Before taking penicillin V potassium, tell your doctor and pharmacist if you are allergic to penicillin V potassium, other penicillin antibiotics, cephalosporin antibiotics such as cefaclor, cefadroxil, cefazolin Ancef, Kefzol , cefepime Maxipime , cefixime Suprax , cefotaxime Claforan , cefotetan, cefoxitin Mefoxin , cefpodoxime, cefprozil, ceftaroline Teflaro , ceftazidime Fortaz, Tazicef, in Avycaz , ceftibuten, ceftriaxone, cefuroxime Ceftin, Zinacef , and cephalexin Keflex ; any other medications, or any of the ingredients in penicillin V potassium tablets or oral solution.
Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Also, tell your doctor if you have or have ever had allergies, asthma, hay fever, or kidney disease. If you become pregnant while taking penicillin V potassium, call your doctor.
Unless your doctor tells you otherwise, continue your normal diet. Penicillin V potassium may cause side effects. When a bacterium multiplies, small holes open up in its cell walls as the cells divide. Newly-produced peptidoglycans then fill these holes to reconstruct the walls. Penicillins block the protein struts that link the peptidoglycans together. This prevents the bacterium from closing the holes in its cell walls. As the water concentration of the surrounding fluid is higher than that inside the bacterium, water rushes through the holes into the cell and the bacterium bursts.
People generally attribute the discovery of penicillins to Alexander Fleming. The story goes that he returned to his laboratory one day in September to find a Petri dish containing Staphylococcus bacteria with its lid no longer in place. The dish had become contaminated with a blue-green mold called Penicillium notatum.
Fleming noted that there was a clear ring surrounding the mold where the bacteria had been unable to grow. By discovering this mold and recognizing its use, Fleming set the wheels in motion to create one of the most useful drugs in medical history. In March , Anne Miller became the first civilian to receive successful treatment with penicillin. She narrowly avoided death following severe infection after a miscarriage. Although Fleming technically discovered the first antibiotic, scientists had to do a lot of work before penicillins could become available for general use.
Scientists with a superior laboratory and a deeper understanding of chemistry than Fleming carried out the bulk of the work. Howard Florey, Norman Heatley, and Ernst Chain performed the first in-depth and focused studies on the drug. This has since become a problem.
