Patient :Hi Doc, my names James and I've been taking the Omnaris Nasal Spray & Cetirizine Hydrochloride 20 mg both for my allergies per day, my doctor prescribed me to take it for my allergies. I was just wondering if Omnaris Nasal Spray and Cetirizine Hydrochloride 20 mg either one can cause drowsiness throughout the day if taken. Also (note) I take the Cetirizine Hydrochloride 20 mg (Bedtime) only, but I was also wondering if it could be a 24 hour affect too. I'm willing to hear more information and feed back on this, thank you - James
