The following summary of data includes adverse reactions reported after marketing without incidence rates.
Clinically Significant Adverse Reactions (*Incidence Unknown): Shock, Anaphylactoid Reactions: Shock or anaphylactoid reactions may occur. Patients should therefore be closely monitored. If abnormal findings are observed, Meptin should be discontinued and appropriate measures taken.
Significant decreases in serum potassium levels have been reported in patients receiving Meptin. 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 β2-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.
Other Adverse Reactions: The following table shows the adverse reactions for tablets: (see Table 1).

The following table shows the adverse reactions for syrup: (see Table 2).
