What this medicine is for

Intramuscular benzathine penicillin is indicated in the treatment of infections due to penicillin-sensitive micro-organisms that are susceptible to the low and very prolonged serum levels common to this particular dosage form. Therapy should be guided by bacteriological studies (including sensitivity tests) and by clinical response. The following infections will usually respond to adequate dosage of intramuscular benzathine penicillin: Streptococcal infections (Group A - without bacteraemia). Mild-to-moderate infections of the upper respiratory tract (e.g. pharyngitis). Venereal infections - Syphilis, yaws, bejel and pinta. Medical conditions in which benzathine penicillin therapy is indicated as prophylaxis: Rheumatic fever and/or chorea - Prophylaxis with benzathine penicillin has proven effective in preventing recurrence of these conditions. It has also been used as a follow-up prophylactic therapy for preventing rheumatic heart disease and acute glomerulonephritis.
