Diabetes Medication Management in Comfort Care
For patients with type 2 diabetes transitioned to comfort care, discontinuation of all diabetes medications is a reasonable approach, particularly in actively dying patients who are unlikely to have oral intake; however, for patients with type 1 diabetes, a small amount of basal insulin should be maintained to prevent acute hyperglycemic complications and symptom burden. 1
Clinical Decision Framework
The approach to diabetes medications in comfort care depends critically on three patient categories:
1. Stable Comfort Care Patient
- Continue the previous diabetes regimen with modifications 2, 1, 3
- Primary goals:
- Prevent hypoglycemia (most important)
- Prevent symptomatic hyperglycemia and dehydration
- Allow glucose values in the upper target range
- Simplify the regimen: Consider oral agents first-line, followed by basal insulin only (without rapid-acting insulin) 2
- Reduce monitoring burden: Decrease finger-stick frequency; A1C monitoring has no role 2, 3
- Agents causing GI symptoms (nausea) or weight loss should be avoided 2, 1
2. Patient with Organ Failure
- Type 1 diabetes: Reduce insulin doses as oral intake decreases, but never stop insulin completely 2, 1, 3
- Type 2 diabetes: Reduce or discontinue agents that cause hypoglycemia 2
- Preventing hypoglycemia is paramount—allow glucose values at the upper end of target range 2, 3
- Focus on preventing dehydration
3. Actively Dying Patient
- Type 2 diabetes: Discontinue all diabetes medications—this is the most reasonable approach as patients have no oral intake 2, 1, 3, 4, 2
- Type 1 diabetes: Maintain a small amount of basal insulin to prevent diabetic ketoacidosis and acute hyperglycemic complications that would cause additional symptom burden 2, 1, 3
- The goal is comfort—avoid interventions causing pain or discomfort (injections, finger sticks) 5
Key Principles for All Comfort Care Patients
Primary outcomes to prioritize:
- Overall comfort and symptom prevention (pain, hypoglycemia, symptomatic hyperglycemia, dehydration) 2
- Preservation of quality of life and dignity 2
- Avoid distressing symptoms 2
What to discontinue beyond diabetes medications (per general comfort care guidelines):
- All non-comfort medications 6
- Blood work 6
- Parenteral nutrition and enteral tube feeding 6
- Antibiotics (unless for symptom control) 6
Critical Pitfalls to Avoid
Never completely stop insulin in type 1 diabetes patients—even dying patients need minimal basal insulin to prevent DKA, which causes severe discomfort 2, 1, 3
Don't maintain tight glycemic control—this contradicts comfort care goals and increases hypoglycemia risk 2
Avoid agents with high hypoglycemia risk (sulfonylureas, meglitinides) in any comfort care patient with inconsistent eating 5
Don't continue medications without clear symptom benefit—if a medication doesn't improve comfort, discontinue it 5
Practical Implementation
Involve the patient/family in shared decision-making about the medication plan, ensuring it aligns with goals of care and is convenient for caregivers 2. The most recent ADA guidelines (2025) emphasize that treatment interventions must be mindful of quality of life and that patients have the right to refuse testing and treatment 1.
For type 2 diabetes patients actively dying: The evidence consistently supports complete medication discontinuation as the default approach, as these patients typically have no oral intake and medications provide no comfort benefit 2, 1, 3, 4, 2.
For type 1 diabetes patients: While there is "no consensus" per guidelines, the consistent recommendation across all recent ADA standards is to maintain minimal basal insulin to prevent acute complications that would worsen symptom burden 2, 1, 3.
