Why was i given only 8 doxycycline 100mg antibiotics?
This drug was commonly given in the past as a specific for sinusitis, though you don’t say why you were prescribed it. Classically 8 were given, with the instruction take 2 on the first day then one daily, hence the 8 pack for a week’s treatment. However most modern doctors are convinced by the research that suggests than antibiotics have no measurable effect on the resolution of sinusitis.
