Hi SCM and welcome to the A/P!
Some abx do cause an increase in anxiety in some people. I haven't heard of this symptom specifically, but it could be caused by stress on the body/mind from the underlying issue (whatever illness is necessitating the need for antibiotics) and the medication itself.
If you need to be on the abx long-term...I would ask your prescribing doctor for an alternative that perhaps wouldn't cause this s/e...
...if you are on a short course, try some progressive muscle relaxation and other stress relieving coping skills (see our Resources @ the top of the main forum page here!) for relief.
I hope you get the answers you need soon!
