I have used Allegra-D for about 7 years and it is a lifesaver. This is the ONLY medicine that has stopped my sinuses from profuse congestion. My itchy, runny nose, scratchy throat, itchy eyes, are all gone. if i miss a day, believe me, i notice it. it does indeed give you dry mouth, like most decongestants, but drinking lots of water is good for you anyway. i've also learned to take it in the morning instead of at night as it would keep me awake.

Allegra is great. Leaves you a little dry nosed, and dehydrated. So drink a lot of water. Published: October 22, 2007 ::

Unable to take over the counter allergy meds, they cause very rapid heart rate and dizziness. Claritin also causes side effetcs. Allegra D is the best allergy medication around. No side effects thus far. If I miss a dose, I can definitely feel it. Published: February 15, 2008 ::

I experienced dizziness for the first week or two. Every evening I experiences stomach distress until I took and over-the counter medicine to calm the effects. Not effective enough to put up with the side effects. Published: September 30, 2007 ::

Don't take medicine close to bed time. It will keep you up all night. Published: June 23, 2008 ::

This medicine makes me groggy and if I take it every 12 hours dries my nose and throat out too much. On the other hand, if I try to go without, I am sneezing and blowing my nose all day. I only take one a day and seem to do OK with that dosage. Published: April 04, 2008 ::

I have been using Allegra D for years, but at the moment I am uneployed and can not afford to buy this medication. It has really taken it's toll on me. Published: March 30, 2009 ::

I have tried almost all allergy meds and find that Allegra-D works best for my seasonal allergy symptoms. I have had no side effects and I highly recommend it. Published: March 15, 2009 ::

Allegra-D does work very well for the treatment of my allergies, however, it is recommended you take this medication on an empty stomach. I have trouble taking anything on an empty stomach. If I eat something little like toast before I take it in the morning the side effects are not as bad. I was having headache, dry mouth, dizziness, and nausea. The product does work well you just have to get past the side effects. I take allergy medication year round, so I knew I would have to try and figure out how to control the side affects.

I was given this medicine for a sinus infection. I was without sleep for 4 days, nauseous at night and just plain miserable. Not worth the side effects, I couldn't work properly and effectively feeling that way. Published: January 13, 2008 ::

Takes a couple doses, but very effective if patient Published: December 19, 2007 ::

I suffered from unexplained vertigo for several years. My ears, nose, and throat specialist finally deduced after numerous tests that I suffered from negative pressure trapped within my inner ear when the barometric pressure changed and I became congested, albeit gradually. This is the best remedy I have discovered after using numerous decongestants and antivert meds. Published: December 13, 2007 ::
