What is Levodopa RPh?
Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) combination is used to treat Parkinson's disease, sometimes called shaking palsy or paralysis agitans. Parkinson's disease is a disorder of the central nervous system (brain and spinal cord).
Extended-release Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) (Levodopa RPh®) is also used to treat parkinsonism caused by encephalitis, or parkinsonism caused by carbon monoxide or manganese poisoning.
Dopamine is a naturally occurring substance in the brain that helps provide control of movement and activities such as walking and talking. In patients with Parkinson's disease, there is not enough dopamine in some parts of the brain. Levodopa (Levodopa RPh) enters the brain and helps replace the missing dopamine, which allows people to function better. By increasing the amount of dopamine in the brain, Levodopa (Levodopa RPh) helps control symptoms and helps you to perform daily activities such as dressing, walking, and handling utensils.
Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) is available only with your doctor's prescription.
Levodopa RPh indications
Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets are indicated in the treatment of the symptoms of idiopathic Parkinson’s disease (paralysis agitans), postencephalitic parkinsonism, and symptomatic parkinsonism which may follow injury to the nervous system by carbon monoxide intoxication and/or manganese intoxication. Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets are indicated in these conditions to permit the administration of lower doses of Levodopa (Levodopa RPh) with reduced nausea and vomiting, with more rapid dosage titration, with a somewhat smoother response, and with supplemental pyridoxine (vitamin B6).
In some patients, a somewhat smoother antiparkinsonian effect results from therapy with Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) than with Levodopa (Levodopa RPh). However, patients with markedly irregular (“on-off”) responses to Levodopa (Levodopa RPh) have not been shown to benefit from Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) therapy.
Although the administration of Carbidopa (Levodopa (Levodopa RPh) RPh) permits control of parkinsonism and Parkinson’s disease with much lower doses of Levodopa (Levodopa RPh), there is no conclusive evidence at present that this is beneficial other than in reducing nausea and vomiting, permitting more rapid titration, and providing a somewhat smoother response to Levodopa (Levodopa RPh).
Certain patients who responded poorly to Levodopa (Levodopa RPh) have improved when Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) was substituted. This is most likely due to decreased peripheral decarboxylation of Levodopa (Levodopa RPh) which results from administration of Carbidopa (Levodopa (Levodopa RPh) RPh) rather than to a primary effect of Carbidopa (Levodopa (Levodopa RPh) RPh) on the nervous system. Carbidopa (Levodopa (Levodopa RPh) RPh) has not been shown to enhance the intrinsic efficacy of Levodopa (Levodopa RPh) in parkinsonian syndromes.
In considering whether to give Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets to patients already on Levodopa (Levodopa RPh) who have nausea and/or vomiting, the practitioner should be aware that, while many patients may be expected to improve, some do not. Since one cannot predict which patients are likely to improve, this can only be determined by a trial of therapy. It should be further noted that in controlled trials comparing Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) with Levodopa (Levodopa RPh), about half of the patients with nausea and/or vomiting on Levodopa (Levodopa RPh) improved spontaneously despite being retained on the same dose of Levodopa (Levodopa RPh) during the controlled portion of the trial.
How should I use Levodopa RPh?
Use Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) by mouth with or without food.
- If you take an iron product or a multivitamin that contains iron, ask your doctor or pharmacist how to take it with Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh). Iron may decrease your body's ability to absorb Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh).
- Diets that are high in some contents (eg, protein, fat, calories) may decrease your body's ability to absorb Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh). Discuss any questions or concerns with your doctor. Tell your doctor if you have a diet that is high in protein, fat, or calories or if you will be changing your diet.
- Carefully follow the dosing schedule given to you by your health care provider.
- Take Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) on a regular schedule to get the most benefit from it. Taking Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) at the same times each day will help you to remember to take it.
- Continue to take Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) even if you feel well. Do not miss any doses.
- If you have been taking Levodopa (Levodopa RPh), do not start taking Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) until at least 12 hours after your final dose of Levodopa (Levodopa RPh).
- Do not suddenly stop taking Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) or lower your dose without checking with your doctor. Side effects may occur. Discuss any questions or concerns with your doctor.
- If you miss a dose of Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh), take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh).
Uses of Levodopa RPh in details
This medication is used to treat symptoms of Parkinson's disease (such as shakiness, stiffness, difficulty moving).
Parkinson's disease is thought to be caused by too little of a naturally occurring substance (dopamine) in the brain. Levodopa (Levodopa RPh) changes into dopamine in the brain, helping to control movement. Carbidopa (Levodopa (Levodopa RPh) RPh) prevents the breakdown of Levodopa (Levodopa RPh) in the bloodstream so more Levodopa (Levodopa RPh) can enter the brain. Carbidopa (Levodopa (Levodopa RPh) RPh) can also reduce some of Levodopa (Levodopa RPh)'s side effects such as nausea and vomiting.
By giving this medication as a continuous infusion, it can help reduce the amount of "off" time (periods of slow movement or stiffness).
How to use Carbidopa (Levodopa (Levodopa RPh) RPh)-Levodopa (Levodopa RPh) via j-tube
Read the Medication Guide and the Instructions for Use provided by your health care professional before you start using this medication and each time you get a refill. If you have any questions, ask your health care professional.
Give this medication as directed as a continuous infusion into the small intestine using an infusion pump. It is usually given over 16 hours a day and stopped at bedtime. At bedtime, take your dose of immediate-release Levodopa RPh tablets by mouth as directed.
When you first start using this medication, it is given through a tube through the nose into the small intestine. After a few days, if the doctor decides that this product is right for you, then the medication will be given through a tube through the abdomen into the small intestine. Getting the tube through the abdomen will require surgery.
Follow all instructions from your health care professional about how to properly use this medication and the infusion pump. Take a cassette containing the medication from the refrigerator and leave it at room temperature for 20 minutes before using. Do not use a cassette for longer than 16 hours or re-use it, even if there is medication left in it. Learn how to store and discard medical supplies safely. Also learn how to properly care for the small hole in your abdomen and the skin area around the tube, and how to avoid infection.
The dosage is based on your medical condition and response to treatment. Your daily dose is made up of a morning dose, a continuous dose, and extra doses. An extra dose is a small dose of this medication that can be given as needed during the day to treat sudden "off" symptoms. Extra doses should not be given more often than one every 2 hours to avoid causing or worsening movements you cannot control.
Do not suddenly decrease the dose or suddenly stop using this medication because doing either may lead to a serious condition. If you must stop this medication, slowly reduce the dose as directed by your doctor. Contact your doctor right away if your infusion is interrupted. You may need to take the tablet form of Levodopa RPh by mouth.
If you plan to be disconnected from the pump for a short period of time (less than 2 hours, for example, to shower), ask your doctor ahead of time if you should use an extra dose of this medication before you disconnect. If you plan to be disconnected from the pump for longer than 2 hours, ask your doctor what you should do and discuss how you should take Levodopa RPh tablets by mouth during this time.
Avoid high-protein diets because they may reduce how much of the medication you can absorb.
Tell your doctor if your condition does not improve or if it worsens.
Levodopa RPh description
The naturally occurring form of dihydroxyphenylalanine and the immediate precursor of dopamine. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to dopamine. It is used for the treatment of parkinsonian disorders and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.
Levodopa RPh dosage
Dosage in Patients Naïve to Levodopa (Levodopa RPh) Therapy
The recommended starting dosage of Levodopa RPh in Levodopa (Levodopa RPh)-naïve patients is 23.75 mg / 95 mg taken orally three times a day for the first 3 days. On the fourth day of treatment, the dosage of Levodopa RPh may be increased to 36.25 mg / 145 mg taken three times a day.
Based upon individual patient clinical response and tolerability, the Levodopa RPh dose may be increased up to a maximum recommended dose of 97.5 mg / 390 mg taken three times a day. The dosing frequency may be changed from three times a day to a maximum of five times a day if more frequent dosing is needed and if tolerated. The maximum recommended daily dose of Levodopa RPh is 612.5 mg / 2450 mg.
Maintain patients on the lowest dosage required to achieve symptomatic control and to minimize adverse reactions such as dyskinesia and nausea.
Converting from Immediate-Release Carbidopa (Levodopa (Levodopa RPh) RPh)-Levodopa (Levodopa RPh) to Levodopa RPh
To convert patients from immediate-release Carbidopa (Levodopa (Levodopa RPh) RPh)-Levodopa (Levodopa RPh) to Levodopa RPh, determine the recommended starting dosage of Levodopa RPh using Table 1.
The dosages of other Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) products are not interchangeable with the dosages of Levodopa RPh.
Adjust the dose to maintain patient tolerance and sufficient symptomatic control. The dosing frequency may be changed from three times a day to a maximum of five times a day if more frequent dosing is needed and if tolerated. The maximum recommended daily dose of Levodopa RPh is 612.5 mg / 2450 mg.
For patients currently treated with Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) plus catechol-O-methyl transferase (COMT) inhibitors (such as entacapone), the initial total daily dose of Levodopa (Levodopa RPh) in Levodopa RPh described in Table 1 may need to be increased.
Use of Levodopa RPh in combination with other Levodopa (Levodopa RPh) products has not been studied.

Discontinuation of Levodopa RPh
Avoid sudden discontinuation or rapid dose reduction of Levodopa RPh. The daily dose of Levodopa RPh should be tapered at the time of treatment discontinuation.
Administration Information
Swallow Levodopa RPh whole with or without food. A high-fat, high-calorie meal may delay the absorption of Levodopa (Levodopa RPh) by about 2 hours.
Do not chew, divide or crush Levodopa RPh capsules. For patients who have difficulty swallowing intact capsules, administer Levodopa RPh by carefully opening the capsule, sprinkling the entire contents on a small amount of applesauce (1 to 2 tablespoons), and consuming immediately. Do not store the drug/food mixture for future use.
Levodopa RPh interactions

What other drugs will affect Levodopa RPh?
Monoamine Oxidase (MAO) Inhibitors
The use of nonselective MAO inhibitors with Levodopa RPh is contraindicated. Discontinue use of any nonselective MAO inhibitors at least two weeks prior to initiating Levodopa RPh.
The use of selective MAO-B inhibitors (e.g., rasagiline and selegiline) with Levodopa RPh may be associated with orthostatic hypotension. Monitor patients who are taking these drugs.
Antihypertensive Drugs
The concurrent use of Levodopa RPh with antihypertensive medications can cause symptomatic postural hypotension. A dose reduction of the antihypertensive medication may be needed after starting or increasing the dose of Levodopa RPh.
Dopamine D2 Receptor Antagonists And Isoniazid
Dopamine D2 receptor antagonists (e.g., phenothiazines, butyrophenones, risperidone, metoclopramide, papaverine) and isoniazid may reduce the effectiveness of Levodopa (Levodopa RPh). Monitor patients for worsening Parkinson's symptoms.
Iron Salts
Iron salts or multi-vitamins containing iron salts can form chelates with Levodopa (Levodopa RPh), Carbidopa (Levodopa (Levodopa RPh) RPh), and can cause a reduction in the bioavailability of Levodopa RPh. If iron salts or multi-vitamins containing iron salts are co-administered with Levodopa RPh, monitor patients for worsening Parkinson's symptoms.
High-Protein Diet
Because Levodopa (Levodopa RPh) competes with certain amino acids for transport across the gut wall, the absorption of Levodopa (Levodopa RPh) may be decreased in patients on a high-protein diet. Advise patients that a high-protein diet may reduce the effectiveness of Levodopa RPh.
Levodopa RPh side effects

What is the most important information I should know about Levodopa RPh?
Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets. These inhibitors must be discontinued at least two weeks prior to initiating therapy with Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets. Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets may be administered concomitantly with the manufacturer’s recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCI).
Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets are contraindicated in patients with known hypersensitivity to any component of this drug, and in patients with narrow-angle glaucoma.
Because Levodopa (Levodopa RPh) may activate a malignant melanoma, Carbidopa (Levodopa (Levodopa RPh) RPh) and Levodopa (Levodopa RPh) orally disintegrating tablets should not be used in patients with suspicious, undiagnosed skin lesions or a history of melanoma.
