If you’re one of the over 37 million Americans living with type 2 diabetes, keeping your blood sugar under control is likely a constant concern. With diet, exercise and various medications prescribed, balancing treatment while going about your daily life can feel like a major challenge.
If you’ve been prescribed the common oral diabetes drug metformin but still struggle to lower your A1c, adding an injectable medication like semaglutide may provide more effective blood sugar control. But is it safe to take both semaglutide and metformin together?
This article will provide a deep dive into how semaglutide and metformin work as diabetes medications, the potential benefits and risks of combining these treatments, and guidance on how to take the drugs together safely and effectively for optimal blood sugar management.

As an affordable generic medication that has been used to treat type 2 diabetes for over 60 years, metformin is generally the first oral drug prescribed for new diagnoses. It works by lowering glucose production in the liver and improving the body’s sensitivity to insulin.
Taken as a pill or liquid two to three times per day with meals, metformin has a good track record for safety and effectiveness when used properly under medical supervision. Here’s a breakdown of its benefits and potential side effects.
|Benefits of Metformin||Side Effects of Metformin|
|Improves A1c by 1-2% on average||Digestive issues like diarrhea, nausea, vomiting|
|Low risk of blood sugar dropping too low (hypoglycemia)||Metallic taste in the mouth|
|Helps with weight loss and maintenance||Loss of appetite and indigestion|
|Cardiovascular benefits shown in some studies||Fatigue|
|Inexpensive generic available||Muscle pain|
Rarer but serious risks like lactic acidosis are also possible if metformin builds up in the blood due to kidney dysfunction. For this reason, kidney health and liver function are checked through blood tests before starting metformin and during treatment. Overall, metformin is considered very safe if taken correctly, but side effects and health parameters do need to be watched.
If metformin alone is not keeping your blood sugar well controlled or you want to minimize side effects, adding an injectable diabetes medication like semaglutide may improve results. Semaglutide is a newer drug approved by the FDA for treating type 2 diabetes, offering a different mechanism of action than oral agents. As a GLP-1 receptor agonist, semaglutide works by mimicking the glucagon-like peptide-1 hormone to stimulate insulin secretion, suppress liver glucose production, and slow stomach emptying.
Unlike metformin, semaglutide is taken as a once-weekly injection just under the skin. Some of the advantages of semaglutide treatment include:
The most common side effects of semaglutide are gastrointestinal like nausea, vomiting, and diarrhea. These tend to be worse when first starting and improve over time. Like any diabetes medication, semaglutide also carries a risk of hypoglycemia as well.
Overall, the differences between how metformin and semaglutide work to control blood sugar means that combining the two offers complementary effects for better A1c improvement, according to research. But is taking both drugs together safe and what should you know before adding semaglutide to metformin treatment?
For adults with type 2 diabetes not meeting treatment goals with metformin alone, the addition of semaglutide provides a safe and effective option to lower A1c. Multiple clinical studies have shown the benefits of combining these two glucose-lowering medications:
Importantly, there were no negative pharmacokinetic interactions found when semaglutide and metformin were taken together. Each drug was absorbed as expected and there were no major changes in overall exposure. The safety profile of combined treatment also did not raise any new concerns beyond the known risks of each individual medication.
Here’s a summary of vital factors and details to consider when combining these two drugs.
|Important Factors||Top Facts and Considerations|
|Optimal timing||More research is needed on the best time to take semaglutide & metformin Some experts suggest taking at opposite times of dayWork with doctor for ideal dosing schedule|
|Side effect risks||Combining meds increases side effects Monitor feelings and report concerns GI issues more likely, start semaglutide low & ramp slowlyIncreased hypoglycemia risk, especially if older or kidney disease|
|Safety considerations||Combo safety demonstrated in trialsLong-term effects need more studyProvider should monitor closely with A1c checks, adjustments, screening|
If you and your doctor decide to start injectable semaglutide together with your usual metformin medication, keep these tips in mind for success:
Remember that any regimen does require commitment from you as the patient to follow medical advice, report concerns promptly, and stay engaged with your healthcare team. Ongoing medical supervision ensures semaglutide and metformin are working safely and effectively together to successfully manage your blood sugar long-term.
If type 2 diabetes has you frustrated with metformin monotherapy, take heart that additional options like semaglutide exist to get your A1c down where you want it. Combining the complementary mechanisms of a longstanding oral medication like metformin with the advanced efficacy of a GLP-1 injected solution like semaglutide may offer the advantage you need to finally gain control of your blood sugar.
Monitoring for increased side effects and being diligent with your co-administered drugs is key to success. If you want to learn more about adding semaglutide to your diabetes treatment plan, know that Dr. V Medical Aesthetics offers Ozempic prescribed by a licensed medical provider.
