How to Administer Trulicity (Dulaglutide)
Trulicity is administered as a subcutaneous injection once weekly at any time of day, with or without food, using a pre-filled single-dose pen injected into the abdomen, thigh, or upper arm. 1
Dosing Regimens
Adult Patients
- Starting dose: 0.75 mg subcutaneously once weekly 1
- Standard maintenance dose: 1.5 mg once weekly for additional glycemic control 1
- Dose escalation: If further glycemic control is needed, increase in 1.5 mg increments after at least 4 weeks on the current dose 1
- Maximum dose: 4.5 mg subcutaneously once weekly 1
Pediatric Patients (≥10 years)
- Starting dose: 0.75 mg subcutaneously once weekly 1
- Maximum dose: 1.5 mg once weekly after at least 4 weeks on the 0.75 mg dose 1
Administration Technique
Injection Sites and Rotation
- Approved injection sites: Abdomen, thigh, or upper arm 1
- Site rotation: Rotate injection sites with each weekly dose to minimize local reactions 1
- When used with insulin: Administer as separate injections and never mix; injections may be given in the same body region but should not be adjacent to each other 1
Pre-Administration Inspection
- Visual inspection required: Solution should appear clear and colorless 1
- Do not use if: Particulate matter or discoloration is present 1
Timing Flexibility
- Administration schedule: Once weekly at any time of day, with or without food 1
- Day changes permitted: The weekly administration day can be changed if the last dose was administered 3 or more days before the new scheduled day 1
Missed Dose Management
If a dose is missed, administer as soon as possible only if there are at least 3 days (72 hours) until the next scheduled dose. 1
- Less than 3 days remaining: Skip the missed dose and administer the next dose on the regularly scheduled day 1
- After addressing missed dose: Resume the regular once-weekly dosing schedule 1
Renal Dosing Considerations
- No dose adjustment required for any level of renal impairment, including end-stage renal disease 2
- Monitoring recommendation: Monitor eGFR in patients with chronic kidney disease who report severe gastrointestinal adverse reactions 2
- Contraindication note: Some older guidelines suggested avoiding use in severe renal impairment/ESRD, but current FDA labeling does not require dose adjustment 2
Perioperative Management
Timing of Discontinuation
- For elective procedures: Consider stopping 1 week before surgery due to the weekly dosing schedule and prolonged half-life of 4.5-4.7 days 2
- Rationale: GLP-1 receptor agonists delay gastric emptying, potentially increasing aspiration risk during anesthesia 2
- Individual factors to consider: Drug characteristics, patient profile, procedure type, and anaesthetic technique must all be weighed against the adverse impact of drug cessation 2
Patient Education Requirements
- Training mandatory: Patients and caregivers must be trained on proper injection technique prior to initiation 1
- Thyroid monitoring awareness: Counsel patients about potential thyroid C-cell tumor risk and symptoms (neck mass, dysphagia, dyspnea, persistent hoarseness), though routine calcitonin monitoring is of uncertain value 1
- Gastrointestinal effects: Inform patients that nausea, vomiting, and diarrhea are the most common adverse events 3
Important Clinical Caveats
- Contraindications: Personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 1
- Not studied in: Patients with history of pancreatitis or severe gastroparesis 1
- Hypersensitivity reactions: Rare cases of cutaneous hypersensitivity and anaphylactic reactions have been reported 1, 4
