Is 400 Mg Of Zentel For 3 Days Sufficient For Round Worms?

Good morning Dr. Is there anything like overdose of zentel? I am asking because my lab scientist said my result shows I have round worm. It s been a longtime, like a year, since I have been having pain around my lower abdomen, some times on my back, some times around the ribs. And with recurrent fever, have been switching between malaria and typhoid treatment until I recently went for test, and round worm was confirmed. Since the signs have been there for a long time, don t it mean the worms have been there for a long time doing some damages? Do you feel 400mg by 3 days will still be sufficient? I feel like I should take more
