id="LM625.Summary_of_Use_during_Lactation"><h3>Summary of Use during Lactation</h3><p>No data are available for the use of carteolol during breastfeeding. Because its excretion into breastmilk is probably extensive, other beta-adrenergic blocking drugs are preferred to oral carteolol while breastfeeding a neonate. Infants over 2 months of age have more mature kidney function and are less likely to be affected.</p><p>Ophthalmic use of carteolol by the mother should pose little risk to the breastfed infant, although some guidelines state that gel formulations are preferred over solutions.[<a class="bibr" href="#LM625.REF.1" rid="LM625.REF.1">1</a>,<a class="bibr" href="#LM625.REF.2" rid="LM625.REF.2">2</a>] To substantially diminish the amount of drug that reaches the breastmilk after using eye drops, place pressure over the tear duct by the corner of the eye for 1 minute or more, then remove the excess solution with an absorbent tissue.</p></div><div id="LM625.Drug_Levels"><h3>Drug Levels</h3><p>The excretion of beta-adrenergic blocking drugs into breastmilk is largely determined by their protein binding. Those with low binding are more extensively excreted into breastmilk.[<a class="bibr" href="#LM625.REF.3" rid="LM625.REF.3">3</a>] Accumulation of the drugs in the infant is related to the fraction excreted in urine. With 60% protein binding, 15% renal excretion and a moderately long half-life, carteolol presents a relatively high risk for accumulation in infants, especially neonates.</p><p><i>Maternal Levels.</i> Relevant published information was not found as of the revision date.</p><p><i>Infant Levels.</i> Relevant published information was not found as of the revision date.</p></div><div id="LM625.Effects_in_Breastfed_Infants"><h3>Effects in Breastfed Infants</h3><p>A study of mothers taking beta-blockers during nursing found a numerically, but not statistically significant increased number of adverse reactions in those taking any beta-blocker.

None of the mothers were taking carteolol.[<a class="bibr" href="#LM625.REF.4" rid="LM625.REF.4">4</a>] Beta-adrenergic blocking drugs with similar breastmilk excretion characteristics have caused adverse effects in breastfed newborns.[<a class="bibr" href="#LM625.REF.5" rid="LM625.REF.5">5</a>,<a class="bibr" href="#LM625.REF.6" rid="LM625.REF.6">6</a>]</p></div><div id="LM625.Effects_on_Lactation_and_Breastmil"><h3>Effects on Lactation and Breastmilk</h3><p>A study in 6 patients with hyperprolactinemia and galactorrhea found no changes in serum prolactin levels following beta-adrenergic blockade with propranolol.[<a class="bibr" href="#LM625.REF.7" rid="LM625.REF.7">7</a>] There are no reports on the effects of beta-blockade or carteolol use during normal lactation.</p></div><div id="LM625.Alternate_Drugs_to_Consider"><h3>Alternate Drugs to Consider</h3><p>(Systemic) <a href="/books/n/lactmed/LM301/?report=reader">Propranolol</a>, <a href="/books/n/lactmed/LM291/?report=reader">Labetalol</a>, <a href="/books/n/lactmed/LM296/?report=reader">Metoprolol</a>; (Ophthalmic) <a href="/books/n/lactmed/LM292/?report=reader">Levobunolol</a>, <a href="/books/n/lactmed/LM295/?report=reader">Metipranolol</a>, <a href="/books/n/lactmed/LM305/?report=reader">Timolol</a></p></div><div id="LM625.References"><h3>References</h3><dl class="temp-labeled-list"><dl class="bkr_refwrap"><dt>1.</dt><dd><div class="bk_ref" id="LM625.REF.1">Belkin
