The dose for children under 12 years old is based on body weight. The recommended daily dose ranges from 25 mg to 100 mg per kg of body weight and is divided into 3 or 4 equal doses.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Medications other than those listed above may interact with Apo Pen Vk. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking.

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take Apo Pen Vk.

Allergy: Some people who are allergic to cephalosporin antibiotics also experience allergic reactions to penicillin. Before you take penicillin, inform your doctor about any previous adverse reactions you have had to medications, especially cephalosporins and other penicillins. Contact your doctor at once if you experience signs of an allergic reaction, such as skin rash, itching, difficulty breathing or swelling of the face and throat.

Antibiotic-associated colitis: Apo Pen Vk, like other antibiotics, may cause a potentially dangerous condition called antibiotic-associated, or pseudomembranous, colitis. Symptoms include severe, watery diarrhea that may be bloody. If you notice these symptoms, stop taking penicillin and contact your doctor as soon as possible.

Bacterial resistance: Misuse of an antibiotic such as penicillin may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better when you first start taking penicillin, you need to take all of the medication exactly as prescribed by your doctor to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take penicillin or other antibiotics to treat a viral infection such as The Common Cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.

Birth control: Whether penicillin decreases the effectiveness of birth control pills is controversial. Some doctors recommend adding another method of birth control for the rest of the menstrual cycle when penicillin is taken.

Kidney function: Penicillin is removed from the body by the kidneys. People with impaired kidney function are at risk of increased side effects and may need lower doses of penicillin. People with Kidney Disease or reduced kidney function should discuss with their doctor how Apo Pen Vk may affect their medical condition, how their medical condition may affect the dosing and effectiveness of Apo Pen Vk, and whether any special monitoring is needed.

Overgrowth of organisms: Prolonged treatment with penicillin may allow normal fungus or types of bacteria not killed by the antibiotic to overgrow, causing unwanted infections such as yeast infections.

Pregnancy: Usual doses of penicillin appear to be safe during pregnancy.
