• You have an acute heart attack episode (acute myocardial infarction)
• Your blood is not circulating around your body properly (circulatory failure)
• You are suffering from “shock” or collapse of the blood vessels
• You are suffering from any of the following heart conditions:
  • hereditary thickened heart muscle (hypertrophic obstructive cardiomyopathy [HOCM])
  • inflammation of the protective sac surrounding the heart (constrictive pericarditis)
  • build-up of fluid between the heart and its protective sac (cardiac tamponade)
  • low heart (cardiac) filling pressures
  • narrowing of the valves in the heart (aortic/mitral valve stenosis)
  • diseases associated with raised pressure inside the head (intra-cranial pressure)
• You suffer from reduction in red blood cells which can make the skin pale and cause weakness or breathlessness (severe anaemia)
• You have bleeding in the brain (brain haemorrhage)
• You have a head injury (trauma)
• You have severely low blood volume (hypovolaemia)
• You have severely low blood pressure
• You take sildenafil (Viagra) or any other phosphodiesterase-5 (PDE-5) inhibitor drugs used for erectile dysfunction such as tadalafil and vardenafil
• You have an eye disease called closed angle glaucoma
• You take products that contain riociguat, a medicine used in treating pulmonary hypertension.

If any of the above applies to you talk to your doctor or pharmacist.

Elantan LA is not suitable for the treatment of suddenly occurring chest pain (e.g. acute angina pectoris attack). In the event of an angina attack, an under-the-tongue (sublingual) treatment, such as GTN (glyceryl trinitrate) spray or tablet should be used instead of Elantan LA.

Talk to your doctor or pharmacist before taking Elantan LA:

• if you have a recent history of heart attack, or the left side of your heart is not working properly. It is important that blood pressure does not fall too low
• if you suffer from low blood pressure (hypotension) as nitrates can further decrease it, or cause low blood pressure upon standing
• if you have an underactive thyroid gland
• if you are severely underfed (malnourished)
• if you have severe liver or severe kidney disease
• if you suffer from a very low body temperature (hypothermia)
• if you suffer from very poor blood circulation
• if you have slower than normal bowel movements
• if you have an abnormally low level of oxygen in the blood and impaired gas exchange due to lung disease or ischaemic heart failure
• if you are lactose intolerant, as Elantan LA contains lactose.

Organic nitrates have been shown to stop working or become less effective if they are taken continuously at high doses. It is important to closely follow the dosing instructions to avoid this.

Treatment with Elantan LA should not be stopped suddenly. Talk to your doctor before stopping Elantan LA (see section 3).

During treatment with Elantan LA you must not take medicinal products that contain PDE-5 inhibitors (e.g. sildenafil, tadalafil, vardenafil) for the treatment of erectile dysfunction (see section Other medicines and Elantan LA).

During treatment with Elantan LA, drinking alcohol should be avoided because alcohol can enhance the blood-pressure-lowering effect of Elantan LA (see section Elantan LA with food, drink and alcohol).

• Do not take Elantan LA with PDE-5 inhibitors such as sildenafil (Viagra) used for erectile dysfunction. Using Elantan LA with these medicines could cause your blood pressure to fall to a dangerously low level. You must not stop taking Elantan LA to take PDE-5 inhibitors as this will increase your chances of having an angina attack.
• Do not take Elantan LA with products that contain riociguat, a medicine used in treating pulmonary hypertension.

• Medicines to lower your blood pressure such as beta-blockers, calcium channel blockers, vasodilators, alprostadil, aldesleukin, angiotensin II receptor antagonists
• Monoamine oxidase inhibitors (used to treat depression)
• Tricyclic antidepressants (used to treat depression) and neuroleptics (used to treat anxiety)
• Ergotamine used for migraine
• Sapropterin used for phenylketonuria (PKU)
• Any other medicine, including medicines obtained without a prescription.

Alcohol may also potentiate the lowering of blood pressure effect of nitrates.

Do not drink alcohol. It could increase the effect of Elantan LA and lower your blood pressure too much. If this happens, you may feel dizzy or faint.

If you are pregnant, or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

If you have blurred vision or feel dizzy or tired while taking Elantan LA, do not drive or operate machinery. This effect may be increased by alcohol use (see Elantan LA with food, drink and alcohol).

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

Your doctor will choose the dose that is right for you. Your dose will be shown clearly on the label that your pharmacist puts on your medicine. If it does not, or you are not sure, ask your doctor or pharmacist.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
