Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about VELTASSA. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you being given VELTASSA against the expected benefits it will have for you.

If you have any concerns about being given this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What VELTASSA is used for

VELTASSA contains the active ingredient patiromer (as sorbitex calcium).

VELTASSA is used to help remove excessive amounts of potassium from the blood (hyperkalaemia). It works by binding extra potassium in your digestive tract. This increases the amount of potassium excreted and thus lowers potassium levels in your blood.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

Before you take VELTASSA

When you must not take it

Do not take VELTASSA if you have an allergy to patiromer sorbitex calcium or any of the ingredients listed at the end of this leaflet.

Some symptoms of an allergic reaction include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips or tongue or other parts of the body
  • rash, itching, or hives on the skin

Do not take it after the expiry date (EXP) printed on the pack. If you take it after the expiry date has passed, it may not work as well.

Do not take it if the packaging is damaged or shows signs of tampering.

If you are not sure whether you should take VELTASSA, talk to your doctor or pharmacist.

  • problems swallowing
  • severe stomach and/or bowel problems

Do not give this medicine to a child under the age of 18 years. Safety and efficacy of VELTASSA in children below the age of 18 years have not yet been established. Therefore, VELTASSA is not recommended in this age group.

Tell your doctor if you are pregnant or plan to become pregnant or are breast-feeding. Your doctor can discuss with you the risks and benefits involved.

If you have not told your doctor about any of the above, tell him/her before you take VELTASSA.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket, health food shop, naturopath, herbalist or internet.

Veltassa may affect other medicines taken by mouth if they are taken too close together. This can cause you to have too little of other medicines in your body which may affect the way your other medicines work. Therefore, take Veltassa at least 3 hours before or after taking any other medicine by mouth.

Your doctor and pharmacist have more information on medicines to be careful with or avoid when taking VELTASSA.

How to take VELTASSA

How much to take

The recommended dose is:

  • starting dose: 8.4 g patiromer once daily
  • maximum dose: 25.2 g patiromer once daily

Your doctor may adjust the dose during the treatment course depending on the potassium level in your blood.

How to take VELTASSA

Mix VELTASSA with water and stir to a suspension of uniform consistency, as follows:

  • Pour half of the water into a glass, then add VELTASSA and stir.
  • Add the remaining half of the water and stir thoroughly. The powder will not dissolve and the mixture will look cloudy.
  • Add more water to the mixture as needed for desired consistency.
  • Drink the mixture immediately. If powder remains in the glass after drinking, add more water, stir and drink immediately. Repeat as needed to ensure the entire dose is taken.

Apple juice or cranberry juice can be used instead of water, if preferred. Other liquids containing high levels of potassium cannot be used.

Take the prepared VELTASSA suspension with or without food and preferably at the same time each day.

Never heat VELTASSA or add it to heated foods or liquids.

Do not take VELTASSA in its dry form.

If you forget to take it

If you stop taking it

Do not stop taking the medicine without your doctor’s approval, as your potassium blood level may increase.
