Managing diabetes often involves more than just food and lifestyle changes—medications can play a key role in helping keep blood sugar levels in check, whether you’re newly diagnosed or navigating modifications to your treatment plan. Understanding how different diabetes medications work can empower you to make informed decisions about your health. In this post, we’ll break down the basics, answer common questions, and help you feel more confident in your diabetes care journey.

I want to be clear—I’m not here to push medications. However, it’s essential to recognize that diabetes is a progressive disease. Over time, the body may naturally produce less insulin or become more resistant to it, even with the best nutrition and exercise habits in place. For many people I’ve seen in my office, there’s a strong desire to manage diabetes without medication, and while that can work for a while, it’s not always realistic long term. Needing medication is not a sign of failure—it’s a tool to support your body and protect your long-term health.
Why Are Medications Used?
Diabetes occurs when the body either doesn’t make enough insulin, doesn’t use insulin effectively, or both. Over time, lifestyle changes such as balanced meals, regular movement, and stress management can make a significant difference—but sometimes they’re not enough to keep blood sugar levels within a safe range. That’s where medications come in. Helping the body remove excess glucose through the urine via the kidneys
Medications can help by:
- Increasing insulin production
- Improving insulin sensitivity
- Slowing down glucose absorption
- Assisting the body in removing excess glucose through the urine via the kidneys
- Replacing or supplementing insulin
Types of Diabetes Medications
- Oral Medications (Mostly for Type 2 Diabetes)
These are pills or tablets taken by mouth and work in various ways. Common classes include:
- Metformin – Often the first-line medication; it helps reduce glucose production in the liver and improves insulin sensitivity.
- SGLT-2 Inhibitors (e.g., Jardiance, Farxiga) – Help the kidneys release extra glucose through the urine. (Caution to be aware of UTIs).
- GLP-1 Receptor Agonists (oral form) – Stimulate insulin release, slow digestion, and help reduce appetite.
- Sulfonylureas – Stimulate the pancreas to produce more insulin (less commonly used now); however, these can also cause hypoglycemia if you go too long without eating.
- DPP-4 Inhibitors – Help prolong the effect of incretin hormones that regulate insulin.
2. Injectable Medications
Not all injectables are insulin! While insulin is one of the most well-known injectable medications for diabetes, several non-insulin options are available that work in different ways to support blood sugar management. These medications can be a helpful option for people with type 2 diabetes who need additional support beyond oral medicines.
- Insulin – Used in both type 1 and some type 2 diabetes cases when the body isn’t making enough insulin on its own. In type 1 diabetes, the pancreas does not produce insulin; therefore, insulin needs to be replaced. In Type 2 diabetes, over time, the pancreas produces less insulin and may also become resistant, making insulin supplementation or replacement necessary.
- GLP-1 Receptor Agonists (injectable) – Like Ozempic, Trulicity, or Mounjaro, these mimic a gut hormone to increase insulin, decrease glucagon, and slow digestion.
3. Combination Medications
Sometimes medications are combined into one pill or injection to reduce pill burden and improve convenience. These combinations are designed to target different aspects of glucose control in a single convenient dose, helping to improve adherence and simplify diabetes management. However, they can also be quite expensive at times. Discuss with your healthcare provider and diabetes team.
- Janumet – Combines metformin and sitagliptin (a DPP-4 inhibitor)
- Synjardy – Combines metformin and empagliflozin (an SGLT-2 inhibitor)
- Xigduo XR – Combines metformin and dapagliflozin (an SGLT-2 inhibitor)
- Trijardy XR – Combines metformin, empagliflozin (SGLT-2 inhibitor), and linagliptin (DPP-4 inhibitor)
- Kombiglyze XR – Combines metformin and saxagliptin (DPP-4 inhibitor)
Insulin: A Closer Look
Insulin is a must for people with type 1 diabetes and is often needed for those with type 2 when other medications aren’t enough. There are different types of insulin based on how quickly they act and how long they last:
- Rapid-acting (e.g., Novolog, Humalog)
- Short-acting (e.g., Regular)
- Intermediate-acting (e.g., NPH)
- Long-acting (e.g., Lantus, Tresiba)
- Premixed insulin – A combination of two types (ex., Novolog Mix 70/30 – 70% insulin aspart protamine (intermediate-acting) and 30% insulin aspart (rapid-acting)
The timing, dose, and type of insulin depend on your individual needs, meal patterns, and blood sugar trends.
How Do I Know If I Need Medication?
Your healthcare provider will consider your blood sugar levels (A1C and daily readings), medical history, and lifestyle before recommending medications. Even if you’re doing “everything right” with food and exercise, diabetes is a progressive condition, and needing medication is not a failure. It’s a tool to help keep you healthy and prevent complications.
Tips for Taking Diabetes Medications
- Be consistent. Take medications at the same time each day as instructed.
- Communicate. Let your provider know if you experience side effects. Appointments may not be scheduled for 3 months; however, please communicate with us between appointments if any issues arise.
- Understand your meds. Ask how they work, when to take them, and what to expect. Too many times, I’d see patients taking a medication on days when their blood sugar levels were elevated, only to take the medication then not if their blood sugar level was within normal limits. Unfortunately, that’s not how medicines work.
- Stay stocked. Don’t wait until you run out—refill ahead of time.
- Keep a list. Especially helpful if you see multiple healthcare providers.
Final Thoughts
There’s no one-size-fits-all approach to diabetes care, and medications are just one piece of the puzzle. Whether you’re taking insulin, oral meds, or none at all, remember that managing diabetes is about building sustainable habits for long-term health. Medications can be powerful tools—paired with a balanced diet, movement, and self-care—to help you feel your best and protect your health over time.
