I would say yes because for it to cause stomach discomfort it would have to be ingested and the pill opened. Another thing doxy is given in 14 100mg doses so it can stay present in you system so your next does or your previous dose should handle your worries.
Probably, doxycycline is ingested pretty quickly, compared to Biaxin XL or something like that. However it's hard to say exactly.
thanks. my question was more about whether or not the medicine remained in my system after vomiting an hour after taking it?
eat before you ake your meds and yes cause it caused it
