This is an educational overview, not advice. Your medication is between you and your doctor.
That said: it helps to know what you are taking, and why. Here is the menu in plain English.
Metformin
First-line for Type 2 in almost everyone. Reduces liver glucose output, makes cells more insulin-sensitive. Low cost, very safe long-term, mild weight benefit, low hypo risk. Common side effect: stomach upset, usually resolves in 2-3 weeks. Take with food.
Sulfonylureas (glimepiride, glipizide)
Push the pancreas to make more insulin. Effective and cheap but carry hypo risk and slight weight gain. Older class — newer options often preferred.
DPP-4 inhibitors (sitagliptin, vildagliptin)
Help your gut release more of its own insulin after meals. Weight-neutral, low hypo risk, well-tolerated. Modest effect on A1c.
GLP-1 agonists (semaglutide, liraglutide, tirzepatide)
The class that is changing diabetes care. Injectable (some now oral). Powerful A1c reduction, significant weight loss, cardiovascular protection, slows stomach emptying. Side effect: nausea early on. More expensive.
SGLT2 inhibitors (empagliflozin, dapagliflozin)
Make the kidneys flush extra sugar into urine. Weight loss, blood-pressure lowering, strong heart and kidney protection. Watch for urinary tract infections, dehydration.
Insulins
Many types: rapid, short, intermediate, long-acting, mixed. Used in Type 1 always, Type 2 when other meds are not enough or in specific situations (pregnancy, surgery, kidney issues). Modern insulin pens make injection nearly painless. Hypo is the main risk — understand the symptoms.
Important reminders
- Never stop a medication without talking to your doctor
- Don't skip doses to "save" medicine — tell your doctor about cost constraints
- Some meds interact with each other — always show your full list
- Diabetic ketoacidosis (DKA) risk rises if you stop insulin or skip SGLT2 doses when sick
- Pregnancy, planned surgery, or starting a new med? Tell your doctor about your full diabetes picture
