What does the patient leaflet for levodopa say first?

The FDA-approved Medication Guide or Patient Information that comes with the medicine, in its own words.

From the patient leaflet: What should I avoid while using INBRIJA?

Do not drive, operate machinery, or do other activities until you know how INBRIJA affects you. INBRIJA can cause sleepiness and falling asleep suddenly as late as 1 year after you start treatment.

From the patient leaflet: How should I store INBRIJA?

Store the inhaler and capsules in a dry place at room temperature between 68°F to 77°F (20°C to 25°C). Keep capsules in their foil (blister) packages until just before you are ready to use them. Do not store capsules inside the inhaler for a future dose. Keep the inhaler and capsules dry. Throw out the inhaler after all capsules in the carton have been used. Use the new inhaler that comes with your prescription refill. Keep INBRIJA and all medicines out of the reach of children.

Has levodopa been recalled?

The FDA's Enforcement Report lists 1 recall naming levodopa since 2015: 0 Class I (the most serious), 1 Class II, 0 Class III; 0 still ongoing. 1 of them is by a firm that FDA's NDC Directory does not list as a maker of levodopa and that holds no application for it in Drugs@FDA, such as compounding pharmacies or bulk-ingredient suppliers; the recall notice names the product recalled. A recall names products and lots, not every product of the medicine.

What do FAERS reports show for levodopa?

The FDA Adverse Event Reporting System holds 12,013 reports that list levodopa among the medicines taken, through July 30, 2026, each a report of something that happened, not proof the medicine caused it; 1,359 are coded as a death and 2,717 as a hospital stay. Counts follow how widely a medicine is used and watched, and they are not a measure of how risky it is. Reports rose sharply in 2021 (2,286, against a median of 531 a year): FAERS counts follow reporting, which news, litigation and label changes can drive, not how often a reaction happens.
