Hi my dear,
Pin X is the brand name for the generic Pyrantel pamoate
. It is an anti-worm drug.
Usually, it is given as 11 mg per kg weight. In other words, if your weight is 75 kg, the dose of pin x should be around 750 mg and repeated after 2 weeks.
So, if you have taken the first dose 4 days ago, you should take the next dose after 2 weeks.
However, I'd suggest to do the testing before taking the other dose to determine the right diagnosis and what other medications you should take.
Meanwhile, I'd suggest to follow good hygienic measures, especially when going to the bathroom and when preparing the food.
Please avoid sugary foods; and drink more water! I usually advise my patients to eat raw garlic on daily basis for enhancing the chances for de-worming.
All the best!
