Dosage & timing

Recommended Dosage:

Prescription-only, clinician-prescribed. Subcutaneous 0.75 mg once weekly to start, usually escalated to 1.5 mg; 3.0 mg and 4.5 mg once-weekly doses are available for additional glycemic lowering. DO NOT self-dose.

Warnings

This is a PRESCRIPTION DRUG, not a dietary supplement — use only under a clinician's care for an approved medical indication.
US FDA labeling includes a boxed warning about thyroid C-cell tumors: dulaglutide caused these tumors in rodents; relevance to humans is uncertain. Under the US label it is contraindicated with a personal or family history of medullary thyroid carcinoma (MTC) or MEN2. For treatment in Germany or Austria, consult the current EU product information for the exact medicine’s locally approved indications, contraindications and warnings; discuss any thyroid history with the prescriber.
Risk of acute pancreatitis — discontinue and seek care for severe persistent abdominal pain.
Risk of gallbladder disease (gallstones, cholecystitis).
Gastrointestinal adverse effects (nausea, vomiting, diarrhea) are very common, especially during dose escalation.
Weight loss is real but modest and includes some loss of lean mass — pair sustained weight loss with resistance training and adequate protein.
Avoid COMPOUNDED / grey-market GLP-1 products: risk of dosing errors, impurities, and unapproved salt forms. Use only pharmacy-dispensed product.
Not for cosmetic weight loss without a genuine medical indication.
May increase hypoglycemia risk when combined with insulin or sulfonylureas (dose adjustment needed).
