Hello, If she took the pill (and it was the first time), and she had vomiting this morning and drowsiness, then, should stop the pill, and report this as side effect to the doctor who prescribed Dronis 30. Otherwise, if this was not the first time she took the pill, and started vomiting this morning, it could be something else, for example, acute gastroenteritis or food poisoning. In this case, should seek immediate medical help for proper diagnosis and treatment. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Albana Sejdini, General & Family Physician
