Brief Answer:
Ampicillin 500mg every 6 hours

Detailed Answer:
Hello, I'm Dr. Branch, thanks for using Ask a Doctor. You can use Ampicillin for strep throat, the dose would be 500mg every 6 hours, usually for 10 days. It sounds like you will not have enough for 10 days, and will finish the 30 pills after about 7 days. You might clear the infection in that time, but there is a chance that it will not be completely cleared.

I hope that helps, please let me know if you have any questions about any of that, and I would be glad to discuss it with you further.
