Dietary advice
This medicine may cause episodes of low blood sugar (hypoglycaemia). This is more likely if:
- you are on a strict diet,
- your diet is poorly balanced,
- you are taking prolonged or strenuous exercise,
- you drink alcohol,
- you are taking several medicines for high blood sugar (See Other medicines and Diamicron 80mg).
If you have low blood sugar you may have the following symptoms: headache, intense hunger, nausea, vomiting, weariness, sleep disorders, restlessness, aggressiveness, poor concentration, reduced alertness and reaction time, depression, confusion, speech or visual disorders, tremor, sensory disturbances, dizziness, and helplessness.
The following signs and symptoms may also occur: sweating, clammy skin, anxiety, fast or irregular heart beat, high blood pressure, sudden strong pain in the chest that may radiate into nearby areas (angina pectoris).
If blood sugar levels continue to drop you may suffer from considerable confusion (delirium), develop convulsions, lose self control, your breathing may be shallow and your heart beat slowed down, you may become unconscious. In most cases the symptoms of low blood sugar vanish very quickly when you consume some form of sugar, for instance glucose tablets, sugar cubes, sweet juice, sweetened tea. You should therefore always carry some form of sugar with you (glucose tablets, sugar cubes). Remember that artificial sweeteners are not effective.
Please contact your doctor or the nearest hospital if taking sugar does not help or if the symptoms recur.
