What is Sotorasib?
Sotorasib is used in adults to treat non-small cell lung cancer who have already been treated with at least one other cancer medicine.
Sotorasib is given when the cancer has progressed or has spread to other parts of the body or when surgery is not an option.
Your doctor will make sure you have the correct tumor type to be treated with sotorasib.
Sotorasib may also be used for purposes not listed in this medication guide.
Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from light, excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
What special dietary instructions should I follow?
Unless your doctor tells you otherwise, continue your normal diet.
What should I avoid while using Sotorasib?
