Long back I had read an article that a
filarial leg could be treated with doxycycline 100 mg twice a day for 8 weeks with very good results. This is based on the theory that filaria need bacteria for their viability.
Since then, I have given this course to all the patients having this illness. I also give a course of Di-ethyl Carbamazine. I am not yet confident of prescribing doxycycline alone. Even if only the former drug is working, the results are far superior to those in the past.
By now I have seen dozens of cases of hydrocoele who have recovered without surgery, by taking only a course of Di-ethyl Carbamazine.
Since the cause of hydrocoele is yet unknown, I have started prescribing a course of doxycycline for two months to all patients, especially those who are not ready to undergo surgery. I am waiting for follow up results.
