Diabetes Medications

Oral medications

Metformin

This is the most commonly used medication for diabetes; it helps the body to use the insulin you are producing to work better. It is normally in tablet form. Metformin is best taken as you sit down to eat your meal or directly after your meal. When first starting metformin, it may cause gastric side effects such as feeling bloated or diarrhoea; this is why metformin is started gradually. If your symptoms continue, contact your GP as you may need a modified release version.

SGLT2 inhibitors

These medicines work in the kidney, helping excess sugar pass out of the body in your urine. This can help your blood sugar levels become lower. You may experience some weight loss after starting these tablets. It is important to keep well hydrated by drinking plenty of fluids.

Side effects can include genital thrush or urine infections. If this happens, speak to your doctor for treatment as it can be easily treated. It is possible you could get dehydrated because of how the drug works - signs include a fast heartbeat, very dry or sticky mouth, feeling very thirsty, very sleepy or tired, or passing little or no urine.

When you are unwell, you are at increased risk of developing Diabetes Ketoacidosis (DKA) – you can find out more about this in the relevant leaflet below.
