i see. What was your dosage and how many times a day did you take albendazole in 2012 and in 2014? Also, how many cycles did you try for each? ICU said albendazole only kills adult roundworms and not the adults of other worms (it kills larvae, eggs of other worms tho). So it may be that in 2012 you didn't have roundworms, but in the 2014 you did.
Also, what symptoms did/do you have? how did you know so quickly after contraction that you had a parasite? (it usually takes years if not decades for people to realize it is parasitic infection that causes their symptoms because symptoms from parasitic infections happen develop very gradually. Also, are you constipated? Constipation often is due to the common roundworms and other large roundworms.
