1. what slow-k is and what it is used for

Slow-K belongs to a group of medicines called potassium supplements.

Slow-K contains potassium and is used to treat or prevent low levels of potassium in your body. Slow-K tablets are prolonged-release tablets which means that the potassium is released slowly from the tablet.

Whilst on this medicine your doctor will want to measure your blood levels of potassium on a regular basis.

2. what you need to know before you take slow-k do not take slow-k:

  • – if you are allergic to potassium chloride or any of the other ingredients of this medicine (listed in section 6)

  • – if you have been told by your doctor you have kidney failure

  • – if you have Addison’s disease (which is a condition where your adrenal gland is not producing enough steroids)

  • – if you have recently suffered from severe burns

  • – if you suffer from digestive problems or have difficulty swallowing (due to a narrowing or blockage of your gullet (food pipe) or intestines)

  • – if you have been told you have metabolic acidosis (a condition caused by increased acid levels in the blood)

  • – if you are dehydrated (you may feel thirsty with a dry mouth)

  • – if you have high blood potassium levels (which can cause an abnormal heartbeat)

  • – if you suffer from a condition called hyporeninaemic hypoaldosteronism (where your body is low on an enzyme called renin and a hormone called aldosterone which normally helps to control your blood pressure)

  • – if you are taking certain types of diuretics (water tablets); either potassium-sparing diuretics (e.g. triamterene and amiloride) or aldosterone antagonists (e.g. spironolactone and eplerenone).

Warnings and precautions

Talk to your doctor or pharmacist before taking Slow-K if you: – have had an ostomy (an operation to remove part of your bowels) – suffer from any condition which affects your bowel movements – suffer from heart disease (which may cause chest pain, shortness of breath or ankle swelling)

  • – suffer from kidney problems – have or have ever had a stomach ulcer.

Do not give Slow-K to children.

If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist before you take Slow-K.

Slow-K with food and drink

You must take your tablets with fluid during a meal.

Pregnancy and breast-feeding

Your doctor will only give you Slow-K if you really need it. Slow-K is a prolonged-release tablet, which means it takes a long time to dissolve. When you are pregnant your digestive system works more slowly and so Slow-K tablets take longer to pass through your system. This could mean you do not receive the correct amount of potassium from your Slow-K tablets.

Slow-K should not be taken during breast-feeding unless your doctor considers that the benefits for you are greater than the risks to the child.

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.

Slow-K contains sucrose

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

3. how to take slow-k

Always take this medicine exactly as described in this leaflet or as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

The usual dose is 2 to 3 tablets a day. Your doctor will decide when and how to treat you with Slow-K. Your doctor may tell you to take up to 12 tablets a day.

  • – The tablets should not all be taken at once but spread out during the day and taken with your meals.

  • – Take your tablets with fluid during a meal and whilst sitting upright.

  • – Swallow them whole.

  • – Do not break or chew them. This is important as the tablets release potassium slowly. If you chew the tablets, this could damage the tablet and let the potassium out too quickly and this could cause stomach problems.

If you take more Slow-K than you should

If you accidentally take too many tablets, or someone else takes your medicine, you should tell your doctor at once or contact your nearest accident and emergency department. Show any left-over medicines or the empty packet to the doctor.

If you forget to take Slow-K

Do not worry. If you forget to take a dose, take it as soon as possible, unless it is almost time to take the next dose.

Do not take a double dose. Then go on as before.

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