Adcirca must not be used in patients who have had an acute myocardial infarction (sudden heart attack) within the last three months, or who have severe hypotension (low blood pressure). Adcirca must not be taken with nitrates (a group of medicines used to treat angina) or medicines of the class ‘guanylate cyclase stimulators’ such as riociguat (another medicine to treat pulmonary hypertension). It must not be used in patients who have ever had loss of vision because of a problem called non-arteritic anterior ischaemic optic neuropathy (NAION) that affects the blood flow to the nerve in the eye.
