Nasal Congestion
"I started this medication 5 days ago due to post nasal drip, phlegm coughs, runny nose... My doctor told me to take 24 hour. As far as side effects: I experienced slight insomnia...a little longer to fall asleep, my head is not quite clear, I feel a little foggy, when I need to concentrate and a little fatigue. No major side effects. The medication has helped but has not completely &quot;cured&quot; me. So overall, it&#039;s worked but it&#039;s not a miracle."
