How many days can we take doxicycline 100mg for upper respiratory infection? and would it be once or 2x a day? thanks.

2 doctors weighed in across 2 answers

Depends: The treatment period and dosing for Doxycycline depends on the severity of the infection. For upper respiratory infections in adults the dosing is usually twice daily for seven days.
