Showering and bathing with Optune Lua™

How do I shower or bathe while I use Optune Lua?

There are 2 ways to clean your upper body:

A sponge bath with your arrays still on

  • Unplug the arrays from Optune Lua

A full shower with your arrays completely removed

  • Unplug the arrays from Optune Lua
  • Take a normal shower once your arrays have been unplugged and completely removed from your body*

*Leave Optune Lua outside the bathroom while taking a sponge bath or a full shower.

How long to use Optune Lua™

How long should I use Optune Lua?

  • It is recommended that Optune Lua be turned on at least 75% of the time (18 hours per day) to get the best response from your treatment
  • You can choose which parts of the day to have your treatment, including at night when you are sleeping

Transducer array replacement

  • At least twice per week to help minimize the risk of skin irritation
Shaving guidelines

Why do I have to shave my upper body while using Optune Lua?

  • Transducer arrays need to be applied directly to your skin to work properly. Even a small amount of hair growth can prevent the arrays from making good contact with your skin
  • You will need to shave upper body and change the arrays at least 2 times a week (or every 4 days at most)
  • An array applicator will be provided to help place transducer arrays onto your skin

Regular clothes (loose fitting) may be worn over the arrays.

The Optune Lua™ device

How will I know if Optune Lua is working?

  • Make sure the transducer arrays are in position and Optune Lua is turned on
  • Press the TTFields button. You will know that treatment is being delivered when the 3 blue indicators surrounding the button light up
  • As long as the device and TTFields are turned on, therapy is being delivered
  • Optune Lua records the amount of time that therapy is delivered per day
  • Your healthcare team will receive a monthly usage report to monitor your treatment goals
Warm feeling

What will I feel when using Optune Lua?

  • You may experience a warm feeling/sensation, which is normal

Can I exercise while using Optune Lua?

  • It's important that you keep the device and arrays from getting wet
  • More frequent array changes may be needed if you've performed a physical activity that causes you to sweat more

What should I do if I get my transducer arrays wet?

  • Getting the transducer arrays wet can cause the patches to come loose and interfere with contact to your skin. If this happens, the alarm may sound and the device may turn off. Any time the transducer arrays become wet or loosen, they should be changed
Warning if pregnant

Can I use Optune Lua if I'm pregnant?

  • Optune Lua was not tested in pregnant women. Do not use Optune Lua if you are pregnant, think you might be pregnant, or are trying to get pregnant

Can I talk on my mobile phone or use a microwave while using Optune Lua?

Car adapter warning

Can Optune Lua be charged in a car charger?

  • Using a car adapter is not recommended. Please only use those items that were provided to you by Novocure®. Optune Lua is portable and battery operated, but it is not designed to be plugged into a car charger
  • Remember, if you plan to be out for more than 1.5 hours, carry an extra battery or the power supply with you, in case the current battery runs out

X-ray, CT scan, or MRI guidelines for transducer arrays

Do I need to remove the transducer arrays for an x-ray, CT scan, or MRI?

  • For all x-rays, CT scans, and MRIs, the device should always be turned off and the arrays should be disconnected from the connection cable box just as you would do when taking a shower. The device should then be left outside of the procedure room
  • Whether or not you also need to remove the arrays depends on what type of test is being performed and on what part of your body. You should speak with your doctor if you are uncertain. If your doctor has questions, he or she can call nCompass at 1-855-281-9301
