Cough
"I started taking this due to my severe Sinusitis, I started noticing more frequent nightmares 4 nights in a row and decided to search this medication&#039;s side effects/symptoms as another medication has caused me nightmares. Sure enough there are many reports of nightmares, as well as, the medication having no improvements. I have no relief and will just take OTC cough meds again. DO NOT TAKE THIS MEDICATION!!!"
