WARNING
RISK OF SERIOUS DEHYDRATION IN PEDIATRIC PATIENTS
- Trulance is contraindicated in patients less than 6 years of age; in nonclinical studies in young juvenile mice administration of a single oral dose of plecanatide caused deaths due to dehydration.
- Avoid use of Trulance in patients 6 years to less than 18 years of age.
- The safety and effectiveness of Trulance have not been established in patients less than 18 years of age.
Trulance can cause serious side effects, including:
- Diarrhea is the most common side effect of Trulance, and it can sometimes be severe.
- Diarrhea often begins within the first 4 weeks of Trulance treatment.
Stop taking Trulance and call your doctor if you develop severe diarrhea.
These are not all the possible side effects of Trulance.
Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What is the dosage for Trulance?
The recommended dosage of Trulance for the treatment of CIC and IBS-C is 3 mg taken orally once daily.

- Pour approximately 30 mL of room temperature water into the cup.
- Mix by gently swirling the tablet and water mixture for at least 10 seconds. The Trulance tablet will fall apart in the water.
