What is Rytary?

Rytary contains a combination of carbidopa and levodopa.

Rytary extended release capsules are used to treat symptoms of Parkinson's disease, such as muscle stiffness, tremors, spasms, and poor muscle control. Parkinson's disease may be caused by low levels of a chemical called dopamine (DOE pa meen) in the brain.

Rytary is also used to treat Parkinson symptoms caused by carbon monoxide carbon monoxide poisoning or manganese intoxication.

Warnings

You should not use Rytary if you have narrow-angle glaucoma.

Do not use Rytary if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, or tranylcypromine.

How should I take Rytary

Take Rytary exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

If you already take levodopa, you must stop taking it at least 12 hours before you start taking Rytary.

Rytary can be taken with or without food. Take your doses at regular intervals to keep a steady amount of the drug in your body at all times.

Swallow the capsule whole and do not crush, chew, break, or open it.

It may take up to several weeks of using Rytary before your symptoms improve. For best results, keep using the medication as directed. Talk with your doctor if your symptoms do not improve after a few weeks of treatment. Also tell your doctor if the effects of this medication seem to wear off quickly in between doses.

If you use Rytary long-term, you may need frequent medical tests.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Rytary.

Do not stop using Rytary suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.

Store at room temperature away from moisture, heat, and light.

Dosing information

Usual Adult Dose for Parkinson's Disease:

Optimum dosage is determined by careful individual titration: All doses expressed as CARBIDOPA-LEVODOPA

Rytary extended-release capsules:
-Initial dose (levodopa-naive): 23.75 mg-95 mg orally 3 times a day for 3 days; on the fourth day, may increase to 36.25 mg-145 mg 3 times a day
-Dosing interval may be increased up to a maximum of 5 times a day, if tolerated
-Maximum daily dose: 612.5 mg-2450 mg
Conversion from IMMEDIATE-RELEASE carbidopa-levodopa to Rytary: These recommended starting doses should be divided and given three times a day:
-For patients receiving levodopa 400 to 549 mg/day: total daily dose of levodopa in Rytary - 855 mg/day
-For patients receiving levodopa 550 to 749 mg/day: total daily dose of levodopa in Rytary - 1140 mg/day
-For patients receiving levodopa 750 to 949 mg/day: total daily dose of levodopa in Rytary - 1305 mg/day
-For patients receiving levodopa 950 to 1249 mg/day: total daily dose of levodopa in Rytary - 1755 mg/day
-For patients receiving levodopa equal or greater than 1250 mg/day: Rytary levodopa dose should be 2205 or 2340 mg/day

Comments:
-Peripheral dopa decarboxylase is saturated by carbidopa at approximately 70 to 100 mg/day; patient's receiving less than this amount of carbidopa are more likely to experience nausea and vomiting; experience with carbidopa doses greater than 200 mg/day is limited.
-Rytary products are not interchangeable with other carbidopa-levodopa products; for patients receiving carbidopa-levodopa plus catechol-O-methyl transferase (COMT) inhibitors, the initial recommended total daily dose of levodopa may need to be increased.

Use: For the treatment of the symptoms of idiopathic Parkinson's disease, postencephalitic parkinsonism, and symptomatic parkinsonism which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication.

What happens if I miss a dose?
