Rybelsus is semaglutide, the same medicine as Ozempic, in a once-daily pill for adults with type 2 diabetes. It lowers A1c, often helps with weight, and since October 2025 is also FDA-approved to lower the risk of heart attack, stroke, and cardiovascular death in high-risk adults with type 2 diabetes. It must be taken on an empty stomach with a small sip of water, followed by a 30-minute wait.
Rybelsus was the first GLP-1 medicine available as a pill. Like all GLP-1 medicines, it helps the pancreas release insulin when blood sugar is high, lowers the liver's sugar output, slows stomach emptying, and reduces appetite. It does not cause low blood sugar on its own, though lows can happen if it is combined with insulin or a sulfonylurea. See our GLP-1 medications guide for how it fits with the other options.
How to Take Rybelsus
- Take one tablet each morning when you wake up, on an empty stomach
- Swallow it whole with no more than 4 ounces (half a glass) of plain water
- Wait at least 30 minutes before eating, drinking anything else, or taking other morning pills
- Do not split, crush, or chew the tablet
- Missed a dose? Skip it and take your usual dose the next morning
💊 On levothyroxine? Rybelsus can increase how much levothyroxine is absorbed, so your thyroid levels may be rechecked after you start. Ask us how to time your morning medicines.
Tablet Strengths
Rybelsus is started at a low dose for 30 days and then increased, which helps limit stomach side effects. It is now made in two tablet versions: the original 3 mg, 7 mg, and 14 mg tablets, and a newer formulation in 1.5 mg, 4 mg, and 9 mg. The newer tablets are made to give a similar effect at a lower milligram number, so the two versions are not interchangeable milligram-for-milligram. Check that each refill matches what your provider prescribed, and call us if the tablet strength on your bottle changes unexpectedly.
Heart Protection
The SOUL trial followed about 9,650 adults with type 2 diabetes and heart disease, chronic kidney disease, or both, for an average of about 4 years. Those taking Rybelsus had a 14% lower risk of heart attack, stroke, or cardiovascular death than those on placebo. In October 2025 the FDA added this benefit to the label for high-risk adults with type 2 diabetes, whether or not they have already had a heart attack or stroke. That makes Rybelsus the first GLP-1 pill with a proven heart benefit.
Rybelsus vs. Other Semaglutide Products
| Product | Form | Approved for |
|---|---|---|
| Rybelsus | Daily tablet | Type 2 diabetes; cardiovascular risk reduction in high-risk type 2 diabetes |
| Ozempic | Weekly injection | Type 2 diabetes; heart and kidney protection |
| Wegovy pill | Daily tablet (25 mg maintenance) | Weight management |
| Wegovy injection | Weekly injection | Weight management; cardiovascular risk reduction |
Never take two semaglutide products, or any two GLP-1 medicines, at the same time.
Side Effects
The most common side effects are gastrointestinal: nausea, diarrhea, vomiting, constipation, stomach pain, and decreased appetite. They are most noticeable when starting or increasing the dose and usually improve. Smaller meals and stopping when you feel full can help.
⚠️ Important safety information: Rybelsus has a boxed warning about thyroid C-cell tumors seen in animal studies. Do not take it if you or a family member has had medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Other risks include pancreatitis, gallbladder problems, kidney problems from dehydration, low blood sugar when combined with insulin or a sulfonylurea, and worsening of diabetic eye disease (retinopathy) in some people. Stop it at least 2 months before a planned pregnancy.
