Positives

• Dulaglutide could be relevant for patients who have Long COVID alongside diabetes, insulin resistance, or blood-sugar swings that seem to worsen fatigue, brain fog, or crashes (Drugs.com).
• As a weekly GLP-1 medication, it may be easier to manage than daily medications for patients with cognitive load or treatment fatigue (WebMD).

Negatives

• Its main evidence base is diabetes and cardiometabolic care, not Long COVID or ME/CFS symptom improvement (Drugs.com).
• Patient reviews and side-effect summaries describe nausea, vomiting, diarrhea, appetite loss, and GI distress, which can be hard on people with dysautonomia or limited food tolerance (Drugs.com).

Hurdles & Side Effects

• Patients interested for chronic illness reasons would generally need another accepted indication or a clinician comfortable with off-label reasoning (Drugs.com).
• It should be approached carefully in patients with gastroparesis-like symptoms, dehydration risk, or difficulty maintaining nutrition (Drugs.com).
