Reading size

How this medicine works

The current label explains that levodopa crosses the blood-brain barrier and is converted to dopamine in the brain, while carbidopa does not readily cross and mainly inhibits peripheral levodopa decarboxylation, leaving more levodopa available to reach the brain. RYTARY also combines immediate- and extended-release components for a specific release profile. This explains two ingredients and the extended-release design but cannot produce an individual conversion table, suitability decision or capsule count.

Check the market, names, dosage form and route together

A medicine may use different brand names across markets. Keep the market, brand, generic name, dosage form and route together; one matching field does not prove that two packs are the same or interchangeable.

Use these fields when the pack, market name or package image needs closer checking. They are evidence boundaries, not substitution instructions.

FOR EVERYDAY QUESTIONS

After the leaflet, continue with the question you still need to check

What this pack is

RYTARY is the brand name in this record; carbidopa and levodopa extended-release capsules is the generic name. Read both together with the dosage form (oral capsule).

What this page can show

This is a source-traceable public record. It helps you read the product identity and its listed source documents; each market still needs its own current record check.

What to bring to the next conversation

Bring the actual pack, the label or prescription, and a complete medicine list when you speak with a pharmacist or clinician.

PRODUCT PRESENTATION IDENTITY

Strength, pack and device identity

Package strength is not an individual dose. These fields help identify the exact labelled product; they do not calculate how much, how often, a missed-use action, splitting, switching or conversion.

How to read a score line: ‘scored’ or ‘unscored’ first identifies this labelled presentation. A score line by itself does not permit self-splitting, reducing or changing the product. Only an explicit statement in the current label for this exact presentation, checked with a pharmacist against the prescription, can support any further handling.

14 source-backed strength, pack or device records — open the full list

First match the market, dosage form and labelled amount on the pack in hand. The number of tablets, sachets or devices in a pack is not a personal dose or schedule.

LABEL READING · NOT A PRESCRIPTION

RYTARY label reading: the extended-release capsule cannot be halved; swallowing difficulty requires the entire contents

Reading level: drug-specific label reading. This record has been expanded around its dosage form or a higher-risk reading question; the current target-market label and professional review still apply.

Each paired strength states carbidopa and levodopa in one capsule. Opening the capsule onto applesauce is a current-label administration option for swallowing difficulty using the entire contents; it is not permission to halve a dose, estimate pellets or alter extended release generally. RYTARY cannot be self-converted with SINEMET, STALEVO, CREXONT or another product from shared ingredients or milligrams.

  • The label says to swallow the capsule whole and not chew, divide or crush it or grind the pellets. For swallowing difficulty, the label allows carefully opening both halves, sprinkling the entire contents on 1–2 tablespoons of applesauce and consuming it immediately. Do not store it or take only part. Have a pharmacist or prescriber review a different actual product, food requirement or swallowing limitation.
  • RYTARY is not interchangeable with other carbidopa/levodopa products. SINEMET is an immediate-release tablet; STALEVO also contains entacapone; CREXONT, DHIVY, DUOPA and VYALEV have different forms or delivery systems. Do not self-combine, alternate by day, convert or substitute from total levodopa milligrams, paired numbers, appearance or an old prescription.
  • Do not suddenly stop or rapidly reduce RYTARY. The label describes hyperpyrexia, muscular rigidity, altered consciousness and autonomic instability after rapid reduction, withdrawal or changes in dopaminergic therapy. Use local emergency services immediately for high fever, marked rigidity, altered consciousness, breathing or circulatory instability, and take the pack and complete medicine list.
  • Sudden sleep during daily activities, marked somnolence or dizziness may impair driving or machinery use. Hallucinations, psychotic symptoms, intense urges involving gambling, spending, sex or eating, and new involuntary movements also require prompt contact with the care team. Family or carers may notice these changes first. The site does not adjust treatment from these symptoms.
  • The 2026 label added a warning about vitamin B6 deficiency and associated seizures. Depression, confusion, cheilosis, glossitis, dermatitis, anaemia, neuropathy or seizures needs clinical assessment; use local emergency services for a seizure, loss of consciousness or ongoing convulsions. Do not use the site to arrange testing, high-dose B6 supplementation, stopping or switching.
  • Nonselective MAO inhibitors such as phenelzine or tranylcypromine, including use within the past two weeks, form a labelled contraindication boundary. Iron salts or iron-containing multivitamins may reduce bioavailability; high-fat, high-calorie meals may delay absorption, and high-protein meals may also affect levodopa absorption. Do not self-stop medicines, change meals, schedule separation or remove supplements; have a pharmacist review the full list and usual diet.
  • The label also addresses cardiovascular ischaemic events, upper gastrointestinal bleeding risk with prior peptic ulcer and intraocular-pressure monitoring in glaucoma. Use local urgent or emergency care for chest pain, severe breathlessness, fainting, vomiting blood or black stools, acute visual change or another serious presentation; the site does not continue, pause or change a strength for an individual.

Check safety information in the right market

Start with the public label or product record linked to this dossier, then use the official safety routes below for the market that applies to the medicine in hand.

Match five details before using a safety record

  1. Brand and generic nameBoth must match the medicine named by the record.
  2. Dosage form and strengthTablet, capsule, injection, inhaler, patch and eye drop are not interchangeable.
  3. Market and notice dateA record applies only to the country or region and date it names.
  4. Lot, pack and manufacturerRecord these only when the official notice specifically names them.
  5. Current product informationA historical record may have been superseded by the current label.

This checklist only helps organise the right question. It does not create a personal conclusion about stopping, switching, dose, combination or suitability.

  • FDA Drug Safety Communication: vitamin B6 deficiency and seizures warning for RYTARY and other carbidopa/levodopa products2026-03-20 · On 20 Mar 2026, FDA issued a Drug Safety Communication requiring every carbidopa/levodopa product to add a warning about vitamin B6 deficiency and associated seizures; the current RYTARY label includes this warning. The communication cannot determine an individual's vitamin B6 status, need for testing or supplementation, and does not support self-stopping, switching to SINEMET or STALEVO, changing capsule counts or altering timing. Use local emergency services for a seizure, loss of consciousness or ongoing convulsions; have the prescribing team assess other suspected symptoms using the exact product and complete medicine list.FDA: 20 Mar 2026 Drug Safety Communication on vitamin B6 deficiency and seizures with carbidopa/levodopa products ↗reviewed 2026-08-22

This card brings together the medicine-specific product route and 15 market-level official vigilance gateways. It does not mean real-time alerts for this medicine have been searched in every country or region, or that the medicine has a new alert, recall or risk conclusion. Match brand, generic name, dosage form, strength, market and notice date item by item; do not self-stop, switch, increase or reduce use from a headline.

For severe or rapidly worsening symptoms, suspected overdose, a severe allergic reaction, loss of consciousness or another emergency, use local emergency services. Do not wait for an online alert search or change a medicine from this page.

PACK · LABEL · MEDICINE LIST

Six checks for this medicine pack

Use this card to organise questions about RYTARY (carbidopa and levodopa extended-release capsules). Keep the exact pack, its current label and the full medicine list together.

  1. Identify the exact product

    RYTARY is the brand in this record and carbidopa and levodopa extended-release capsules is the active-ingredient name. Check both with the dosage form (Carbidopa/levodopa fixed two-ingredient extended-release oral capsules: 23.75/95, 36.25/145, 48.75/195 and 61.25/245 mg; each paired strength states the two ingredients in one capsule and is not a milligram conversion table for SINEMET immediate-release tablets or another extended-release product) and the market on the actual pack.

  2. Read the labelled strength in context

    mg, mcg, mg/mL or a percentage describes the labelled amount in one tablet, capsule, measured volume, spray or other unit. It is not an answer to how many units a person should take.

  3. Check before splitting or opening

    Before splitting, crushing, chewing or opening anything, find an explicit instruction for this exact product in its current label and ask a pharmacist. A score line or a previous pack is not enough by itself.

  4. Put every product on one list

    Include prescriptions, over-the-counter products, eye drops, creams, vitamins, minerals, herbs and supplements. A pharmacist or prescriber needs the whole list before any combination, alternation, switch or stop is considered.

  5. Ask a specific pharmacogenetics question

    Ask which medicine, which gene and what clinical decision a result could change. A gene–drug association does not mean broad genetic testing is needed for everyone and must not be used to change treatment without professional review.

  6. Know when to seek urgent help

    For a suspected overdose, a severe allergic reaction, fainting or difficulty breathing, use the local emergency or poison-information service now. Do not wait for a website reply or alter several medicines to test what caused it.

This card does not calculate a dose, decide whether medicines can be combined, or replace a clinician or pharmacist. Market-specific current labels and the person's full context still need review.

MARKET DOCUMENTS · READ SEPARATELY

Enlarged market leaflets and regulator documents

Each link retains its own market, date, dosage form and document status. These documents support larger-print reading and item-by-item checking; they do not make products, strengths, packs, indications or use between countries or regions interchangeable.

HOW IT WORKS · NOT A TREATMENT PLAN

How the two ingredients work together: levodopa reaches the brain to form dopamine while carbidopa mainly reduces peripheral breakdown

  • Shared generic ingredients do not create the same release profile. RYTARY, SINEMET, Sinemet CR and CREXONT have different dosage-form designs; per-capsule or per-tablet milligrams cannot simply be added and treated as equivalent.
  • Opening the capsule and sprinkling all pellets on applesauce does not mean destroying the extended-release pellets. Chewing, crushing, grinding, taking only part or storing the mixture crosses the label boundary.
  • Mechanism cannot determine an individual's on/off timing, need for a formulation change, missed-use response or suitability for genetic screening. Parkinson treatment and polypharmacy require the treating team to review the actual product, symptom record and complete medicine list.

DOCUMENT TIMELINE

Document timeline

  1. Four RYTARY extended-release capsule strengths approved

    The FDA original approval letter confirms approval of NDA 203312 strengths 23.75/95, 36.25/145, 48.75/195 and 61.25/245 mg; current Orange Book data still list four prescription RLD products.

  2. FDA issued vitamin B6 deficiency and seizure safety communication

    The communication covers carbidopa/levodopa products and requires corresponding label updates; it does not determine an individual's deficiency, supplementation need or whether treatment should be stopped.

  3. Current DailyMed page updated

    SPL v26 lists four strengths, fourteen active structured package NDCs, four exact 100-capsule bottle panels, capsule-opening/applesauce instructions and expanded safety information.

MARKET SCOPE

Market-record boundary

United States

Four prescription RLD products; 61.25/245 mg is also RS; current SPL lists fourteen active package NDCs

Four 100-capsule NDC -01 bottles have exact display panels; the remaining packs retain text identity. No record establishes real-time stock, purchasing eligibility, individual suitability or interchangeability with another carbidopa/levodopa product.

Mainland China and other markets

Current market record not established

No local approval, trade name, pack, supply or interchangeability is inferred from the U.S. brand, shared ingredients, colours or paired numbers.

How to read this record

Read each document in its stated market, date and dosage-form context. A historical record is not a current label and does not support individual medical, substitution or purchasing conclusions.

Keep international and mainland China records separate

This page has a U.S. public history/regulatory archive but no mainland China record for this specific product. That does not establish whether the medicine exists, is approved or is available in mainland China. Verify product identity, dosage form, strength, holder and the current label item by item.

RECORD FAQ

Record questions

Can a RYTARY capsule be opened and half taken?

No. The current label allows opening for swallowing difficulty only when the entire contents of both halves are sprinkled on a small amount of applesauce and consumed immediately. Do not halve, estimate pellets, crush, chew or save them. Any individual adjustment belongs with the prescribing team.

Can RYTARY and SINEMET milligrams be converted directly?

No. The label states that RYTARY is not interchangeable with other carbidopa/levodopa products; release design and prescribed conversion rules differ. The site provides no individual conversion table. Take both packs, prescribed schedule and symptom record to the treating team.

Why can one strength have several bottle NDCs but only one image?

The current SPL structured package data list several active NDCs per strength, while official display panels correspond only to four 100-capsule NDC -01 bottles. The site therefore keeps text-only identity cards for the other NDCs rather than reusing a potentially misleading image.
