Administer orally as a powder mixed with water or other liquids
Assess for allergies to cholestyramine
Administer other medications 1 hour before or 4-6 hours after cholestyramine
Encourage adequate fluid intake to prevent constipation
Monitor lipid levels to assess treatment effectiveness

Cimetidine

Histamine H2 receptor antagonist used to treat ulcers and GERD
Blocks H2 receptors in the stomach, reducing gastric acid secretion
Administer orally or IV
Assess for hypersensitivity to cimetidine
Monitor for reduced gastric acid secretion and relief from heartburn or ulcer symptoms
Educate patients to take the medication with meals or at bedtime
Be aware of potential drug interactions, especially with medications metabolized by the liver
