Detailed Product Description
INDICATIONS
V is indicated in the treatment of mild to
moderately severe infections due to microorganisms whose
susceptibility to penicillin G is within the of levels common to
this particular dosage form. should be guided by bacteriologic
studies (including susceptibility tests) and by clinical
response.
NOTE: Severe , , , , , and should not be treated
with penicillin V during the .
Indicated surgical procedures should be
performed.
The following infections will usually respond to
adequate dosage of penicillin V:
Streptococcal Infections (without bacteremia): Mild
to moderate infections of the upper tract, , and mild
erysipelas.
NOTE: Streptococci groups A, C, G, H, L, and M are
very susceptible to penicillin. Other groups, including group D (),
are resistant.
Pneumococcal Infections: Mild to moderately severe
infections of the respiratory tract.
Staphylococcal Infections Susceptible to Penicillin
G: Mild infections of the and soft tissues.
NOTE: Reports an increasing number of strains of
staphylococci resistant to penicillin G, which emphasizes the need
for and susceptibility studies in treating suspected staphylococcal
infections.
Fusospirochetosis (Vincent's and ): Mild to
moderately severe infections of the usually respond to therapy with
oral penicillin.
NOTE: Necessary dental care should be accomplished
in infections involving the gum .
Medical Conditions in Which Oral Penicillin Therapy
Is Indicated as : To prevent following and/or . Prophylaxis with
oral penicillin on a continuing basis has proved effective in
preventing recurrence of these conditions.
Although no controlled clinical efficacy studies
have been conducted, penicillin V has been suggested by the
American Association and the for use as an oral for prophylaxis
against endocarditis in patients with or rheumatic or other
valvular when they undergo dental procedures and surgical
procedures of the respiratory tract.1
Since a-hemolytic streptococci relatively resistant
to penicillin may be found when patients are receiving continuous
oral penicillin for secondary prevention of rheumatic , agents
other than penicillin may be chosen for these patients and
prescribed in addition to their continuous prophylactic regimen for
rheumatic fever.
Oral penicillin should not be used as adjunctive
prophylaxis for instrumentation or , lower intestinal tract
surgery, , and childbirth.
NOTE: When selecting antibiotics for the prevention
of bacterial endocarditis, the physician or dentist should read the
full statement of the American Heart Association and the American
Dental Association.1
DOSAGE AND ADMINISTRATION
The dosage of penicillin V potassium should be
determined according to the susceptibility of the causative
microorganism and the severity of and should be adjusted to the
clinical response of the patient.
The usual dosage recommendations for adults and
children 12 years and over are as follows:
Streptococcal Infections: Mild to moderately severe
infections of the upper respiratory tract, including scarlet fever
and mild erysipelas: 200,000 to 500,000 units every 6 to 8 hours
for 10 days.
Pneumococcal Infections: Mild to moderately severe
infections of the respiratory tract, including : 400,000 to 500,000
units every 6 hours until the patient has been afebrile for at
least 2 days.
Staphylococcal Infections: Mild infections of skin
and soft tissue (culture and susceptibility tests should be
performed): 400,000 to 500,000 units every 6 to 8 hours.
Fusospirochetosis (Vincent's Infection) of the
Oropharynx: Mild to moderately severe infections: 400,000 to
500,000 units every 6 to 8 hours.
Prophylaxis in the Following Conditions: To prevent
recurrence following rheumatic fever and/or chorea: 200,000 to
250,000 units twice daily on a continuing basis.
For prophylaxis against bacterial
endocarditis1in patients with heart disease or rheumatic
or other acquired valvular heart disease when undergoing dental
procedures or surgical procedures of the upper respiratory tract, 1
of 2 regimens may be selected:
(1) For the oral regimen, the usual adult dosage is
2 g of penicillin V (1 g for children less than 30 kg) 1 hour
before the procedure and then 1 g (500 mg for children less than 30
kg) 6 hours later.
(2) For patients unable to take oral antibiotics,
2,000,000 units of aqueous penicillin G (50,000 units/kg for
children) IV or IM may be substituted 30 to 60 minutes before the
procedure and 1,000,000 units (25,000 units/kg for children) 6
hours later.
For patients with valves and for those at highest
risk for endocarditis, ampicillin, 1 to 2 g (50 mg/kg for
children), plus gentamicin, 1.5 mg/kg (2 mg/kg for children), IM or
IV, may be given one- half hour prior to the procedure, followed by
1 g of oral penicillin V 6 hours later. Alternatively, the regimen
should be repeated once every 8 hours later.
Children's dosages should not exceed the maximum
adult doses.
NOTE: Therapy for children under 12 years of age is
calculated on the basis of body weight. For infants and small
children, the suggested daily dose is 25,000 to 90,000 units (15 to
50 mg)/kg in 3 to 6 divided doses.
After being mixed, the solution should be stored in
a refrigerator. It may be kept for 14 days without significant loss
of potency. Shake well before using. Keep tightly closed.
Tablets should be stored at controlled room
temperature, 59
