Patient leaflet - Propranolol Hydrochloride 10 mg/5 ml oral solution

1. What Propranolol is and what it is used for

Propranolol is one of a group of drugs called beta- blockers. It has effects on the heart and circulation and also on other parts of the body.

Propranolol can be used for many conditions including

  • Hypertension (high blood pressure)
  • Angina (chest pain)
  • Some arrythmias (disorders of heart rhythm)
  • Protection of the heart after a myocardial infarction

    (heart attack)

  • Prevention of migraine
  • Essential tremor, anxiety
  • Certain thyroid conditions (such as thyrotoxicosis,

    which is caused by an overactive thyroid gland)

  • Hypertrophic cardiomyopathy (thickened heart

    muscle)

  • Phaeochromocytoma (high blood pressure due to a

    tumour usually near the kidney)

  • Bleeding in the oesophagus caused by high blood

    pressure in the liver.

2. What you need to know before you take Propranolol

If you have ever had asthma or wheezing, do not take your Propranolol. Go back to your doctor or pharmacist.

Do not take Propranolol if:

  • You are allergic to propranolol or any of the other

    ingredients listed in section 6.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Propranolol.

Propranolol should also not be taken by people with heart failure which is not under control or people with certain other conditions such as heart block, very slow or very irregular heartbeats, very low blood pressure or very poor circulation. It should also not be taken by people who are fasting or have been fasting recently, people who have phaeochromocytoma (high blood pressure due to a tumour usually near the kidney) which is not being treated or by people who have metabolic acidosis or a particular type of chest pain called Prinzmetal’s angina. Your doctor will know about these conditions. If you have one of these conditions, make sure your doctor knows about it before you take Propranolol.

Talk to your doctor, pharmacist or nurse before taking Propranolol if you:

  • Get allergic reactions to such things as insect stings
  • Have diabetes as Propranolol may change your normal

    response to low blood sugar, which usually involves an increase in heart rate. Propranolol may cause low blood sugar levels even in patients who are not diabetic

  • Suffer from unstable angina (non exercise-induced

    sharp chest pain)

  • Have thyrotoxicosis as Propranolol may hide the

    symptoms of thyrotoxicosis

  • Have kidney or liver problems (including cirrhosis of

    the liver) talk to your doctor because you may need to have some check-ups during your treatment

    • Have any other health problems such as circulation disorders, heart problems, breathlessness or swollen ankles.

Other medicines and Propranolol

Tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines. This is because some medicines can affect the way Propranolol works or Propranolol can affect how other medicines work. These medicines include the following:

  • Verapamil
  • Diltiazem
  • Nifedipine
  • Nisoldipine
  • Nicardipine
  • Isradipine
  • Lacidipine (which are used to treat hypertension or angina)
  • Disopyramide
  • Lidocaine
  • Quinidine
  • Amiodarone or propafenone (for irregular heartbeats)
  • Digoxin (for heart failure)
  • Adrenaline (a heart stimulant)
  • Ibuprofen and indometacin (for pain and

    inflammation)

  • Ergotamine, dihydroergotamine or rizatriptan (for migraine)
  • Chlorpromazine and thioridazine (for certain psychiatric disorders)
  • Cimetidine (for stomach problems)
  • Rifampicin (for the treatment of tuberculosis)
  • Theophylline (for asthma)
  • Warfarin (to thin the blood) and Hydralazine (for hypertension).

If you are taking clonidine (for hypertension or migraine) and Propranolol together, you must not stop taking clonidine unless your doctor tells you to do so. If it becomes necessary for you to stop taking clonidine, your doctor will give you careful instructions on how to do it.
