Allegra

Allegra immediately stopped a very strong cough I've had for years. No other medicine has worked like this. I had stopped going any where because of this awful cough. However, it makes me lethargic and achy (just as Nsm below described) and it appears to have effected my short term memory, because I can't focus on anything more than a minute since I started taking the Allegra about 2 months ago. It's very noticable and worries me the most. I also get a strange feeling headache on left side of head only for just a minute about once a day. It seems sinus related. I also take one sudafed a day, instead of the AllegraD. I take no other medicine other than Omneprazole.

Painful headache on the side of my head. Achiness all over, at first I thought I was coming down with the flu but stopped taking Allegra and achiness went away and then took Allegra two days later just to see what would happen.
Headache returned within a couple of hours, achiness and then a lethargy set in. Pretty significant reaction for me. I've never had any side effect to any other allergy medication before except for a little drowsiness with Zyrtec and Benadryl.

Headache and congestion better but have upset stomach.

Does everyday use of Allegra cause high blood pressure?
