Note that compounded semaglutide, which Trimi prescribes, is not FDA-approved, while Ro's 2026 announcements describe its weight-loss offering in terms of FDA-approved GLP-1 medications such as Wegovy.

Serious Side Effects: When to Seek Emergency Care
Severe, persistent abdominal pain that radiates to the back, possible pancreatitis, which requires immediate emergency evaluation
Signs of allergic reaction including rash, swelling of face or throat, or difficulty breathing, seek emergency care immediately
Persistent vomiting that prevents you from keeping down fluids, risk of severe dehydration and electrolyte imbalances
Signs of kidney problems including decreased urination, dark urine, or swelling in legs and ankles, especially concerning if combined with dehydration
Changes in vision, particularly if you have a history of diabetic retinopathy, GLP-1 medications have been associated with rare worsening of pre-existing retinopathy
Symptoms of gallbladder problems including severe upper right abdominal pain, fever, or jaundice, gallstones can occur with rapid weight loss
These serious side effects require in-person emergency medical attention regardless of your telehealth provider. The FDA's safety communication on GLP-1 medications underscores why prompt clinical oversight matters. No telehealth platform, Ro, Trimi, or any other, is a substitute for emergency care. Our important safety information page provides comprehensive guidance on GLP-1 safety monitoring.

Frequently Asked Questions
What should I do if I have serious side effects on Ro?
If you experience serious side effects such as severe persistent vomiting, signs of pancreatitis (severe abdominal pain radiating to the back), allergic reactions (rash, swelling, difficulty breathing), significant dehydration, or signs of kidney problems, seek immediate emergency medical attention regardless of your provider. Do not wait for a telehealth response for serious or emergency symptoms. After stabilization, inform your Ro provider about what happened so they can adjust your treatment plan. Serious adverse events require in-person emergency care, not telehealth messaging.
