Hi, I am 24 years old female. I am suffering from pinworm infection for the last two days. I could not sleep at night as my anal area is itching constantly at nights also I could see white thread like worms in my stool. I have bought zeebee 400 mg from the local pharmacy. They said that only one tablet is enough to get rid of this infection. Is that enough? Or should I get even more to get rid of this pinworms? Please help. Thank you.
