2. BEFORE YOU TAKE TENSIKEY 20 mg tablets.

Do not take TENSIKEY if:
• You are allergic to lisinopril, to other medicines of the same group (ACE inhibitors), or to any component of this medicine.
• You have previously received a medicine of the same group as lisinopril (ACE inhibitors) and has had an allergic reaction that caused hand, foot, ankle, face, lip, tongue and/or throat swelling with difficulty to swallow or breath, or if you or a member of your family has had a similar reaction (angioedema).
• You are pregnant. (See section “Pregnancy and breast-feeding”).

Be especially careful with TENSIKEY:
• If you had coarctation of the aorta (aortic stenosis), of renal arteries (renal artery stenosis), or of the heart valves (mitral valve stenosis), or an increase in heart muscle thickness (hypertrophic myocardiopathy).
• If you suffer from acute myocardial infarction.
• If you had renal impairment or if you are on dialysis.
• If you suffer from hepatic failure.
• If you suffer from blood vessel disease (collagen vascular disease) and/or if you are under treatment with allopurinol (for gout disease), procainamide (for heart rate alterations), immunosuppressors (medicines that suppresses the immunological response of the body).
• If you have diabetes.
• If you follow a diet without salt, take potassium supplements, potassium-sparing diuretics or potassium substitutes containing potassium, or if you have recently suffered from excessive vomiting or diarrhoea.
• If you have cough.
• If you are going to follow a treatment called low-density lipoproteins aphaeresis, or a desensitisation treatment to reduce the effect of allergy to bee or wasp itching.
• If you have low blood pressure (you can notice this in form of faints or dizziness, especially in initial doses and when standing up. In these cases, lying down might help you.)

In all these cases, inform your doctor, as you may need a dose adjustment or stopping medication with TENSIKEY.

Stop taking TENSIKEY and immediately call for medical assistance if you have difficulty to breath or swallow with or without face, lip, tongue and/or throat swelling.
