Dulaglutide

A weekly GLP-1 medicine approved for type 2 diabetes and lower heart-event risk.

GLP-1 / GIP / glucagon agonists · GLP-1 receptor agonist · Evidence: Approved drug.

What Dulaglutide does

Dulaglutide is a weekly GLP-1 medicine for type 2 diabetes. It is a GLP-1 and antibody-fragment fusion protein. Trials support blood-sugar control and fewer major heart events in adults with diabetes. It is not approved for weight management. Stomach upset is common, and dehydration, pancreatitis and eye complications need attention.

  • Trulicity is approved for type 2 diabetes from age 10, and to lower major heart-event risk in some adults with diabetes. (Drug label)
  • In a trial, the 1.5 mg dose lowered the long-term blood sugar score by 1.51 points, versus 0.46 on placebo. (Studied in a trial)
  • In a large heart trial, 12.0% of people on dulaglutide had a major heart event, versus 13.4% in the comparison group. (Studied in a trial)
  • Weight also fell in diabetes trials, though it is not approved for weight loss. (Studied in a trial)

How to store Dulaglutide

Comes as: Ready-made single-use pens: 0.75, 1.5, 3 or 4.5 mg in 0.5 mL.

Mixed with: None; do not dilute, split, refill or transfer the prefilled dose..

  • A pen contains one fixed dose; a powder vial is not the labeled formulation.
  • No validated community reconstitution volumes or home-mixed stability data were found.

Before mixing: Refrigerate at 2–8°C in the carton, protected from light. Never freeze.

After mixing: No mixing. May be kept below 30°C for a total of 14 days; discard after the single injection.

Dulaglutide side effects and risks

Reported side effects

  • Nausea: 0.75/1.5 mg: 12.4/21.1%; placebo 5.3%., moderate. Review persistent symptoms before increasing the dose; vomiting may cause dehydration. (source)

  • Diabetic eye complications: REWIND: 1.9% versus placebo 1.5%; with prior retinopathy, 8.5% versus 6.2%., serious. Monitor existing diabetic retinopathy, especially during rapid glucose improvement. (source)

  • Kidney injury from dehydration: Postmarketing cases, sometimes requiring dialysis; no reliable frequency., serious (source)

  • Thyroid C-cell tumors: Rodent finding; whether dulaglutide causes these tumors in humans is unknown., serious (source)

Stop and get help if

  • Severe, persistent belly pain, especially spreading to the back: Stop the drug and seek urgent care for possible pancreatitis.
  • Face or throat swelling, trouble breathing, or collapse: Call emergency services now; do not take another dose.
  • Confusion, seizure, fainting or low blood sugar that does not resolve: Get emergency care. If awake and able to swallow, use fast sugar while help is arranged.
  • Repeated vomiting, inability to keep fluids down, or very little urine: Seek urgent assessment for dehydration and kidney injury.
  • Upper-right belly pain with fever, yellow skin or pale stools: Seek urgent care for possible gallbladder or bile-duct disease.
  • Sudden vision loss or a major new change in vision: Get urgent same-day eye or emergency assessment.
  • Chest pain, marked breathlessness or fainting: Call emergency services now.

Who should avoid it

  • pregnant: Weight loss is unsuitable; fetal-risk data are limited and animal findings raise concern.
  • tryingToConceive: Review a stopping plan before conception; no safe conception interval was established in the extracted sources.
  • breastfeeding: Human milk and infant-safety data are inadequate.
  • under18: Some labeled diabetes or obesity uses include children; this is not a blanket pediatric label ban.
  • mtcOrMen2: Personal or family medullary thyroid cancer or MEN2 is a label contraindication for this GLP-1 product.
  • other: Do not re-expose after a serious allergic reaction to the drug or its ingredients.
  • pancreatitisHistory: Past pancreatitis needs review; stop and urgently assess persistent severe abdominal pain.
  • gallbladderDisease: Gallstones or previous gallbladder inflammation increase the need to assess new upper-abdominal pain.
  • gastroparesis: Severe gastroparesis is a label reason to avoid use; these medicines further slow stomach emptying.
  • eatingDisorderHistory: Listed as a reason to avoid it.
  • kidneyDisease: Kidney function and hydration need review, especially with vomiting or diarrhea.
  • liverDisease: Clinical experience in severe liver impairment is limited; review the specific product and other medicines.
  • diabeticRetinopathy: Rapid glucose improvement can temporarily worsen diabetic eye disease; arrange appropriate eye follow-up.
  • surgeryPlanned: Tell the anesthesia team. Delayed stomach emptying can leave food in the stomach despite fasting.
  • diabetes: Review glucose monitoring and insulin or sulfonylurea doses. Do not rapidly stop insulin.

Interactions

  • Insulin: Low blood sugar risk can rise. Insulin adjustment needs glucose readings; rapid withdrawal can cause ketoacidosis.
  • Sulfonylureas and related insulin-releasing drugs: Low blood sugar can increase; a clinician may need to lower the companion drug dose.
  • Another GLP-1 or GLP-1/GIP medicine: Avoid duplicate incretin therapy. Switching guidance stops the previous product rather than stacking both.
  • DPP-4 inhibitors: Routine combination is not recommended because it adds little glucose benefit over GLP-1 therapy alone.
  • Time-sensitive oral medicines: Slower stomach emptying can alter absorption timing; the effect is medicine-specific. Review critical oral drugs, especially with vomiting or poor intake.
  • Warfarin: Monitor INR with initiation or changes; the label advises caution with narrow-therapeutic-index oral drugs.

Product quality risks

  • Online GLP-1 products can contain the wrong amount, a different drug or contamination. A seller’s purity claim does not establish sterile injectable quality.
  • Three online semaglutide vials had 28.56–38.69% excess drug and endotoxin. Those samples were not this compound.
  • No direct laboratory survey of online dulaglutide products was found; semaglutide assay rates cannot be assigned to dulaglutide.

Dulaglutide FAQ

  • Is Dulaglutide FDA-approved? Yes: Trulicity (type 2 diabetes age 10+; fewer major heart events in adults with diabetes and cardiovascular disease or multiple risk factors.). No US weight-management indication. March 2026 prescribing information checked.
  • How do people take it? Under the skin, once weekly. Source: drug label.
  • Can I take it with Metformin? Most AWARD studies used metformin background therapy for type 2 diabetes. Stomach symptoms can overlap; each drug retains its separate precautions. Source: studied in a trial. Ask a doctor before combining anything.
  • Is it banned in sport? No, it is not on the banned list (WADA 2026). The 2026 monitoring program names semaglutide and tirzepatide, not this drug. Approved GLP-1 medicines remain permitted.
  • How do I store it once opened? No mixing. May be kept below 30°C for a total of 14 days; discard after the single injection.
