It is amazing how many people have experienced tightness in the chest, anxiety, and mood swings with this drug. None of this was mentioned by my doctor when he prescribed doxycyline for my adult acne. And I asked him about all of the side effects, as I was very wary about taking the drug to begin with. Until reading this forum, I thought I was going a little crazy. A generally happy, worry-free person, I experienced anxiety, sleeplessness, tightness in the chest, and trouble breathing. I recently quit taking this medication because I believe it was causing my skin to itch like mad. I already feel better mentally and physically. I will look for another solution for my acne and never again take doxycyline. It is very bad.
