PENICILLIN V POTASSIUM - ORAL LIQUID
(pen-ih-SILL-in VEE poh-TASS-ee-um)
COMMON BRAND NAME(S): Ledercillin VK, Pen-Vee K, Veetids
USES:
Penicillin is an antibiotic used to treat and prevent a wide variety of bacterial infections. It works by stopping the growth of bacteria.
This antibiotic treats only bacterial infections. It will not work for viral infections (e.g., common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.
HOW TO USE:
Shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. This medication may be taken with or without food. However, penicillin is best absorbed when taken on an empty stomach (1 hour before or 2 hours after meals).
The dosage is based on your medical condition and response to therapy. In children, the dosage is also based on weight.
Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals.
Continue to take this medication until the full-prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection.
Inform your doctor if your condition persists or worsens.
SIDE EFFECTS:
Upset stomach, nausea, vomiting, diarrhea, and mouth sores may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
Although uncommon, you may develop a black, "hairy" tongue while taking this medication. This effect is harmless and usually goes away after treatment. Maintain good oral hygiene, and brush your tongue with a soft toothbrush twice a day. Consult your doctor or pharmacist for more information.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: unusual tiredness, joint/muscle pain.
Tell your doctor immediately if any of these rare but very serious side effects occur: easy bruising/bleeding.
This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.
Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection (oral or vaginal fungal infection). Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge or other new symptoms.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), new fever, severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS:
Before taking penicillin, tell your doctor or pharmacist if you are allergic to it; or to other antibiotics including penicillin-type medications (e.g., amoxicillin, ampicillin) or cephalosporins (e.g., cephalexin, cefuroxime); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney problems.
This medication may contain aspartame. If you have phenylketonuria (PKU) or any other condition that requires you to restrict your intake of aspartame (or phenylalanine), consult your doctor or pharmacist regarding the safe use of this medicine.
Kidney function declines as you grow older. This medication is removed by the kidneys. Therefore, elderly people may be more sensitive to this drug.
Kidney function is not fully developed in newborns and young infants. This medication is removed by the kidneys. Therefore, newborns and young infants may be more sensitive to this drug.
This medication should be used only when clearly needed during pregnancy. Discuss the risks and benefits with your doctor.
This drug passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS:
Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first.
Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: live bacterial vaccines, methotrexate, tetracyclines, khat, guar gum.
Before taking penicillin, tell your doctor or pharmacist if you are also taking probenecid. Probenecid slows down the removal of penicillin from your body, resulting in higher levels of this antibiotic in your bloodstream. For certain types of difficult-to-treat infections, your doctor may prescribe these 2 medications together in order to achieve this effect. Consult your doctor or pharmacist for more details.
Although most antibiotics probably do not affect hormonal birth control such as pills, patch, or ring, some antibiotics may decrease their effectiveness. This could cause pregnancy. Examples include rifamycins such as rifampin or rifabutin. Be sure to ask your doctor or pharmacist if you should use additional reliable birth control methods while using this antibiotic.
Penicillin may cause false positive results with certain diabetic urine testing products (cupric sulfate-type). This drug may also affect the results of certain lab tests. Make sure laboratory personnel and your doctors know you use this drug.
This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
OVERDOSE:
If overdose is suspected, contact your local poison control center or emergency room immediately. US residents can call the US national poison hotline at 1-800-222-1222. Canadian residents should call their local poison control center directly. Symptoms of overdose may include: severe vomiting, persistent diarrhea.
NOTES:
Do not share this medication with others.
This medication has been prescribed for your current condition only. Do not use it later for another infection unless told to do so by your doctor. A different medication may be necessary in those cases.
With prolonged treatment, laboratory and/or medical tests (e.g., kidney function, complete blood counts) should be performed periodically to monitor your progress or check for side effects. Consult your doctor for more details.
MISSED DOSE:
If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.

Used to treat patients allergic to penicillin. Inhibits bacterial growth, possibly by blocking dissociation of peptidyl tRNA from ribosomes causing RNA-dependent protein synthesis to arrest.
Anti-inflammatory agents
Class Summary
The manifestations of acute rheumatic fever (including carditis) typically respond rapidly to therapy with anti-inflammatory agents. Aspirin, in anti-inflammatory doses, is the drug of choice. Prednisone is added when evidence of worsening carditis and heart failure is noted.
Also called acetylsalicylic acid. Inhibits prostaglandin synthesis, which prevents formation of platelet-aggregating thromboxane A2. Start immediately after the diagnosis of rheumatic fever has been made. Initiation of therapy may mask manifestations of the disease.
May decrease inflammation by reversing increased capillary permeability and suppressing PMN activity. If moderate to severe carditis is indicated by cardiomegaly, congestive heart failure, or third-degree heart block, 2 mg/kg/d PO should be used in addition to, or in lieu of, salicylate therapy. Prednisone should be continued for 2-4 wk, depending on the severity of the carditis, and tapered during the last week of therapy. Adverse effects can be minimized by discontinuing prednisone therapy after 2 wk and adding or maintaining salicylates for an additional 2-4 wk.
Angiotensin-converting enzyme (ACE) inhibitors
Class Summary
These agents are competitive inhibitors of ACE. They reduce angiotensin II levels and thus decrease aldosterone secretion.
Indicated for chronic aortic and/or mitral regurgitation. Prevents conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, resulting in increased plasma renin levels and a reduction in aldosterone secretion. Helps control blood pressure and proteinuria. Decreases pulmonary-to-systemic flow ratio in the catheterization laboratory and increases systemic blood flow in patients with relatively low pulmonary vascular resistance. Has favorable clinical effect when administered over a long period. Helps prevent potassium loss in distal tubules. Body conserves potassium; thus, less oral potassium supplementation needed. Goal is to decrease afterload to left ventricle (by reducing systemic blood pressure and by peripheral vasodilatation).
Prevents conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, resulting in lower aldosterone secretion.
Rapidly absorbed, but bioavailability is significantly reduced with food intake. It achieves a peak concentration in 1 h and has a short half-life. The drug is cleared by the kidneys.
Impaired renal function requires reduction of dosage. Absorbed well PO. Give at least 1 h before meals. If added to water, use within 15 min.
Can be started at low dose and titrated upward as needed and as patient tolerates.
Complications
Potential complications include heart failure from valve insufficiency (acute rheumatic carditis) or stenosis (chronic rheumatic carditis). Associated cardiac complications include atrial arrhythmias, pulmonary edema, recurrent pulmonary emboli, infective endocarditis, intracardiac thrombus formation, and systemic emboli
Prognosis
Manifestations of acute rheumatic fever resolve over a period of 12 weeks in 80% of patients and may extend as long as 15 weeks in the remaining patients.
Rheumatic fever was the leading cause of death in people aged 5-20 years in the United States 100 years ago. At that time, the mortality rate was 8-30% from carditis and valvulitis but decreased to a 1-year mortality rate of 4% by the 1930s.
Following the development of antibiotics, the mortality rate decreased to almost 0% by the 1960s in the United States; however, it has remained 1-10% in developing countries. The development of penicillin has also affected the likelihood of developing chronic valvular disease after an episode of acute rheumatic fever. Before penicillin, 60-70% of patients developed valve disease as compared to 9-39% of patients since penicillin was developed.
In patients who develop murmurs from valve insufficiency from acute rheumatic fever, numerous factors, including the severity of the initial carditis, the presence or absence of recurrences, and the amount of time since the episode of rheumatic fever, affect the likelihood that valve abnormalities and the murmur will disappear. The type of treatment and the promptness with which treatment is initiated does not affect the likelihood of disappearance of the murmur. In general, the incidence of residual rheumatic heart disease at 10 years is 34% in patients without recurrences but 60% in patients with recurrent rheumatic fever. Disappearance of the murmur, when it occurs, happens within 5 years in 50% of patients. Thus, significant numbers of patients experience resolution of valve abnormalities even 5-10 years after their episode of rheumatic fever. The importance of preventing recurrences of rheumatic fever is evident.
Patient Education
Emphasize the importance of prophylaxis against recurrent streptococcal pharyngitis and rheumatic fever with each patient.
