“…It has been estimated that some side effects arise in 0.4% of subjects receiving S-T, and this probably occurs in about 1% of cases. Rashes constitute 60% of side effects, while the most significant adverse effects reported are agranulocytosis or aplastic anaemia which are, however, reversable when the drug is discontinued (Schofield et al, 1969). The particular advantage of S-T is not only its wide spectrum of antibacterial activity, but also the prolonged period of excretion in the urine after oral administration.…”
