• In clinical trials involving 22,757 subjects, a total of 644 patients (2.83%) showed adverse reactions including abnormal laboratory values. The following summary of data includes adverse reactions reported after marketing without incidence rates (Figures are tota
l cases reported at the time of approval of the initial application, completion of reexamination, and approval of an additional indication for the oral formulations: Meptin® 25 mcg/ 50 mcg tablet, Meptin® syrup).
Clinically significant adverse reactions (*incidence unknown)
1. Shock, anaphylactoid reaction: Shock or anaphylactoid reaction may occur. Patient should therefore be closely monitored. If abnormal findings are observed, the drug should be discontinued and appropriate measures taken.
2. Significant decreases in serum potassium levels have been reported in patients receiving procaterol hydrochloride. If xanthine derivatives, corticosteroids, or diuretics are co-administered with this drug in patients with severe asthma, extreme care is necessary to minimize the possibility of aggravating the decrease in serum potassium levels induced by ß2-adrenergic agonists. Serum potassium levels should be closely monitored in hypoxic patients, in view of the possible aggravation of cardiac arrhythmias secondary to a decrease in serum potassium levels.
Use during Pregnancy, Delivery or Lactation
1. The drug should be administered to pregnant or possibly pregnant women only if the expected therapeutic benefit is thought to outweigh any possible risk. (The safety of this drug during pregnancy has not been established).
2. Nursing should be interrupted before starting treatment with the drug. (Rat studies showed that procaterol hydrochloride is excreted in breast milk).
