Lanvis Adverse Reactions

For this product there is a lack of modern clinical documentation which can be used as support for determining the frequency of undesirable effects. LANVIS is usually one component of combination chemotherapy and consequently it is not possible to ascribe the side effects unequivocally to this drug alone.
The following convention has been utilised for the classification of frequency of undesirable effects: very common ≥1/10 (≥10%), common ≥1/100 and < 1/10 (≥ 1% and <10%), uncommon ≥1/1000 and <1/100 (≥0.1% and <1%), rare ≥1/10,000 and <1/1000 (≥0.01% and <0.1%), very rare <1/10.000 (<0.01%).
