This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- This medicine works best together with healthy eating, regular activity and keeping a healthy weight.
- It is for type 2 diabetes. It is not a replacement for insulin in type 1 diabetes.
- Tell your doctor if you have kidney, liver or heart problems.
- Tell your doctor if you are pregnant, planning a pregnancy or breastfeeding. Insulin is often used instead during pregnancy.
- Alcohol can affect your blood sugar. Drink only small amounts and never on an empty stomach.
- Learn the signs of low blood sugar (shaking, sweating, hunger, fast heartbeat, confusion) and keep sugary sweets or glucose tablets with you.
- Do not take it if you have inflammatory bowel disease, bowel blockage or severe kidney problems.
- For low blood sugar while on it with other diabetes medicines, use glucose (dextrose) tablets or gel, not ordinary sugar.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Glyset can cause side effects, but not everybody gets them.
Common side effects
- Wind (gas) and bloating
- Diarrhoea
- Stomach pain
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Signs of very low blood sugar that do not get better after eating sugar: confusion, drowsiness, fits or passing out
- Signs of an allergic reaction, such as swelling of the face or lips, a severe rash, or trouble breathing
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Take it three times a day, with the first bite of each main meal.
- Most people start with 25 mg three times a day and slowly increase to 50 mg three times a day.
- If you skip a meal, skip that dose.
If you miss a dose: If you forget to take it with a meal, skip that dose and take the next one with your next meal.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
- QWill I need to take Glyset forever?
- A
Type 2 diabetes is usually a long-term condition, so most people keep taking their medicine. Healthy changes to diet, activity and weight can sometimes reduce how much you need.
- QHow will I know if Glyset is working?
- A
Your doctor will check your blood sugar and HbA1c (an average of your blood sugar over about 3 months). Some people also check their sugar at home.
- QWhy must I take Glyset with the first bite of food?
- A
It needs to be in your gut at the same time as your food to slow down sugar absorption.
