Key takeaways
- • Severity: No clinically significant interaction known.
- • Wegovy (weight management (FDA-approved obesity)) and Losartan (Cozaar) (ARB (cardiovascular)).
- • Clinical management: Continue as prescribed; reassess BP regimen as weight changes.
- • Monitoring: Routine BP and renal function checks; potassium per ARB practice.
Mechanism
Losartan is not affected meaningfully by GLP-1-induced gastric emptying changes. Cumulative blood pressure lowering from weight loss may occur but is monitored clinically, not avoided.
Clinical management
Continue as prescribed; reassess BP regimen as weight changes.
GLP1Zoom does not prescribe medications or recommend dose changes. Always confirm any adjustment with your prescribing clinician before changing how you take Wegovy or Losartan (Cozaar).
Monitoring
Routine BP and renal function checks; potassium per ARB practice.
When to call your doctor
