Description of intervention(s) / exposure
This is a Phase II trial to test the safety, tolerability, acceptance, and pharmaco-equivalence of high dose subcutaneous Bicillin® L-A in children and young adults living with rheumatic fever and regularly receiving intramuscular benzathine penicillin G (BPG) injections. 70 to 91 days after the participants have taken part in ACTRN12622000916741, they will be offered the opportunity to remain on high dose (11.5mL/13.8MIU-20.7mL/10.8MIU) subcutaneous injection of Bicillin® L-A as an alternative to their regular monthly intramuscular BPG injection. Subcutaneous injection of high dose Bicillin, will be administered by the study nurse every 70-91 days for a period of 18 months. Electronic medical records will be utilised to monitor adherence to the high dose Bicillin.
