Important information about gliclazide
Do not use more than the prescribed dose. Taking more medicine will not improve your symptoms; rather they can cause poisoning or serious side effects.
If you suspect that you or anyone else has overdosed on gliclazide, go to the nearest hospital or nursing home emergency department. Take a kit, container, or label with you to help doctors with the necessary information.
Do not give your medicines to other people, even if you know they have the same condition or it seems they may have similar conditions. This can lead to an overdose.
Consult your doctor or pharmacist or product package for more information.
Store medicines at room temperature, away from heat and direct light. Do not freeze medications unless required by the package insert. Keep medicines away from children and pets.
Do not flush medications down the toilet or pour them down the drain unless instructed to do so. Medication discarded in this way can pollute the environment. Please consult your pharmacist or doctor for more details on how to safely dispose of gliclazide.
A single expired dose of gliclazide is unlikely to produce an adverse event. However, talk to your primary healthcare provider or pharmacist for proper advice or if you feel unwell or ill.
Expired medication may become ineffective in treating your prescribed conditions. To be safe, it is important not to use expired medications.
If you have a chronic illness that requires constant medication, such as life-threatening heart conditions, seizures, and allergies, it is much safer to stay in contact with your primary healthcare provider so that you can have a fresh supply of unexpired medications.
How does gliclazide work specifically?
Gliclazide is a type of medicine known as a sulfonylurea. Sulfonylureas increase the amount of insulin made by the pancreas. Insulin is the hormone that controls the level of sugar in the blood.
When will I feel better?
You may not have had any symptoms of diabetes, so you won’t necessarily feel different when taking gliclazide. This does not mean that gliclazide is not working and it is important to keep taking it.
Gliclazide will help keep your blood sugar level stable and reduce your chances of future diabetes-related problems.
How long will I take gliclazide?
Treatment for diabetes is usually life-long. Do not stop taking your gliclazide tablets without consulting your doctor.
Can I take gliclazide for a long time?
Gliclazide is safe to take for a long time. There is no evidence that it harms your pancreas or your general health.
However, gliclazide may stop working properly after a while. Your doctor may want to stop it or add a different medicine to help keep your blood sugar stable.
What will happen if I suddenly stop taking gliclazide?
Do not stop taking gliclazide without consulting your doctor.
If you stop taking gliclazide suddenly, your diabetes may get worse.
Am I going to gain weight?
Gliclazide can make you hungrier and retain water, so it can be challenging to avoid gaining weight while taking it. Try to eat a healthy, balanced diet without increasing your portion sizes so you don’t gain too much weight. Regular exercise will also help keep your weight stable.
Are other diabetes medications better?
There are other groups of drugs that can lower blood sugar levels:
- DPP-4 inhibitors such as saxagliptin.
- SGLT2 inhibitors such as dapagliflozin.
- GLP-1 agonists as exenatide.
Gliclazide can be prescribed alone or in combination with the above medications.
It is usually prescribed if you cannot take metformin, or if metformin no longer keeps your blood sugar under control when used alone.
Gliclazide is a sulfonylurea. There are 4 other sulfonylureas available:
All of these work in the same way, by increasing the amount of insulin your body produces.
Can I take pain relievers with gliclazide?
It is safe to take acetaminophen with gliclazide.
Don’t take aspirin or ibuprofen – These pain relievers can interfere with gliclazide and lower your blood sugar levels too much.
Can I drive or ride a bike?
If your blood sugar levels are stable, your ability to drive, use bicycles, or use machines or tools should not be affected by gliclazide.
However, if your blood sugar levels drop too low, this can lower its concentration. If this happens to you, don’t drive, cycle, or use machines or tools until you feel better.
Do not drive or use machines or tools if you begin to feel symptoms of low blood sugar.
Will it affect my fertility?
Gliclazide does not affect male or female fertility.
Will it affect my contraception?
Gliclazide does not interfere with any type of contraception.
Some women may need to adjust their dose of gliclazide if they start taking the contraceptive pill. This is because birth control pills can occasionally raise blood sugar levels.
Can I drink alcohol with the medicine?
Yes, you can drink alcohol while taking gliclazide, but it is best for men and women to drink no more than 2 units per day. Drinking more than this can increase the risk of hypoglycemia.
Usually a standard wine glass or beer can is 2 units.
Are there any foods or drinks that I should avoid?
It is a good idea to cut down on foods with added sugar. Check nutrition labels as many foods and drinks are high in sugar, such as:
- Some fizzy drinks.
- Karela (also called bitter gourd) is used to flavor foods such as curries, such as bitter gourd masala. It has a bitter taste and is also made into juice and tea.
Be careful eating foods and drinks that contain karela, as they can lower blood sugar levels and your diabetes is not controlled as well as it should.
Can I take gliclazide before having surgery?
If you are going to have an operation, tell your doctor that you are taking gliclazide.
This is because gliclazide increases the risk of hypoglycaemia during the operation. Low blood sugar can be difficult to detect when using a general anesthetic (which puts you to sleep).
For a few days, around the time of the operation, your doctor may temporarily switch you to insulin.
Can lifestyle changes help my diabetes?
There are some lifestyle changes you can make to help manage your diabetes symptoms.
- Eating a healthy diet.
- Lose any excess weight
- No Smoking.
- Do not drink too much alcohol, specifically it is recommended no more than 2 units per day.
- Exercising regularly, up to 30 minutes a day, 5 times a week is ideal.
