hi, i thought i'd let you know what my doc said. i too have a cold right now. he said that i could not take antihistimine. i have low thyroid, anxiety and high cholestrol. he gave me an antibotic, & told me to tkae robitussin cough syrup. also had to stop taking crestor until antibotic is finished. antihistimine actually can make the anxiety worse. but i was not told of anything else to take. hope this helps you
