Semaglutide is used to treat type 2 diabetes (a long-term condition in which the body gradually becomes resistant to the effects of insulin or the pancreas does not produce enough insulin).
This medicine helps treat your diabetes by keeping your blood sugar under control.
Semaglutide is meant to be taken as part of a complete diabetes care programme that should include exercise, a healthy diet and regular monitoring of blood sugar levels.
Take Semaglutide exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
Take it on an empty stomach, at least 30 minutes before the first food, beverage or oral medicine of the day. Try to take it at the same time each day.
Swallow the tablet whole with a sip of water (up to a half glass or about 120 mL of water). Do not divide, chew or crush the tablet.
Semaglutide must be taken regularly for it to be effective. Continue taking this medicine even when you feel better. Do not stop taking it unless instructed by the doctor.
If you miss a dose, skip the missed dose and return to your normal dosing schedule.

For as long as you are taking this medicine, you will need to have regular blood tests (e.g. blood sugar level, cholesterol level, kidney function) to check your body's response to the medicine. Your doctor will advise you about how often you need to have these tests.
To help control your diabetes, it is important to continue following the diet and exercise recommended by your doctor while you are taking Semaglutide.
If you are taking this medicine with other types of anti-diabetic medicines, you may have been warned about hypoglycaemia (low blood sugar).
How do I know if I am experiencing hypoglycaemia?
Hypoglycaemia is the medical term for low blood sugar. Symptoms of hypoglycaemia include dizziness, tremor, shaky hands, feeling hungry, weak or confused, and sweating. These signs are your body's way of warning you that your blood sugar level is low.
It is important to recognise these symptoms and get relief for hypoglycaemia quickly, as the hypoglycaemia may worsen.
What should I do if I am experiencing hypoglycaemia?
Always carry some glucose tablets (also known as dextrose tablets) with you. Take 15 grams of glucose tablet at first sign of hypoglycaemia, wait for 15 minutes and re-check your blood sugar level. If you are not feeling better or if your blood sugar level is still low (less than 4 mmol/L or 70 mg/dL), take another 15 grams of glucose tablet.
If you don't have glucose tablets, you may take any of the following:
- 1/2 cup (120 mL) of juice or regular soda (not diet)
- 1 tablespoon of sugar, honey, or corn syrup
- hard candies, jellybeans, or gumdrops (not sugar-free)
Get medical help should symptoms not improve after the second serving.
