depending on your medical condition and how you respond to the treatment. According to Medscape, the initial dosage of carbidopa for levodopa-naive patients is 25 mg three or four times a day. The dosage may be increased or decreased by 1/2 or 1 tablet a day in accordance with the therapeutic and adverse responses observed. Dosage adjustments should be made by physicians familiar with the patient. However, consult with your doctor before making any changes to your medication regimen.
To get the most benefit from Carbidopa, it should be taken regularly at the same time(s) each day. Some patients may experience a "wearing-off" effect, where their symptoms worsen before the next dose is due, or an "on-off" effect, where sudden short periods of stiffness occur. If these effects occur, contact your doctor for possible dose adjustments that may help to lessen this effect.
Do not stop taking Carbidopa and the levodopa-containing product without consulting your doctor, as some conditions may become worse when these drugs are quickly reduced or suddenly stopped. If your doctor decides to stop your medication, they will likely gradually reduce your dosage over time to prevent any negative effects.
