Penicillin VK is an antibiotic used to treat various infections by weakening the bacteria by interfering with the growth of the bacteria cell wall.
People who are allergic to any ingredient used to make penicillin should not take penicillin VK. Those who are taking tetracycline antibiotics should not take penicillin until they have completed the other antibiotic.
Several medications interact with penicillin VK, so anyone taking prescription or non-prescription medications on a regular basis should let a doctor know before taking penicillin VK. Some people are at a higher risk for penicillin causing allergic reactions or side effects, such as those who are pregnant, those already suffering from a stomach virus that have diarrhea as a symptom and anyone who has an existing food or medication allergy.
Penicillin VK is taken orally and is best absorbed on an empty stomach. The medication is best taken at the same time each day. If a dosage is missed, it can be taken as soon as remembered, but if it is too close to the next dosage time, it is best to skip the dose and continue taking the medication as directed from there on out.
