Description: Penicillin VK is an antibiotic classified as a narrow-spectrum penicillin, meaning it kills a relatively small range of bacteria.
Dental Uses: For many dental infections, including dental abscesses, infections around wisdom teeth and infections after surgery, no other antibiotic works better, is safer and costs less than penicillin VK. Unlike its predecessor, penicillin G, penicillin VK can withstand stomach acid when swallowed.
Dosages for dental purposes: The typical adult dose is 250 milligrams to 500 milligrams every six hours for seven to 10 days. Dosages for children are based on body weight.
Concerns and possible side effects: Side effects occur occasionally and include nausea, vomiting and diarrhea. Occasionally, penicillin VK temporarily turns the tongue a black color, a condition called black hairy tongue. Penicillin VK and other penicillins should not be taken by people with documented allergies to these drugs. Allergic reactions can range from a mild rash to life-threatening closure of the airway and a fall in blood pressure.
