Semaglutide
DiabetesAlso known as Ozempic, Rybelsus, Wegovy
Semaglutide copies a gut hormone that tells your body to release insulin after meals, slows how fast your stomach empties, and quiets appetite — which is why it lowers blood sugar and often leads to weight loss. Ozempic and Wegovy are once-weekly injections; Rybelsus is a daily tablet. The honest truth: nausea early on is very common, but for most people it fades as the body adjusts.
How to take it
When
Injections are once a week, same day each week. The Rybelsus tablet is daily, first thing in the morning with a small sip of water, at least 30 minutes before food or other pills.
Food
Smaller meals help a lot with nausea, especially in the first weeks. Heavy, greasy meals tend to make it worse.
Avoid
Don't use it if you or your family have had medullary thyroid cancer or MEN 2 — and always tell your doctor your history first.
Tell your doctors
It slows stomach emptying, so tell any anesthesiologist, surgeon, or new doctor you're on it before procedures.
Missed a dose?
For weekly shots, take a missed dose within a few days if you remember in time — otherwise skip it and stay on your regular day. For the daily tablet, skip a missed dose and take the next one the following morning. Never double up.
