Administration ( 2.1 ) : Alteration of analgesic dosing regimen prior to initiating SYMPROIC is not required Patients receiving opioids for less than 4 weeks may be less responsive to SYMPROIC Discontinue SYMPROIC if treatment with the opioid pain medication is also discontinued Dosage ( 2.2 ) : In adults, the recommended dosage is 0.2 mg once daily with or without food 2.1 Administration Alteration of analgesic dosing regimen prior to initiating SYMPROIC is not required. Patients receiving opioids for less than 4 weeks may be less responsive to SYMPROIC [see Clinical Studies (14) ] . Discontinue SYMPROIC if treatment with the opioid pain medication is also discontinued. 2.2 Adult Dosage The recommended dosage of SYMPROIC is 0.2 mg orally once daily with or without food.

Serious and important adverse reactions described elsewhere in labeling include: Gastrointestinal perforation [see Warnings and Precautions (5.1) ] Opioid withdrawal [see Warnings and Precautions (5.2) ] Most common adverse reactions (≥2%) are: abdominal pain, diarrhea, nausea and gastroenteritis ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact BioDelivery Sciences International, Inc. at 1-800-469-0261 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to SYMPROIC in 1163 patients in clinical trials, including 487 patients with exposures greater than six months and 203 patients with exposures of 12 months. The following safety data are derived from three double-blind, placebo-controlled trials in patients with OIC and chronic non-cancer pain: two 12-week studies (Studies 1 and 2) and one 52-week study (Study 3) [see Clinical Studies (14) ]. In Studies 1 and 2, patients on laxatives were required to discontinue their use prior to study enrollment. All patients were restricted to bisacodyl rescue treatment during the study. In Study 3,…

SYMPROIC is contraindicated in: Patients with known or suspected gastrointestinal obstruction and patients at increased risk of recurrent obstruction, due to the potential for gastrointestinal perforation [see Warnings and Precautions (5.1) ]. Patients with a history of a hypersensitivity reaction to naldemedine. Reactions have included bronchospasm and rash [see Adverse Reactions (6.1) ] . Patients with known or suspected gastrointestinal obstruction or at increased risk of recurrent obstruction ( 4 , 5.1 ) Patients with a history of a hypersensitivity reaction to naldemedine ( 6.1 )

Single doses of naldemedine up to 100 mg (500 times the recommended dose) and multiple doses of up to 30 mg (150 times the recommended dose) for 10 days have been administered to healthy subjects in clinical studies. Dose-dependent increases in gastrointestinal-related adverse reactions, including abdominal pain, diarrhea, and nausea, were observed. Single doses of naldemedine up to 3 mg (15 times the recommended dose) and multiple doses of 0.4 mg (twice the recommended dose) for 28 days have been administered to patients with OIC in clinical studies. Dose-dependent increases in gastrointestinal-related adverse reactions, including abdominal pain, diarrhea, nausea, and vomiting, were observed. Also, chills, hyperhidrosis, and dizziness were reported more frequently at 1 and 3 mg doses and hyperhidrosis at the 0.4 mg dose. No antidote for naldemedine is known. Hemodialysis is not an effective means to remove naldemedine from the blood [see Clinical Pharmacology (12.3) ] .

Table 3 includes drugs with clinically important drug interactions with SYMPROIC and instructions for preventing or managing the interaction. Table 3: Clinically Relevant Interactions Affecting Naldemedine When Co-Administered with Other Drugs Strong CYP3A Inducers (e.g., rifampin, carbamazepine, phenytoin, St. John's Wort) Clinical Impact Significant decrease in plasma naldemedine concentrations, which may reduce efficacy [see Clinical Pharmacology (12.3) ] Intervention Avoid use of SYMPROIC with strong CYP3A inducers. Other Opioid Antagonists Clinical Impact Potential for additive effect of opioid receptor antagonism and increased risk of opioid withdrawal. Intervention Avoid use of SYMPROIC with another opioid antagonist. Moderate (e.g., fluconazole, atazanavir, aprepitant, diltiazem, erythromycin) and Strong (e.g., itraconazole, ketoconazole, clarithromycin, ritonavir, saquinavir) CYP3A Inhibitors Clinical Impact Increase in plasma naldemedine concentrations [see Clinical Pharmacology (12.3) ] Intervention Monitor for potential naldemedine-related adverse reactions [see Adverse Reactions (6.1) ] . P-glycoprotein (P-gp) Inhibitors (e.g., amiodarone, captopril, cyclosporine, quercetin, quinidine, verapamil) Clinical Impact Increase in plasma naldemedine concentrations [see Clinical Pharmacology (12.3) ] Intervention Monitor for potential naldemedine-related adverse reactions [see Adverse Reactions (6.1) ] . Strong CYP3A inducers (e.g., rifampin) : Decreased naldemedine concentrations; avoid concomitant use ( 7 ) Other opioid antagonists : Potential for additive effect and increased risk of opioid withdrawal; avoid concomitant use ( 7 ) Moderate (e.g., fluconazole) and strong (e.g., itraconazole) CYP3A4 inhibitors : Increased naldemedine concentrations; monitor for adverse reactions ( 7 ) P-gp inhibitors (e.g., cyclosporine) : Monitor for adverse reactions ( 7 )
