This can lead to heart attacks, kidney failure, stroke or blindness. Use Trandate with caution in the ELDERLY; they may be more sensitive to its effects, especially dizziness, lightheadedness, or fainting. Body as a Whole: Fever. Pharmacokinetics and Metabolism: 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.
Food and Drug Administration. WebMD does not endorse any specific product, service, or treatment. 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.
Other symptoms of a low blood sugar level, such as dizziness and sweating, are unaffected by this drug. This product may also make it harder to control your blood sugar levels. Check your blood sugar levels regularly as directed by your doctor. There is pharmacologic evidence that norepinephrine may be the drug of choice. Tablets Product Information for details.

Only negligible amounts of the drug crossed the blood-brain barrier in animal studies. Labetalol is approximately 50% protein bound. The incidence rates of adverse reactions listed in the following table were derived from multicenter, controlled clinical trials comparing labetalol HCl, placebo, metoprolol, and propranolol over treatment periods of 3 and 4 months. Where the frequency of adverse effects for labetalol HCl and placebo is similar, causal relationship is uncertain. The rates are based on adverse reactions considered probably drug related by the investigator. About FAERS: The FDA Adverse Event Reporting System FAERS is used by FDA for activities such as looking for new safety concerns that might be related to a marketed product, evaluating a manufacturer's compliance to reporting regulations and responding to outside requests for information. Reporting of adverse events is a voluntary process, and not every report is sent to FDA and entered into FAERS. Clinical Laboratory Tests: Among patients dosed with TRANDATE Tablets, there have been reversible increases of serum transaminases in 4% of patients tested and, more rarely, reversible increases in blood urea. This drug crosses the placental barrier and has been found to bind to the eyes of fetal animals.

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 2% including rare instances of syncope, can occur. Following oral administration, when postural hypotension has occurred, it has been transient and is uncommon when the recommended starting dose and titration increments are closely followed see . Symptomatic postural hypotension is most likely to occur 2 to 4 hours after a dose, especially following the use of large initial doses or upon large changes in dose.

Pregnancy: Teratogenic Effects: Pregnancy Category C: 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. Exacerbation of Ischemic Heart Disease Following Abrupt Withdrawal: Angina pectoris has not been reported upon labetalol HCl discontinuation. 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. If the patient has laboratory evidence of liver injury or jaundice, labetalol should be stopped and not restarted. Care should be taken if labetalol is used concomitantly with calcium antagonists of the verapamil type. Injury to the scalp, including scarring.

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. There is usually mounting tension before pulling and a feeling of relief afterward. often results in noticeable hair loss. This medication is both an alpha blocker and beta blocker. It works by blocking the action of certain natural chemicals in your body such as epinephrine on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart. Pharmacodynamics: The capacity of labetalol HCl to block alpha receptors in man has been demonstrated by attenuation of the pressor effect of phenylephrine and by a significant reduction of the pressor response caused by immersing the hand in ice-cold water "cold-pressor test". Labetalol HCl's beta 1-receptor blockade in man was demonstrated by a small decrease in the resting heart rate, attenuation of tachycardia produced by isoproterenol or exercise, and by attenuation of the reflex tachycardia to the hypotension produced by amyl nitrite. Beta 2-receptor blockade was demonstrated by inhibition of the isoproterenol-induced fall in diastolic blood pressure. Both the alpha- and beta-blocking actions of orally administered labetalol HCl contribute to a decrease in blood pressure in hypertensive patients. Labetalol HCl consistently, in dose-related fashion, blunted increases in exercise-induced blood pressure and heart rate, and in their double product. The pulmonary circulation during exercise was not affected by labetalol HCl dosing. Beta-adrenergic receptor blocking agents aka beta-blockers in general should not be used in patients with overt congestive heart failure CHF. Sympathetic stimulation may be important in maintaining the hemodynamic function in these patients, thus beta-blockade can worsen the heart failure.

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. Impaired Hepatic Function: Trandate Tablets should be used with caution in patients with impaired hepatic function since metabolism of the drug may be diminished.
