Type 2 Diabetes Medications: Metformin and Other Drug Groups

You're sitting in the doctor's office. Fresh test results in front of you. The doctor says calmly: "Type 2 diabetes. We need to start treatment." And suddenly a thousand questions are racing through your mind. What does this mean? What medications? For how long? Does this mean life is over?

No, life doesn't end. You have a big influence on what it will look like. Your doctor decides on medication; this article shows which groups of medicines exist, what to ask and what you can do yourself.

I won't lie to you - diabetes requires effort. But with the right knowledge and support, you can live a long, healthy and active life. Let's start from the beginning.

How does diabetes actually work? A quick explanation

Imagine that your cells are houses and glucose (blood sugar) is a parcel that needs to be delivered inside. Insulin is the courier - it opens the door and brings the parcel in. The problem with type 2 diabetes? Either there aren't enough couriers (the pancreas doesn't produce enough insulin), or the doors are broken (cells are resistant to insulin). The result? Parcels pile up outside the house - glucose circulates in the blood, unable to enter the cells.

Treatment is chosen by your doctor. They decide whether you need medication, which one and at what dose.

Groups of type 2 diabetes medications

All the medicines in this part of the article are prescription-only. We do not describe how they work, what side effects they have or who they are prescribed for. Whether to take a medicine, which one and at what dose is decided by your doctor, and the full information on each medicine is in its package leaflet. We do not compare prices of prescription medicines.

To make it easier to talk to your doctor and pharmacist, here are the group names and example active substances:

• Metformin - tablets, including prolonged-release forms.
• Sulfonylureas - e.g. glibenclamide, gliclazide.
• DPP-4 inhibitors - e.g. sitagliptin, vildagliptin.
• GLP-1 receptor agonists - e.g. liraglutide, dulaglutide, semaglutide. Not all of them are injections: semaglutide also comes as tablets (Rybelsus).
• SGLT2 inhibitors - e.g. dapagliflozin, empagliflozin.
• Insulin - several types that differ in how long they act.

What to keep in mind with every medicine

• Read the package leaflet. It tells you how to take the medicine, when not to use it, what side effects it may have and what to do if you miss a dose.
• Tell your doctor and pharmacist about all other medicines and supplements you take.
• Do not change the dose or stop the medicine on your own. That is your doctor's decision.
• Report side effects to your doctor, your pharmacist or your national medicines agency.

Medication isn't everything - lifestyle matters

Now the part you have the most influence over: daily habits. Diet, exercise, sleep and quitting smoking matter whatever treatment your doctor recommends.

In type 2 diabetes, lifestyle change is part of the treatment, not an extra. Plan it with your doctor.

Diet - your first line of defence

What to eat?

• Non-starchy vegetables (broccoli, spinach, peppers) - as much as you want, practically unlimited
• Whole grain products (wholemeal bread, grains, brown rice) - in moderate amounts
• Lean protein (fish, poultry, eggs, legumes)
• Healthy fats (olive oil, nuts, avocado)
• Fruit - yes, but in moderation (berries, apples are better than bananas, grapes)

What to avoid?

• Sugar and sweets (cake, biscuits, milk chocolate)
• Sugary drinks (cola, juices, energy drinks)
• White bread, white rice, chips
• Fast food, processed meat
• Trans fats

The plate rule: Half your plate - vegetables. Quarter - protein. Quarter - whole grain carbohydrates. A spoonful of healthy fat.

Exercise - a prescription-free medicine

You don't have to run a marathon. Just 150 minutes of moderate activity per week is enough - that's 30 minutes a day, 5 days a week. A brisk walk, cycling, swimming, gardening - whatever you enjoy.

Why does it work? Exercise makes your muscles use glucose - blood sugar drops. Plus it improves cell sensitivity to insulin. It's like a natural medication.

Weight - every kilogram matters

If you are overweight or obese, losing even 5-10% of your body weight can noticeably improve diabetes control. Whether your treatment can then be changed is for your doctor to assess.

Stress and sleep

Chronic stress raises cortisol - and cortisol raises blood sugar. Lack of sleep has a similar effect. Aim for 7-9 hours of sleep, find ways to relax (meditation, hobbies, time with family).

Monitoring - knowledge is power

If you don't measure, you don't know. And if you don't know, you can't react.

Home blood glucose monitoring

Your glucose meter is your friend. How often to measure is something to agree with your doctor - it also depends on the medicines you take.

When to measure?

• Fasting (in the morning before breakfast)
• 2 hours after a meal (to see how your body handles food)
• Before bed (if your doctor recommends it)
• When you feel strange (could it be hypoglycaemia?)

What results are OK?

• Fasting: 80-130 mg/dl
• 2 hours after a meal: below 180 mg/dl

Your doctor may set different targets - it's an individual matter.

HbA1c - the gold standard

This is a blood test that shows your average blood sugar over the past 2-3 months. It's done every 3-6 months at a laboratory.

Targets:

• For most people with diabetes: below 7%
• For older adults, those with heart disease: below 8% (less strict)
• For younger people, without complications: below 6.5%

Most common questions (and honest answers)

Will I have to take medications for the rest of my life?

Not always. If you lose weight, change your diet and start moving, diabetes can go into remission. Whether you can reduce the dose or stop a medicine is decided only by your doctor.

What if I forget to take a tablet?

What to do after a missed dose is described in your medicine's package leaflet - the rules differ between medicines. If in doubt, ask your pharmacist.

Can I drink alcohol?

Alcohol affects blood sugar and can interact with diabetes medicines. Ask your doctor whether and how much you can drink. Your medicine's package leaflet also covers alcohol.

Where can I buy medications more affordably?

The diabetes medicines described above are prescription-only, and we do not compare prices of prescription medicines. On CheaperForDrug you can compare the price of a whole basket of non-prescription medicines and supplements, delivery included.

Can supplements help?

Food supplements are food, not medicines - they do not treat diabetes and they never replace medicines prescribed by your doctor. If you want to take one, ask your doctor or pharmacist first, as supplements can interact with medicines.

When to see a doctor immediately?

Call or go to the emergency department if:

• Blood sugar above 300 mg/dl and not dropping despite treatment
• Symptoms of ketoacidosis: abdominal pain, nausea, vomiting, acetone breath, rapid breathing
• Severe hypoglycaemia: loss of consciousness, seizures, inability to swallow
• Acute infections, fever above 38.5 degrees C
• Wounds that won't heal

Summary - what to remember?

Diabetes medicines are prescription-only - your doctor decides which one and at what dose. The full information is in the package leaflet.

There are several groups of medicines - knowing the group and substance names makes it easier to talk to your doctor and pharmacist.

Do not change the dose or stop medicines on your own - agree every change with your doctor.

Lifestyle is part of the treatment - diet, exercise and weight loss make a big difference.

Monitor your blood sugar regularly - at home with a glucometer, every few months with HbA1c. Knowledge is power.

Talk to your doctor and pharmacist - have doubts? Ask. It's your health, you have the right to know.

And remember: Diabetes is not the end of the world. It's a challenge that you can take on and win.
