So I just looked up Thomas Labs penicillin, and it says that it's penicillin V. So then I looked up penicillin V and this is what I found:
"Penicillin V is phenoxymethylpenicillin. Pen VK is just its potassium salt. Penicllin V is less active than penicillin G (benzylpenicillin) against gram-negative bacteria, but penicillin V is more acid-stable than penicillin G, so it can be given orally."

and
"Penicillin G benzathine, potassium, procaine and sodium are currently available in the United States in parenteral formulations for intravenous or intramuscular use. Penicillin V potassium (also called phenoxymethyl penicillin) is a more acid stable and can be administered orally."

So if you have penicillin V, it can be given orally.
