Interactions ⬆ ⬇

Drug-drug:

General anesthetics, phenytoin, and verapamil may cause additive myocardial depression.
Additive bradycardia may occur with clonidine, digoxin, diltiazem, ivabradine, or verapamil.
Additive hypotension may occur with other antihypertensives, acute ingestion of alcohol, or nitrates.
Concurrent use with amphetamine, cocaine, ephedrine, epinephrine, norepinephrine, phenylephrine, or pseudoephedrine may result in unopposed alpha-adrenergic stimulation (excessive hypertension, bradycardia).
Concurrent thyroid preparation administration may ↓ effectiveness.
May alter the effectiveness of insulins or oral hypoglycemic agents (dose adjustments may be necessary).
May ↓ the effectiveness of theophylline.
May ↓ the beta₁-cardiovascular effects of dopamine or dobutamine.
Use cautiously within 14 days of MAO inhibitor therapy (may result in hypertension).

Patient/Family Teaching ⬆ ⬇

Instruct patient to take medication exactly as directed, at the same time each day, even if feeling well; do not skip or double up on missed doses. If a dose is missed, it should be taken as soon as possible up to 4 hr before next dose. Abrupt withdrawal may precipitate life-threatening arrhythmias, hypertension, or myocardial ischemia.
Teach patient and family how to check pulse and BP. Instruct them to check pulse daily and BP biweekly and to report significant changes to health care professional.
May cause drowsiness. Caution patients to avoid driving or other activities that require alertness until response to the drug is known.
Advise patients to change positions slowly to minimize orthostatic hypotension.
Caution patient that this medication may increase sensitivity to cold.
Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult health care professional before taking any Rx, OTC, or herbal products, especially cold preparations, concurrently with this medication. Patients on antihypertensive therapy should also avoid excessive amounts of coffee, tea, and cola.
Diabetics should closely monitor blood glucose, especially if weakness, malaise, irritability, or fatigue occurs. Medication does not block dizziness or sweating as signs of hypoglycemia.
Advise patient to notify health care professional if slow pulse, difficulty breathing, wheezing, cold hands and feet, dizziness, light-headedness, confusion, depression, rash, fever, sore throat, unusual bleeding, or bruising occurs.
Instruct patient to inform health care professional of medication regimen before treatment or surgery.
Advise patient to carry identification describing disease process and medication regimen at all times.
Rep: Advise females of reproductive potential to notify health care professional if pregnancy is planned or suspected or if breastfeeding.
Hypertension: Reinforce the need to continue additional therapies for hypertension (weight loss, sodium restriction, stress reduction, regular exercise, moderation of alcohol consumption, and smoking cessation). Medication controls but does not cure hypertension.
