sections and determine the following things?
DIRECTIONS FOR USE

should be administered within one hour after preparation, since the potency
may decrease significantly after this period.
Parenteral drug products should be inspected visually for particulate mat-
ter and discoloration prior to administration, whenever solution and container
permit.
For Intramuscular Use: Dissolve contents of a vial with the amount of Sterile
Water for Injection, USP or Bacteriostatic Water for Injection, USP, listed in the

3. What is the dose for a child
weighing 33 pounds? Per Day? Per
dose?
While Ampicillin for Injection, USP 1 g and 2 g, are primarily for intravenous
use, they may be administered intramuscularly when the 250 mg or 500 mg
vials are unavailable. In such instances, dissolve in 3.5 or 6.8 mL Šterile Water
for Injection, USP or Bacteriostatic Water for Injection, USP, respectively. The
resulting solution will provide a concentration of 250 mg per ml.
Ampicillin for Injection, USP 125 mg, is intended primarily for pediatric use.
It also serves as a convenient dosage form when small parenteral doses of the
antibiotic are required.
Note: Bacteriostatic Water for Injection, USP is not to be used as a diluent
when the product will be used in newborns.
For Direct Intravenous Use: Add 5 mL Sterile Water for Injection, USP, or
Bacteriostatic Water for Injection, USP to the 125 mg. 250 mg, and 500 mg vials
and administer slowly over a 3- to 5- minute period. Ampicillin for Injection,
USP1gor 29, may also be given by direct intravenous administration. Dissolve
in 7.4 or 14.8 ml Sterile Water for Injection, USP, or Bacteriostatic Water for
Injection, USP, respectively, and administer slowly over at least 10 to 15 min-
utes. CAUTION: More rapid administration mav result in convulsive seizures.

DOSAGE AND ADMINISTRATION
Infections of the respiratory tract and soft tissues.
Patients weighing 40 kg (88 Ibs) or more: 250 to 500 mg every 6 hours.
Patients weighing less than 40 kg (88 Ibs): 25 to 50 mg/kg/day in equally
divided doses at 6-to 8-hour intervals.
Infections of the gastrointestinal and genitourinary tracts (including those
caused by Neisseria gonorrhoeae in females).
Patients weighing 40 kg (88 Ibs) or more: 500 mg every 6 hours.
Patients weighing less than 40 kg (88 Ibs): 50 mg/kg/day in equally divided
doses at 6-to 8-hour intervals.
In the treatment of chronic urinary tract and intestinal infections, frequent
bacteriological and clinical appraisal is necessary. Smaller doses than those
recommended above should not be used. Higher doses should be used for
stubborn or severe infections. In stubborn infections, therapy may be required
for several weeks. It may be necessary to continue clinical and/or bacteriological
follow-up for several months after cessation of therapy.
Urethritis in males due to N. gonorrhoeae.
Adults: Two doses of 500 mg each at an interval of 8 to 12 hours.
Treatment may be repeated if necessary or extended if required.
In the treatment of complications of gonorrheal urethritis, such as prostatitis
and epididymitis, prolonged and intensive therapy is recommended. Cases of
gonorrhea with a suspected primary lesion of syphilis should have darkfield
examinations before receiving treatment. In all other cases where concomitant
syphilis is suspected, monthly serological tests should be made for a minimum
of four months.
The doses for the preceding infections may be given by either the intra-
muscular or intravenous route. A change to oral ampicillin may be made when
appropriate.
Bacterial Meningitis.
Adults and children: 150 to 200 mg/kp/day in equally divided doses every 3 to 4
hours. (Treatment may be initiated with intravenous drip therapy and continued with
intramuscular injections.) The doses for other infections may be given by either the
intravenous or intramuscular route.
Neonates (less than or equal to 28 days of postnatal age): Dosage should be
based on Gestational age and Postnatal age according to Table 3.
Table 3: Dosage in Neonates (less than or equal to 28 days of postnatal age)
for Bacterial Meningitis and Septicemia
