Discuss the risks and benefits with your doctor. DOSAGE MUST BE INDIVIDUALIZED. The recommended initial dosage is 100 mg twice daily whether used alone or added to a diuretic regimen. After 2 or 3 days, using standing blood pressure as an indicator, dosage may be titrated in increments of 100 mg twice daily every 2 or 3 days. The usual maintenance dosage of labetalol HCl is between 200 mg and 400 mg twice daily. These glands make hormones, chemicals that help control how your body works. They affect things like hair growth, blood pressure, your sex drive, and even how you handle stress. When you have adrenal cancer, you might notice changes in these areas.
Should side effects principally nausea or dizziness occur with these doses administered twice daily, the same total daily dose administered three times daily may improve tolerability and facilitate further titration. Titration increments should not exceed 200 mg twice daily. When a diuretic is added, an additive antihypertensive effect can be expected. In some cases this may necessitate a labetalol HCl dosage adjustment. As with most antihypertensive drugs, optimal dosages of labetalol HCl tablets are usually lower in patients also receiving a diuretic. When transferring patients from other antihypertensive drugs, labetalol HCl tablets should be introduced as recommended and the dosage of the existing therapy progressively decreased.
Generic drugs: Labetalol hydrochloride, by various manufacturers. The incidence of adverse reactions depends upon the dose of labetalol HCl. The largest experience is with oral labetalol HCl see labetalol HCl tablet product information for details. Do not share this medication with others. In patients with latent cardiac insufficiency, continued depression of the myocardium with beta-blocking agents over a period of time can, in some cases, lead to cardiac failure.
Labetalol has been shown to cross the placental barrier in humans. Only negligible amounts of the drug crossed the blood-brain barrier in animal studies. Labetalol is approximately 50% protein bound. This medicine makes me feel worse than my high blood pressure and it doesn't bring it down enough for me to feel like this. Dizzy, light-headed, constipated, headache, and just an overall feeling of yuck. I have been taking 200mg 2x daily for the past month and a half. Since the half-life of this drug is 5 to 8 hours, steady-state blood levels in the face of a constant rate of infusion would not be reached during the usual infusion time period; the infusion should be continued until a satisfactory response is obtained and should then be stopped and the oral formulation should be started.
This drug is not removed by hemodialysis or peritoneal dialysis; a supplemental dose is not needed. When labetalol is given in acute situations, it decreases the peripheral vascular resistance and systemic blood pressure while having little effect on the heart rate, cardiac output and stroke volume, despite its alpha1-, beta1- and beta2- blocking mechanism. These effects are mainly seen when the person is in the upright position. Chronic Bronchitis and Emphysema: Patients with bronchospastic disease should, in general, not receive beta-blockers. Labetalol Hydrochloride Tablets may be used with caution, however, in patients who do not respond to, or cannot tolerate, other antihypertensive agents. It is prudent, if Labetalol Hydrochloride Tablets are used, to use the smallest effective dose, so that inhibition of endogenous or exogenous beta-agonists is minimized. Rate of infusion: The rate of infusion of the diluted solution may be adjusted according to the blood pressure response, at the discretion of the physician. As in the general patient population, labetalol therapy may be initiated at 100 mg twice daily and titrated upwards in increments of 100 mg twice daily as required for control of blood pressure. Since some elderly patients eliminate labetalol more slowly, however, adequate control of blood pressure may be achieved at a lower maintenance dosage compared to the general population. The majority of elderly patients will require between 100 mg and 200 mg twice daily. When a diuretic is added, an additive antihypertensive effect can be expected. In some cases this may necessitate a labetalol HCl dosage adjustment. As with most antihypertensive drugs, optimal dosages of labetalol HCl tablets are usually lower in patients also receiving a diuretic.

Steady-state plasma levels of labetalol during repetitive dosing are reached by about the third day of dosing. In patients with decreased hepatic or renal function, the elimination half-life of labetalol is not altered; however, the relative bioavailability in hepatically impaired patients is increased due to decreased “first-pass” metabolism. FDA pregnancy category C. It is not known whether labetalol will harm an unborn baby. Labetalol may cause heart or lung problems in a newborn if the mother takes the medication during pregnancy. Tell your doctor if you are pregnant or plan to become pregnant while using this medication. Subsequent oral dosing with labetalol hydrochloride tablets should begin when it has been established that the supine diastolic blood pressure has begun to rise. Immediately before the injection and at 5 and 10 minutes after injection, supine blood pressure should be measured to evaluate response. Additional injections of 40 or 80 mg can be given at 10-minute intervals until a desired supine blood pressure is achieved or a total of 300 mg of labetalol HCl has been injected. If your doctor has prescribed this medication, read the Patient Information Leaflet if provided by your before you start using this product and each time you get a refill.

The hepatic injury is usually reversible, but hepatic necrosis and death have been reported. Injury has occurred after both short- and long-term treatment and may be slowly progressive despite minimal symptomatology. Similar hepatic events have been reported with a related research compound, dilevalol HCl, including two deaths. Dilevalol HCl is one of the four isomers of labetalol HCl.

Labetalol HCl is completely absorbed from the gastrointestinal tract with peak plasma levels occurring 1 to 2 hours after oral administration. The relative bioavailability of labetalol HCl tablets compared to an oral solution is 100%. The absolute bioavailability fraction of drug reaching systemic circulation of labetalol when compared to an intravenous infusion is 25%; this is due to extensive “first-pass” metabolism. Despite “first-pass” metabolism, there is a linear relationship between oral doses of 100 to 3000 mg and peak plasma levels. The absolute bioavailability of labetalol is increased when administered with food. Tell your doctor if your condition does not improve or if it worsens for example, your blood pressure readings remain high or increase. Although beta-adrenergic receptor blockade is useful in the treatment of angina and hypertension, there are also situations in which sympathetic stimulation is vital. For example, in patients with severely damaged hearts, adequate ventricular function may depend on sympathetic drive. Beta-adrenergic blockade may worsen A-V block by preventing the necessary facilitating effects of sympathetic activity on conduction. Beta 2-adrenergic blockade results in passive bronchial constriction by interfering with endogenous adrenergic bronchodilator activity in patients subject to bronchospasm, and it may also interfere with exogenous bronchodilators in such patients. Store at room temperature away from moisture and heat. Synergism has been shown between halothane anesthesia and intravenously administered labetalol HCl. During controlled hypotensive anesthesia using labetalol HCl in association with halothane, high concentrations 3% or above of halothane should not be used because the degree of hypotension will be increased and because of the possibility of a large reduction in cardiac output and an increase in central venous pressure. The anesthesiologist should be informed when a patient is receiving labetalol HCl. For the treatment of high blood pressure, it may take several weeks before you get the full benefit of this drug.

The patient's ability to tolerate an upright position should be established before permitting any ambulation, such as using toilet facilities. Labetalol is used to treat hypertension high blood pressure. Since the full antihypertensive effect of labetalol is usually seen within the first 1 to 3 hours of the initial dose or dose increment, the assurance of a lack of an exaggerated hypotensive response can be clinically established in the office setting. The antihypertensive effects of continued dosing can be measured at subsequent visits, approximately 12 hours after a dose, to determine whether further titration is necessary. Either of two methods of administration of labetalol hydrochloride injection may be used: a repeated IV injection, or b slow continuous infusion. The minimum requirement for is a primary or secondary amine separated from a substituted benzene ring by one or two carbons. This configuration results in strong agonist activity. As the size of the substituent attached to the amine becomes greater, particularly with respect to a t-butyl group, then the molecule typically is found to have without intrinsic activity, and is, therefore, an antagonist. Labetalol, with its 1-methyl-3-phenylpropyl substituted amine, is greater in size relative to a t-butyl group and therefore acts predominantly as an antagonist. The overall structure of labetalol is very polar. This was created by substituting the isopropyl group in the standard beta-blocker structure with an aralkyl group, including a carboxamide group on the meta position, and by adding a hydroxyl group on the para position. Labetalol HCl is a white or off-white crystalline powder, soluble in water. Due to the alpha 1-receptor blocking activity of labetalol HCl, blood pressure is lowered more in the standing than in the supine position, and symptoms of postural hypotension can occur. During dosing with IV labetalol HCl, the contribution of the postural component should be considered when positioning the patient for treatment, and the patient should not be allowed to move to an erect position unmonitored until his ability to do so is established. This medicine makes me feel worse than my high blood pressure and it doesn't bring it down enough for me to feel like this.

The effective intravenous dose is usually in the range of 50 to 200 mg. A total dose of up to 300 mg may be required in some patients. Katzung, Bertram G. 2006. Basic and clinical pharmacology. New York: McGraw-Hill Medical. Intravenous labetalol HCl has been shown to be effective in lowering blood pressure and relieving symptoms in patients with pheochromocytoma; higher than usual doses may be required. However, paradoxical hypertensive responses have been reported in a few patients with this tumor; therefore, use caution when administering labetalol HCl to patients with pheochromocytoma. Labetalol HCl produces dose-related falls in blood pressure without reflex tachycardia and without significant reduction in heart rate, presumably through a mixture of its alpha- and beta-blocking effects. Hemodynamic effects are variable, with small, nonsignificant changes in cardiac output seen in some studies but not others, and small decreases in total peripheral resistance. Elevated plasma renins are reduced. Among patients dosed with labetalol hydrochloride tablets, there have been reversible increases of serum transaminases in 4% of patients tested and, more rarely, reversible increases in blood urea.

However, hypersensitivity to catecholamines has been observed in patients withdrawn from beta-blocker therapy; exacerbation of angina and, in some cases, myocardial infarction have occurred after abrupt discontinuation of such therapy. When discontinuing chronically administered labetalol HCl tablets, particularly in patients with ischemic heart disease, the dosage should be gradually reduced over a period of 1 to 2 weeks and the patient should be carefully monitored. If angina markedly worsens or acute coronary insufficiency develops, therapy with labetalol HCl tablets should be reinstituted promptly, at least temporarily, and other measures appropriate for the management of unstable angina should be taken.
Cardiovascular: Intensification of A-V block see CONTRAINDICATIONS. Teratogenic studies were performed with labetalol in rats and rabbits at oral doses up to approximately six and four times the maximum recommended human dose MRHD respectively. No reproducible evidence of fetal malformations was observed. Increased fetal resorptions were seen in both species at doses approximating the MRHD. Labetalol hydrochloride injection should be used with caution in patients with impaired hepatic function since metabolism of the drug may be diminished. Exacerbation of angina and, in some cases, myocardial infarction and ventricular dysrhythmias have been reported after abrupt discontinuation of therapy with beta-adrenergic blocking agents in patients with coronary artery disease. Abrupt withdrawal of these agents in patients without coronary artery disease has resulted in transient symptoms, including tremulousness, sweating, palpitation, headache, and malaise. Several mechanisms have been proposed to explain these phenomena, among them increased sensitivity to catecholamines because of increased numbers of beta receptors.
