Recurrent Of Parasitic infection/Infest.

I am having recurrent parasitic infection for the last 6 months and I have taken vermox( 100 mg * 2 Times for 3 days ), albendazole 400 mg ( 1 Tab day 1, second Tab day 7 , third Tab day 30 ) , pyrantel Pamoate liquid Suspension, albendazole 400 mg ( 1 Tab day 1, second Tab day 14 , third Tab day 30 ) . Capsule endoscopy revealed the presence of parasites in the small intestines. during these 6 months and still have symptoms, especially, with anal itching at night. They just vanished whenever I take albendazole but after 2-3 weeks it comes back. Can someone please help? Some have advised to check homeopathic/ Ayurvedic treatment, instead of allopathic treatment which give temporary results. Pls help
