That's the point....it requires a prescription!
I occasionally get bad sinus attacks.....I've been prescribed a specific antibiotic when I do....
To get the prescription, I have to make an appointment to see the doctor....usually a couple of days later, during which time I will suffer with headaches and toothaches, and possibly the sinus attack will progress into a bad infection....then I have to take time off from work, and sit around the waiting room for a couple of hours (doctors are usually not on schedule!)....getting exposed to who knows what from others in the waiting room....then I have to convince the doctor that I have a sinus attack, and need a prescription, and convince that same doctor that the common amoxicillin will not take care of my ailment....then if I've been successful, I get the prescription, pay my $20 (or higher copayment)...that is , if the doctor has not decided to require additional tests to cover his butt...then I head to the pharmacy to fill it.
The joys of the medical "industry"!!!
I prefer to have a supply of that antibiotic handy sitting around at home...and take it when I feel the sinus attack coming on, and avoid all of the above!!!
RANT ended!!!!
