7	Reproductive toxicity	Category 2,	Warning	H361 H362	P308+P313 P201 P202 P260 P263 P264 P270 P280 P405 P501	[Rationale for the Classification] Based on (1)-(3), it was classified in Category 2. In addition, based on (4), "additional category for effects on or via lactation" was added to the classification. [Evidence Data] (1) In a teratogenicity test with rats by the oral route, cardiovascular anomalies were observed in the fetuses at the highest dose where maternal toxicity (unknown details) was observed (Pharmaceutical Interview Forms (April, 2019 (23rd edition)), HSDB (Access on September 2019)). (2) In a teratogenicity test with mice by the oral route, cleft palate was observed in the fetuses at the highest dose where maternal toxicity (unknown details) was observed (Pharmaceutical Interview Forms (April, 2019 (23rd edition)), HSDB (Access on September 2019)). (3) It is described that in animal experiments, since fetotoxicities (abnormalities in the cardiovascular system, cleft palate, growth retardation, etc.) were reported at the high doses where toxicity was manifested in maternal animals, it should be administered to pregnant women or women who may be pregnant only when the benefit exceeds the risk (Ethical Pharmaceuticals 2017 (2016)). (4) Since it is reported that this substance will pass into breast milk, nursing women should avoid breast feeding during treatment. Besides, there is a description that concentrations in milk in an animal experiment (rats) remained about 2.5 times higher than those in the blood (Ethical Pharmaceuticals 2017 (2016)).

8	Specific target organ toxicity - Single exposure	Category 1 (gastrointestinal tract, liver)	Danger	H370	P308+P311 P260 P264 P270 P321 P405 P501	[Rationale for the Classification] This substance is a macrolide antibiotic drug, and it is pharmaceutically used for the treatment of various bacterial infections by oral administration. Based on (1), it was classified in Category 1 (gastrointestinal tract, liver). The increase in eosinophil was not adopted as evidence since there is a possibility of changes due to hypersensitivity, etc. [Evidence Data] (1) Although the number of doses was unknown, as major side effects, symptoms of the blood system (increased eosinophil count), liver (elevated AST and ALT) and gastrointestinal tract (nausea, vomiting, gastric discomfort, abdominal distension, abdominal pain, diarrhea) were observed at frequencies of 0.1 to <5% (Ethical Pharmaceuticals 2017 (2016)). [Reference Data, etc.] (2) As for serious side effects (frequencies unknown for all), there are reports of QT prolongation, ventricular tachycardia (including Torsades de pointes) or ventricular fibrillation, fulminant hepatitis, liver dysfunction, jaundice or hepatic failure, decreases in platelets and pancytopenia, hemolytic anemia, leukopenia or agranulocytosis, PIE syndrome, interstitial pneumonia, pseudomembranous colitis or hemorrhagic colitis, rhabdomyolysis, convulsions, and acute nephropathy or tubulointerstitial nephritis (Ethical Pharmaceuticals 2017 (2016)).

9	Specific target organ toxicity - Repeated exposure	Category 1 (gastrointestinal tract, liver)	Danger	H372	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on (1), the main side effects by repeated administration of this formulation were observed in the gastrointestinal tract and liver. Therefore, it was classified in Category 1 (gastrointestinal tract, liver). As for the increased eosinophils, it was not adopted as evidence due to possible changes due to hypersensitivity, etc. [Evidence Data] (1) As for information on side effects for patients with general infectious diseases, out of a total of 3,894 cases (2,885 for adults and 1,009 for children) at the time of approval, side effects were observed in 96 cases for adults (3.33%) and 21 cases for children (2.08%), and 117 cases for a total (3.00%). The main types of side effects were gastrointestinal symptoms such as abdominal pain and diarrhea. There is a report that increased ALT and AST, and increased eosinophil count were the main changes in laboratory values (Ethical Pharmaceuticals 2017 (2016)). [Reference Data, etc.] (3) As for serious side effects (frequencies unknown for all), there are reports of QT prolongation, ventricular tachycardia (including Torsades de pointes) or ventricular fibrillation, fulminant hepatitis, liver dysfunction, jaundice or hepatic failure, decreases in platelet, pancytopenia and hemolytic anemia, leukopenia or agranulocytosis, PIE syndrome, interstitial pneumonia, pseudomembranous colitis or hemorrhagic colitis, rhabdomyolysis, convulsions, and acute nephropathy or tubulointerstitial nephritis (Ethical Pharmaceuticals 2017 (2016)).
