How long does it take for penicillin to start working on a throat infection?

Penicillin typically takes around 3 to 4 days to start working on a throat infection. It is important to continue taking the full 10-day course of antibiotics, even if the symptoms improve before then. If you experience discomfort due to the infection, you can also take ibuprofen to help with pain relief. Feel free to reach out if you have any further questions.
