Welchol Delivers Efficacy Without Being Systemically Absorbed1
Welchol does not enter the bloodstream, so you can provide add-on efficacy without systemic absorption.

- Welchol binds to bile acids in the intestine without being metabolized by the liver and kidneys

- No dosage adjustment is required in patients with hepatic or mild to moderate renal impairment. Welchol has not been studied in severe renal impairment
Contraindications
Welchol is contraindicated in patients with:
- A history of bowel obstruction
- Serum TG concentrations >500 mg/dL
- A history of hypertriglyceridemia-induced pancreatitis
In T2DM studies
- Incidence of hypoglycemia was similar between the Welchol and placebo groups (3.0% vs 2.3%)1
- No incidence of severe hypoglycemia was reported1
- Welchol was not associated with weight gain1
Most common adverse reactions1

Welchol may increase triglyceride levels, especially in patients on a sulfonylurea- or insulin-based therapy. Periodic monitoring of lipid parameters including TG and non–HDL-C levels is recommended. The long-term effect of hypertriglyceridemia on the risk of coronary artery disease is uncertain.
