Pyrantel Pamoate: How often can I repeat? Diatomaceous Question.

I have a bottle of Pyrantel Pamoate 50mg. I took 2 1/2 teaspoons according to my weight per bottle instructions and was wondering if I can take another dose? According to the bottle it says to take it only once but unfortunately I have scatter and migration from a deworming herbal tincture and because of this I'm waiting for the worm or worms to get back into my GI tract so I can hit them with the Pyrantel as soon as they do.

I've ordered Albendazole for my Ascaris infection but it will not arrive for another 2-3 weeks and I feel like I need to do at least something if or when it migrates back to the correct location.

Diatomaceous earth- Can I keep drinking this until the Albendazole arrives or should I eliminate this as well?
