The normal dose of semaglutide depends on whether you’re taking it for weight loss or type 2 diabetes, and whether it’s an injection or a pill. For weight loss injections (Wegovy), the standard maintenance dose is 2.4 mg once per week. For diabetes injections (Ozempic), most people settle at 0.5 mg or 1 mg per week. The oral tablet (Rybelsus) tops out at 14 mg daily. None of these are starting doses, though. Every form of semaglutide begins at a much lower amount and increases gradually over weeks.
Weight Loss Injection Doses (Wegovy)
Wegovy uses a five-step schedule that takes about 16 weeks before you reach the full dose. You start low so your body adjusts to the medication, which significantly reduces nausea and other stomach-related side effects. Here’s how the schedule breaks down:
- Weeks 1 through 4: 0.25 mg once per week
- Weeks 5 through 8: 0.5 mg once per week
- Weeks 9 through 12: 1 mg once per week
- Weeks 13 through 16: 1.7 mg once per week
- Week 17 onward: 2.4 mg once per week (maintenance)
Each step lasts exactly four weeks before moving up. The recommended maintenance dose for adults is 2.4 mg weekly, but if that causes persistent side effects, 1.7 mg is an accepted alternative maintenance dose. For adolescents aged 12 and older, the target is 2.4 mg weekly with the same gradual ramp-up.
In early 2025, the FDA also approved Wegovy HD at 7.2 mg per week for certain adults. This higher-dose option is intended for people who need additional weight loss beyond what the standard 2.4 mg provides.
Diabetes Injection Doses (Ozempic)
Ozempic follows a simpler escalation. You start at 0.25 mg once per week for the first four weeks. At week five, the dose moves to 0.5 mg. For many people with type 2 diabetes, 0.5 mg provides enough blood sugar control and becomes their long-term dose.
If more control is needed after at least four weeks at 0.5 mg, the dose can increase to 1 mg weekly. The doses used for diabetes are notably lower than those used for weight management, which reflects the different treatment goals. Blood sugar regulation responds to smaller amounts of semaglutide than the appetite and body weight pathways do.
Oral Tablet Doses (Rybelsus)
The pill form of semaglutide, prescribed for type 2 diabetes, uses a completely different dosing scale because oral absorption works differently than injection. You start at 3 mg once daily for 30 days. This starting dose is purely for getting your body used to the medication and has no real effect on blood sugar on its own.
After 30 days, the dose increases to 7 mg daily. If blood sugar levels still need improvement after another 30 days at 7 mg, you can move up to 14 mg daily, which is the maximum oral dose. One important detail: taking two 7 mg tablets to get 14 mg doesn’t work the same way as a single 14 mg tablet, so that substitution isn’t recommended.
Why the Dose Starts So Low
Semaglutide works by mimicking a hormone your gut naturally produces after eating. When you introduce it from outside the body, your digestive system needs time to adapt. Jumping straight to a full dose commonly causes nausea, vomiting, and diarrhea. The slow four-week-per-step escalation gives your stomach and intestines time to adjust at each level, making the transition to the maintenance dose much more tolerable.
If side effects are still bothersome at a particular step, staying at that dose for longer than four weeks before moving up is a common strategy. The schedule is a minimum timeline, not a rigid one.
No Dose Adjustments for Most Health Conditions
Unlike many medications, semaglutide does not require dose changes based on age, sex, body weight, kidney function, or liver function. FDA clinical pharmacology reviews found that the drug’s absorption and blood levels stay consistent across all of these groups, including people with significant kidney or liver impairment. This means the same standard titration schedule applies whether you’re 25 or 75, and whether your kidneys work normally or are substantially impaired.
Injection Sites and Timing
Weekly semaglutide injections go under the skin in one of three areas: the abdomen, the front of the thigh, or the upper arm. You can pick the same general area each week, but shift the exact spot slightly to avoid irritation. Steer clear of skin that’s bruised, red, scarred, or hard.
You choose a day of the week for your injection and keep that day consistent. The injection can be given at any time of day, with or without food. If you miss a dose and fewer than five days have passed since it was due, take it as soon as you remember. If more than five days have passed, skip that dose and take the next one on your regular day.
For the oral tablet, timing matters more. Rybelsus needs to be taken on an empty stomach with no more than four ounces of plain water, at least 30 minutes before eating, drinking anything else, or taking other medications. This specific routine is necessary because the pill’s absorption is easily disrupted by food and other substances in the stomach.
