Table of Contents ▾

Do you sometimes feel like you're suddenly paralyzed, unable to move your limbs, and suddenly stop doing what you're doing? This may be a familiar experience for someone with Parkinson's disease. Doctors call these conditions 'off' periods. To be precise, they are times when the effects of the medications you usually take wear off and the symptoms return. Today we're talking about a special medication that can be used to provide quick relief at times like these. That's the Levodopa inhaler.

What is this Levodopa inhaler?

Simply put, this is a medication that is given to control the 'off' states that occur in the severe stages of Parkinson's disease. This is not a daily medication. It is used only when, as mentioned earlier, there is a sudden 'off' state where you cannot move or do anything.

This medicine comes in the form of capsules filled with a powder. These capsules are not good to swallow at all . They need to be used with a special inhaler that comes with it. It's like the inhaler people use for asthma, but this one is different. The famous brand name for this is INBRIJA.
