1. What Atenolol Orifarm is and what it is used for

Atenolol Orifarm is a so-called selective beta-blocker. Atenolol Orifarm works by reducing the effects of heart-affecting substances (so-called stress hormones) that are formed in connection with mental tension and physical exertion. Atenolol Orifarm has a particular effect on the heart and circulation, while other organs are very little affected. The heart is affected in such a way that it beats more slowly and pumps out less blood per minute. This means that blood pressure is lowered and the number of angina attacks (angina in the heart) is reduced.

Atenolol Orifarm is used for treating high blood pressure, angina pectoris ( angina ), and irregular heartbeat.

Atenolol contained in Atenolol Orifarm may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you use Atenolol Orifarm

Do not take Atenolol Orifarm:

  • if you are allergic to atenolol or any of the other ingredients of this medicine (listed in section 6)
  • if you have untreated heart failure or heart block (a disorder of the cardiac conduction system)
  • if you have very slow or irregular heart activity of a particular type (“sick sinus node”)
  • if you have very low blood pressure
  • if you have poor blood circulation
  • if you have an untreated adrenal tumor
  • if you have been fasting for several days

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before taking Atenolol Orifarm:

  • if you have asthma or another lung disease
  • if you have heart or blood circulation problems
  • if you have shortness of breath
  • if you have swollen ankles
  • if you have a specific type of chest pain called Prinzmetal’s angina
  • if you have diabetes
  • if you have kidney disease
  • if you have a thyroid disease
  • if you have had a severe allergic reaction to, for example, insect bites ( beta-blockers may intensify allergic reactions)

If you have diabetes, you should be aware that Atenolol Orifarm may slow down the increase in heart rate that normally accompanies low blood sugar.

Atenolol slows the heart rate. This is normal, but if you are worried, talk to your doctor.

Never stop treatment without consulting your doctor. If treatment is to be stopped, this should be done gradually according to the doctor’s prescription.

If you are admitted to the hospital, tell your healthcare provider that you are taking atenolol (especially your anesthetist if you are going to have surgery).
