Labetalol hydrochloride injection is prepared for continuous IV infusion by diluting the vial contents with commonly used IV fluids see below. 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.
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. This drug may reduce blood flow to your hands and feet, causing them to feel cold. Smoking may worsen this effect. Dress warmly and avoid tobacco use. 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.

Cardiovascular: Intensification of A-V block see CONTRAINDICATIONS. 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. Alternatively, 200 mg of labetalol hydrochloride injection is added to 250 mL of a commonly used intravenous fluid. Ask your pharmacist about using those products safely.

As in the general population, some elderly patients 60 years of age and older have experienced orthostatic hypotension, dizziness, or lightheadedness during treatment with labetalol. Because elderly patients are generally more likely than younger patients to experience orthostatic symptoms, they should be cautioned about the possibility of such side effects during treatment with labetalol. HCl has been injected. Hematologic: Agranulocytosis, thrombocytopenic or nonthrombocytopenic purpura. Hepatic Injury: Severe hepatocellular injury, confirmed by rechallenge in at least one case, occurs rarely with therapy with labetalol therapy. 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. Thus, for patients taking labetalol, periodic determination of suitable hepatic laboratory tests would be appropriate. Overdosage with labetalol HCl causes excessive hypotension that is posture sensitive and, sometimes, excessive bradycardia. Patients should be placed supine and their legs raised if necessary to improve the blood supply to the brain. If overdosage with labetalol HCl follows oral ingestion, gastric lavage or pharmacologically induced emesis using syrup of ipecac may be useful for removal of the drug shortly after ingestion.

Drinking alcohol can further lower your blood pressure and may increase certain side effects of labetalol. F. Protect from freezing. 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. Patients with severe hypertension may require from 1200 mg to 2400 mg per day, with or without thiazide diuretics. Tell your doctor if your condition does not improve or if it worsens for example, your blood pressure readings remain high or increase. Labetalol hydrochloride HCl is an adrenergic receptor blocking agent that has both selective alpha 1- and nonselective betaadrenergic receptor blocking actions in a single substance. Blood Pressure Monitoring: The blood pressure should be monitored during and after completion of the infusion or intravenous injection. Rapid or excessive falls in either systolic or diastolic blood pressure during intravenous treatment should be avoided. In patients with excessive systolic hypertension, the decrease in systolic pressure should be used as an indicator of effectiveness in addition to the response of the diastolic pressure. Major Surgery: The necessity or desirability of withdrawing beta-blocking therapy before major surgery is controversial. Protracted severe hypotension and difficulty in restarting or maintaining a heartbeat have been reported with beta-blockers. Side Effects List Labetalol HCL side effects by likelihood and severity. Does labetalol oral have side effects? The oculomucocutaneous syndrome associated with the beta-blocker practolol has not been reported with labetalol HCl during investigational use and extensive foreign marketing experience.

A substantial fall in blood pressure on standing should be expected in these patients. The patient's ability to tolerate an upright position should be established before permitting any ambulation, such as using toilet facilities. The usual maintenance dosage of labetalol HCl is between 200 and 400 mg twice daily. Since the full antihypertensive effect of labetalol HCl 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. Do not use more than 5 lozenges in 6 hours or more than 20 lozenges in a day. You may use this product on a regular schedule as well as at times when you have the urge to smoke. The recommended initial dose is 200 mg orally, followed in 6 to 12 hours by an additional dose of 200 or 400 mg orally, depending on the blood pressure response. Dopamine or dobutamine may also be useful. The rate of infusion of the diluted solution may be adjusted according to the blood pressure response, at the discretion of the physician. To facilitate a desired rate of infusion, the diluted solution can be infused using a controlled administration mechanism, eg, graduated burette or mechanically driven infusion pump.
Geriatric: The elderly are more likely to experience when taking labetalol. Labetalol should be dosed with caution in the elderly and counseled on this side effect.

Teratogenic studies have been 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 approximately the MRHD. It is also used as an alternative in the treatment of severe hypertension. Labetalol HCl combines both selective, competitive, alpha 1-adrenergic blocking and nonselective, competitive, beta-adrenergic blocking activity in a single substance. Pregnancy: Studies in lab animals showed no harm to the fetus. However, a comparable well-controlled study has not been performed in pregnant women. R' stereoisomer, makes up 25% of racemic labetalol. Cimetidine has been shown to increase the bioavailability of labetalol HCl administered orally. Since this could be explained either by enhanced absorption or by an alteration of hepatic metabolism of labetalol HCl, special care should be used in establishing the dose required for blood pressure control in such patients. Pediatric: No studies have established safety or usefulness in this population. If cardiac failure continues, despite adequate digitalization and diuretic, therapy with labetalol HCl tablets should be withdrawn gradually, if possible. Detlev Ganten; Patrick J. Mulrow 6 December 2012. The necessity or desirability of withdrawing beta-blocking therapy before major surgery is controversial. Protracted severe hypotension and difficulty in restarting or maintaining a heartbeat have been reported with beta-blockers. The effect of labetalol HCl's alpha-adrenergic activity has not been evaluated in this setting. Since the half-life of labetalol 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 oral labetalol hydrochloride started. 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. The metabolism of labetalol is mainly through conjugation to glucuronide metabolites. The metabolites are present in plasma and are excreted in the urine and, via the bile, into the feces. Approximately 55% to 60% of a dose appears in the urine as conjugates or unchanged labetalol within the first 24 hours of dosing. There is pharmacologic evidence that norepinephrine may be the drug of choice. celexa
Kidney function declines as you grow older. This medication is removed by the kidneys. Therefore, older adults may be more sensitive to the side effects of this drug, including dizziness and lightheadedness.

Food and Drug Administration. WebMD does not endorse any specific product, service or treatment. Cardiac Failure: Sympathetic stimulation is a vital component supporting circulatory function in congestive heart failure. Beta-blockade carries a potential hazard of further depressing myocardial contractility and precipitating more severe failure. Although beta-blockers should be avoided in overt congestive heart failure, if necessary, labetalol HCl can be used with caution in patients with a history of heart failure who are well compensated. Congestive heart failure has been observed in patients receiving labetalol HCl. Labetalol HCl does not abolish the inotropic action of digitalis on heart muscle.

Impaired Hepatic Function: Labetalol HCl tablets should be used with caution in patients with impaired hepatic function since metabolism of the drug may be diminished. 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.
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. Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Beta-blockers may decrease the rate at which aneurysms grow. In general, the risks of surgery to repair smaller aneurysms outweigh the possible benefits, because smaller aneurysms rarely rupture. This is especially important with labile diabetics. Beta-blockade also reduces the release of insulin in response to hyperglycemia; it may therefore be necessary to adjust the dose of antidiabetic drugs. Patients should always be kept in a supine position during the period of IV drug administration. A substantial fall in blood pressure on standing should be expected in these patients.
