More information

  • Usage

    Penicillin is an antibacterial medication that is used to treat or prevent infections that are strongly suspected or proven to be caused by bacteria, especially microorganisms susceptible to penicillin. Penicillin V’s mechanism of action is interfering with the cell wall synthesis of microorganisms sensitive to penicillin during replication. Historically, penicillin has been indicated to treat susceptible Streptococcal infections (e.g. strep throat), Pneumococcal infections and Staphylococcal infections. Penicillin is structurally similar to a number of other antibacterial medications such as amoxicillin. For many types of infections, the use of penicillin has been replaced by cephalosporins such as cephalexin and cefdinir due to antibiotic resistance.

  • Penicillin – Side Effects

    Penicillin, like other antibiotics, cause result in side effects when used. Common side effects include nausea, vomiting, stomach pain and diarrhea. People who have a known hypersensitivity or allergy to penicillin should not use the medication. Penicillin and alcohol should not be used together. Concerns about possible side effects related to penicillin use should be discussed with one’s medical provider and pharmacist.

  • Cost Information

    Penicillin VK is considered very affordable at under 30 cents per tablet at many pharmacies. Insurance plans may also cover any costs associated with a penicillin tablet prescription and penicillin V coupons may also be available online at times. Farmington Drugs & Medical Supplies takes pride in offering the most cost efficient services and prescriptions to our patients.

  • Dosage

    Penicillin V is frequently administered as penicillin 250 mg or penicillin 500 mg every 6 to 8 hours. Penicillin V is similar to penicillin G as it is the phenoxymethyl analog of it. Penicillin – VK, also known as penicillin V potassium tablets, are made for oral administration as penicillin 250 mg or penicillin 500 mg tablets. The potassium salt added to penicillin V makes it more resistant to deactivation by acid in the stomach. In the serum, the majority of penicillin V is bound to proteins and penicillin in the body is excreted rapidly in healthy people. Penicillin-VK tablets are biconvex white tablets and should be stored at 20° C to 25° C in a tight container.
