APPLYING THE ARRAYS
All about arrays
Optune Gio delivers therapy through 4 adhesive patches, called transducer arrays. These arrays are applied to your scalp.

Removing the arrays
“The first time I did it, I was pretty nervous. But I was determined I was going to make it work. After that, I just know where the arrays go and I don’t worry so much about that eighth of an inch or quarter-inch that some people may worry about.”
– Sherry, Optune Gio user and Patient Ambassador
How often should I change the arrays?
Transducer arrays must be changed at least 2 times per week (one set of arrays should not be worn for more than 4 days at a time). However, more frequent transducer array changes are recommended if:
The weather has been warmer, causing you to sweat more
Your hair grows quickly. As your hair grows, it prevents the arrays from making good contact with your scalp
You’ve performed intense physical activity, causing you to sweat more
You’re experiencing discomfort, intense itching, or lots of oiliness on your scalp
The hydrogel layer over the ceramic discs becomes soft or “gooey” because of lots of moisture on your scalp
Time-saving tips for array changes
- Prep the arrays ahead of time so they’re ready to be placed
- Create an array change area in your home so that all of your supplies can live in one place
