Key Takeaways
- Each approved semaglutide product, injection or tablet, has its own dosing schedule, written for the use it's approved for.
- Every approved schedule starts low and steps up gradually, which helps your body adjust.
- Your provider sets your schedule and adjusts it based on how you're doing.
- If your prescription is compounded, your provider writes your schedule.
When you start semaglutide, it helps to know what the weeks ahead might look like. That depends on which product you take, because each approved product has its own schedule.
The Approved Semaglutide Schedules
| Product | How it's taken | What its schedule is written for |
|---|---|---|
| Semaglutide injection, diabetes | Under the skin, weekly | Blood sugar control in adults with type 2 diabetes |
| Semaglutide injection, weight | Under the skin, weekly | Weight reduction and cardiovascular risk reduction, in specific groups |
| Semaglutide tablets, diabetes | By mouth, daily | Blood sugar control in adults with type 2 diabetes |
| Semaglutide tablets, weight | By mouth, daily | Weight reduction and cardiovascular risk reduction in adults |
| Compounded semaglutide | As prescribed | No approved schedule, because it has no label† |
Your prescription tells you which row is yours.
How Is Every Approved Schedule Built?
In the same three parts: a starting period, step-ups and an ongoing dose.
A starting period. Each approved product starts at one dose and stays there for a set number of weeks. Both the diabetes injection labeling and the weight-management labeling set out this opening period.
Step-ups. The dose then goes up in set steps at set times, not gradually every day and not based on how one week went.
An ongoing dose. The schedule settles at a dose that continues, and that dose differs by approved use, even within one product.
Why Approved Schedules Go Up in Steps
To help your body adjust. Stomach side effects such as nausea are the most common with semaglutide, so every schedule starts low and steps up gradually rather than starting at the top.
Why Do Oral and Injected Schedules Look So Different?
Because your body absorbs far less from a tablet than from an injection.
Your body absorbs about 89 percent of a dose injected under the skin, compared with roughly 1 to 2 percent of an oral tablet. So the tablets contain a much larger amount and come with strict instructions on timing.
An oral semaglutide tablet is taken in the morning on an empty stomach, swallowed whole with a small amount of water and nothing else. Then you wait before eating, drinking or taking anything else.
Even the two semaglutide tablets for diabetes aren't substitutable on a milligram-for-milligram basis, so a dose only applies to the product it was written for.
EVERY APPROVED SCHEDULE
Three parts, in the same order.
- Starting period the same dose for a set number of weeks, to help your body adjust
- Step-ups at set times, following the label, not how one week went
- Ongoing dose differs by approved use, even within one product
Each approved semaglutide product has its own schedule on its own label. A compounded preparation has none, because it has no label.
A dose for one product doesn't carry over to another.
What About Compounded Semaglutide?
It doesn't have an approved schedule, because it doesn't have an approved label.†
A compounded preparation is made by a licensed pharmacy specifically for you, and its strength can differ from an approved product's.
So your provider writes your schedule for your prescribed strength, which is printed on your vial. Compounded semaglutide vs Ozempic explains how the two differ.
Common Side Effects and Who Should Be Careful
The most common side effects listed on the semaglutide labels are stomach-related: nausea, vomiting, diarrhea, abdominal pain and constipation.
Semaglutide isn't a fit for everyone, so before you start your provider will go over:
- Your thyroid history: a personal or family history of medullary thyroid cancer or MEN 2.
- Conditions you've had: pancreatitis, gallbladder disease or kidney problems.
- Medicines you take: especially diabetes medicines that can lower blood sugar.
- Any allergies: any serious allergic reaction to a medicine.
When Does a Chart Stop Applying?
Your provider is a better guide than any chart in these cases:
- You're on a different product than the chart describes. Check the product name on your label, not the ingredient name, before you follow any schedule.
- You've missed a dose. There's a rule for this, and your provider will walk you through it.
- You're switching to a different form or product. The approved labels explain how to switch, and your provider will guide you through it.
- A step feels like too much. Tell your provider. There's some room to adjust your schedule, and your provider decides what to change.
Your own schedule comes after an evaluation, where a licensed provider reviews your health history first.
Frequently Asked Questions
Is there one semaglutide dosage chart?
No. Semaglutide is in several approved products, each with its own schedule on its own label for its own indication. It depends on which product you take.
Why does the dose start low?
To help your body adjust. In the weight-management trials of the injection, nausea was reported by 44% of people on semaglutide and 16% on placebo, diarrhea by 30% and 16%, and vomiting by 24% and 6%. Every approved schedule starts low and steps up to make that easier.
What does the boxed warning on semaglutide labels say?
The Ozempic label carries a boxed warning about thyroid C-cell tumors, and the weight-management label carries the same warning. A boxed warning is printed in a box at the start of a prescription label and covers its most serious risks. Semaglutide caused these tumors in rodents; it isn't known whether it does in people. The labels say semaglutide isn't for anyone with a personal or family history of medullary thyroid cancer or MEN 2, or a serious allergy to semaglutide. The label notes that routine blood tests (calcitonin) or thyroid ultrasound are of uncertain value for catching these tumors early, so tell your provider about a lump in your neck, trouble swallowing, shortness of breath or hoarseness that doesn't go away.
Can I use an approved chart for a compounded preparation?
No approved schedule covers a compounded preparation, because it has no label. Your prescriber writes the schedule for the strength on your vial.
Why are the oral doses so much larger than the injected ones?
Because your body absorbs far less from a tablet. The labeling puts it at about 89 percent of a dose injected under the skin and roughly 1 to 2 percent of a tablet, so the tablets contain a much larger amount.
