๐ก Key Considerations
- โMealtime insulin must be reduced by 50% when initiating pramlintide to prevent severe hypoglycemia (FDA boxed warning)
- โMust be administered as a separate injection from insulin; never mix in the same syringe
- โTitrate dose gradually over weeks; do not increase if significant nausea persists

Before You Begin
Review safety warnings and contraindications before starting any protocol.
FDA-Approved Dosing#
Pramlintide (Symlin) is FDA-approved as an adjunct to mealtime insulin in patients with type 1 or type 2 diabetes who have not achieved adequate glycemic control. Dosing differs between type 1 and type 2 diabetes.
Type 1 Diabetes Dosing#
| Phase | Dose | Duration |
|---|---|---|
| Starting dose | 15 mcg before meals | At least 3 days |
| Step 2 | 30 mcg before meals | At least 3 days |
| Step 3 | 45 mcg before meals | At least 3 days |
| Maintenance | 60 mcg before meals | Ongoing |
Titrate upward only if no significant nausea for at least 3 days at the current dose. Reduce the dose if persistent nausea occurs. Reduce back to 30 mcg or discontinue if 30 mcg is not tolerated.
Type 2 Diabetes Dosing#
| Phase | Dose | Duration |
|---|---|---|
| Starting dose | 60 mcg before meals | 3-7 days |
| Maintenance | 120 mcg before meals | Ongoing |
Critical Insulin Dose Adjustment#
Mealtime insulin must be reduced by 50% when starting pramlintide. This is a mandatory safety requirement to prevent severe hypoglycemia. The FDA boxed warning specifically addresses the risk of insulin-induced severe hypoglycemia when pramlintide is added to insulin therapy.
After pramlintide titration is complete and the patient is on a stable dose, mealtime insulin can be re-titrated upward as needed based on blood glucose monitoring.
Administration Guidelines#
- Inject subcutaneously immediately before each major meal (containing 250 calories or 30 grams of carbohydrate)
- Never mix pramlintide with insulin in the same syringe; they are incompatible
- Inject at a site distinct from the concurrent insulin injection
- If a meal is skipped, skip the pramlintide dose
- Rotate injection sites within the abdomen or thigh
SymlinPen Devices#
Two pen devices are available:
- SymlinPen 60: Delivers 15, 30, 45, or 60 mcg doses (for type 1 diabetes)
- SymlinPen 120: Delivers 60 or 120 mcg doses (for type 2 diabetes)
Dosing Context#
