Glucophage is a treatment used to help those with diabetes control their blood sugar levels. It is available in three forms: as a standard tablet; a powder which is made up into a drinkable solution; and as a slow-release tablet. The drug contains an agent called metformin, which is a type of antidiabetic called a biguanide, and helps the body to produce and utilise insulin. In the UK, you will need a prescription in order to be able to buy Glucophage from a pharmacy. This will need to be issued by a practising doctor.

Type 2 diabetes accounts for an estimated 90 per cent of all cases of diabetes in the UK, which is thought to total over 3 million. It is characterised by an inability to produce amounts of insulin adequate enough to manage high blood sugar levels; or a failure by cells in the body to sufficiently extract glucose from the blood. This can cause various symptoms, but the most common among these are: dryness in the eyes, leading to sight problems; urinary urgency or an increased need to go to the toilet; and feelings of tiredness.
Numerous risk factors can contribute towards type 2 diabetes which, unlike type 1 diabetes (an autoimmune condition which develops early on in life) is more likely to occur the older a person gets. These include being overweight, and eating an unhealthy diet. People from certain ethnic backgrounds, such as those who are of South Asian or Chinese origin, or Black African or Caribbean descent, are also more likely to develop the condition.
It is important to seek treatment for diabetes as early as possible as it is progressive in nature. Complications which can arise from the condition include heart disease, kidney failure and nerve damage. During earlier stages, a doctor may suggest taking a number of non-medicinal approaches in order to get blood sugar levels under control. These include stopping smoking and lowering alcohol intake, and losing weight; they may advise adopting a specific diet, which might be accompanied by a balanced programme of exercise.
At a certain stage however, treatment may be required to help manage the illness. The active constituent of Glucophage is metformin, which is a type of drug called a biguanide. It works in three ways to help keep blood sugar levels in check: by reducing the amount of glucose produced by the liver; by increasing the body’s muscular cell receptiveness to insulin, thereby enabling more sugar to be extracted from the blood; and by inhibiting the absorption of sugars from food through the intestine.
Merck Serono is the company which manufactures all three forms of Glucophage, and markets them for purchase in the UK.
