i have been prescribed the antibiotic erythromycin by a dentist and i began the course ysterday, due to a burning sensation much like heartburn, and a pain in the same area, i went to the pharmacy to get something, she gave me gaviscon and domerid relief tables, both of which i took immediatly, after half an hour i am vomitting, dizzy, headache, and stomach pain, i took it upon myself to read the information on both packs i got from the pharmacy today, and read that u cannot take the antibiotic erythromycin with domerid relief tablets, i found further info on the interenet and now i am worried. can u advise me what to do, firstly, amm i in danger, secondly if i want to make a complaint about the pharmacist that gave me the medicine
