Hello and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. There is no pill by which fracture will get heal soon. Lower limb fracture takes one month to one and half month to heal if treated conservatively. For faster healing operation has to be performed (open reduction and internal fixation). Only certain factors like calcium intake, taking rest helps in proper healing of fracture. Rifampicin is a drug which is used to treat tuberculosis not fracture. You may do weight bearing exercises once your fracture heals for better strength of healed part and early return to your active life. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Harsh Swarup
