nasal congestion
"This nasal spray works in seconds and last for hours. I had a cold, stuffy runny nose and a constant draining at the back of my throat which cause me to cough incessantly, after taking otrivin all of my symptoms stopped. It can cause a slight headache if you take too much and you can get addicted because it works so well, then after a while you get rebound congestion so be aware of that, and only use it for a few days"
