I have been taking Doxycycl hyc 100mg for 11 day's. I started getting itchy scalp and tightness on my scalp and burning. i take one tablet a day. Also my left palm is drying and peeling. Could I be allergic to this medication. I cannot see my doctor until monday. I also use Metrogel on my face and it seems to help the redness. It does not seem to dry my skin. Should I stop using the Doxycycl ....Jim..
