Hi, my daughter had pinworms, took 1 dose of Reece medication otc, threw up about 10 hours later and felt icky but did ok, followed up per bottle & pharmacist recommendation 2 weeks later, worms were long gone but this was to kill any eggs that supposedly may have been left behind. She got sick this time fast! less than 2 hours later and has been throwing up and had diarrhea ever since, feeling like the flu. Poor kid! It s been almost 12 hours. What can I do, if anything, besides the usual Mom stuff.
