IMPORTANT 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

Antibacterials: concentration reduced by rifampicin

Antidepressants: enhanced hypotensive effect with MAOIs

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

Antipsychotics: enhanced hypotensive effect with phenothiazines

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

Diuretics: enhanced hypotensive effect Moxisylyte: possible severe postural hypotension

Sympathomimetics: severe hypertension with adrenaline and noradrenaline, and possibly with dobutamine
