The Short Answer
Rybelsus and Ozempic both contain semaglutide, but Rybelsus is a daily oral pill while Ozempic is a weekly injection. The injection is generally more effective (higher blood levels), but Rybelsus offers convenience for patients who can't or won't inject. Both are FDA-approved for type 2 diabetes.

Key Differences
- Ozempic (injection) is generally more effective because oral semaglutide has reduced bioavailability — your body absorbs less of the pill
- Rybelsus requires strict adherence to absorption rules: empty stomach, only 4 oz water, wait 30 minutes before eating — missing this significantly reduces effectiveness
- Rybelsus is daily; Ozempic is weekly — some patients prefer the convenience of weekly injections over daily pills with strict timing
- Ozempic reaches higher blood levels, which typically means better blood sugar control and more weight loss
