Labetalol (Normodyne)

Labetalol is a medication that blocks alpha1-, beta1-, and beta2-adrenergic receptor sites to slow heart rate, decrease blood pressure and peripheral vascular resistance. Common side effects include drowsiness, dizziness and fatigue while rare side effects include altered taste and paresthesia. Nurses should monitor the patient's blood pressure, heart rate and EKG for hypotension and arrhythmias when administering this medication intravenously.

100200 mg twice daily

Route & IV Q6H is BP >160
Frequency
Action of Blocks alpha1-, beta1-, beta2- (large doses) adrenergic receptor sites. Large
Medication doses increase airway resistance.
Therapeutic Effect: Slows sinus heart rate; decreases peripheral vascular
resistance, cardiac output, B/P.
Side Effects Frequent (20%11%): Drowsiness, dizziness, excessive fatigue. Occasional
(10% or less): Dyspnea, peripheral edema, depression, anxiety, constipation,
diarrhea, nasal congestion, weakness, diminished sexual function, transient
scalp tingling, insomnia, nausea, vomiting, abdominal discomfort. Rare:
Altered taste, dry eyes, increased urination, paresthesia.
Nursing Assess baseline renal/hepatic function tests. Assess B/P, apical pulse
Considerations immediately before drug administration (if pulse is 60/min or less or systolic
B/P is lower than 90 mm Hg, withhold medication, contact physician).
Monitor B/P for hypotension. Assess pulse for quality, irregular rate,
bradycardia. Monitor EKG for cardiac arrhythmias. Monitor daily pattern of
bowel activity, stool consistency. Assist with ambulation if dizziness occurs.
Assess for evidence of HF: dyspnea (particularly on exertion or lying down),
night cough, peripheral edema, distended neck veins. Monitor I&O (increase
in weight, decrease in urine output may indicate HF).

IV Push: Diluent: Administer undiluted. Concentration: 5 mg/mL.


Rate: Administer slowly over 2 min.
