Dulaglutide dosing & administration
Once-weekly GLP-1 receptor agonist Fc-fusion protein (Trulicity) that reduces HbA1c by 1.5–1.9%, promotes 3–4.6 kg weight loss, and demonstrated cardiovascular event reduction in the REWIND trial — available in convenient pre-filled autoinjector with no reconstitution required

Dosing
How much do I take?
Subcutaneous: A small injection into the fatty layer just under the skin — the same way insulin is given.
Bioavailability High — most of the dose reaches your bloodstream, just more gradually than an IV.
Titration schedule
0.75 mg
Frequency
Once weekly
Duration
4 weeks before increasing
FDA-approved starting dose for type 2 diabetes. Injected under the skin of the abdomen, thigh, or upper arm on the same day each week [4].
1.5 mg
Frequency
Once weekly
Duration
Ongoing
3.0–4.5 mg
Frequency
Once weekly
Duration
Ongoing
FDA-approved higher doses. In the AWARD-11 trial, stepping up to 3.0 mg then 4.5 mg gave added blood-sugar and weight benefits; 4.5 mg is the maximum dose [1].
Timing
Best time to take
Administer Dulaglutide at the same time each day (or on the same day each week for weekly injections). Many users prefer morning or evening administration. Pick a time you'll remember consistently.
With food?
Dulaglutide injections can be given regardless of meal timing. However, if GI effects occur, administering on an empty stomach or with a light meal may help reduce discomfort.
If stacking
Dulaglutide should be used as directed by your healthcare provider. If combining with other medications or supplements, discuss potential interactions with your provider. Avoid combining with compounds that have overlapping mechanisms unless specifically guided by a medical professional.
Adjusting your dose
Increase if
- You've tolerated the current dose for the recommended period without significant side effects
- Therapeutic goals haven't been met at the current dose level
- Your healthcare provider recommends dose escalation based on your response
- Lab work or clinical assessments support a higher dose
Decrease if
- Side effects are bothersome or impacting daily life despite management strategies
- You experience any signs of an adverse reaction
- Lab results indicate the need for dose reduction
- Your healthcare provider recommends a lower dose based on your response
Signs of right dose
- Therapeutic goals being met with minimal side effects
- Stable and consistent response to treatment
- Lab values or clinical markers trending in the right direction
- Good tolerance with manageable or absent side effects
Administration
How do I use it?
Reconstitution
What you need
Injection
Route
Subcutaneous injection (into the fatty tissue just under the skin)—allows for consistent absorption and can be self-administered at home after proper training
Best sites
Storage
Before reconstitution
Store Dulaglutide in the refrigerator at 36-46°F (2-8°C) in its original packaging. Protect from light and moisture. Do not freeze. Check the expiration date before use. Some formulations may be stored at room temperature for limited periods—check your specific product labeling.
After reconstitution
Once reconstituted, Dulaglutide should be kept refrigerated at 36-46°F (2-8°C) and used within the timeframe specified on your product labeling (typically 14-28 days). Label the vial with the reconstitution date. Do not use if the solution appears cloudy, discolored, or contains particles.
Signs of degradation — discard the vial

Site: Subcutaneous injection—rotate sites if applicable
Maintain a consistent schedule for optimal results with Dulaglutide. Set reminders if needed. If you miss a dose, follow your healthcare provider's instructions—do not double up on doses to compensate.
Safety
Is it safe?
Side effects
Commonly reported: Nausea, Diarrhea and abdominal pain, Vomiting, Decreased appetite
Less common: Injection site reactions and fatigue
Stop and seek help if
- Severe or worsening side effects that don't improve with dose adjustment or supportive care
- Signs of an allergic reaction—rash, hives, swelling, or difficulty breathing
- Your healthcare provider recommends discontinuation based on your clinical response
- Development of any new medical condition that may be contraindicated with Dulaglutide
- Pregnancy or planning to become pregnant (unless specifically approved for use during pregnancy)
- Abnormal lab results or clinical markers that suggest adverse effects
Dulaglutide should only be started, adjusted, or discontinued under medical supervision. This information is for educational purposes only and does not replace professional medical advice. Never stop a prescribed treatment without consulting your healthcare provider first, as abrupt discontinuation may have consequences.
Flagged pairings
- Other GLP-1 receptor agonists (liraglutide, semaglutide, exenatide) — redundant mechanism with increased adverse effects and no additional benefit — Use with caution—discuss with your healthcare provider.
- DPP-4 inhibitors — overlapping incretin pathway mechanism without additional glycemic benefit — Use with caution—discuss with your healthcare provider.
- Sulfonylureas or insulin at full dose — increased hypoglycemia risk; dose reduction of insulin secretagogues required when initiating dulaglutide — Use with caution—discuss with your healthcare provider.
