Allergic Rhinitis
"When fall sets in so do allergies where I live. After a trip to the doctor I was prescribed Allegra D- 12 Hour, and found that I had the sinus pressure relieved within 2 1/2 - 3 hours. However when drugs.com list states &#039;dizziness&#039; as a side effect, they&#039;re not kidding. I had to get someone to take me home because I (personally) was too dizzy to even walk straight. So if this is prescribed to you I would suggest taking it on a day &#039;off&#039; such as a weekend, or at night to discover how it affects you personally before you take it on a work day and find out the bad way."
