Soliqua Titration Protocol
Start with 15 units once daily (10-20 units range for insulin-naïve patients), inject within 1 hour before breakfast, and increase by 2 units every 3 days until fasting plasma glucose reaches 90-150 mg/dL without hypoglycemia. 1, 2
Starting Dose Selection
- For insulin-naïve patients: Begin with 10-20 units per day (or 0.1-0.2 units/kg per day) 1
- For patients already on basal insulin: The dose depends on their current insulin requirement, as Soliqua is available in two pen formulations:
- Pen 1: Allows titration up to 40 units of insulin glargine daily (with lixisenatide up to 20 µg)
- Pen 2: Allows titration up to 60 units of insulin glargine daily (with lixisenatide up to 20 µg) 3
Titration Schedule
Increase by 2 units every 3 days until you reach target fasting glucose without hypoglycemia 1, 2. This gradual uptitration of the GLP-1 component (lixisenatide) minimizes gastrointestinal side effects compared to starting lixisenatide alone 3.
Target Goals
- Fasting plasma glucose: 90-150 mg/dL 2
- Monitor fasting blood glucose levels regularly during titration 1
Adjustment Rules
- If 50% of fasting glucose values remain above target: Continue increasing by 2 units every 3 days 2
- If fasting glucose falls below 80 mg/dL more than twice weekly: Decrease dose by 2 units 2
- If hypoglycemia occurs: Reduce dose by 10-20% and reassess the cause 1
Timing of Administration
Inject once daily within 1 hour before breakfast for optimal glycemic control. 4 While Soliqua can be administered before any meal, pre-breakfast injection resulted in the greatest HbA1c reduction (1.57%) compared to pre-lunch (1.27%) or pre-dinner (1.42%) in real-world data 4. Pre-breakfast timing also achieved the highest proportion of patients reaching HbA1c <7% (33.7% vs 19-25.6% for other times) 4.
Monitoring During Titration
- Assess fasting finger-stick glucose values over each week to guide dose adjustments 2
- Evaluate adequacy of insulin dose at every visit 1
- Watch for signs of overbasalization: elevated bedtime-to-morning glucose differential, hypoglycemia, or high glucose variability 1
Critical Pitfalls to Avoid
- Do not delay dose adjustments when glucose targets are not met—this leads to therapeutic inertia 1
- Never continue the same dose if hypoglycemia occurs—reduce by 10-20% immediately 1
- Do not increase dose if hypoglycemic episodes are present—always check for hypoglycemia before escalating 2
- Ensure proper injection technique and timing education to maximize effectiveness 2
When Soliqua Reaches Maximum Dose
If blood glucose remains elevated after optimizing Soliqua to maximum dose (40 or 60 units depending on pen), consider adding prandial insulin at the largest meal or other non-insulin agents 2. The combination provides complementary effects: insulin glargine targets fasting hyperglycemia while lixisenatide addresses postprandial glucose excursions 3, 5.
Expected Outcomes
Clinical trials demonstrate HbA1c reductions of approximately 1.1% with Soliqua compared to 0.6% with basal insulin alone, with 55% of patients achieving HbA1c <7% 5. Body weight typically decreases by 0.7-2.3 kg, and gastrointestinal side effects are minimal due to gradual lixisenatide titration 3, 4, 5.
