Side effects

The frequency of side effects of the drug is rated as follows: very frequently (≥1/10); frequently (≥1/100, <1/10); infrequently (≥1/1000, <1/100); rarely (≥1/10000, <1/1000); very rarely (<1/10000).

The side effects are presented in decreasing order of importance.

Metabolism and nutrition: very rare – lactoacidosis (see “Special Precautions”). With prolonged use of metformin a decrease in absorption of vitamin B12 may be observed. If megaloblastic anemia is detected, the possibility of this etiology should be considered.

Nervous system disorders: often – disorders of taste.

Gastrointestinal tract: very often – nausea, vomiting, diarrhea, abdominal pain, lack of appetite. They occur most frequently during the initial period of treatment and in most cases disappear spontaneously. To prevent symptoms, it is recommended that metformin be taken 2 or 3 times daily with or after meals. Slowly increasing the dose may improve gastrointestinal tolerance.

Skin and subcutaneous tissue disorders: very rare – skin reactions such as erythema, pruritus, rash.

Liver and biliary tract disorders: very rare – liver dysfunction or hepatitis; these adverse events disappear completely after cancellation of metformin.

Published data, post-marketing data, and controlled clinical trials in a limited pediatric population in the 10-16 year age group show that side effects are similar in nature and severity to those in adult patients.
