Side Effects & Adverse Reactions

Abrupt withdrawal of phenytoin in epileptic patients may precipitate status epilepticus. When in the judgment of the clinician the need for dosage reduction, discontinuation, or substitution of alternative anticonvulsant medication arises, this should be done gradually. In the event of an allergic or hypersensitivity reaction, more rapid substitution of alternative therapy may be necessary. In this case, alternative therapy should be an anticonvulsant not belonging to the hydantoin chemical class.

There have been a number of reports suggesting a relationship between phenytoin and the development of lymphadenopathy (local or generalized) including benign lymph node hyperplasia, pseudolymphoma, lymphoma, and Hodgkin’s disease. Although a cause and effect relationship has not been established, the occurrence of lymphadenopathy indicates the need to differentiate such a condition from other types of lymph node pathology. Lymph node involvement may occur with or without symptoms and signs resembling serum sickness, eg, fever, rash, and liver involvement.

In all cases of lymphadenopathy, follow-up observation for an extended period is indicated and every effort should be made to achieve seizure control using alternative antiepileptic drugs.

Acute alcoholic intake may increase phenytoin serum levels, while chronic alcoholic use may decrease serum levels.

In view of isolated reports associating phenytoin with exacerbation of porphyria, caution should be exercised in using this medication in patients suffering from this disease.

Usage In Pregnancy

Clinical:

Risks to Mother. An increase in seizure frequency may occur during pregnancy because of altered phenytoin pharmacokinetics. Periodic measurement of plasma phenytoin concentrations may be valuable in the management of pregnant women as a guide to appropriate adjustment of dosage (see PRECAUTIONS, Laboratory Tests). However, postpartum restoration of the original dosage will probably be indicated.
Risks to the Fetus. If this drug is used during pregnancy, or if the patient becomes pregnant while taking the drug, the patient should be apprised of the potential harm to the fetus.

Prenatal exposure to phenytoin may increase the risks for congenital malformations and other adverse developmental outcomes. Increased frequencies of major malformations (such as orofacial clefts and cardiac defects), minor anomalies (dysmorphic facial features, nail and digit hypoplasia), growth abnormalities (including microcephaly), and mental deficiency have been reported among children born to epileptic women who took phenytoin alone or in combination with other antiepileptic drugs during pregnancy. There have also been several reported cases of malignancies, including neuroblastoma, in children whose mothers received phenytoin during pregnancy. The overall incidence of malformations for children of epileptic women treated with antiepileptic drugs (phenytoin and/or others) during pregnancy is about 10%, or two- to three-fold that in the general population. However, the relative contributions of antiepileptic drugs and other factors associated with epilepsy to this increased risk are uncertain and in most cases it has not been possible to attribute specific developmental abnormalities to particular antiepileptic drugs. Patients should consult with their physicians to weigh the risks and benefits of phenytoin during pregnancy.
Postpartum Period. A potentially life-threatening bleeding disorder related to decreased levels of vitamin K-dependent clotting factors may occur in newborns exposed to phenytoin in utero. This drug-induced condition can be prevented with vitamin K administration to the mother before delivery and to the neonate after birth.

Preclinical:

Increased resorption and malformation rates have been reported following administration of phenytoin doses of 75 mg/kg or higher (approximately 120% of the maximum human loading dose or higher on a mg/m2 basis) to pregnant rabbits.

Serum concentrations should be monitored and care should be taken when switching a patient from the sodium salt to the free acid form. The free acid form of phenytoin is used in phenytoin oral suspension and chewable tablets. All other phenytoin products are formulated with the sodium salt. Because there is approximately an 8% increase in drug content with the free acid form over that of the sodium salt, dosage adjustments and serum level monitoring may be necessary when switching from a product formulated with the free acid to a product formulated with the sodium salt and vice versa.

General:Dosage should be individualized to provide maximum benefit. In some cases serum blood level determinations may be necessary for optimal dosage adjustments – the clinically effective serum level is usually 10-20 mcg/mL. With recommended dosage, a period of seven to ten days may be required to achieve steady-state blood levels with phenytoin and changes in dosage (increase or decrease) should not be carried out at intervals shorter than seven to ten days.

Adult Dose: Patients who have received no previous treatment may be started on one teaspoonful (5 mL) of phenytoin oral suspension three times daily, and the dose is then adjusted to suit individual requirements. An increase to five teaspoonfuls daily may be made, if necessary.

Pediatric Dose: Initially, 5 mg/kg/day in two or three equally divided doses, with subsequent dosage individualized to a maximum of 300 mg daily. A recommended daily maintenance dosage is usually 4 to 8 mg/kg. Children over 6 years and adolescents may require the minimum adult dose (300 mg/day).

The recommended dose of Meropenem for Injection USP and Sodium Chloride Injection USP is 500 mg given every 8 hours for skin and skin structure infections and 1 gram given every 8 hours for intra-abdominal infections. When treating complicated skin and skin structure infections caused by P. aeruginosa, a dose of 1 gram every 8 hours is recommended.

Meropenem for Injection USP and Sodium Chloride Injection USP should be administered by intravenous infusion over approximately 15 to 30 minutes.
2.2 Use in Adult Patients with Renal Impairment
Dosage should be reduced in patients with creatinine clearance of 50 mL/min or less. (See dosing table below.)

Dosage should be reduced in renal failure if less than a full dose (1 gram or 500 mg) is required and an alternative formulation should be used to avoid risk of overdose.

When only serum creatinine is available, the following formula (Cockcroft and Gault equation)5 may be used to estimate creatinine clearance.

Males: Creatinine Clearance (mL/min) =
Weight (kg) x (140 - age) 72 x serum creatinine (mg/dL)
Females: 0.85 x above value

Creatinine Clearance (mL/min) Dose (dependent on type of infection) Dosing Interval greater than 50 Recommended dose (500 mg cSSSI and 1 gram Intra-abdominal infection) Every 8 hours greater than 25-50 Recommended dose Every 12 hours 10-25 One-half recommended dose Every 12 hours less than 10 One-half recommended dose Every 24 hours
There is inadequate information regarding the use of meropenem for injection in patients on hemodialysis or peritoneal dialysis.
2.3 Use in Pediatric Patients (3 Months of age and older only)
Meropenem for Injection USP and Sodium Chloride Injection USP in the DUPLEX® Container is designed to deliver a 500 mg or 1 gram dose of meropenem. To prevent unintentional overdose, this product should not be used in pediatric patients who require less than the full adult dose of meropenem. Meropenem is not to be used in pediatric patients aged less than three months. There is no experience in pediatric patients with renal impairment. (See dosing table below.) [see Use in Specific Populations (8.4)].

Pediatric patients weighing over 50 kg should be administered Meropenem for Injection USP and Sodium Chloride Injection USP at a dose of 500 mg every 8 hours for complicated skin and skin structure infections, 1 gram every 8 hours for intra-abdominal infections and 2 grams every 8 hours for meningitis. Meropenem for Injection USP and Sodium Chloride Injection USP should be given as intravenous infusion over approximately 15 to 30 minutes.

2.4 Preparation and Administration of Meropenem for Injection USP and Sodium Chloride Injection USP in DUPLEX® Container
This reconstituted solution is for intravenous use only.

Do not use plastic containers in series connections. Such use would result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is complete. If administration is controlled by a pumping device, care must be taken to discontinue pumping action before the container runs dry or air embolism may result.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Use only if solution is clear and container and seals are intact.

DUPLEX® Container Storage
To avoid inadvertent activation, the DUPLEX® Container should remain in the folded position until activation is intended.
Patient Labeling and Drug Powder/Diluent Inspection
Apply patient-specific label on foil side of container. Use care to avoid activation. Do not cover any portion of foil strip with patient label. Unlatch side tab and unfold DUPLEX® Container (see Diagram 1). Visually inspect diluent chamber for particulate matter. Use only if container and seals are intact. To inspect the drug powder for foreign matter or discoloration, peel foil strip from drug chamber (see Diagram 2). Protect from light after removal of foil strip.
Note: If foil strip is removed, the container should be re-folded and the side tab latched until ready to activate. The product must then be used within 7 days at room temperature, but not beyond the labeled expiration date.

Reconstitution (Activation)
Do not use directly after storage by refrigeration, allow the product to equilibrate to room temperature before patient use. Unfold the DUPLEX® Container and point the set port in a downward direction. Starting at the hanger tab end, fold the DUPLEX® Container just below the diluent meniscus trapping all air above the fold. To activate, squeeze the folded diluent chamber until the seal between the diluent and powder opens, releasing diluent into the drug powder chamber (see Diagram 3). Agitate the liquid-powder mixture until the drug powder is completely dissolved.
Note: Following reconstitution (activation), product must be used within 1 hour if stored at room temperature or within 15 hours if stored under refrigeration.

Administration
Visually inspect the reconstituted solution for particulate matter. Point the set port in a downwards direction. Starting at the hanger tab end, fold the DUPLEX® Container just below the solution meniscus trapping all air above the fold. Squeeze the folded DUPLEX® Container until the seal between reconstituted drug solution and set port opens, releasing liquid to set port (see Diagram 4). Prior to attaching the IV set, check for minute leaks by squeezing container firmly. If leaks are found, discard container and solution as sterility may be compromised. Using aseptic technique, peel foil cover from the set port and attach sterile administration set (see Diagram 5). Refer to directions for use accompanying the administration set.
Important Administration Instructions
Do not use in series connections. Do not introduce additives into the DUPLEX® Container. Administer Meropenem for Injection USP and Sodium Chloride Injection USP intravenously over approximately 15 to 30 minutes. 2.5 Compatibility
