warnings and cautions
5 WARNINGS AND PRECAUTIONS Hypertriglyceridemia and Pancreatitis: Colesevelam hydrochoride can increase TG. Hypertriglyceridemia can cause acute pancreatitis. Monitor lipids, including TG . Instruct patients to discontinue colesevelam hydrochoride and seek prompt medical attention if the symptoms of acute pancreatitis occur ( 5.1 ). Gastrointestinal Obstruction: Cases of bowel obstruction have occurred. Colesevelam hydrochoride is not recommended in patients with gastroparesis, other gastrointestinal motility disorders, and in those who have had major gastrointestinal tract surgery and who may be at risk for bowel obstruction ( 5.2 ). Vitamin K or Fat-Soluble Vitamin Deficiencies: Colesevelam hydrochoride may decrease absorption of fat-soluble vitamins. Patients with a susceptibility to deficiencies of vitamin K (e.g., patients on warfarin, patients with malabsorption syndromes) or other fat-soluble vitamins may be at increased risk. Patients on oral vitamin supplementation should take their vitamins at least 4 hours prior to colesevelam hydrochoride ( 5.3 ). Drug Interactions: Due to the potential for decreased absorption of other drugs that have not been tested for interaction, consider administering at least 4 hours prior to colesevelam hydrochoride ( 5.4 , 7 , 12.3 ). Risks in Patients with Phenylketonuria (PKU) : Phenylalanine can be harmful to patients with phenylketonuria (PKU). Colesevelam hydrochloride for oral suspension contains 33.6 mg phenylalanine per 3.75 gram packet ( 5.5 , 11 ). 5.1 Hypertriglyceridemia and Pancreatitis Colesevelam hydrochloride, like other bile acid sequestrants, can increase serum TG concentrations. Hypertriglyceridemia can cause acute pancreatitis. Colesevelam hydrochloride had effects on serum TG (median increase 5% compared to placebo) in trials of patients with primary hyperlipidemia. Obtain lipid parameters, including TG levels before starting colesevelam hydrochloride and periodically thereafter. Colesevelam hydrochloride is contraindicated in patients with TG levels greater than 500 mg/dL or patients with a history of hypertriglyceridemia-induced pancreatitis [see Contraindications ( 4 )] . Patients with TG levels greater than 300 mg/dL could have greater increases in serum TG levels with colesevelam hydrochloride and may require additional TG monitoring. Instruct patients to discontinue colesevelam hydrochloride...

adverse reactions
6 ADVERSE REACTIONS The following important adverse reactions are described below and elsewhere in the labeling: Hypertriglyceridemia and Pancreatitis [see Warnings and Precautions ( 5.1 )] Gastrointestinal Obstruction [see Warnings and Precautions ( 5.2 )] Vitamin K or Fat-Soluble Vitamin Deficiencies [see Warnings and Precautions ( 5.3 )] In clinical trials, the most common (incidence ≥2% and greater than placebo) adverse reactions with Colesevelam hydrochloride included constipation, dyspepsia, and nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Ascend Laboratories, LLC at 1-877-ASC-RX01 (877-272-7901) or FDA at 1-800-FDA-1088 or www.fda.gov /medwatch . 6.1 Clinical Studies Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in clinical studies of another drug and may not reflect the rates observed in practice. Primary Hyperlipidemia In 7 double-blind, placebo-controlled, clinical trials, 807 patients with primary hyperlipidemia (age range 18-86 years, 50% women, 90% Caucasians, 7% Blacks, 2% Hispanics, 1% Asians) and elevated LDL-C were treated with colesevelam hydrochloride 1.5 g/day to 4.5 g/day from 4 to 24 weeks (total exposure 199 patient-years).
