Introduction

Patient Information Leaflet

Tenoretic100 mg/25 mg Tablets

atenolol/clortalidona

Read this leaflet carefully before you start taking this medicine, because it contains important information for you.

  • Keep this leaflet, as you may need to read it again.
  • If you have any questions, ask your doctor, pharmacist or nurse.
  • This medicine has been prescribed for you only, and you must not give it to others even if they have the same symptoms as you, as it may harm them.
  • If you experience any side effects, consult your doctor, pharmacist or nurse, even if they are not listed in this leaflet.

1. What is Tenoretic and what is it used for

Tenoretic is indicated for the treatment of high blood pressure.

Tenoretic contains two active ingredients. Atenolol is a beta-blocker and has effects on your heart and circulation. Clortalidona is a diuretic that increases the amount of urine produced by the kidneys. Each one reduces blood pressure through a different mechanism.

Your doctor may prescribe Tenoretic if your blood pressure is not adequately controlled with atenolol or clortalidona separately.

2. What you need to know before starting to take Tenoretic

Do not take Tenoretic

  • If you are allergic to atenolol, clortalidona or any of the other components of this medication (listed in section 6).
  • If you have or have had heart problems such as heart failure or blockage.
  • If you have ever experienced very slow or irregular heartbeats, very low blood pressure or circulatory failure (cardiac conduction disorder).
  • If you have severe kidney problems.
  • If you have been told you have phaeochromocytoma (a tumor in the adrenal glands) that is not being treated with other medications.
  • If you have fasted.
  • If you have been told you have metabolic acidosis (a metabolic disorder that causes excessive blood acidity).
  • If you are pregnant, think you may be pregnant or are breastfeeding. See “Pregnancy and breastfeeding”.

Warnings and precautions

  • Consult your doctor, pharmacist or nurse before starting to take Tenoretic
  • If you have any health problems such as asthma or breathing difficulties, diabetes, circulatory disorders, gout, heart problems, kidney problems, liver or thyroid problems.
  • If you have ever been told you have a specific type of chest pain (angina) called Prinzmetal's angina.
  • If you have ever had an allergic reaction to something, for example, an insect bite.
  • If you are using eye drops that contain beta-blockers, you may notice a greater effect from Tenoretic.
  • If you are an elderly patient, follow a low-potassium diet or have gastrointestinal problems, your doctor may need to perform blood tests to monitor your potassium or sodium levels in the blood.
  • You may notice that your pulse is slower while taking these tablets. This is normal, but if this concerns you, inform your doctor.
  • If you are diabetic, Tenoretic may alter your response to insulin or other antidiabetic treatments. It may also modify your normal response to low blood glucose, which usually involves an increase in heart rate.
  • Tenoretic may modify the body's response to hypoglycemia (low blood glucose levels), reducing the tachycardia, palpitations and sweating that occur during hypoglycemia.
  • If you experience a decrease in vision or eye pain, these may be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased eye pressure, which can occur within a few hours to a week after taking Tenoretic.If left untreated, this can cause permanent vision loss. If you have previously had an allergy to penicillin or sulfonamide, you may be at a higher risk of developing it.
  • In the event of hospital admission, inform the healthcare staff and, in particular, the anesthetist that you are being treated with Tenoretic.

Taking Tenoretic with other medications

Inform your doctor or pharmacist that you are taking, have taken recently or may need to take any other medication, including those purchased without a prescription, as it may be necessary to interrupt treatment or adjust the dose of one of them. Some medications may affect the action of others, particularly:

  • Disopyramide or amiodarone (for irregular heartbeats).
  • Other treatments for hypertension or angina (particularly, see verapamil, diltiazem, nifedipine, clonidine). If you are taking clonidine for hypertension or to prevent migraines, do not interrupt treatment with this or Tenoretic without consulting your doctor first.
  • Treatment for heart failure (digoxin).
  • Lithium (for certain psychiatric disorders).
  • Anti-inflammatory medications for pain relief (such as indometacin or ibuprofen).
  • Decongestants or other products for colds that you may have purchased yourself at a pharmacy.
  • Baclofen (used as a muscle relaxant).
