Medical uses
[edit]It has a particular indication in the treatment of pregnancy-induced hypertension which is commonly associated with pre-eclampsia [1]
Labetalol is effective in the management of hypertensive emergencies, postoperative hypertension, pheochromocytoma-associated hypertension, and rebound hypertension from beta blocker withdrawal. It can also be used as an alternative in the treatment of severe hypertension. [2]
Use in specific populations
[edit]- Pregnancy: Pregnancy Category C. Labetalol is an acceptable treatment in pregnant women with hypertension. [3]Because labetalol can cross placenta, it should be used during pregnancy only if the benefits to the mother outweigh the risks to the fetus.[4]
- Labor and delivery: labetalol does not affect labor and delivery when given to pregnant patients with hypertension.
- Lactation: a small amount of labetalol (approximately 0.004% of maternal dose) reaches the fetus via breast milk. Caution is needed when administering labetalol to nursing mothers.[4]
- In children: although there’s a lack of established documentation on safety and effectiveness in pediatric patients, it is recommended that labetalol was carefully initiated and properly adjusted with blood pressure monitoring in this patient population.
- In the elderly: because elderly patients are more likely to experience orthostatic hypotension, dizziness, and lightheadedness, they should be warned about the possibility of such side effects during treatment with labetalol. [4]
