Spending the night with Optune GioTM

By: Osmond, Optune Gio patient ambassador

On top of living with glioblastoma (GBM), sleeping with Optune Gio can be its own separate beast. For me, it was the warm sensation on my head that originally threw me off. Then came the alarms when an array cord would come loose from the connection cable and box (CAD).

But luckily, I had a few tricks up my sleeve…

#1: Warm head, meet fan.

The warming sensation I feel when Optune Gio is on met its match with my trusty, old nightstand fan. In my first six months, the fan became a must for me. But truth be told, as time went on, I noticed the warm sensation less and less, and I eventually transitioned to being able to sleep without a fan.


#2: Beeping device, meet thoughtful placement. 

The beeping from the alarms was caused by device disconnection…and it was annoying. But the answer to my beeping issue was making sure that I had a long-enough cord in my bed. Now, I check and make sure that the curly cord has a good amount of slack, which allows me to freely move around as I sleep. I have found that having a longer cord in my bed leads to fewer interruptions and thus, less beeping.


#3: Fear of injury, meet strategic thinking.

Much like with my beeping issue, part of my safety concern was a matter of cord placement. I’ve found that hanging the device close by is best for me, as it allows for a looser cord.


I’m not always able to roll around in the bed a ton, but this method allows for better connection to Optune Gio. I personally have never struggled with any injuries related to Optune Gio or my cord. I believe that giving myself a lot of cord slack may be helping. Plus, I’m always looking for ways to keep my usage up and keep that blue light on.


#4: Difficulty falling asleep, meet…leveling expectations.

At first, I had trouble falling asleep. Optune Gio was just one more thing I had to worry about during the night, like my bathroom visits. Though once I was actually asleep, I don’t think it was necessarily of poorer quality—it’s just getting to sleep that can be difficult, in my opinion. I think this is simply something that some Optune Gio users may struggle with. The key is finding a way to adjust.

My big takeaway

The biggest piece of advice I could give someone would be to try to have patience that first month of using Optune Gio. In my experience, sleeping with Optune Gio became tolerable after the initial adjustment period. And the little fine-tuned adjustments I’ve made have been a huge help for me.


All in all, I think the most important thing to remember is to keep Optune Gio running when you can so that even in sleep, we can keep our usage up!


Sweet dreams, Osmond

Important Safety Information

What is Optune Gio® approved to treat?

Optune Gio is a wearable, portable, FDA-approved device indicated to treat a type of brain cancer called glioblastoma multiforme (GBM) in adult patients 22 years of age or older.

Newly diagnosed GBM

If you have newly diagnosed GBM, Optune Gio is used together with a chemotherapy called temozolomide (TMZ) if:

  • Your cancer is confirmed by your healthcare professional AND
  • You have had surgery to remove as much of the tumor as possible

Recurrent GBM

If your tumor has come back, Optune Gio can be used alone as an alternative to standard medical therapy if:

  • You have tried surgery and radiation and they did not work or are no longer working AND
  • You have tried chemotherapy and your GBM has been confirmed by your healthcare professional

Who should not use Optune Gio?

Optune Gio is not for everyone. Talk to your doctor if you have:

  • An implanted medical device (programmable shunt), skull defect (missing bone with no replacement), or bullet fragment. Optune Gio has not been tested in people with implanted electronic devices, which may cause the devices not to work properly, and Optune Gio has not been tested in people with skull defects or bullet fragments, which may cause Optune Gio not to work properly 
  • A known sensitivity to conductive hydrogels (the gel on the arrays placed on the scalp like the ones used on EKGs). When Optune Gio comes into contact with the skin, it may cause more redness and itching or may rarely cause a life-threatening allergic reaction

Do not use Optune Gio if you are pregnant or are planning to become pregnant. It is not known if Optune Gio is safe or effective during pregnancy.

What should I know before using Optune Gio?

Optune Gio should only be used after receiving training from qualified personnel, such as your doctor, a nurse, or other medical staff who have completed a training course given by Novocure®, the maker of Optune Gio.

  • Do not use any parts that did not come with the Optune Gio Treatment Kit sent to you by Novocure or given to you by your doctor
  • Do not get the device or transducer arrays wet
  • If you have an underlying serious skin condition on the scalp, discuss with your doctor whether this may prevent or temporarily interfere with Optune Gio treatment

What are the possible side effects of Optune Gio?

Most common side effects of Optune Gio when used together with chemotherapy (temozolomide, or TMZ) were low blood platelet count, nausea, constipation, vomiting, tiredness, scalp irritation from the device, headache, seizure, and depression. The most common side effects when using Optune Gio alone were scalp irritation (redness and itchiness) and headache. Other side effects were malaise, muscle twitching, fall and skin ulcers. Talk to your doctor if you have any of these side effects or questions.
