• Drug interactions: Potentially hazardous interactions with other drugs Anaesthetics: enhanced hypotensive effect. Analgesics: NSAIDs antagonise hypotensive effect. Anti-arrhythmics: increased risk of myocardial depression and bradycardia; increased risk of bradycardia, myocardial depression and AV block with amiodarone; increased risk of myocardial depression and bradycardia with flecainide; concentration increased by propafenone and dronedarone. Antibacterials: concentration reduced by rifampicin. Antidepressants: enhanced hypotensive effect with MAOIs; concentration increased by citalopram and escitalopram and possibly by paroxetine - avoid. Antihypertensives; enhanced hypotensive effect; increased risk of withdrawal hypertension with clonidine; increased risk of first dose hypotensive effect with post-synaptic alpha-blockers such as prazosin. Antimalarials: increased risk of bradycardia with mefloquine; avoid with artemether/lumefantrine. Antipsychotics enhanced hypotensive effect with phenothiazines. Antivirals: avoid concomitant use with tipranavir in heart failure. Calcium-channel blockers: increased risk of bradycardia and AV block with diltiazem; hypotension and heart failure possible with nifedipine and nisoldipine; asystole, severe hypotension and heart failure with verapamil. Cytotoxics: possible increased risk of bradycardia with crizotinib. Diuretics: enhanced hypotensive effect. Fingolimod: possibly increased risk of bradycardia. Moxisylyte: possible severe postural hypotension.
