Details with Side Effects
Patients, especially those with evidence of coronary artery disease, should be warned against interruption or discontinuation of Sectral (acebutolol) therapy without a physician's supervision. Although cardiac failure rarely occurs in properly selected patients, those being treated with β-adrenergic blocking agents should be advised to consult a physician if they develop signs or symptoms suggestive of impending CHF, or unexplained respiratory symptoms.
Patients should also be warned of possible severe hypertensive reactions from concomitant use of a-adrenergic stimulants, such as the nasal decongestants commonly used in OTC cold preparations and nasal drops.
