Safety of VIBERZI

The most common side effects of VIBERZI include:

  • Constipation
  • Nausea
  • Abdominal pain

Stop taking VIBERZI and call your doctor if you have constipation that lasts more than 4 days. These are not all the possible side effects of VIBERZI. Call your doctor for medical advice about side effects.

VIBERZI can cause serious side effects, including:

  • A spasm in a muscle of the digestive system (called the sphincter of Oddi), which may cause new or worsening abdominal pain. Your risk of having a spasm is increased if you do not have a gallbladder. This spasm usually happens within the first week of treatment and usually goes away when treatment is stopped.

Stop taking VIBERZI and call your doctor if you have new or worsening stomach‑area (abdomen) pain or pain in the upper right side of your stomach‑area (abdomen) that may move to your back or shoulder, with or without nausea and vomiting.
