Medication - Metformin Xr (Glucophage Xr) 500 Mg (1 tablet)

Metformin XR usually does not cause a glucose rise on its own; review what you ate or drank with the dose, missed doses, illness, stress, and glucose-sensor timing before changing anything.

Take Glucophage XR exactly as prescribed, usually with a meal, and swallow the tablet whole; do not split, crush, or change the timing/dose without your prescriber’s advice.

For meals around the dose, prioritize protein, non-starchy vegetables, and slower-digesting carbohydrates such as lentils, chickpeas, beans, steel-cut oats, or plain Greek yogurt, while limiting sugary drinks and refined starches.

If by “negative spike” you mean low glucose, confirm it with a finger-stick test if possible. Treat significant symptoms or a reading below 70 mg/dL (3.9 mmol/L) promptly with fast-acting carbohydrate and seek urgent help for confusion, fainting, seizure, or inability to swallow.

Keep a log for several days of dose time, meals, activity, symptoms, and glucose readings; share it with your clinician or pharmacist to identify a consistent pattern.

Contact your prescriber promptly if repeated unusual readings occur, especially if you also use insulin or medicines such as gliclazide, glipizide, or glyburide, since these can increase the chance of low glucose.
