carbidopa/levodopa key facts
What dosages is carbidopa/levodopa available in?
carbidopa/levodopa is available as a 25 mg/100 mg and 50 mg/200 mg sustained release tablet.
What is carbidopa/levodopa used for?
carbidopa/levodopa is a dopa decarboxylase inhibitor / dopamine replacement and is used to treat the following:
- Parkinson’s disease (PD)
- Parkinsonism (conditions that cause people to have signs and symptoms of PD, including slowness, stiffness, shakiness, and imbalance)
How does carbidopa/levodopa work?
carbidopa/levodopa is a combination of two medications: carbidopa and levodopa. By working together, these medications help relieve symptoms of Parkinson’s disease (PD), which occur due to low dopamine levels in the brain. Levodopa is a dopamine replacement.
Levodopa travels into your brain, where it’s converted into dopamine. It helps relieve PD symptoms by restoring dopamine in your brain. Carbidopa is a dopa decarboxylase inhibitor.
Dopa decarboxylase is a protein in your body that breaks down levodopa before it can travel into your brain. By blocking this protein, carbidopa prevents levodopa from breaking down.
This raises the level of levodopa in your body and allows more levodopa to travel into your brain to be converted into dopamine. Levodopa and dopamine can then reach and remain at higher levels in your brain, which enhances levodopa’s ability to relieve PD symptoms.
How do I take carbidopa/levodopa?
carbidopa/levodopa is typically started at 50 mg/200 mg (carbidopa/levodopa) by mouth 2 times per day at least 6 hours apart.
Is it safe for me to take carbidopa/levodopa?
carbidopa/levodopa is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects. You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you. Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with carbidopa/levodopa. These inhibitors must be discontinued at least two weeks prior to initiating therapy with carbidopa/levodopa.
carbidopa/levodopa Common Side Effects
Common side effects of carbidopa/levodopa:
- Involuntary movements
- Nausea
carbidopa/levodopa Serious Side Effects
Serious side effects are rare with carbidopa/levodopa. Contact your healthcare provider immediately if you experience any of the following.
- Neuroleptic malignant syndrome (NMS): very high fevers, confusion, irregular pulse, sweating, muscle stiffness, changes in blood pressure
Effects of other drugs, drug classes and over-the-counter products on carbidopa/levodopa
The following medications may interact with carbidopa/levodopa:
- Symptomatic postural hypotension has occurred when carbidopa levodopa preparations were added to
- the treatment of patients receiving some antihypertensive drugs
- Concomitant therapy with selegiline and carbidopa levodopa may be associated with severe orthostatic hypotension not attributable to carbidopa levodopa alone
- There have been rare reports of adverse reactions, including hypertension and dyskinesia, resulting
- from the concomitant use of tricyclic antidepressants and carbidopa levodopa preparations
- Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone) and isoniazid may reduce the therapeutic effects of levodopa. In addition, the beneficial effects of levodopa in Parkinson’s disease have been reported to be reversed by phenytoin and papaverine. Patients taking these drugs with carbidopa/levodopa should be carefully observed for loss of therapeutic response
- Use of SINEMET with dopamine-depleting agents (e.g., reserpine and tetrabenazine) or other drugs known to deplete monoamine stores is not recommended
- carbidopa/levodopa and iron salts or multivitamins containing iron salts should be coadministered with caution. Iron salts can form chelates with levodopa and carbidopa and consequently reduce the bioavailability of carbidopa and levodopa
Who makes carbidopa/levodopa?
Various FDA-approved generic manufacturers
Is carbidopa/levodopa safe in pregnancy?
There are no adequate and well-controlled studies in pregnant women and carbidopa/levodopa should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

If you have Medicare Part D or Medicare Advantage and none of the carbidopa/levodopa savings options are applicable or affordable for me, what can you do?
If you are insured with Medicare and the carbidopa/levodopa drug savings options are not applicable to you and still remain unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and after you have selected your state, it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
People who qualify for both Medicare and Medicaid are called ‘dual eligibles’.
If you are denied Medicaid for carbidopa/levodopa, and you are still unable to afford your copay or co-insurance element (for example if you are in the coverage gap or Donut Hole) then you may be eligible for a federal support program like Low Income Subsidy. To be eligible for Low Income Subsidy, you need to be a resident in one of the 50 States or the District of Columbia. You can check eligibility online at SSA Medicare D Extra Help. You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778).
I am uninsured or underinsured and none of the carbidopa/levodopa prescription saving options are applicable or affordable for me, what can I do?
If you are uninsured or underinsured (for example, carbidopa/levodopa is not covered by your plan) and the drug savings options are not applicable or still unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and you can select your state and it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
If you are denied and all else fails, and if you have been prescribed carbidopa/levodopa for an FDA-approved indication, you can call the pharmaceutical company to see if they have any other assistance programs.
I am commercially or privately insured and none of the carbidopa/levodopa prescription saving options are applicable or affordable for me, what can I do?
If your medication is not covered by your plan, you can appeal your insurance company’s decision. Sometimes, a formal appeal can result in the drug being covered if it is deemed medically necessary.
If you cannot afford your copay contribution, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
However, being privately insured might complicate your eligibility for Medicaid, as having private insurance may be considered in the financial eligibility assessment.
The government site is easy to use and you can select your state and it will navigate you to the appropriate contact point to make the application. If you qualify, state Medicaid may cover the full cost of your medication.
