You may experience side effects related to your infusions

As with any intravenous (IV) infusion, there is potential for infusion-related reactions. You may be more likely to experience an infusion-related reaction during your first few infusions. The chances of experiencing an infusion reaction should lessen as your body gets used to treatment.

Let your healthcare professional know right away if you experience any symptoms such as chills or shaking, nausea, fever, rapid heartbeat, headache, or vomiting.

To reduce the occurrence of an infusion reaction, your doctor may prescribe medications to take on the day you start treatment with POTELIGEO.

Skin-related reactions are possible

  • Rash is a possible side effect of POTELIGEO
    - If you experience a reaction, it doesn’t necessarily mean POTELIGEO isn’t working
    - Your doctor may call this drug eruption
  • Rash may occur at any time, and the appearance and location of the rash may vary
  • In the POTELIGEO clinical trial, most cases of rash (82%) were mild or moderate
  • Tell your doctor if you think you may be experiencing a rash. They may prescribe a topical medicine such as a corticosteroid and will determine if it’s necessary to pause or stop treatment with POTELIGEO
