Can I take a GLP-1 with metformin?

Yes — the combination is FDA-approved and commonly prescribed for type 2 diabetes. There is no metabolic interaction. The two share a GI side-effect profile, so titrate the GLP-1 slowly to minimize compounding nausea.

Is Rybelsus (oral semaglutide) as effective as Ozempic (injectable)?

Rybelsus 14 mg daily is roughly equivalent to Ozempic 0.5 mg weekly for A1c reduction. For weight loss, injectable doses (up to 2.4 mg Wegovy) are substantially more effective than the current oral 14 mg max. Higher-dose oral semaglutide (25 mg, 50 mg) is in development.
