Adverse Reactions
Fornidd: Gastrointestinal symptoms such as nausea, vomiting, diarrhoea, abdominal pain and loss of appetite (>10%) are very common: these occur most frequently during initiation of therapy and resolve spontaneously in most cases. To prevent these gastrointestinal symptoms, it is recommended that metformin be taken 2 or 3 daily doses during or after meals. A slow increase of the dose may also improve gastrointestinal tolerability.
Metallic taste (3%) is common.
Mild erythema has been reported in some hypersensitive individuals. The incidence of such effects is regarded as very rare (<0.01%).
A decrease of vitamin B12 absorption with decrease of serum levels has been observed in patients treated long-term with metformin and appears generally to be without clinical significance (<0.01%).
Lactic acidosis (0.03 cases/1000 patients-years) is very rare (see Warnings and Precautions).
Blood and lymphatic system disorders: Not known: Reduction of thyrotropin level in patients with hypothyroidism, hypomagnesemia in the context of diarrhea.
Nervous system disorder: Not known: Encephalopathy.

Dermatological Effects: Rash, pruritus, urticaria, erythema and flushing.
