Can I take Ozempic tablets with metformin?
Yes, the label covers it. Semaglutide tablets were studied alone and together with metformin, and an interaction study found no clinically significant change in metformin levels. The morning rule still applies: metformin, like any other oral medicine, waits at least 30 minutes after the tablet.

The short answer
Yes, the label covers it. Semaglutide tablets were studied alone and together with metformin, and an interaction study found no clinically significant change in metformin levels. The morning rule still applies: metformin, like any other oral medicine, waits at least 30 minutes after the tablet.
What the label says
Metformin is named several times in the Ozempic tablets label, which Ozempic tablets share with Rybelsus. Three passages answer the question.
They were studied together
The clinical studies section, §14, describes the trials:
From the labelSemaglutide tablets have been studied as monotherapy and in combination with metformin, sulfonylureas, sodium-glucose co-transporter-2 (SGLT-2) inhibitors, insulins, and thiazolidinediones in patients with type 2 diabetes mellitus.
Those trials were run with Rybelsus, and the label says the effectiveness of Ozempic tablets is established on the basis of those Rybelsus studies. Several of the trials it describes are headed "Combination with Metformin".
Metformin levels were measured
The clinical pharmacology section, §12.3, reports interaction studies with common medicines:
From the labelNo clinically significant differences in the pharmacokinetics of the following drugs were observed when used concomitantly with semaglutide: lisinopril, S-warfarin, R-warfarin, metformin, digoxin, ethinyl estradiol, levonorgestrel, furosemide or rosuvastatin.
Pharmacokinetics means how much of a drug reaches the blood and for how long. In plain words: taking semaglutide tablets did not meaningfully change metformin levels in the study.
The timing rule still applies
The interaction study does not change the morning rule in §2.1:
From the labelAfter taking RYBELSUS or OZEMPIC tablets, wait at least 30 minutes before eating food, drinking beverages or taking other oral medications.
Metformin is an oral medication, so it comes after the 30 minutes, never with the tablet's glass of water.
Low blood sugar: what the label names
The warning on low blood sugar, §5.4, is about two other kinds of diabetes medicine:
From the labelPatients receiving RYBELSUS or OZEMPIC tablets in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.
The adverse reactions section, §6.1, says the same from the trial results:
From the labelHypoglycemia was more frequent when semaglutide tablets were used in combination with insulin secretagogues (e.g., sulfonylureas) or insulin.
Metformin is not in either sentence. If a sulfonylurea or insulin is part of the treatment as well, the label says lowering its dose may reduce the risk, and that is the prescriber's call. The Medication Guide asks:
From the labelTell your healthcare provider if you are taking other medicines to treat diabetes, including insulin or sulfonylureas.
A morning that works
The label's order is simple: the tablet first thing with a little water, then 30 minutes, then breakfast, coffee and the other morning medicines, metformin included if it is taken in the morning. A metformin dose taken later in the day is not touched by the rule at all. Any change to when or how much metformin is taken belongs to the prescriber who set it.
Oolite logs the morning tablet and the time it was taken, and keeps a journal of how each day felt for the report at the next appointment.
Questions people ask
Can I swallow my metformin with the same glass of water?
No. The label says to wait at least 30 minutes after the tablet before taking other oral medications. Metformin comes after the wait, with the rest of the morning.
My metformin is meant to be taken with breakfast. Does that still work?
The label's rule is only about the 30 minutes after the tablet. Once they have passed, food and other medicines can follow. How and when to take metformin is set by your prescriber.
Does adding Ozempic tablets to metformin cause low blood sugar?
The label links a higher risk of low blood sugar to insulin secretagogues such as sulfonylureas and to insulin, not to metformin. If you take one of those as well, your prescriber may adjust it.
Should I stop metformin when I start Ozempic tablets?
The label does not say to. It describes the tablets studied in combination with metformin. Any change to your diabetes medicines is your prescriber's decision.
