Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Inbrija (levodopa) and Apokyn (apomorphine) are both used to manage "off" episodes in people with Parkinson's disease, but they have several differences. Inbrija is an anti-Parkinson agent that you inhale, and it works by replacing dopamine in the brain. It can be used up to 5 times a day and starts working in about 10 minutes. On the other hand, Apokyn is a dopamine agonist that you inject under the skin. It activates dopamine receptors and usually starts working within 20 minutes. Apokyn can cause severe nausea and vomiting, so you might need to take another medication to help with these side effects. Inbrija can cause coughing and darken your saliva, while Apokyn can cause low blood pressure and injection site reactions. Both medications require a prescription. Only Apokyn is available as a lower-cost generic.
Inbrija (levodopa) is used to treat "off" episodes (periods when your medications are wearing off so your Parkinson's symptoms come back) in people with Parkinson's disease (PD). It comes as an inhaler that can be used as needed up to 5 times per day, but it can cause cough and darken your spit, saliva, and sweat.
