Diamicron/Diamicron MR 60 Adverse Reactions

Based on the experience with gliclazide, the following undesirable effects have been reported.
Hypoglycemia: The most frequent adverse reaction with gliclazide is hypoglycemia.
As for other sulfonylureas, treatment with Gliclazide (Diamicron) can cause hypoglycemia, in particular if mealtimes are irregular and if meals are skipped.
Possible symptoms of hypoglycemia 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, signs of adrenergic counter-regulation may be observed: sweating, clammy skin, anxiety, tachycardia, hypertension, palpitations, angina pectoris and cardiac arrhythmia.
Usually, symptoms disappear after intake of carbohydrates (sugar). However, artificial sweeteners have no effect. Experience with other sulfonylureas shows that hypoglycemia can recur even when measures prove effective initially.
If a hypoglycemic episode is severe or prolonged, and even if it is temporarily controlled by intake of sugar, immediate medical treatment or even hospitalization are required.
Other undesirable effects: Gastrointestinal disturbances, including abdominal pain, nausea, vomiting, dyspepsia, diarrhea, and constipation have been reported: if these should occur they can be avoided or minimized if gliclazide is taken with a meal or by splitting the doses.
The following undesirable effects have been more rarely reported: Skin and subcutaneous tissue disorders: rash, pruritus, urticaria, angioedema, erythema, maculopapular rashes, bullous reactions (such as Stevens-Johnson syndrome and toxic epidermal necrolysis), and exceptionally, drug rash with eosinophilia and systemic symptoms (DRESS).
Blood and lymphatic system disorders: changes in hematology are rare. They may include anemia, leucopenia, thrombocytopenia, granulocytopenia. These are in general reversible upon discontinuation of medication.
Hepato-biliary disorders: raised hepatic enzyme levels (AST, ALT, alkaline phosphatase), hepatitis (isolated reports).
Discontinue treatment if cholestatic jaundice appears.
These symptoms usually disappear after discontinuation of treatment.
Eye disorders: transient visual disturbances may occur especially on initiation of treatment, due to changes in blood glucose levels.
Class attribution effects: As for other sulfonylureas, the following adverse events have been observed: cases of erythrocytopenia, agranulocytosis, hemolytic anemia, pancytopenia, allergic vasculitis, hyponatremia, elevated liver enzyme levels and even impairment of liver function (e.g. with cholestasis and jaundice) and hepatitis which regressed after withdrawal of the sulfonylurea or led to life-threatening liver failure in isolated cases.
Diamicron MR 60: Skin and subcutaneous tissue disorders: autoimmune bullous disorders.
Reporting of Adverse Drug Reaction: Seek medical attention immediately at the first sign of any adverse drug reaction.
