Adverse effects are classified by frequency and by system organ class (SOC). Frequency is defined according to the following convention: very frequent (≥ 1/10), frequent (≥ 1/100, < 1/10), uncommon (≥ 1/1 000, < 1/100), rare (≥ 1/10 000, < 1/1 000), very rare (< 1/10 000), unknown frequency (cannot be estimated on the basis of available data).
