Considerations for Using Rybelsus (Semaglutide) in Patients with Ulcerative Colitis and Type 2 Diabetes

Rybelsus (oral semaglutide) can be used in patients with ulcerative colitis and type 2 diabetes, but requires careful monitoring for gastrointestinal side effects which may exacerbate ulcerative colitis symptoms.

Efficacy and Benefits of Semaglutide

Semaglutide is a GLP-1 receptor agonist with proven efficacy for type 2 diabetes management:

• Reduces HbA1c by approximately 1.1-1.5% and body weight by up to 5 kg 1
• Recommended for patients with type 2 diabetes, particularly those at high cardiovascular risk 2
• Demonstrated cardiovascular benefits in clinical trials, with reduced risk of major adverse cardiovascular events 2

Special Considerations for Ulcerative Colitis Patients

Gastrointestinal Effects

• GLP-1 receptor agonists commonly cause gastrointestinal side effects that may potentially worsen ulcerative colitis symptoms:
  • Nausea and vomiting (most common)
  • Diarrhea
  • Dyspepsia
  • Gastrointestinal reflux 2

Risk Mitigation Strategies

1. Start at low dose and titrate slowly:

   • Begin with 3 mg daily for 30 days
   • Increase to 7 mg daily for 30 days
   • Target maintenance dose of 14 mg daily as tolerated 3

2. Manage gastrointestinal side effects:

   • Reduce meal size to manage diarrhea
   • Limit alcohol and carbonated drinks to reduce reflux
   • Avoid high-fat diet to prevent constipation 2

3. Monitor disease activity:

   • Assess ulcerative colitis symptoms regularly
   • Consider temporary dose reduction or discontinuation if significant exacerbation occurs

Alternative Options

If gastrointestinal side effects are severe or worsen ulcerative colitis:

1. SGLT2 inhibitors (empagliflozin, canagliflozin, dapagliflozin):

   • Recommended for cardiovascular risk reduction
   • Lower risk of HF hospitalization
   • May have fewer gastrointestinal side effects 2

2. DPP4 inhibitors (sitagliptin, linagliptin):

   • Have neutral effect on heart failure risk
   • Generally well-tolerated with fewer gastrointestinal effects 2

Special Monitoring Considerations

• Renal function: Semaglutide is safe in moderate renal impairment (eGFR 30-59 mL/min/1.73m²) without dose adjustment 4
• Hydration status: Monitor closely as both ulcerative colitis and GI side effects can lead to dehydration
• Nutritional status: Assess regularly as both conditions can impact nutrition

Administration Guidelines

• Take on an empty stomach with no more than 4 ounces of plain water
• Wait at least 30 minutes before eating, drinking, or taking other oral medications
• Avoid taking with other medications that may irritate the GI tract

Red Flags for Discontinuation

• Severe exacerbation of ulcerative colitis symptoms
• Intractable nausea, vomiting, or diarrhea
• Signs of pancreatitis (contraindicated in patients with history of pancreatitis) 2
• Significant weight loss beyond therapeutic goals

Follow-up Protocol

• Assess gastrointestinal symptoms and ulcerative colitis disease activity at 2-4 weeks after initiation and after each dose increase
• Monitor HbA1c every 3 months
• Evaluate weight changes at each visit

By carefully implementing these strategies, Rybelsus can be used effectively in patients with both ulcerative colitis and type 2 diabetes, with close monitoring to ensure that gastrointestinal side effects do not exacerbate the underlying inflammatory bowel disease.
