doxycycline can be used for more than just antibiotics. it's also used for SIADH, high ammonia levels, etc. what is your 21 year old on this for???
my listed side effects in my PDR are: anoxrexia, trouble swallowing, stomach/GI distress, rashes, sensitivity to light, hives,
is your 21 year old on anyother meds/herbs? those can also interfere. doxycycline can interfere with antacids, antiseizure meds, iron, contraceptives, penicillins, alcohol.
you may want to call the doctor and explain this s/e. it's always a good idea to talk to the doc when an unexpected side effect occurs. maybe this is just unrelated effect that just seems to be occuring. in any case, it's a great idea to call your doc/NP and talk about this. depression needs to be treated, i'm sure you know that. i don't know what your child is on the doxy for, so it's a bit difficult to give more info. i am a nurse though but i will try to help any way i can.
