How to take Carbidopa, entacapone, and levodopa?

Details on dosage
Adult dosage for Parkinson's disease:
Converting to Entacapone, Levodopa, and Carbidopa:
Switch to a combination tablet providing an equivalent dose.
Converting to Levodopa from Carbidopa
Patients with dyskinesias that are moderate to severe and taking levodopa at doses greater than 600 mg will likely require a lower dose of levodopa when entacapone has been added.
-Titrate the patient to a given dose by using a separate levodopa/carbidopa tablet plus entacapone. Then switch to the corresponding single-combination tablets.
Reduce the dose of levodopa by reducing tablet strength or increasing the time between doses.
Administering other anti-Parkinson drugs concurrently:
This drug or concomitant medication may need to be dose adjusted.
MAXIMUM DAILY DOSE
Do not exceed eight tablets per 24-hour period.
Stavo 200: Maximum 6 tablets per 24 hours
Comments:
Conversions to carbidopa and levodopa rely on the combination of carbidopa and levodopa in a ratio of 1:4. There is no experience in switching patients away from products not combined in this ratio or extended-release formulations.
The optimal dose can be determined through careful titration. Therapy should be tailored to each individual and adjusted according to the desired clinical response.
Use: To treat Parkinson's disease
As a replacement for the equal strengths of each component
If dyskinesias and signs of "wearing off" at the end of the dose are present, then levodopa, 600 mg daily or less, can be substituted for carbidopa or levodopa.
What happens if I miss the dose?
If you are almost due for your next dose, skip the missed one. Never take two doses of the same medicine at once.
What happens if I overdose?
Call 1-800-222-1222 for poison help or seek immediate medical attention. Rapid heartbeat and lightheadedness are two symptoms of overdose.
What should be avoided?
Do not drive or engage in hazardous activities until you have a better understanding of how levodopa and carbidopa affect you. You may have impaired reactions. You may feel dizzy if you get up quickly from a seated or lying position.
Do not take iron supplements without consulting with your physician first. Avoid increasing your intake of protein (proteins include eggs, cheese, meat, and other sources). Iron or too much protein may make it difficult for your body's ability to absorb and digest Stalevo.

Stalevo can make you more drowsy if taken with other drugs. Before taking an opioid, a sleeping tablet, a muscle-relaxing medication, or medicine to treat anxiety or seizures, consult your doctor.
