The DS form is taken every twelve hours (twice a day) regardless of weight. The usual duration of therapy is five to ten days, with seven being average.
This assumes that you know that you are not allergic to sulfa medications like Septra.

Well, it really doesn’t matter because after sitting on the shelf for a year your Bactrim likely won’t contain much active antibiotic. Bactrim is also formulated to take for ten days, as a rule, so you likely won’t have enough tablets left to do any good anyway. It’s dangerous to keep old prescriptions hanging around. You should always finish the full prescription of an antibiotic as well. While you may well have a sinus infection, old antibiotics are not the answer. Even in the most perfect scenario, with the Bactrim being full strength and effective against the bacteria causing your infection, not having the full dosage means you may not kill all of it off. Whatever bacteria are left will be the sort that are resistance to it somewhat, and you will not be cured. But you will be infected with antibiotic resistant critters, and you will have exposed the staph in your nose to an antibiotic as well. Can you say MRSA? That’s how it got it’s start, through misuse of antibiotics. So, don’t take those old Bactrim. Get yourself a sinus medication designed to drain the sinuses, and some pain medication for the achy head, or a sinus medication with the pain med in it. And call your doctor to be seen and get a new prescription if it’s indicated. Then, take all your antibiotic, exactly as you are directed on the label. And when you are feeling better, empty the cabinet of all the old prescriptions like that, lest you be tempted again. They aren’t safe, and some old medications can be downright dangerous.
Okay-
First, any antibiotics which were not used at the time they were originally prescribed need to be discarded. Over time pills expire and are less effective. Additionally the bactrim may not be what your practitioner would want you to take for a sinus infection. Be careful, many upper respiratory tract diseases are actually caused by a virus, which will not respond to bactrim or any other antibiotic. Taking antibiotics when not indicated can actually make you worse or lead to the development of resistant strains of bacteria.
If you’re not feeling well and you think its more than a cold, or if you’re just not sure, call your practitioner and get checked. That’s the safest thing to do . Good luck and feel better.
