What is penicillin V potassium and how does it work?
Penicillin V potassium is a natural penicillin antibiotic in the beta-lactam family. It works by attacking the cell walls of penicillin-susceptible (penicillin G-sensitive) bacteria, stopping them from growing so your body can clear the infection. It is FDA-approved for mild-to-moderate infections, including upper respiratory tract infections such as streptococcal pharyngitis ("strep throat"), scarlet fever, mild erysipelas, mild-to-moderate skin and soft-tissue infections, and Vincent's infection (fusospirochetosis) of the mouth and throat. It is also used to help prevent the recurrence of rheumatic fever and, per American Heart Association guidance, to help prevent bacterial endocarditis in certain heart patients undergoing dental or upper-respiratory procedures.
It is not intended for severe infections such as pneumonia, bacteremia, meningitis, or arthritis in the acute stage, which require different treatment. Your prescriber will decide whether penicillin V potassium is right for your specific infection.
How much does penicillin V potassium cost without insurance?
The brand-name versions of penicillin V potassium have all been discontinued in the US, so today it is available only as a generic. Generics like this are already among the most affordable antibiotics, but that does not mean every pharmacy charges the same. Cash prices can differ significantly between pharmacies in the same town, which is exactly why comparing matters, especially if you do not have insurance or your plan does not cover it well.
Rx.com compares live cash prices across more than 60,000 pharmacies so you can see where it costs the least near you. Enter your ZIP above to see today's price, then show the coupon at the pharmacy counter. There is no membership fee to use it.
Related antibiotics and alternatives
Penicillin V potassium is one of several antibiotics a prescriber may choose depending on the type of infection and any allergies you have. Other commonly prescribed options include amoxicillin, amoxicillin-clavulanate, cephalexin, azithromycin, and clindamycin. For people with a penicillin allergy, a non-penicillin option such as azithromycin or clindamycin is often used instead.
Only your prescriber can decide which antibiotic fits your infection, so never switch on your own. If you are prescribed a different drug, you can compare its price on Rx.com the same way.
Safety and side effects
Penicillin V potassium has no boxed warning, but it should not be used by anyone with a history of penicillin or other beta-lactam allergy. Serious and occasionally fatal allergic (anaphylactic) reactions can occur, and they are more likely in people with a history of penicillin sensitivity or multiple allergies; there is also a possibility of cross-reactivity with cephalosporin antibiotics. Tell your provider about any drug allergies before starting. Antibiotics like this can also cause Clostridioides difficile-associated diarrhea, which ranges from mild diarrhea to serious colitis and can begin even weeks after you finish the medicine.
For best absorption, take penicillin V potassium on an empty stomach, and finish the full course even if you feel better, to help prevent resistance. The most common side effects are usually mild and include nausea, vomiting, diarrhea, and rash or hives. This is general information and not medical advice; talk with your doctor or pharmacist about your specific situation and report any severe rash, swelling, trouble breathing, or persistent diarrhea right away.
