Sunosi may also be used for other conditions as determined by your healthcare provider.

How does Sunosi work (mechanism of action)?

Sunosi helps you to feel more awake during the day. It may work by increasing the levels of norepinephrine and dopamine in the brain. These natural chemicals play a role in regulating the body’s sleep cycle. 

How is Sunosi supplied (dosage forms)?

Sunosi is available in the following dosage forms that are taken by mouth.

  • 75 mg oral tablets
  • 150 mg oral tablets

How should I store Sunosi?

Sunosi should be stored at room temperature, between 68 F to 77 F (20 C to 25 C). It can be exposed to temperatures between 59 F to 86 F (15 C to 30 C) for shorter periods of time, such as when transporting it. Store in a safe place, away from children and pets, like a locked cabinet. 

If you need to throw away Sunosi, bring it to a medicine take-back program at an authorized collection site, such as a pharmacy or police station. If no take-back program is available, mix it with a nontoxic and unattractive substance, such as dirt, cat litter, or used coffee grounds and place it in a container like a sealed plastic bag. Throw away the mixture in household trash.

What should I know about Sunosi before using it?

Do not take Sunosi unless it has been prescribed to you by a healthcare provider. Take it as prescribed.
