A 'course' of antibiotics is usually several days. You should keep taking the pills until they're gone.
There's a good reason for this, if you want to read a little more. 8^) If you grow a culture of bacteria in a petri dish, and you give them penicillin, not enough to kill all of them but, say, 90%, then when they grow back, they will not respond to the same dose of penicillin, because the ones you didn't kill were the ones who had some immunity to the drug. So you give them ten times as much to kill 90% again, and let them grow back. Within a few generations you have bacteria that penicillin is useless against!
The fact is, since antibiotics were first used, bacteria have all evolved to be resistant to them. We have come up with new antibiotics all the time and they are only good for a few years! Within your lifetime (if you're young) antibiotics may lose their usefulness altogether! Then we'll be screwed. A LOT more people will die of bacterial infections.
BTW my dad told me that during WWII penicillin was so rare and expensive that patients who were given it had to stay in the hospital so their urine could be collected and the unused drug extracted from it to be used again! Aren't you glad you live today? 8^)

Generally a week

Usually 7 to 10 days or until all the pills are gone. You can always ask the pharmacist or doctor.

I'm no doctor, but every time I'm prescribed antibiotics, they always prescribe enough so I can take 10 days of medicine.

Take it until the lesions on your dong subside and the burning upon urination stops.

Always finish your bottles of antibiotics. That's how they're dosed. Take them until they're gone.

probably as many days as your doctor wants you to take it, ask him how many

Until you have taken all of the pills.
