Afrin All Night does a great job of clearing my sinuses, even when I'm suffering from the worst head cold or allergy attack. Although other nasal sprays have the nasty side effect of dripping down my nose and throat, leaving a horrendous aftertaste in my mouth, this formula really stays where it's needed. It starts working pretty much immediately, and lasts for a good 8-9 hours (although the box advertises 12 hours of relief). Since it doesn't make me jittery or jumpy, I can use it before bedtime, allowing me to get the rest I really need.
The product's box says it contains chamomile to help soothe inflamed sinuses. I did find that this product doesn't seem to irritate my sinuses like other nasal sprays I've tried.
Since you can't feel better if you can't get any rest, this product's is a must-have for my medicine cabinet.
