How should I take SOTACOR?

If you have been prescribed SOTACOR tablets, you must be sure to follow your doctor's instructions very carefully.

Do not stop taking SOTACOR tablets suddenly, the dose needs to be reduced gradually over 7 to 14 days.

Your doctor will decide on the dose of SOTACOR tablets for you, and may need to change the dose a few times to get the best level for you.

The usual dose is 80mg to 160mg twice a day. Your doctor may need to increase this as a very few patients may need up to three to four 160mg tablets spread over a day. The dosage may need to be different if you have a kidney problem.

You should take SOTACOR TABLETS with water one to two hours before meals. Do not take SOTACOR with milk or meals.

It is important not to miss a dose of SOTACOR but if you do, take your next dose at the normal time and with the normal amount.

If you have been prescribed SOTACOR injection, you will most likely be in hospital. Your doctor will have worked out the dose you require and the injection will be given to you by a doctor or a nurse. It will be given into a vein. The injection may be repeated if necessary.

You should not drink alcohol while you are on SOTACOR.

Should I take SOTACOR with other medicines?

What side effects might SOTACOR cause?

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking SOTACOR.

SOTACOR helps most people with arrhythmia, but it may have unwanted side effects in some people. Rarely, serious heart problems can develop while you are taking normal doses of SOTACOR but you must remember that you are taking SOTACOR because your heart already has a serious problem. It is very important that your doctor keeps a check on your progress.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor if you notice any of the following and they worry you:

  • dizziness, lightheadedness or fainting, especially when you get up from a sitting or lying position. Getting up slowly may help.
  • tiredness, lack of energy, weakness
  • headache, fever
  • irritated eyes, blurred vision, worsening of eyesight, increased sensitivity of the eyes to sunlight
  • feeling sick, vomiting, stomach upset, diarrhoea, wind
  • change in taste sensation
  • anxiety, depression, mood changes
  • problems with sexual function
  • sleep problems, unusual dreams
  • worsening of psoriasis
  • hearing disturbances
  • tingling or numbness in the hands or feet, cold limbs

Tell your doctor immediately or go to casualty at the nearest hospital if you notice any of the following:

  • chest tightness, wheezing, shortness of breath
  • very slow heart beat
  • fast, irregular heart beat, palpitations
  • chest pain
  • any type of skin rash, itching
  • shortness of breath (sometimes with tiredness, weakness and reduced ability to exercise), which may occur together with swelling of the feet or legs due to fluid build up

This is not a complete list of all possible side effects. Others may occur in some people and there may be some side effects not yet known.

Tell your doctor if you notice anything that is making you feel unwell while you are taking, or soon after you have finished taking SOTOCOR, even if it is not on this list.

What should I do if someone takes an overdose of SOTACOR?
