Generic Name: Penicillin V Potassium Tablets (pen-i-SILL-in V poe-TASS-ee-uhm)
Brand Name: Examples include Penicillin-VK and Veetids

Penicillin-VK is used for:

Treating some types of infections caused by certain bacteria.

Penicillin-VK is a penicillin antibiotic. It works by interfering with the formation of the bacteria's cell wall while it is growing. This weakens the cell wall and kills the bacteria.

Do NOT use Penicillin-VK if:

  • you are allergic to any ingredient in Penicillin-VK or to other penicillins
  • you are taking tetracyclines

Contact your doctor or health care provider right away if any of these apply to you.

Before using Penicillin-VK :

Some medical conditions may interact with Penicillin-VK . Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have diarrhea or a stomach infection, especially in children 9 years of age or younger

Some MEDICINES MAY INTERACT with Penicillin-VK . Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Chloramphenicol, guar gum, or tetracyclines because the effectiveness of Penicillin-VK may be decreased
  • Anticoagulants (eg, warfarin) or methotrexate because the actions and side effects of these medicines may be increased
  • Anticoagulants (eg, warfarin), chloramphenicol, or oral contraceptives (birth control pills) because the effectiveness of these medicines may be decreased

This may not be a complete list of all interactions that may occur. Ask your health care provider if Penicillin-VK may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use Penicillin-VK :

  • Penicillin-VK is best absorbed when taken on an empty stomach (1 hour before or 2 hours after meals), but may be taken with food.
  • Penicillin-VK should be taken at least 2 hours after KHAT.
  • Penicillin-VK works best if it is taken at the same time each day.
  • To clear up your infection completely, take Penicillin-VK for the full course of treatment. Keep taking it even if you feel better in a few days.
  • Do not miss any doses. If you miss a dose of Penicillin-VK , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Important safety information:

  • Do not take Penicillin-VK if you have had a severe allergic reaction to a penicillin antibiotic (eg, amoxicillin, ampicillin) or a cephalosporin antibiotic (eg, cefaclor, cephalexin, cefuroxime, cefadroxil). A severe allergic reaction includes a severe rash, hives, breathing difficulties, or dizziness. Ask your health care provider if you are unsure if you are allergic to Penicillin-VK .
  • Long-term or repeated use of Penicillin-VK may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.

  • Hormonal birth control (eg, birth control pills) may not work as well while you are using Penicillin-VK . To prevent pregnancy, use an extra form of birth control (eg, condoms).
  • Lab tests may be performed while you use Penicillin-VK . These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Penicillin-VK while you are pregnant.
