Newly
added subsection:
5.2

5.3 Contamination of
Topical Ophthalmic Products After Use
There
have been reports of bacterial keratitis associated with the use of
multiple-dose containers of topical ophthalmic products. These containers had

6.2
Postmarketing Experience
Additions
and/or revisions underlined:
The
following adverse reactions have been identified during postapproval
use of brimonidine tartrate ophthalmic solution. Because these reactions are
reported voluntarily from a population of uncertain size, it is not
always possible to reliably estimate their frequency or establish a causal
relationship to drug exposure.
- Bradycardia,
iritis, miosis, skin reactions (including erythema, eyelid pruritis, rash, and
vasodilation), and tachycardia.
- Apnea,
bradycardia, hypotension, hypothermia, hypotonia, and somnolence have been
reported in infants receiving brimonidine tartrate ophthalmic solutions.

Use in Specific Populations
8.1
Pregnancy
PLLR
conversion:
Risk
Summary
There
are no adequate and well-controlled studies with brimonidine tartrate ophthalmic
solution, 0.15% in pregnant women. In the U.S. general population, the
estimated background risk of major birth defects and miscarriage in clinically
recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
In
animal studies, brimonidine crossed the placenta and entered into the fetal
circulation to a limited extent (see
Data). Because animal reproduction studies are not always predictive of
human response, brimonidine tartrate ophthalmic solution, 0.15% should be used
during pregnancy only if the potential benefit to the mother justifies the
potential risk to the fetus.
Data
Human Data
Limited
available data from postmarketing safety reports and published literature with
topical use of brimonidine tartrate ophthalmic solution in pregnant women are
insufficient to inform a drug-associated risk of pregnancy-related adverse
outcomes including miscarriage, stillbirth, congenital anomaly, and events
experiences by offspring while breastfeeding.
Animal Data
Embryofetal
studies were conducted in pregnant rabbits administered brimonidine tartrate by
daily oral gavage on gestation days 6 to 18, to target the period of
organogenesis. Brimonidine caused miscarriage at 5 mg/kg/day (approximately
50-times the recommended human ophthalmic dose (RHOD) based on AUC). The no
observed adverse effect level (NOAEL) for developmental toxicity in rabbits was
1 mg/kg/day (approximately 6-fold the RHOD based on AUC). No treatment-related
malformations were observed in rabbits. Signs of maternal sedation and fatigue
were observed at all dose levels; the lowest observed adverse effect level
(LOAEL) for maternal toxicity was 5 mg/kg/day, based on the dose-response for
these signs.
Embryofetal
studies were conducted in pregnant rats administered brimonidine tartrate by
daily oral gavage on gestation days 6 to 15, to target the period of
organogenesis. The NOAEL for developmental toxicity was 2.5 mg/kg/day
(approximately 750-fold the RHOD based on AUC). No treatment-related
malformations were observed in rats. The LOAEL for maternal toxicity was 2.5
mg/kg/day, based on signs of sedation and fatigue. The maternal NOAEL was 1
mg/kg/day (180-fold the RHOD based on AUC).
After
pregnant rats received a single oral dose of 14C-brimonidine tartrate,
brimonidine and metabolites crossed the placenta and were detectable in fetal
blood and organs.
8.2
Lactation
PLLR
conversion:
Risk
Summary
It
is not known whether brimonidine tartrate is excreted in human milk. In animal
studies, brimonidine has been shown to cross the blood-brain barrier and is
excreted into breast milk after oral administration to lactating rats (see Data). Because of the potential for
serious adverse reactions, including central nervous system depression and
apnea, from brimonidine tartrate ophthalmic solution, 0.15% in nursing infants,
brimonidine tartrate ophthalmic solution, 0.15% is not recommended for use
during lactation.
Data
Animal Data
After
a single oral dose of 14C-labeled brimonidine tartrate to lactating rats,
brimonidine and metabolites were detected in milk. After male and female rats
received a single oral dose of 14C-brimonidine tartrate, brimonidine crossed
the blood:brain barrier. Radiolabel was detected in the cerebellum, cerebrum,
and spinal cord.
8.4
Pediatric Use
Additions
and/or revisions underlined:
Brimonidine
tartrate ophthalmic solution, 0.15% is contraindicated in pediatric patients
younger than 2 years old [see
Contraindications (4.1)]. During postmarketing
surveillance, apnea, bradycardia, coma, hypotension, hypothermia, hypotonia,
lethargy, pallor, respiratory depression, and somnolence have been reported in
infants receiving brimonidine.
In
a well-controlled clinical study conducted in pediatric glaucoma patients aged
2 to 7 years old, the most commonly observed adverse events with
brimonidine tartrate ophthalmic solution 0.2% dosed three-times- daily were
somnolence (50% to 83% in pediatric patients aged 2 to 6 years old)
and decreased alertness. In pediatric patients aged 7 years and older
(>20 kg), somnolence appears to occur less frequently (25%).
Approximately
16% of pediatric patients on brimonidine tartrate ophthalmic solution
discontinued from the study due to somnolence.

PATIENT
COUNSELING INFORMATION
Additions
and/or revisions underlined:
Handling
the Container
Instruct
patients that ocular solutions, if handled improperly or if the tip of the
dispensing container contacts the eye or surrounding structures, can become
contaminated by common bacteria known to cause ocular infections. Serious
damage to the eye and subsequent loss of vision may result from using
contaminated solutions [see Warnings and
Precautions (5.3)]. Always replace the cap after
using. If solution changes color or becomes cloudy, do not use. Do not use the
product after the expiration date marked on the bottle.
When
to Seek Physician Advice
Advise
patients that if they have ocular surgery or develop an intercurrent ocular
condition (e.g., trauma or infection), they should immediately seek their
physician's advice concerning the continued use of the present multidose
container.
Use
with Other Ophthalmic Drugs
Advise
patients that if more than one topical ophthalmic drug is being used, the drugs
should be administered at least five minutes apart.
Potential
for Decreased Mental Alertness
As with other drugs in this class,
brimonidine tartrate ophthalmic solution, 0.15% may cause fatigue and/or
drowsiness in some patients. Patients who engage in hazardous activities should
be cautioned of the potential for a decrease in mental alertness.
