Is it safe to combine 3mg with 1.5mg of Trulicity (dulaglutide) at one time?

Safety of Combining Trulicity (Dulaglutide) Doses

It is not safe or recommended to combine a 3mg dose with a 1.5mg dose of Trulicity (dulaglutide) at one time.

Proper Dulaglutide Dosing

• Dulaglutide (Trulicity) is a once-weekly GLP-1 receptor agonist with specific recommended dosing protocols that should be strictly followed 1
• The standard dosing of dulaglutide starts at 0.75 mg/0.5 mL subcutaneously once weekly, which can be increased as needed for glycemic control, but only according to approved dosing schedules 2
• Combining different doses (such as 3mg with 1.5mg) would result in a total dose of 4.5mg, which exceeds the maximum recommended dose and has not been studied for safety 3

Risks of Exceeding Recommended Doses

• Exceeding the recommended dose of dulaglutide could increase the risk of adverse effects, particularly gastrointestinal side effects such as nausea (15-20%), diarrhea (6-17%), and vomiting (3-4%) 4
• There is a documented risk of acute pancreatitis with dulaglutide, which could potentially be exacerbated by exceeding recommended doses 2
• Higher doses of GLP-1 receptor agonists are associated with increased incidence of gastrointestinal adverse events, which could affect medication adherence and patient quality of life 4

Proper Medication Administration

• Medications should be administered according to their FDA-approved dosing guidelines to ensure safety and efficacy 1
• Mixing insulin formulations has specific guidelines, but these do not apply to GLP-1 receptor agonists like dulaglutide, which should be administered as prescribed 1
• No medication should be mixed or combined unless specifically approved by the prescribing physician 1

Alternative Approaches

• If current treatment with dulaglutide is not providing adequate glycemic control, discuss with your healthcare provider about:
  • Adjusting to an appropriate single dose within the approved range 3
  • Adding or adjusting other antihyperglycemic medications 1
  • Considering alternative GLP-1 receptor agonists if dulaglutide is not effective at maximum approved doses 1

Important Safety Considerations

• Dulaglutide has been studied extensively in clinical trials at specific doses, but combining different doses in a single administration has not been evaluated for safety or efficacy 5
• Patients with kidney disease require careful monitoring when using dulaglutide, but the medication does not typically require dose adjustment based on renal function 5
• Always consult with your healthcare provider before making any changes to your medication regimen 1
