Why have I been prescribed Diaglyc?

What are the possible risks or side-effects?

Common side effects include:

Treatment with Diaglyc MR 30 mg can cause hypoglycaemia, if mealtimes are irregular and, in particular, if meals are skipped.

Possible symptoms of hypoglycaemia are:

  • headache
  • intense hunger
  • nausea
  • vomiting
  • lassitude
  • sleep disorders
  • agitation
  • aggression
  • poor concentration
  • reduced awareness and slowed reactions
  • depression
  • confusion
  • visual and speech disorders
  • aphasia
  • tremor
  • paresis
  • sensory disorders
  • dizziness
  • feeling of powerlessness
  • loss of self-control
  • delirium
  • convulsions
  • shallow respiration
  • bradycardia
  • drowsiness and loss of consciousness, possibly resulting in coma and lethal outcome

In addition, the following may be observed:

  • sweating
  • clammy skin
  • anxiety
  • racing heart
  • hypertension
  • palpitations
  • angina pectoris
  • cardiac arrhythmia

Usually, symptoms disappear after intake of carbohydrates (sugar). However, artificial sweeteners have no effect. Hypoglycaemia can recur even when measures prove effective initially.
If a hypoglycaemic episode is severe or prolonged, and even if it is temporarily controlled by intake of sugar, immediate medical treatment or even hospitalisation are required.
Gastrointestinal disturbances, including abdominal pain, nausea, vomiting, dyspepsia, diarrhoea, and constipation have been reported: if these should occur they can be avoided or minimised if Diaclide is taken with breakfast.

Can I drink alcohol while taking it?

You should not drink alcohol while taking Diaglyc.

What if I’m pregnant/breastfeeding?

  • It is recommended that oral therapy is changed to insulin before a pregnancy is attempted, or as soon as pregnancy is discovered.
  • Diaglyc cannot be given while breast feeding.
