Hi Doctor. I Am 33 Years Old Man. When I
Doses need to be calculated according to individual needs.
I understand your concern.
Before advising drug for worm infestation, it's necessary to ascertain the type of worm infestation ...because the dosage of the drug depends on the type of worm infestation.
Thinking of life history of worms and considering symptom of anal itching you have...(no history of blood in stools, big roundworm being passed)...I guess it's Threadworm.
The drug commonly used is for the worm is Albendazole. The dose is calculated by considering the patient's weight and health as well as the severity of symptoms&also type of worms infesting.
Please consult your family physician for physical assessment of your health, stools examination to confirm type of worms, and then prescribe specific drugs in suitable dosage for you&also how many courses need to be repeated followed by a suitable gap between courses.
Hope I have answered your query. Follow up query is welcome.
