Product information

Onglyza is a medication used to treat type-2 diabetes, and works by limiting the effect of enzymes which counteract the production of insulin. It is a once a day tablet, and is designed to be used alongside a controlled diet and exercise programme to help reduce blood sugar. AstraZeneca are the manufacturers of Onglyza, which is available to buy in the UK in two separate doses: 2.5 and 5mg. The dose you are issued will depend on your blood sugar levels, and whether or not you are currently using other prescription medicine.

  1. Helps to regulate blood sugar
  2. Taken in addition to a diet and exercise regime
  3. Basic one a day tablet

Diabetes is a condition where blood sugar levels rise to a point which may, over time, cause significant damage to the nervous system, organs or blood vessels. There are several different types, but the most common is type-2 diabetes. This version may not develop until a person has reached their 40s, unlike type-1 diabetes which typically becomes apparent during a person’s formative years.

Initially, the condition will only present mild, non-specific and often unnoticeable symptoms such as tiredness, an increased need to pass urine, and a feeling of dryness in the eyes, potentially causing sight problems. However, left untreated, complications may result and, in severe cases, lead to heart disease or organ failure.

Several diet and lifestyle factors can increase a person’s chances of getting type-2 diabetes. These include eating a poor or unhealthy diet, being overweight or obese, and not getting enough exercise. As well as being more prevalent in those over the age of 40, it is also more likely to affect people of South Asian or Chinese, or Black African or Caribbean ethnicity.

The condition is a progressive one, which makes seeking diagnosis and treatment if you think you have it crucial. One of the first measures a doctor will take to help the patient get their blood sugar levels under control will be to introduce a healthier eating regimen. They may also suggest a programme of light exercise.

However, those who are not able to bring their blood sugar levels down to normalcy through these means alone may need to be issued prescription medication. One such option is Onglyza, which is a type of drug called a DPP-4 inhibitor. It may be administered in addition to other forms of treatment, such as biguanides or insulin, but it can also be used as a sole medication in some cases.

Saxagliptin is the name of the functioning constituent, which works by stopping the enzymatic breakdown of glucagon-like peptide-1 and glucose insulinotropic peptide, otherwise known as GLP-1 and GIP respectively. Both of these hormones stimulate the pancreas to produce insulin after the consumption of food; while GLP-1 also helps to limit the production of sugar by the liver. In preserving the presence of the hormones, the drug thereby assists in the production of insulin and management of blood sugar levels.

We do not currently sell this medication on our site. To be prescribed Onglyza or renew your prescription, we recommend you make an appointment with your doctor or diabetes nurse.
