Warnings and Precautions
5.6 Masked Symptoms of Hypoglycemia
Newly added information:
Beta-blockers may prevent early
warning signs of hypoglycemia, such as tachycardia, and increase the
risk for severe or prolonged hypoglycemia at anytime during treatment,
especially in patients with diabetes mellitus or children and patients who are
fasting (i.e., surgery, not eating regularly, or are vomiting). If severe
hypoglycemia occurs, patients should
be instructed to seek emergency treatment.

PATIENT COUNSELING INFORMATION
Newly added information:
Inform patients or caregivers that there is a risk of hypoglycemia when Lopressor HCT is given to
patients who are fasting or who are vomiting. Instruct patients or caregivers
how to monitor for signs of hypoglycemia [see
Warnings and Precautions (5.6)].

Summary
There
are no data on the presence of LOPRESSOR HCT in human milk, the effects on the
breastfed infant, or the effects on milk production. However, data are
available on the individual components of LOPRESSOR HCT. Available data from published literature on metoprolol and
hydrochlorothiazide report that each drug is present in human milk (see Data). There are no reports of
adverse effects on breastfed infants exposed to metoprolol or
hydrochlorothiazide during lactation. Doses of hydrochlorothiazide associated
with clinically significant diuresis have been associated with impaired milk
production. There is no information regarding the effects of metoprolol on milk
production. Monitor infants exposed to LOPRESSOR HCT though breastmilk for
drowsiness or poor feeding (see Clinical
Considerations).
The
developmental and health benefits of breastfeeding should be considered along
with the mother’s clinical need for LOPRESSOR HCT and any potential adverse
effects on the breastfed child from LOPRESSOR HCT or from the underlying
maternal condition.
Clinical
Considerations
Monitor
the breastfed infant for bradycardia or somnolence. Data
Metoprolol
Based
on published case reports, the estimated daily infant dose of metoprolol
received from breastmilk ranged from 0.05 mg to less than 1 mg. The estimated
relative infant dosage was 0.5% to 2% of the mother’s weight-adjusted dosage.
In
two women who were taking unspecified amount of metoprolol, milk samples were
taken after one dose of metoprolol. The estimated amount of metoprolol and
alpha-hydroxymetoprolol in breast milk is reported to be less than 2% of the
mother's weight-adjusted dosage.
In
a small study, breast milk was collected every 2 to 3 hours over one dosage
interval, in three mothers (at least 3 months postpartum) who took metoprolol
of unspecified amount. The average amount of metoprolol present in breast milk
was 71.5 mcg/day (range 17.0 to 158.7). The average relative infant dosage was
0.5% of the mother's weight-adjusted dosage.
Hydrochlorothiazide
A
single study involving one woman and her infant showed a peak concentration of
275 mcg/L at 3 hours following 50 mg dose. No drug was detected (< 20 mcg/L)
in the infant’s plasma at 2 and 11 hours following mother’s dose.

Males of Reproductive Potential

Infertility
Males
Based
on the published literature, beta blockers (including metoprolol) may cause
erectile dysfunction and inhibit sperm motility. No evidence of impaired
fertility due to metoprolol or hydrochlorothiazide was observed in rats [see Nonclinical Toxicology (13.1)].

PATIENT COUNSELING INFORMATION
New
section added
Advise
patients to take Lopressor HCT as directed, with or immediately following
meals. If a dose is missed, advise the patient to take only the next scheduled
dose (without doubling it). Advise patients to not discontinue Lopressor HCT
without consulting their healthcare provider.

Adverse Reactions
Postmarketing Experience
Newly added information:
Non-melanoma Skin Cancer: Hydrochlorothiazide
is associated with an increased risk of non- melanoma skin cancer. In a study
conducted in the Sentinel System, increased risk was predominantly for squamous
cell carcinoma (SCC) and in white patients taking large cumulative doses. The
increased risk for SCC in the overall population was approximately 1 additional
case per 16,000 patients per year, and for white patients taking a cumulative
dose of greater than or equal to 50,000mg the risk increase was approximately 1
additional SCC case for every 6,700 patients per year.
