Vomiting on GLP-1: Fixes and Strategies

Putting this together involved looking at a couple of things: the valuable social wisdom that comes from real people, and the findings generated by scientific studies and research data. This material brings those two sources together.

Basic Strategies

• Urgent hydration: Small, frequent sips of clear fluids to prevent dehydration

• Medication timing: Take GLP-1 injections at bedtime to sleep through initial effects

• Injection site: Use thigh or arm instead of abdomen to reduce digestive disturbance

• Empty stomach hazard: Never let your stomach remain empty - keep bland snacks available

• Stop-resume eating: Wait 30 minutes after vomiting before eating again

• Food choices: Plain, bland foods like rice, toast, bananas

• Posture: Remain upright for at least 30 minutes after eating

By Severity Level

Occasional Vomiting

• Ice chips: Slowly suck on ice chips when fluids won't stay down

• Electrolyte replacement: Diluted sports drinks or pediatric electrolyte solutions

• Cold compresses: Apply to forehead or back of neck during episodes

• Ginger protocol: Ginger tea, candies, or capsules taken preventatively

• Acupressure: Sea-bands or pressure on P6 point (inner wrist)

• Deep breathing: Practice controlled breathing when feeling nauseated

Recurrent Vomiting

• OTC antiemetics: Non-drowsy Dramamine, Emetrol, Nauzene

• Dose adjustment: Consult doctor about temporary dose reduction

• Clear liquid diet: When actively vomiting, temporarily switch to clear liquids only

• Alcohol pad technique: Sniff alcohol prep pads at first sign of nausea

• Split dosing: Ask doctor about splitting the dose (half dose twice weekly)

• Pre-medication: Take approved anti-nausea medication 30-60 minutes before GLP-1 dose

Severe/Persistent Vomiting

• Medical attention: Seek immediate care for dehydration signs (dark urine, dizziness)

• Prescription antiemetics: Zofran (ondansetron), especially dissolvable tablets

• IV hydration: May be necessary if unable to maintain fluid intake

• Medication pause: Temporary suspension of GLP-1 (only with medical supervision)

• Alternative GLP-1: Discuss switching to different GLP-1 medication with physician

• Rule out complications: Medical evaluation to ensure no other issues like bowel obstruction

Warning Signs (Seek Immediate Medical Care)

• Inability to keep down any fluids for 12+ hours

• Signs of dehydration (excessive thirst, dry mouth, little/no urination, dizziness)

• Blood in vomit or stool

• Severe abdominal pain

• Fever with vomiting

• Rapid heartbeat or breathing
