Gaw MemberMember0(@gaw) Posted : 02/19/2014 1:18 am Hi all,my face has become very red since I took doxycycline capsules 5 days ago. May I ask if I should go to see a doctor or continue taking them? Quote David Lortscher MemberMember2(@david-lortscher) Posted : 02/19/2014 6:16 pm Hi, yeah I think you should probably see a doctor and stop taking them for now. Doxycycline can cause extreme sensitivity to the sun in some people, and that often shows up on the face.
