Yes, Trulicity Is Once Weekly
Trulicity (dulaglutide) is administered as a subcutaneous injection once every week. Patients typically inject it on the same day each week, with or without food, using a prefilled single-dose pen. The recommended starting dose is 0.75 mg weekly, which can increase to 1.5 mg, 3 mg, or 4.5 mg based on response and tolerance.
How to Use It Correctly
Inject into the abdomen, thigh, or upper arm. Rotate sites weekly to avoid irritation. If a dose is missed, take it within 3 days; otherwise, skip and resume the next scheduled day. Storage requires refrigeration until first use, then room temperature for up to 21 days.
What If You Miss a Dose?
Missing doses reduces blood sugar control. Resume on the next weekly schedule without doubling up, as that risks low blood sugar (hypoglycemia).
Common Side Effects Patients Report
Nausea (most frequent, often improves over time), vomiting, diarrhea, abdominal pain, and injection-site reactions. Thyroid tumors seen in rodents; human risk unclear—avoid if family history of medullary thyroid carcinoma.
How It Compares to Other GLP-1 Drugs
| Drug | Dosing | Key Difference |
|------|--------|----------------|
| Trulicity | Weekly | Prefilled pen, no dose mixing |
| Ozempic (semaglutide) | Weekly | Similar efficacy; also used for weight loss |
| Victoza (liraglutide) | Daily | More frequent dosing |
| Mounjaro (tirzepatide) | Weekly | Dual GLP-1/GIP action; often stronger A1C reduction |
Trulicity lowers A1C by 0.7-1.6% and supports 5-15 lbs weight loss over 6-12 months in trials.
Who Makes It and Cost Factors
Eli Lilly manufactures Trulicity. List price is about $1,000/month without insurance; patient assistance or coupons can drop it to $25/month for eligible users.
