Hi,
Usually, the treatment for
filaria is given for 12 days with banocide in a dose of 6mg/kg/day. Alternatively, the treatment with doxycycline can be given with a dose of 200mg/day for 6 weeks. As you have been given treatment combined with both these drugs, your doctor might have thought it necessary to go for it, as it may be necessary in some cases.
As, your treatment seems effective, as you say that swelling has reduced to 30% with 3 days treatment. Hence, in my opinion, you should complete the treatment, as advised by your doctor (which may be 12 days of Banocide and 6 weeks of doxycycline). Hope your problem gets resolved with complete treatment. However, even if, after complete treatment, if you get some problem or the disease appears again, then you are advised to see your doctor and treatment done accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Satnarain Bansal, General & Family Physician
