More information about Metformin

What is Metformin?

Metformin (also sold under the brand name Glucophage) is a medication prescribed for the management of type-2 diabetes.

Metformin reduces the amount of sugar released by your liver and improves the way your body handles insulin - the hormone produced by the pancreas that regulates blood sugar.

It is usually prescribed as 500mg or 850mg standard-release tablets (available to buy from HealthExpress in 84 or 168 pill packages). However, you may be recommended a modified-release (MR) version (in 500mg, 750mg and 1000mg dosages).

Your doctor will determine which is the best option for you. You should first be diagnosed with diabetes and prescribed treatment by a regular doctor before you can buy Metformin online.

You should combine this treatment with a healthy diet and exercise routine.

Please note, this medication is only prescribed for type-2 diabetes. If you suffer from type-1 diabetes, please consult your doctor for other treatment.

How does it work?

Diabetes is a common metabolic condition that causes high blood sugar levels. It can result in symptoms like excessive thirst and hunger, fatigue and frequent urination and cause serious complications if left untreated.

Metformin contains the active ingredient metformin hydrochloride. As a biguanide medication, it helps your body respond more effectively to the hormone insulin that is produced by the pancreas. It could be that you produce less insulin or that you have grown insensitive to its effects.

Simultaneously, Metformin also reduces the amount of glucose that is produced by the liver.

These combined effects aid your body in regulating blood sugar levels.

When taking this medication, it is important to also maintain a healthy diet and exercise frequently.

How do I take it?

Always take medication exactly as it has been prescribed to you. If you are uncertain about any instructions, consult the patient information leaflet (PIL) or contact your doctor.

When taking any version of Metformin:

  • you should not exceed the prescribed daily dosage
  • you should take each tablet with food
  • take tablets whole - do not crush or break them
  • you should visit your doctor regularly to have your blood sugar levels and your kidney function tested
  • this medication should not be used as a substitute for an exercise and diet regime
  • if you forget to take a dose, do not take a double dose - continue the course as normal

Standard-release (SR)

If you have been prescribed a single dose, take it in the morning with breakfast.

If you have been prescribed two daily doses, take one in the morning with breakfast and a second in the evening with dinner.

If you have been prescribed three daily doses, take one in the morning with breakfast, second in the afternoon with lunch, and a third in the evening with dinner.

Modified-release (MR)

Generally, you will be prescribed one modified-release tablet a day. If this is the case, you should take it in the evening with dinner.

However, you may be prescribed two tablets a day. In this situation, follow the advice of your doctor for when to take them.

What are the possible side effects?

Though not everybody taking Metformin will suffer side effects, the following are the most commonly occurring:

  • abdominal pain
  • decreased appetite
  • diarrhoea
  • stomach issues
  • nausea
  • altered-taste
  • vomiting

For a complete list, please read the patient information leaflet (PIL) that will be included with your order.

If any side effects cause too much discomfort or persist for a long time, you should talk to your doctor to discuss alternatives.

You should also stop taking this medication and seek immediate medical attention if you suspect you are experiencing an allergic reaction.

What precautions should I take?

When taken correctly, and according to your prescribing doctor’s instructions, Metformin is a safe and effective medication. Nonetheless, there are certain groups of people who should exercise particular caution. This may be due to secondary health issues or potential interactions with other treatments.

If any of the following apply to you, do not take Metformin:

  • you have severe kidney or liver problems
  • you have uncontrolled diabetes
  • you have a severe infection
  • you have a severe heart condition or have had a heart attack recently
  • you suffer from alcoholism
  • you are pregnant or breastfeeding
  • you have diabetic ketoacidosis
  • you are allergic to any of this treatment’s ingredients
  • you take beta-blockers (e.g. propranolol, metoprolol, and glaucoma eye drops)

If you are ineligible to order this medication, you should speak to your doctor about other treatments.

If at any point while taking this treatment you need to have a scan (e.g. CT) that requires a dye to be injected into your bloodstream, then you will need to stop taking Metformin temporarily so that your kidneys are not affected.

Alcohol consumption should be avoided whilst using this treatment. This is because it can significantly increase the risk of hypoglycaemia and lactic acidosis.

It is important to stick to a diet and exercise regime. Metformin is only used to control blood sugar and is therefore not a substitute for eating healthily and exercising.

Your doctor may want to check your kidney function when taking Metformin tablets, normally once or twice a year. If you are elderly, these checks will be more frequent.

The shells of the pills may occasionally pass through your gut and appear visible in your stool - this is completely normal.
