Penicillin VK - Overview
Penicillin (oral), marketed as penicillin-VK, is an antibiotic medication used to treat infections that are thought to be susceptible to the medication. Push Health can connect people who think they need a penicillin prescription with licensed medical providers who can prescribe the medication when appropriate to do so.
How Does Penicillin Work?
Penicillin is a type of antibiotic medication that is used to treat certain bacterial infections, most often strep throat caused by susceptible group A streptococcus. Penicillin works by interfering with building of cell walls in susceptible bacteria.
Penicillin is structurally similar to a number of other antibacterial medications such as amoxicillin, ampicillin and dicloxacillin. For many types of infections, the use of penicillin has been replaced by cephalosporins such as cefaclor (Ceclor), cefdinir (Omnicef), cefixime (Suprax), cefpodoxime (Vantin), cefuroxime (Ceftin), and cephalexin (Keflex) due to resistance. Many staph infections are resistant to penicillin VK.
Penicillin - Dosage and Cost
A common adult strep-throat course prescribed is penicillin 500 mg every 6 to 8 hours for 10 days. The medication should be taken on an empty stomach when possible (e.g. 1 hour before or 2 hours after a meal) and the entire course should be finished, even if symptoms resolve.
Oral penicillin is considered very affordable at under 30 cents per tablet at many pharmacies. Insurance plans and prescription discount cards may also help with any medication costs.
