Scalp itch symptoms and conditions

I am taking Cephalexin 500mg/4x per day. Today is my 2nd day (5 more days to go) and I have tiny red dots all over my legs...it itches......and my arms and back and scalp itch too!

Also, last night, after taking my 3rd dose of the day, my stomach started hurting, I started feeling quesy and my hands started shaking. Have you ever taken a vitamin on an empty stomach (especially a prenatal vitamin) and felt nauseated and maybe even threw up because of it? Well, that's exactly what it felt like. I did end up vomiting and my (pls excuse the grossness) vomit was green. I still had no idea what was causing all this. It wasn't until I came on here today and read all the posts that I realized that all my symptoms were due to the Cephalexin, which are green capsules!!!

Itching scalp and ears appear to be related to taking Allegra. It began last summer (2002) after starting Allegra for hayfever and allergies, but I didn't make the connection. Didn't take Allegra from approximately November, 2002 until April, 2003, and in hindsight, itch almost totally gone. Started on Allegra again in April 2003 when seasonal allergic symptoms began again. Scalp itch flared up immediately, and I made the connection to Allegra. Has anyone else experienced or reported this side effect?
