| FDA dosing | Population | Start | Target | Max |
|---|---|---|---|---|
| Hypertension | adult | 5 mg QD (2.5 mg QD may be appropriate in some, e.g. bronchospastic disease) | 5-10 mg QD (individualized) | 20 mg QD |
Renal CrCl <40 mL/min: initial 2.5 mg QD, cautious titration; not dialyzable — no replacement dose needed on dialysis
Hepatic Hepatitis or cirrhosis: initial 2.5 mg QD, cautious titration
Instructions
- Avoid abrupt cessation — taper over ~1 week under observation
- Geriatric: no age-based adjustment unless significant renal/hepatic dysfunction
Available strengths
- tab 2.5, 5, 10 mg
Contraindications
- Cardiogenic shock
- Overt cardiac failure
- Second- or third-degree AV block
- Marked sinus bradycardia
Cautions
- May precipitate or worsen cardiac failure
- Abrupt cessation can exacerbate angina, MI, or ventricular arrhythmia — taper ~1 week
- Bronchospastic disease: beta-blockers generally not recommended; if needed use lowest dose (start 2.5 mg) with beta2-agonist available
- Can aggravate peripheral vascular disease symptoms
- May mask hypoglycemia (tachycardia) in diabetes
- May mask hyperthyroidism; abrupt withdrawal can precipitate thyroid storm
- Anesthesia/major surgery: impaired reflex adrenergic response
- Caution in renal or hepatic impairment
Adverse reactions
- Bradycardia (dose-related)
- Diarrhea (dose-related)
- Asthenia (dose-related)
- Fatigue (dose-related)
- Sinusitis (dose-related)
- Headache
- Dizziness
- URI, rhinitis, pharyngitis
- Peripheral edema
