Boxed warning
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 [see Contraindications (4) , Use in Specific Populations (8.4) ] . Avoid use of TRULANCE in patients 6 years to less than 18 years of age [see Warnings and Precautions (5.1) , Use in Specific Populations (8.4) ] . The safety and effectiveness of TRULANCE have not been established in patients less than 18 years of age [see Use in Specific Populations (8.4) ] .

Preparation and administration
Preparation and Administration Instructions Take TRULANCE with or without food [see Clinical Pharmacology ] . If a dose is missed, skip the missed dose and take the next dose at the regular time. Do not take two doses at the same time. Swallow a tablet whole for each dose. For adult patients with swallowing difficulties, TRULANCE tablets can be crushed and administered orally either in applesauce or with water or administered with water via a nasogastric or gastric feeding tube.
Mixing TRULANCE crushed tablets in other soft foods or in other liquids has not been tested. Oral Administration in Applesauce: In a clean container, crush the TRULANCE tablet to a powder and mix with 1 teaspoonful of room temperature applesauce. Consume the entire tablet-applesauce mixture immediately. Do not store the mixture for later use.
Oral Administration in Water: Place the TRULANCE tablet in a clean cup. 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. Swallow the entire contents of the tablet-water mixture immediately.
If any portion of the tablet is left in the cup, add another 30 mL of water to the cup, swirl for at least 10 seconds, and swallow immediately. Do not store the tablet-water mixture for later use. Administration with Water via a Nasogastric or Gastric Feeding Tube: Place the TRULANCE tablet in a clean cup with 30 mL of room temperature water.
Mix by gently swirling the tablet and water mixture for at least 15 seconds. The TRULANCE tablet will fall apart in the water. Flush the nasogastric or gastric feeding tube with 30 mL of water using a catheter tip syringe. Draw up the mixture using the syringe and immediately administer via the nasogastric or gastric feeding tube.
Do not reserve for future use. If any portion of the tablet is left in the cup, add another 30 mL of water to the cup, swirl for at least 15 seconds, and using the same syringe, administer via the nasogastric or gastric feeding tube. Using the same or a fresh syringe, flush the nasogastric or gastric feeding tube with at least 10 mL of water.
Contraindications
4 CONTRAINDICATIONS TRULANCE is contraindicated in: Patients less than 6 years of age due to the risk of serious dehydration [see Warnings and Precautions (5.1) , Use in Specific Populations (8.4) ] . Patients with known or suspected mechanical gastrointestinal obstruction. Patients less than 6 years of age due to the risk of serious dehydration. ( 4 , 5.1 , 8.4 ) Patients with known or suspected mechanical gastrointestinal obstruction. ( 4 )
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary Plecanatide and its active metabolite are negligibly absorbed systemically following oral administration [see Clinical Pharmacology (12.3) ] and maternal use is not expected to result in fetal exposure to the drug. The available data on TRULANCE use in pregnant women are not sufficient to inform any drug-associated risks for major birth defects and miscarriage. In animal developmental studies, no effects on embryo-fetal development were observed with oral administration of plecanatide in mice and rabbits during organogenesis at doses much higher than the recommended human dosage.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the United States general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data Pregnant mice and rabbits were administered plecanatide during the period of organogenesis. There was no evidence of harm to embryo-fetal development at oral doses up to 800 mg/kg/day in mice and 250 mg/kg/day in rabbits.
Oral administration of up to 600 mg/kg/day in mice during organogenesis through lactation produced no developmental abnormalities or effects on growth, learning and memory, or fertility in the offspring through maturation. The maximum recommended human dose is approximately 0.05 mg/kg/day, based on a 60-kg body weight. Limited systemic exposure to plecanatide was achieved in animals during organogenesis (area under the plasma concentration-time curve (AUC t ) = 449 ng ● h/mL in rabbits given 250 mg/kg/day). Plecanatide and its active metabolite are not measurable in human plasma following administration of the recommended clinical dosage.
Therefore, animal and human doses should not be compared directly for evaluating relative exposure.
