What is Pvf?
Penicillins are used to treat infections caused by bacteria. They work by killing the bacteria or preventing their growth.
There are several different kinds of penicillins. Each is used to treat different kinds of infections. One kind of Pvf usually may not be used in place of another. In addition, penicillins are used to treat bacterial infections in many different parts of the body. They are sometimes given with other antibacterial medicines (antibiotics). Some of the penicillins may also be used for other problems as determined by your doctor. However, none of the penicillins will work for colds, flu, or other virus infections.
Penicillins are available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, penicillins are used in certain patients with the following medical conditions:
- Chlamydia infections in pregnant women—Amoxicillin and ampicillin
- Gas gangrene—Pvf G
- Helicobacter pylori-associated gastritis or peptic ulcer disease—Amoxicillin
- Leptospirosis—Ampicillin and Pvf G
- Lyme disease—Amoxicillin and Pvf
- Typhoid fever—Amoxicillin and ampicillin
Pvf indications
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Pvf Potassium and other antibacterial drugs, Pvf Potassium should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Pvf Potassium tablets are indicated in the treatment of mild to moderately severe infections due to Pvf G-sensitive microorganisms. Therapy should be guided by bacteriologic studies (including sensitivity tests) and by clinical response.
NOTE: Severe pneumonia, empyema, bacteremia, pericarditis, meningitis, and arthritis should not be treated with Pvf during the acute stage. Indicated surgical procedures should be performed.
The following infections will usually respond to adequate dosage of Pvf.
Streptococcal Infections (without bacteremia)
Mild-to-moderate infections of the upper respiratory tract, scarlet fever, and mild erysipelas.
NOTE: Streptococci in groups A, C, G, H, L, and M are very sensitive to Pvf. Other groups, including group D (enterococcus), are resistant.
Pneumococcal Infections
Mild to moderately severe infections of the respiratory tract.
Staphylococcal infections – Pvf G-sensitive
Mild infections of the skin and soft tissues.
NOTE: Reports indicate an increasing number of strains of staphylococci resistant to Pvf G, emphasizing the need for culture and sensitivity studies in treating suspected staphylococcal infections.
Fusospirochetosis (Vincent’s gingivitis and pharyngitis)
Mild to moderately severe infections of the oropharynx usually respond to therapy with oral Pvf.
NOTE: Necessary dental care should be accomplished in infections involving the gum tissue.
Medical conditions in which oral Pvf therapy is indicated as prophylaxis: For the prevention of recurrence following rheumatic fever and/or chorea: Prophylaxis with oral Pvf on a continuing basis has proven effective in preventing recurrence of these conditions.
Although no controlled clinical efficacy studies have been conducted, Pvf has been suggested by the American Heart Association and the American Dental Association for use as an oral regimen for prophylaxis against bacterial endocarditis in patients who have congenital heart disease or rheumatic or other acquired valvular heart disease when they undergo dental procedures and surgical procedures of the upper respiratory tract1.
Oral Pvf should not be used in those patients at particularly high risk for endocarditis (e.g., those with prosthetic heart valves or surgically constructed systemic pulmonary shunts). Pvf should not be used as adjunctive prophylaxis for genitourinary instrumentation or surgery, lower-intestinal tract surgery, sigmoidoscopy, and childbirth. Since it may happen that alpha hemolytic streptococci relatively resistant to Pvf may be found when patients are receiving continuous oral Pvf for secondary prevention of rheumatic fever, prophylactic agents other than Pvf may be chosen for these patients and prescribed in addition to their continuous rheumatic fever prophylactic regimen.
NOTE: When selecting antibiotics for the prevention of bacterial endocarditis, the physician or dentist should read the full joint statement of the American Heart Association and the American Dental Association1.
How should I use Pvf?
Use Pvf as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Pvf is usually given as an injection at your doctor's office, hospital, or clinic. If you will be using Pvf at home, a health care provider will teach you how to use it. Be sure you understand how to use Pvf. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.
- Do not use Pvf if it contains particles, is cloudy or discolored, or if the vial is cracked or damaged.
- Pvf works best if it is given at the same time each day.
- Pvf is injected into a muscle. Pvf should not be injected into or near an artery or vein.
- To clear up your infection completely, use Pvf for the full course of treatment. Keep using it even if you feel better in a few days.
- Keep this product, as well as syringes and needles, out of the reach of children and pets. Do not reuse needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.
- If you miss a dose of Pvf and you are using it regularly, use it as soon as possible. If it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Pvf.
