What is the purpose of this medication?

Erdafitinib is used to treat certain types of urothelial cancer (cancer of the bladder and other parts of the urinary tract) that have spread to nearby tissues or other parts of the body and have worsened during or after treatment with other chemotherapy medications. Erdafitinib belongs to a family of drugs known as kinase inhibitors. It works by preventing an aberrant protein from signaling cancer cells to proliferate.

What should I know about this medication’s storage and disposal?

Keep this medication in its original container, properly closed, and out of the reach of children. It should be stored at room temperature, away from excessive heat and moisture (not in the bathroom).

It is critical to keep all medicine out of children’s sight and access since many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are readily opened by young children. To keep small children safe from poisoning, always lock the safety caps and immediately store the medication in a safe location out of their sight and reach.

Unwanted drugs should be disposed of in a certain manner so that dogs, children, and other people cannot swallow them. You should not, however, dump this drug down the toilet. Instead, a medicine take-back programme is the best approach to dispose of your medicines. Learn about take-back programmes in your neighbourhood by speaking with your chemist or contacting your local garbage/recycling agency. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website ( for additional information.
